不同种植方式对玉米生长发育及产量的影响

Effect of Different Planting Methods on Growth and Yield of Maize

通过对玉米5种不同种植方式的对比试验,结果表明:种植方式不同,玉米的产量、果穗性状、植株性状、根系分布范围和数量、叶面积大小和保绿期等不同。玉米实行宽窄行双行单株错位定向移植,保证了玉米沿着最佳的生物学轨道生长发育,比其它几种移栽方式和直播增产显著,产量达620.9kg/667m2,比玉米单行大窝直播(对照)增产59.3%。

The results from a comparison experiment with five treatments of planting methods for maize, show that the different planting methods affect the yields, ear and plant characters, distribution range and quantity of root system and leaf area variously. Of five planting methods, the cultivation of directive setting single seedling in doublerow style of widenarrow space intercropping ensured the best growth of maize plants along biological regularity. The yield of this planting method is up to 9313.5kg/ha, increasing by 59.29% compared with those of the other planting methods. 
