摘　　要：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.Different tiller seedlings and different cultivation methods of Xudao No. 4 were tested and the structures of ears and grains were analyzed. The results showed that the yield of a single plant with tillers was 14. 17%, 18. 95% and 22. 15% higher than that of single plant without tillers respectively. The highest yield is 698.96 kg/666.7 m^2. Higher yield will be achieved only by culturing strong seedling with tillers, improving seedling quality, coordinating colony development, tiller growth and decline and the change leaf area coefficient could be more rational to realize the higher yield.
