【摘要】 通过对黎榆 A 繁殖田母本不同栽插密度和不同基本苗数的结果分析:表明穗实粒数、结实率以母本株行距13.2 cm×13.2 cm,2苗/穴栽插最高。不同栽插基本苗之间产量差异极显著,不同栽插密度之间、不同栽插基本苗数×不同栽插密度之间产量差异不显著;黎榆 A 繁殖母本栽插以株行距13.2 cm×13.2 cm,2苗/穴栽插最佳。
【Abstract】 The relationship of planting density(PD),seedling per hill(SPH)and multiphcation yield of Liyu A was studied .The results showed that could product higher yield with the highest number for filled grains per panicle、seed- set rate under the female planting pattern of a spacing of 13.2 cm×13.2 cm.by two SPH.The SPH effected multiplication yield of Liyu A significantly,neither do PD and SPH/PD.
【Key words】 multiplication of Liyu A; seedlings per hill; planting density; multiplication yield;
