Hormesis describes the low-dose stimulation and high-dose inhibition phenomena for all kind lives under toxicity environment. This paper generalized hormesis of medicinal plant on grow and metabolite after introducing the concept and study state of hormesis and analyzing hormesis mechanism and its significance. It points out that hormesis can be well used for medicinal plants growth, including increasing the metabolise, giving a dereaction for cultivated field chosen, guiding the agriculture management during the cultivation and improving the anti-stress.

OBJECTIVETo find out the present situation and the development trend special fertilizer of the traditional Chinese medicina plants.

METHODBy consulting a great deal of literatures on special fertilizer and fertilization on traditional Chinese medicine herbs, and based on the scientific research and manufacture experience of the author, and the theoretic actuality of the researches on the fertilization of traditional Chinese medicine herbs, the present study of the special fertilizer inside and outside of our country was analyzed.

CONCLUSIONThe view points of developing special fertilizer for Chinese traditional medicine were put forward, and the development trend of special fertilizer for traditional Chinese medicine herbs was forecasted.

OBJECTIVETo increase inoculation rate of Cistanche tubulosa in the field by studying inoculation technologies.

METHODRoot-tube inoculation methed was used on field experiments. Inoculation rate of C. tubulosa was compared to different size seeds and inoculation mediums and inoculation time.

RESULT AND CONCLUSIONMay is suitable inoculation time. The inoculation rate of C. tubulosa is 92.5% while the seed width is more than 0.7 mm and coarse sand is selected during inoculation period.

OBJECTIVETo understand the process of Cistanche tubulosa.

METHODThe process of seed germination and parasitism was observed using stereomicroscope.

RESULTSeedling of C. tubulosa sprouted after forty day without host root's contact in fields, a tube-like-organ formed and grew auger-type from host root, the tuber apex where touches host root swelled and formed haustorium. Haustorium intruded host root epidermis and vascular bundles, and released brown substances. Then, embryo bud with six or more young leaves formed, finally the swelled tuber-like-organ broken and seed coat shed. Due to the parasitism of C. tubulosa, the host root near stem site swelled, but the other part, shrunk and disappered gradually.

CONCLUSIONSeed of C. tubulosa could germinate indepently in fields. Tuber-like-organ formatin, haustorium formation and bud formation are key steps of C. tubulosa seedling development.

OBJECTIVEThe experiments were conducted to study specialty of seed germinating, plant growing and developing and cultural practices of A. edgeworthii.

METHODThe germinating and sowing test, growth habitants, photosensitive reaction of seedling from subterraneous seeds and above ground seeds on A. edgeworthii were studied in this experiment.

RESULT AND CONCLUSIONThe results indicated that (1) The water could not be absorbed by seed from plant above ground; (2) The underground and above ground seeds could normally germinate, grow, blossom and bear fruits, A. edgeworthii sowed in early May, blossomed in early September and matured in the last ten days of October; (3) The seed leaf of seedling grew underground; (4) The underground seed was produced from subterraneous branch stem which developed from node of seed leaf; (5) A. edgeworthii was shade demanding, high-temperature sensible short-day light plant. The flowering could be greatly advantaged by short-day light treatment (12, 10, 8, 6 h). Cultural practices were studied also in this experiment.

Based on the conception and theory of ecological niche, authors analyzed the cause of the allelopathy and soil sickness of medicinal plants and the relationship between them. Methods to resolve problems in the cultivating medicinal plant was found, that is to construct the ecological niche based on allelopathy theory and avoid the soil sickness.

OBJECTIVETo investigate the origin of medicinal plants in Guizhou province, revise the incorrectly recorded species, and correct the erroneous and incomplete Latin names.

METHODExamination was implemented on species, Latin name and geographical distribution of medicinal plants recorded in 'Medicinal Material Resources of Guizhou'.

RESULTIt was found that 98 species and 4 varieties were absent in Guizhou province or their Latin names were incorrect in 17 families.

CONCLUSIONThe origin of medicinal plants in Guizhou province was studied and the incorrect Latin names were revised. It provides a basis for standardization of medicinal plants in Guizhou province.

The bionic cultivation of medicinal plant is an ecological cultivation pattern, which is adopting ecological engineering and modern agricultural techniques to simulate the natural ecosystem of wild medicinal plant community, and has been given greater attention on the agriculture of traditional Chinese medicine (TCM). It is also the cross subject that combines Chinese traditional medicine, agronomy, horticulture, ecology, agricultural engineering and management. Moreover, it has significant technology advantages of promoting the sustainable utilization of medicinal plant resources, improving the ecological environment and harmonizing man and nature. So it's important to develop the bionic cultivation of TCM.

The medicinal plant resource reserve refers to the natural resources of medicinal plants in a certain time and a certain region within the scope of the volume. In recent years, with the demand of medicinal plant resources surging and the change of the environment and human intervention factors, the medicinal plant resources reserve had accelerated pace of change. It is the prerequisite and basis for the development and utilization of medical plants that how to quickly and accurately attain reserve of some medicinal plants resources, the selection of suitable and accurate estimating method is reliable basis and can guarantee medicinal plant reserve survey, and also is one of the key reserve investigation of success. This paper systematically summarized the estimation method of medicinal plants in recent 30 years, and discussed the basic principle, the estimation model of development and evolution, advantages and disadvantages and applicability, and it aimed to improve the accuracy about reserves survey of medicinal plant resources, and provide scientific and reliable support data to medicinal plants resources for sustainable development and utilization of resources.

The review deals with the phenomenon of autotoxicity in medical plants. The autotoxic potential could be attributed to direct inhibition of plant growth and some diseases could be promoted by autotoxin. Factors affecting autotoxicity include species and cultivars, soil microbes, plant's nutrient situation and soil type etc. Autotoxicity could be overcome or alleviated by plant residues removal, adding beneficial microbes, using organic fertilizer, proper rotation, and grading management to different plant' autotoxic force.
