[目的]为新型肥料的应用与推广提供理论依据。[方法]通过田间试验,研究不同磷钾复合肥对水稻生长和产量的影响。[结果]美盛系列磷钾肥对水稻茎蘖有一定的控制作用,可降低株高,抑制水稻无效茎蘖的发生,改善水稻高产群体结构,提高水稻的有效穗数量,防止倒伏。[结论]MESZ和Kmag配合施用对水稻有显著增产效果。
[Objective] The research aimed to provide a theoretical basis for the application and popularization of new fertilizers. [Method] The effects of different phosphorus and potassium compound fertilizers on the growth and yield of rice were studied through field experiments. [Result] Meishan P and K had certain control effects on the tillering of rice, which could reduce the plant height, inhibit the occurrence of inefficient tillers, improve the population structure of high yielding rice, increase the effective panicles of rice and prevent the lodging. [Conclusion] The combined application of MESZ and Kmag had significant yield increase effect on rice.
