不同时期施用分蘖肥对水稻产量及其结构的影响

为了验证水稻“三控”施肥技术在江西的应用效果，我们于2012～2013年研究了不同时期施用分蘖肥对水稻产量及产量结构的影响。结果表明：在栽足基本苗的条件下，应用“三控”施肥技术，分蘖肥于早稻栽后13d、晚稻栽后11-14d施用的增产及调控产量结构的效果最好。...

In order to verify the applied effect of ＂Three controls＂ fertilization technology in rice production of Jiangxi, we studied the effects of applying tillering fertilizer at different times on the yield and yield components of rice from 2012 to 2013. The results showed that： under the condition of transplanting sufficient basic rice seedlings, applying tillering fertilizer on the 13th day after transplanting early rice, or from the 11 th day to the 14th day after transplanting late rice could obtain
