摘要： 试验结果表明,玉米地膜覆盖下包体施肥与空白、条沟追肥、穴窝追肥比较,株高、穗位均降低,节间缩短、茎秆增粗,群体稳定性增强,叶面积加大,叶片持绿期、功能期延长;穗粒数增加到616.33粒。千粒重达到340.0g,比空白、条沟追肥、穴窝追肥增重19.5,15.0,5.0g,分别增产7.33%,5.37%,4.08%。包体施肥能够有效替代地膜覆盖玉米的中、后期追肥。

Abstract: Multiple functional filmed manure-Body under plastic film mulch in maize are applied (once for all).It's more convenient,saving powers and fertilizer.Also,it can make high and stable yield.According to the trial,compared with no fertilizer application (NFA),strip fertilizer application (SFA),hole fertilizer application (HFA) in growth period of maize,filmed manure-body fertilization had many merits:Both plant height and ear location were decreased,distance between two neighbouring nodes were shortened,stems were thickened,colony stability was strengthened,leave area was enlarged,leave lasting green stage and function stage were prolonged.The number of ear kernel increased to 616.33,1000-grain weight was up to 340.0 g,compared with NFA,SFA,HFA,1000 grain weight increased 19.5,15.0,5.0 g,yield increased 7.33%,5.37%,4.08%.Filmed manure body fertilization can effectively go instead of the medium late stage fertilizing of plastic film mulch in maize.

Key words: Maize, Plastic film mulch, Multiple functional filmed manure body
