【摘要】 夏玉米免耕播种科学的施肥方式是农民普遍关注的问题。通过５ 种不同施肥方式在施肥量、管理等相同的条件下，与不施肥为对照进行的对比试验，分析了不同处理植株体内叶绿素含量、植株形态构成、产量及形成产量相关因素，证明玉米免耕播种时合理使用种肥是极为重要的。在不同施肥方式的对比试验中，不等距间施种肥方式最优，玉米增产幅度最高。更多还原

【Abstract】 The scientific fertilization pattern for maize zero tillage seeding has received more and more attentions from farmers. Comparative experiments between no fertilization and five patterns of fertilization under conditions of the same fertilizer rate and the same management were conducted in this paper. Chlorophyll content in the plant, configuration of the plant, yield and factors related to the yield were analyzed. The results showed that it is very important to fertilize when seeding maize, and the unequivalent distance fertilization pattern, in which high yield of maize can be obtained,is the best way for corn zero tillage seeding.更多还原
