半夏种植密度及底肥施用水平的研究

Study on Cultivation Density and Utilization Level of Base Fertilizer of Pinellia ternata

目的 探索和掌握半夏种植中的最佳施肥水平和密度 ,为生产提供优良、经济的方法。方法 设计进行了 2个因素各 3个水平的正交实验。结果 当地半夏栽培选用 4 kg/m2施肥量和 B3=0 .35 kg/m2的种植密度有较高的产量 ,在经济上也较实用可行。结论 较适合的下种量为 0 .35 kg/m2 ,以药渣为有机底肥的施用量为 4 kg/m2 。

Objective Optimum fertilizer applying level and the thickness in the growing of Pinellia ternata are probed,so as to offer superior and economical means for manufacture. Methods Three lever two element orthogonal experimental design has been carried out. Result The growing thickness of B 3=0.35 kg/m 2 and fertilizer applying amount of 4 kg/m 2 can lead to comparatively high yield and is economically feasible as well. Conclusion The optimum cultivation density is 0.35 kg/m 2,and the applying amount of base fertilizer is 4 kg/m 2.
