有机无机肥互作对玉米产量及耕层土壤特性的影响

以两个不同类型玉米科多4号和鲁单50为试验材料,通过不同有机肥无机肥互作的大田试验,研究了玉米产量和耕层土壤理化性质的变化。结果表明,鸡粪肥配施氮肥可以显著地提高玉米的生物产量和子粒产量,秸秆还田配施氮肥当年增产效果不显著,但能显著地改善耕层土壤的理化性质,两个杂交种对各处理的反应基本一致。

Influence of Organic Manure and Inorganic Manure Interaction on Yield of Maize and Characteristic of Topsoil

Two hybrids of maize KD4 and LD50 were used in this study.Under di fferent manure interaction conditions in field experiment, the effect of organic manure and inorganic manure interaction on yield of maize and topsoil was evalu ated. The results indicated that Fertilizing chook muck and nitrogen together can improve biological yield and grain yield of maize remarkably, returning straw to field and Fertilizing nitrogen can increase production result remarkably in t hat year, improve topsoil physics and chemistry nature of soil remarkably. Two h ybrids are unanimous basically to the response that is dealt with.
