1．穗粒肥的生产效应①能保持棍的活力调节叶色变化；②能增加穗的枝梗数和平均着粒数；③能促进植株正常出穗和如期成熟，并可使迟发蘖加速生长进而增加稔实穗的数量，④能生产出粒厚大千粒重也大，熟期早产量也高的稻谷。当然，过量施用穗粒肥（尤其是氮肥）确实能很高包括醇 1. Spike fertilizer production effect ① can maintain the vitality of the stick to regulate leaf color change; ② can increase the number of branches and the panicle average grain number; ③ can promote plant normal ear emergence and maturity, and delayed tiller can accelerate growth and thus increase稔 real spike number, ④ can produce a thick grain weight is also large, early maturity of rice is also high.
