吨田宝叶面肥在中稻上的使用效果

Applying Effect of Duntianbao Foliar Fertilizer on Growth and Grain Yield of Rice

[目的]为了验证吨田宝叶面肥对水稻生长的影响及其使用效果。[方法]采用水育移栽,调查、记载水稻各主要生育时期,记录各产量性状指标。[结果]吨田宝能增加有效穗数、总粒数和实粒数,但对结实率影响不大,增产幅度为5.01%~12.6%。[结论]吨田宝对水稻增产的作用机理有待进一步研究。

[ Objective] The research aimed to validate the effects of applying Duntianbao foliar fertilizer on the growth and grain yield of flee. [ Method] Sterile water transplanting was conducted. Every main growth stages of the rice were investigated and recorded. Every indicators of yield trait were recorded. [ Result] Duntianbao foliar-fertilizer could increase the effective number, total number of grains per spike, kernel number, and improve 5.01% - 12.6%. [ Conclusion] Further study of action mechanism of Duntianbao foliar-fertilizer on the yield increase of rice should be carried out.
