摘要
[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 the theoretical basis for the application and the popularization of new fertilizer. [ Meth- od] The field tial was carried out to study the effects of P, K compound fertilizer on the growth and the yield of paddy rice. [ Result] Meisheng series of P, K compound fertilizer had control effects on the stem and the tiller of the paddy rice, reduced the plant height, inhibited the invalid stem and tiller, improved the group structure of high yied paddy flee, increased the effective spike number, and prevented the stem lodging. [ Conclusion] The coordinate application of MESZ and Kmag had the obvious effects on the yield of the paddy rice.
