| 摘 要： | 试验分析了5种免耕播种夏玉米施肥方式对植株体内叶绿素含量、植株形态构成、产量及其形成相关因素的影响。结果表明，不等距间施肥方式效果最好，叶绿素含量达3.94mg/g，不同时期叶面积均最高，有利于全苗壮苗，增强抗旱能力，夏玉米产量最高达7646.3kg/hm2，增产幅度为35.23%。

| Abstract: | The rational fertilization to summer maize under zero-tillage cultivation has been paid more and more attentions by farmers.Comparative experiments between no fertilization and five ways of fertilization under conditions of same fertilizer-rate and same management were conducted.Result showed that the unequivalent distance fertilization method was the best way for summer maize under zero-tillage.Under this condition,chlorophyll content was 3.94mg/g,leaf area was the largest and grain yield reached 7646.3kg/hm2,increased by35.23%. |
