不同种植密度条件下东北春玉米区主栽品种的适应性分析
Adaptability Analysis on Maize in Northern of Different Planting Densities
摘要
Abstract
Zhengdan958,Nonghua101 ,Xianyu335,Liaodan565,Danyu39 of Maize in Northern were used as experimental materials,and four planting densities (3 000,4 000,5 000,6 000 /667m2 )were set,explore the effects of different planting densities on the grain yield,LAI and drymatter accumulation.The results show that:The LAI increased with the increase in planting density,and it reached a peak at silking stage,and then began to reduce.As the planting density increased,the yield of each species was positively correlated with the basic,single plant dry matter weight of each organ were negatively correlated.With the increase of planting density,grain yield significantly increased,indicating that these species in the northern,there is potential for high density increase can be tapped.This provides a theoretical basis and technical support for corn yields in northern.关键词
