以徐稻4号为材料,对大田不同茎蘖基本苗、不同栽培方法进行实验.结果表明:单株带蘖比不带蘖增产14.17%、18.95%和22.15%,其最高产量为698.96 kg/666.7 m2.并对其穗粒结构进行分析.只有培育带蘖壮秧,提高秧苗素质,促进个体、群体协调发展,茎蘖消长、叶面积系数变化更加合理,才能实现更高产的目标.
Taking Xuyao 4 as the material, the basic seedlings and different cultivation methods of different tillers in the field were tested.The results showed that the maximum yield of the tiller with single tillers was 14.17%, 18.95% and 22.15% with no tillers, and the highest yield was 698.96 kg / 666.7 m2, and analyze their ear grain structure.It is only possible to achieve higher yield by cultivating strong seedlings with tillers, improving the quality of seedlings, promoting the coordinated development of individuals and groups, increasing and decreasing stem and tiller, and changing leaf area coefficient.
