Dendrobium huoshanense is a precious medicinal plant belonging to Dendrobium of Orchidaceae. It is a special medicinal material and extremely scarce in Huoshan county, Anhui province. At present, D. huoshanense has been greatly protected, which also makes it possible to industrialize relying on tissue culture and artificial cultivation technology. Three main planting methods were utilized for cultivating D. huoshanense including facility cultivation, under forest cultivation and simulative habitat cultivation. Firstly, the three cultivation modes and technical characteristics of D. huoshanense were compared and analyzed, and it was found that the ecological environment of D. huoshanense cultivated in the simulated environment was closer to that of wild D. huoshanense. Secondly, based on comparing the characters and quality of three cultivation modes, the results showed that the shape of D. huoshanense cultivated in simulated environment was more similar to that of "grasshopper thigh" recorded in Bencao Jing Jizhu, and its quality was better than that of facilities and under forest cultivation. The comprehensive benefit comparison of three modes showed that the simulated cultivation had high income, the lowest input-output ratio and significant economic benefit. The quality of cultivated D. huoshanense was further evaluated from four aspects of "excellent environment" "excellent shape" "high quality" "excellent effect", which summarized the comprehensive advantages of simulative habitat cultivation of D. huoshanense as follows: the original habitat and site environment of simulated wild D. huoshanense, the closer shape to the wild, the more content of main medicinal components, and higher economic benefit and better efficacy. The quality of D. huoshanense was improved by the use of simulative habitat cultivation, which has practical significance to guide its large-scale cultivation.

We now enjoy an affluent, comfortable and efficient lifestyle that human beings have long dreamt of. And yet we feel lurking anxiety about the present and the future. Some youths do not have any definite aim in life or foresight, and some people are alarmed by nature destruction, environmental pollution, erratic climate change, global warming and so on.When it comes to medical care, there are serious shortages of physicians in rural areas and in specific departments such as obstetrics and gynecology and pediatrics. The average life expectancy of Japanese has increased, but various forms of disease including cancer and dementia debase the quality of life.Affluent urban life today is supported by the countryside, which undertakes foodproduction and preserves the natural environment. The government should make more efforts to correct disparities between urban and rural areas in population, economics, culture, and medical care.We live now at a crossroads in the 4-billion-year long history of life on the earth. The thread of genes has continued to the pressent. It must be handed down to posterity. Advances in medical technology have contribute greatly to the protection of our life and genes. Indigenous forests have unsophisticatedly fostered our health, physical and mental, soul, and have protected our genes.We humans and other animals alike are consumers in the ecosystems on the earth. Greenplants are the only producers, and bacteria and fungi are decomposers. Green plants, especially multi-layered native forests that enrich green plants, are the very foundation of human existence.Japanese were particularly zealous in protecting and bequeathing native forests in each community, and reforesting after destroying forests to construct paddy fields, roads and villages just as other peoples did in other partsof the world.Native forests in most areas of Japan are laurel forests. Main tree species of laurel forests have evergreen thick watery leaves and deep taproots grabbing thesoil. So, multi-layered native forests have the function of environmental protection including noise insulation, windbreaking, air and water purification, and water retention, as well as the function of disaster mitigation, minimizing damage from storms, earthquakes, fires and tsunamis.Forests absorb CO2 in the air through photosynthesis and fix carbon as an organic compound in the tree body. This helps curb global warming. In the age of deteriorating biodiversity, it is worthy of special mention that there are so many tree species and so many species of birds, insects and small animals in an indigenous forest as well as bacteria and fungi living in the soil. Thus, indigenous forests maintain rich biodiversity, and are the real green environments that protect our life, heart and genes.However, indigenous forests are rapidly vanishing from almost all the areas of the world. Where native forests still remain, they should be preserved. Where native forests are destroyed, they should be restored and regenerated by all possible mean. We conduct phytosociological field surveys to determine main tree species of a given district, nurse their potted seedlings until theroot system fully develops in the containers, and plant them mixed and densely with local citizens. In this ecological plantation survival rate is good, and seedlings grow steadily to form a quasi-natural forest in 10-15 years.Every one of us should plant seedlings for ecological reforestation here and now, especially around hospitals and clinics, and spread the reforestation movement to the whole world to protect our own life, heart and genes.

To clarify the difference of soil moisture characteristics between mixed broad leaf-conifer forest soil and artificial cultivation of Notopterygium incisum, the HYPROP system and the dew point potential meter were used to determine soil water retention curves(SWRC) for samples of two horizons(i.e. 2-7 cm, 10-15 cm). The basic physical and chemical properties of soil and its water characteristic parameters were also determined. The result showed as fllows:①The bulk density of mixed coniferous-broad leaf forest soil was between 0.33 and 0.52 g·cm~(-3), significantly lower than the corresponding value of field soil(1.01-1.18 g·cm~(-3))(P<0.05), While the organic matter content was significantly higher than the corresponding value of field soil(P<0.05). ②The saturated water content(θ_s), field water holding capacity(θ_(FC)) and Water that can be effectively utilized by plants(θ_(PAC)) of mixed coniferous-broadleaved forest soil were significantly higher than the corresponding value of field soil(P<0.05), while the retained water content(θ_r) value that cannot be effectively utilized by plants was significantly lower than that of field soil(P<0.05). ③The values of structural porosity(0.13-0.24 cm~3·cm~(-3)) and Matrix porosity(0.34-0.44 cm~3·cm~(-3)) of mixed coniferous-broadleaved forest soil were higher than the corresponding values of field soil. Therefore, with low bulk density and high content of organic matter, mixed coniferous-broadleaved forest soil can store more water in soil in the form of effective water to meet the needs of plants for water, thus possibly forming high quality medicinal materials of Notopterygii Rhizoma et Radix. In conclusion, the results of this study can provide theoretical basis guidance for soil structure improvement and water management to form high quality medicinal materials in the artificial cultivation of N. incisum.

The ecological environment is closely related to the growth and quality of authentic medicinal materials. Ginseng is very strict with its natural environment and grows mostly in the damp valleys of forests, and the appearance and chemical composition of ginseng under different growth environments are very different. This article reviews the effects of different ecological factors(including light, temperature, altitude, moisture, soil factors, etc.)on the appearance and chemical composition(mainly ginsenosides) of ginseng. Through systematic review, it is found that soil physical factors are the most important ecological factors that affect the appea-rance of ginseng, and soil bulk density plays a key role; temperature affects ginsenosides in ginseng medicinal materials The dominant ecological factors for the accumulation of chemical ingredents; strong light, high altitude, high soil moisture, low soil nutrient and strong acid soil can influence the accumulation of secondary metabolites in ginseng. Environmental stress can also stimulate the formation and accumulation of secondary metabolites in medicinal plants. Appropriate low temperature stress, high or low water stress, acid or alkali stress can also promote the accumulation of ginsenosides. This article systematically reviews the ecological factors that affect the appearance and chemical composition of ginseng, and clarifies the dominant ecological factors and limiting factors for the formation of ginseng's appearance and quality, as well as beneficial environmental stress factors, in order to provide a theoretical basis for ginseng ecological planting and ginseng quality improvement.

The wood decay fungi are a diverse taxonomic group that plays a pivotal role in forest carbon cycling. Wood decay fungi use various enzymatic pathways to digest dead or living wood in order to obtain carbon and other nutrients and these enzymatic systems have been exploited for both industrial and medical applications. Over 600 wood decay fungi species have been described in Korea; however, the recent application of molecular markers has dramatically altered the taxonomy of many of these wood decay fungi at both the genus and species levels. By combining molecular methods, specifically sequences of the internal transcribed spacer region, with traditional morphological characters, this study identified five new species records for Korea in five genera: Aurantiporus, Favolus, Neofavolus, Loweomyces, and Hymenochaetopsis. Three of these genera (Aurantiporus, Favolus, and Loweomyces) were previously unknown in Korea. The relatively simple morphology of the wood decay fungi often leads to ambiguous taxonomic assignment. Therefore, molecular markers are a necessary component of any taxonomic or evolutionary study of wood decay fungi. Our study highlights the need for a more robust and multifaceted approach in investigating new wood decay fungi in Korea.

The objective of this study was to describe general approaches for intervention meta-analysis available for quantitative data synthesis using the R software. We conducted an intervention meta-analysis using two types of data, continuous and binary, characterized by mean difference and odds ratio, respectively. The package commands for the R software were “metacont”, “metabin”, and “metagen” for the overall effect size, “forest” for forest plot, “metareg” for meta-regression analysis, and “funnel” and “metabias” for the publication bias. The estimated overall effect sizes, test for heterogeneity and moderator effect, and the publication bias were reported using the R software. In particular, the authors indicated methods for calculating the effect sizes of the target studies in intervention meta-analysis. This study focused on the practical methods of intervention meta-analysis, rather than the theoretical concepts, for researchers with no major in statistics. Through this study, the authors hope that many researchers will use the R software to more readily perform the intervention meta-analysis and that this will in turn generate further related research.

This study is aimed to reveal the rhizosphere soil fungal community structure difference of Coptis chinensis cropping between natural forest and artificial shed modes, and provide theoretical guidance for soil improvement and C. chinensis planting. The rhizosphere soil samples of 1-5-year-old C. chinensis under natural forest and artificial shed modes were collected. Illumina high-throughput sequencing technology was used to analyze the community structure and diversity of soil fungi under the tow cropping modes,and the effects of soil nutriment indices on soil fungal community structure. The results suggested that the abundance and diversity of fungal communities in soil of 2-5-year-old C. chinensis were not significant different in both two cropping modes, but it was significantly higher than that in the 1-year-old C. chinensis. Comparing soil samples from the same year-old C. chinensis under the two cropping modes, it was found that there was no significant difference in the abundance and diversity of fungal communities. The fungal community of the rhizosphere soil was different in composition and abundance between tow cropping modes, and between different planting years. The 17 phyla,59 classes and 155 orders,and 17 phyla,59 classes and 157 orders were detected in the rhizosphere soil of C. chinensis under the cropping modes of natural forest and the artificial shed, respectively. Ascomycota, Basidiomycota and Mortierellomycota were dominant phyla in rhizosphere soil, and the average abundance of the 3 phyla accounted for 74.36% and 74.30% of the total fungi. The results of analysis of similarities showed that there were significant differences in the fungal community structure of 1-year-old and 2-year-old C. chinensis soil fungi, and there was no significant difference in the community structure of 3-5-year-old samples. Under the natural forest cropping mode, there were significant differences among the samples of different years. Under the artificial shed cropping, there were significant differences in fungal community structure between 1-year-old and 3-5-year-old C. chinensis soil, and between 2-year-old and 3-5-year-old C. chinensis soil. The results of canonical correlation analysis showed that soil pH and soil organic matter content were the main factors affecting the soil fungal community structure. Soil organic matter content was positively correlated with Basidiomycota and Cryptomycota, pH was negatively correlated with Basidiomycota and C. ryptomycota. The planting of C. chinensis has promoted the diversity and abundance of rhizosphere fungal community significantly. For the same year-old C. chinensis soil, abundance of fungal community was no significant difference between two cropping modes. There are significant differences in the rhizosphere soil fungal community structure between tow cropping modes in the first two years of planting. Through the interaction between the rhizosphere and the soil and the continuous selection of the rhizosphere to the fungal community, the fungal community structure tended to be the same between the two cropping modes in rhizosphere soil of 3-5-year old C. chinensis. The soil pH and orga-nic matter content were the main factors affecting the change of fungal community structure.

The natural forest and artificial shed are the main cropping modes of Coptis chinensis. This study is aimed to reveal the rhizosphere soil bacterial community structure difference between under tow C. chinensis cropping modes-natural forest and artificial shed, and to assist us to completely understand soil quality condition,and provide theoretical guidance for soil improvement and C. chinensis planting. The rhizosphere soil samples of 1-5-year-old C. chinensis under tow cropping modes-natural forest and artificial shed were collected. Illumina high-throughput sequencing technology was used to analyze the alpha diversity, community composition, community structure of soil bacteria under the tow cropping modes,and the effects of soil nutriment indices on soil bacterial community structure. Through the analysis of species number, Shannon, Chao1 index and ACE index of bacterial community, it was found that the bacterial diversity of 1-year-old C. chinensis soil under natural forest cropping mode was significantly lower than that under artificial shed cropping mode, and the diversity of bacterial communities in soil of 2-5-years old C. chinensis were not significant different between two cropping modes. A total of 53 phyla,60 classes,140 orders and 266 families were detected in the rhizosphere soil of C. chinensis under the cropping modes of natural forest, respectively. The rhizosphere soil of C. chinensis under the cropping modes of artificial shed included 54 phyla,65 classes,140 orders and 264 families, respectively. Under the two cropping modes, the top 10 dominant species of bacterial community abundance are the same, they are Proteobacteria, Acidobacteria, Actinobacteria,Bacteroidetes, Planctomycetes, Chloroflexi, Verrucomicrobia, Gemmatimonadetes, Firmicutes and Cyanobacteria, but there are differences in the abundance sequence. The top 10 dominant species of bacterial community abundance accounted for 74.36% to 74.30% of the total bacteria, and 3.15% to 3.92% of the bacteria are unclassified. The results of Metastat analysis showed that the abundance of Gemmatimonadetes in the rhizosphere soil of C. chinensis under the cropping modes the artificial shed was significantly higher than that under the natural forest cropping mode(P<0.05). MRPP analysis of community structure differences showed that under tow cropping modes, there were significant differences in the bacterial community structure of 1-4-year-old soil bacteria, among which the difference between 1-year-old soil samples was the largest. With the increase of cropping years, the difference gradually decreases, and there is no significant difference in the bacterial community structure between 5-year-old soil samples. RDA analysis and correlation analysis of bacterial community structure and soil physical and chemical properties showed that the order of environmental factors on the rhizosphere soil bacteria of Coptis chinensis was: pH>available P> total P> total K>bulk density>total N>available N>organic matter. The results are helpful to understand the soil health of C. chinensis and provide scientific basis and theoretical guidance for soil improvement and C. chinensis planting.

This study proposed a rapid method to quantify the colonization rate of arbuscular mycorrhizal fungi (AMF) in plant roots. The method involved the use of an image analysis software (WinRHIZO Pro). The colonization rate is defined as the ratio of the fungal body to the plant root area in a micrograph. Three seedlings of Chengiopanax sciadophylloides, a woody species that accumulates radiocesium, were collected from a secondary forest in the Yamakiya district of Kawamata, Fukushima Prefecture during May–September 2014. The colonization of AMF structures was examined under a light microscope, and the percentage of colonization was determined using the WinRHIZO method. The superiority of the new method was verified by comparing with a modified grid-line intersect method. The colonization of AMF was confirmed in all the seedlings, and a significant coefficient of determination (R² = 0.94) was found with both the methods. The results suggested that the WinRHIZO method is reliable for estimating the colonization of AMF in C. sciadophylloides.
