微生物菌肥对贵州黔东南连作太子参产量的影响

Effect of Microbial Fertilizer on Yield of Cropping Pseudostellaria heterophylla in Southeast of Guizhou Province

[目的]研究微生物菌肥对贵州黔东南连作太子参产量的影响。[方法]采用L9(34)正交试验法,在黔东南州施秉县牛大场镇和黄平县一碗水乡选点进行太子参规范化种植;利用微生物菌肥对土壤进行调节,了解微生物菌肥种类、施用量及施用方式对连作地太子参的产量影响。[结果]因素的主次影响顺序皆为C>B>A,即菌肥的使用方法对产量的影响效果比较大,较所用菌肥的种类和施用量都更明显。[结论]试验研究了微生物菌肥对贵州黔东南连作太子参产量的影响,为太子参的进一步开发利用提供了依据。

[ Objective ] To study effect of microbial fertilizer on yield of cropping Pseudostellaria heterophylla in southeast of Guizhou Prov-ince. [ Method] By using L9 （34） orthogonal test, standardization planting of P. heterophylla was conducted in Niudachang Town and Yiwan- shui Village; Soil was treated by microbial fertilizer, effects of microbial fertilizer species, application amount and fertilization way on yield of cropping P. heterophylla were studied. [ Result] The order of influencing factors are C 〉 B 〉 A, namely the effect of utilization way is more significant that species and application amount of fertilizer. [ Conclusion] The study will provide a reference for the further development and u-tilization of P. heterophylla.
