摘要
[目的]提高制种产量和质量,加快皖稻153品种的推广。[方法]设置每穴栽1、2、3、4苗4个处理,调查各处理的分蘖动态、农艺性状及发芽率。[结果]每穴多苗栽插可以提高有效穗,增加穗粒数,乃至提高制种产量。[结论]综合考虑各种因素,皖稻153的适宜制种栽插密度为2苗/穴。
[Objective] The study aimed to improve the yield and quality of hybrid seed production and promote the popularization of Wandao No. 153. [Method]Four treatments with planting density of 1, 2, 3, 4 scedling/holl were set up, and tillering dynamics,agrieuhure characters and germination rate were investigated. [Result ] effective panicle, grain number per spike and seed production were obviously increased under multiple seedlings planting in one boll. [Conclusion] Considering all kinds of factors synthetically, the optimum planting density of Wandao No.153 for seed production was 2 scedling/holl.
