摘要(Abstract):

目的 :根据主产区高产丹参和低产丹参药材产量的差异性 ,研究非地带紫色土区的丹参土壤发生学特征值分子比率的特性。方法 :在四川中江紫色丘陵生态区 ,选择发育在同一母质k1cy的高产丹参和低产丹参 ,测产采用样方测定法 ,以风干品计算产量 ;土壤黏粒胶体元素含量测定方法有重量法、KF取代EDTA容量法、邻菲啉比色法、二胺替比林甲烷比色法、中和滴定法。变量差异性分析采用t检验法。结果 :高产丹参和低产丹参的药材产量差异极显著 (P <0 .0 0 1) ,高产型土壤的发生学特征高于低产型土壤。结论 :紫色土发生学特征值是丹参生药产量及规格品质的重要土宜因素之一 ,土壤风化程度深浅与丹参产量密切相关。
Objective: To study the characteristics of the SiO 2/R 2O 3 in non-zonal purple soil in the light of the difference between the high yield and low yield of Salvia miltiorrhiza. Method: Both the high yield and low yield drugs developed from the same parental material (k 1cy) were chosen in the ecology area in Zhongjiang county ,Sichuan Province. By using the air-dried drugs as sample, quadrat sampling method was used to calculat the production. Gravimetric method, volumetric method, and colorimetric method and neutralization titration were used to measure the content of adhesive particle colloids element in the soil. And T-test was used for the variable-difference analysis. Result: There was a sharp contrast between the production of high yield and low yield drugs (P<0.001).The characteristic value of the high yield soil embryology was much higher than that of the low yield soil. Conclusion: The characteristic value of the purple soil embryology is one of the important factors of the soil adaptability of the drug and its quality. The weathering degree of the soil is closely related to the yield of the drug.
