玉米冠层结构对种植密度的响应
Response of Different Planting Densities to Corn Canopy Structure
摘要
Abstract
To study the response of different planting densities to corn canopy structure,the leaf area index(LAI), the angle of stem to leaf,the leaf orientation value(LOV)and the yield of the corn numbered Zhengdan 958 and Weike 702 in five different planting densities were determined. Highest yields were obtained under the 90 000 plants/hm2 planting the LAI increased with increase of planting density,the distribution proportion of LAI became the largest above 90 000 plants/hm2 three-ear leaves,on 75 000 plants/hm2 three-ear leaves and under 60 000 plants/hm2 three-ear leaves. The angle of stem to leaf decreased with the increasing of planting density,while the LOV in-creased with the increase of planting densities.关键词
