在稻麦轮作中磷、钾和有机肥合理分配的计算机模拟单英杰，钟杭，朱顺富（浙江省农业厅土肥站）磷、钾、有机肥对麦子、早稻、晚稻产量影响的程度不一样，晚稻要重施钾肥，磷肥对春花作物效果好等，但对于磷、钾、有机肥在不同作物上合理分配的定量研究较少。有限的肥料在... Computer Simulation of Reasonable Allocation of Phosphorus, Potassium and Organic Fertilizer in Rice and Wheat Rotations Shannon, ZHONG Hang, ZHU Shun-fu Phosphate, potassium and organic fertilizers have different effects on the yield of wheat, early rice and late rice. Late rice should be re-applied potash, P fertilizer on the Chunhua crop effect is good, but for phosphorus, potassium, organic fertilizer in different crops rationally allocated quantitative research less. Limited fertilizer in ...
