Abstract:

In order to study the effects of application of Lvxianji and Lvjuneng compound fertilizers on rice yield and benefit, we made comparison research on dynamics of tillers, panicle traits, yield and yield components of rice. The results showed that, compared with Lvjuneng compound fertilizer, Lvxianji compound fertilizer improved the effective tiller percentage, increased the number of primary and secondary branches, reduced the branch degeneration rate, and finally improved rice yield. In addition, Lvxianji compound fertilizer made more profit because of higher yield and lower cost.

Key words: rice, compound fertilizer, yield, economic benefit

摘要：

为探讨绿先机、绿聚能复合肥对水稻产量及效益的影响，笔者特设置了此试验，对水稻茎蘖动态、穗部性状、产量及产量构成等进行了测定和比较分析。结果表明，绿先机复合肥提高了水稻的分蘖成穗率；增加了一次枝梗数和二次枝梗数，减少了枝梗退化率；对水稻单位面积穗数、每穗粒数和结实率均有促进作用，进而提高了水稻产量；绿先机复合肥成本较低，可进一步增加水稻的生产效益。
