OBJECTIVEThe effect of the different fertilizing levels on yields and main active components of Pinellia ternata from Sichuan was studied under the cultivated condition, in order to provide theoretical basis for the standardized cultivation.
METHODUsing one of the wild populations of P. ternate from Sichuan as tested material, the experiment was performed with orthogonal designing methods L25 (5(3)). During growth and development period, agronomic traits such as number of sprouting, inflorescence and bulblets were counted. After harvesting, main chemical compositions, growth and proliferation rates were determined.
RESULTIn different fertilizing levels, the P. ternata from Sichuan showed the same growth rhythm, though there were significant difference (P < 0.05) among the average emergence rate,whereas extremely significant difference (P < 0.01) were detected among the average ratio of bolting, the average bulbils, individual growth rate, individual proliferation rate, beta-sitosterol and alkaloid content under different fertilizing levels. Nitrogenous fertilizer that affected the content of alkaloids and beta-sitosterol were extremely significant (P < 0.01), whereas phosphate and potassium fertilizer had no significant effect. The effect of fertilizer factor and inter effects on beta-sitosterol showed no significant effect, but have influence on other indexes.
CONCLUSIONThe optimum fertilizer composition was 315 kg x hm(-2) of nitrogen, 225 kg x hm(-2) of P2O5 and 270 kg x hm(-2) of K2O.

The output and agronomic characters of 3-year-old Panax notoginseng cultured under stereo structure (upper, middle and down layers) were investigated, and the annual change of N, P and K of its planting soil were also studied. Results showed that, compared with field cultured Panax notoginseng, growth vigour and output of stereo-cultivation were significantly lower. But the total production of the 3 layers was 1.6 times of field. The growth vigor and production of P. notoginseng was in the order of upper layer > middle layer > down layer. The content of ginsenoside in rhizome, root tuber and hair root of P. notoginseng was in the order of upper layer > field > middle layer > down layer. Organic matter content and pH of stereo-cultivation soil decreased with the prolonging of planting time, which with the same trend of yield. Organic matter content of stereo-cultivation soil was significantly higher than field, but the pH was significantly lower. Contents of total and available N, P and K in stereo-cultivation soil and field decreased with the prolonging of planting time. The content of N and P were in the order of upper layer > middle layer > yield > down layer, the content of K was in the order of upper layer > middle layer > down layer > yield. Compared with field, the proportion of N and P in the organ of underground (rhizome, root tuber and hair root) of upper layer were increased, while decreased in middle and down layers. Proportion of K in underground decreased significantly of the 3 layers. In conclusion, the agronomic characters and production of stereo-cultivation were significantly lower than that of yield. But the total production of the 3 layers were significantly higher than field of unit area. And the aim of improving land utilization efficiency was achieved. Nutritions in the soil of stereo-cultivation were enough to support the development of P. notoginseng, which was not the cause of weak growth and low production. The absorbing ability of P. notoginseng to N, P and K nutrients was decreased by stereo-cultivation mode. So, improve the growth vigour of P. notoginseng from the perspective of adjusting the stereo-cultivation mode so as to improve the nutrient absorption capacity is the future direction.

OBJECTIVETo study the absorption and transformation of N, P, K and plant growth as well as the accumulation of active ingredients in Angelica dahurica var. formosana from Sichuan province and provide basis for rational fertilization.
METHODSamples were collected in different growth phrases, and correlative morphological indexes, the contents and accumulations of N, P, K and active ingredients were determined.
RESULTThe vegetative growth period of A. dahurica var. formosana sowed in autumn could be preliminarily divided into three phases: seedling period, aerial-part peak growth period and root peak growth period. With the development, the plant height and aerial part dry weight increased at the earlier stage, and then decreased. But the root length, root diameter, and root dry weight increased. The absorptive capacity of N, P and K varied among different developing stages. In general, the absorptive capacity of N and K was the higher than that of P. The order of total nutrition accumulation was N > P > K, the accumulation of N, P and K in aerial part decreased gradually during the growth period, while the accumulation of N, P and K in root increased gradually. The concentration of imperatorin and isoimperatorin showed decreasing-increasing-decreasing-increasing trend, while the accumulation of them increased gradually. And the correlation analysis results showed that the accumulation of P and K in aerial part had positive correlation with the concentration of imperatorin in root, the accumulation of N, P and K in root had positive correlation with the concentration of isoimperatorin in root.
CONCLUSIONFrom late April, A. dahurica var. formosana from Sichuan province entered root peak growth period and the accumulation of N, P, K, imperatorin and isoimperatorin in root increased rapidly. So the balanced application of fertilizer should be considered.

OBJECTIVETo study the effects of nitrogen (N), phosphorus (P2O5), potassium (K2O) and organic compound fertilizer (OF) on spicas biomass and yield of Prunella vulgaris in order to provide a theoretical basis for good agriculture practice (GAP).
METHODField plot experiments with a 4-variable quadratic orthogonal rotation combination design were adopted, and a function model of spicas yield in P. vulgaris was established.
RESULTThe model analysis showed that spicas yields of P. vulgaris were significantly influenced under the N, P2O5 and K2O applications, among there factors, N had the greatest effects on spicas yield of P. vulgaris, the next was P2O5 and K2O, OF had the smallest effects on spicas yield. At the lower fertility levels, the spicas yields of P. vulgaris were improved along with the increasing of N, P2O5, K2O and OF applications, but the spicas yields decreased when N, P2O5, K2O and OF were applied too much.
CONCLUSIONIn this experiment condition, the spicas yields of P. vulgaris could reach to 722 kg x hm(-2) when the fertilizer rates were N 303. 9-335.1 kg x hm(-2), P2O5 432.5-500.6 kg x hm(-2), K2O 206.6-240.2 kg x hm(-2), OF 2 312.5-2 687.5 kg x hm(-2).

OBJECTIVETo explore chemical component changes of dog bone at different lengthening time and in different bone regions of interest, and to evaluate the mineralization during Ilizarov lengthening process.
METHODSThe ash weight, the concentrations of calcium, phosphorus and the calcium/phosphorus ratio were measured at different intervals (2, 4, 6, 8, 12 weeks) since lengthening and the lengthened part was compared with a control area at each interval.
RESULTSThe ash weight, the concentrations of calcium and phosphorus in the lengthened area differed at all development time. The calcium/phosphorus (Ca/P) ratio in the lengthened region remained significantly lower than that in the control region up to 12 weeks after the lengthening.
CONCLUSIONSThese results suggest that also other inorganic ions play an important role in the mineralization process and that they become relatively more important since 8 weeks after the lengthening.

OBJECTIVETo study the changes of nutrient contents in Chinese goldthread soil before and after planting Coptis chinensis.
METHODThe soil in Shizhu, Chongqing, was analyzed for nutrient contents.
RESULT AND CONCLUSIONThe results indicated that the preplanted soil was strongly acidic and the levels of organic matter, total nitrogen and potassium were high. However, the content of total phosphorus was very low; so were the contents of other eleven nutrients. Variations of nutrients except zinc and molybdenum were large. After four years of planting C. chinensis, the soil pH was increased. Contents of organic matters, manganese, zinc and boron were increased, while the contents of iron and copper were decreased. In general, the variance coefficient of all nutrient elements and the difference of soil fertility were decreased.
