“水稻制种宝”在C两优华占制种上的应用效果研究

Study on the Application Effect of “the Treasure of Seed Production” on the Seed Production of C Liangyou Hua Zhan

摘要: 杂交水稻的制种是一个受多方面因素影响的过程，环境因素直接影响着水稻生产的芽率、结实率、产量等。本文探讨了“水稻制种宝”不同的施用量对C两优华占有效穗、结实率、产量以及相对经济产出的影响，结果表明：1) 基施“水稻制种宝”能有效的增加单位面积有效穗，在试验浓度范围内，随着施用量的增加而增加；2) 基施“水稻制种宝”在一定程度上能提高制种结实率与产量，达到增产增收的目的，其中A₄处理结实率最高，A₃处理产量最高；3) 基施“水稻制种宝”能提高相对经济产出，以A₃处理的相对经济产出最高，增幅达5.28%。

Abstract: The process of hybrid rice seed production was affected by many factors. The environmental factors directly affected the bud rate, seed setting rate, the yield of rice, etc. This paper investigated the application rate of “the treasure of seed production” on the effect of the effective panicle number and seed setting rate and yield and the relative of economic output. The results showed that: 1) Basal application could increase spikes in unit area, according to the test concentration, spikes in unit area were increased with the increasing of the application rate. 2) To some extent, “the treasure of seed production” increased the seed setting rate and yield in seed propagation with basal application, and the highest seed setting rate was the treatment of A₄, the yield of A₃ was the highest. 3) With basal application, “the treasure of seed production” could increase by 5.28% on the relative of economic output, and the treatment of A₃ was the highest.
