摘要
以杂交水稻“红莲优6号”为材料,通过3种不同栽插密度及方式来构建不同的群体结构,研究群体结构对水稻产量和品质的影响。结果表明:适宜密度(2.7×105穴/hm2)和栽插方式(宽行窄株)有利于杂交水稻组合“红莲优6号”产量和稻米品质的提高。密度和栽插方式主要影响群体叶面积指数、植株个体光合速率和群体内部光环境,对品质的影响,主要是降低稻米的垩白粒率和垩白度。
By using three different transplanting densities and modes different canopy structures were formed so as to study the influence of canopy structure on yield and quality of hybrid rice ＂Honglianyou 6＂. The results showed that appropriate transplanting density（2.7 ×10^5 hole/hm^2） and mode （wide row spacing and narrow hole spacing ） could increase the yield and improve the quality of the hybrid rice ＂Honglianyou 6＂. Appropriate density and mode could improve the light environment and raise net photosynthesis rate. It affected rice quality by reducing the chalky grain rate and chalky area of rice.
