| 摘 要： | 以郑单958为试验材料,采用裂裂区设计,分别在75 000,90 000,105 000株·hm-23个种植密度下,研究了密度与种植方式对夏玉米郑单958叶绿素、荧光及其产量的影响。结果表明,展开叶叶面积指数,穗位叶叶绿素含量均随着密度的增加呈现单峰曲线变化的趋势。在密度一定的条件下,种植方式的改变,增加了光能的利用效率;高密度条件下,宽窄行双株种植改善群体结构,明显增加光合作用面积,提高群体光能利用率,有效增加高密度下玉米产量的潜力。

| Abstract: | To investigate the effects of the density and planting patterns on chlorophyll ,fluorescence and yield of summer maize Zhengdan 958 ,a field experiment was carried out with different plant population densities (7 .5 × 104 , 9 .0 × 104 ,1 .05 × 104 plants·hm - 2 ) using a split-split plot design .The results showed that with the increase of planting density ,LAI of extended leaves and chlorophyll content of ear leaf displayed a single peak variation curve .Under certain density ,changes in planting pattern could increase the use efficiency of light energy .Under high density condition ,the method of double strains cultivation with wide-narrow row spacing improved population structure ,significantly increased photosynthetic area ,enhanced group light energy utilization ,advancing the production potential of corn under high densi-ty . |
