[目的]为了研究不同氮肥、磷肥、钾肥配比施肥对晚稻欣荣优华占的产量及产量构成因素的影响。[方法]以晚稻欣荣优华占为试材,采用“3414”肥料设计,通过田间试验和室内分析开展研究。[结果]不同N、P、K肥施肥水平对欣荣优华占产量有显著的调节作用。在促进水稻晚稻品种欣荣优华占生长发育的N、P、K三种营养元素中,增产效果最为明显的是N肥。但是,随着N肥施用量的增加,当超过一定水平时水稻产量反而下降,其中处理瑏瑡(N3P2K2)的水稻产量比处理6(N2P2K2)低。P、K肥对水稻产量的影响也表现出相同的趋势。[结论]处理6(N2P2K2)既能满足水稻对肥料的需求,又能保证其正常生长,从而有利于实现水稻产量增产。
[Objective] The purpose was to study the effects of fertilizers with different N, P and K fertilizers on the yield and yield components of late rice Yanrong Youhua. [Method] With Latex Yan Xin You Hua as the tested material, using “3414” fertilizer design, through field experiments and laboratory analysis. [Result] The fertilization levels of different N, P, K fertilizers had a significant effect on the yield of Yanrong Youhua. Among the three nutrients N, P and K which promoted the growth and development of late rice varieties Yanrongyouhua, the most obvious increase was N fertilizer. However, with the increase of N fertilizer application, the yield of rice decreased when a certain level was exceeded. The yield of rice treated with N3P2K2 was lower than that of treatment 6 (N2P2K2). The effects of P and K fertilizers on rice yield also showed the same trend. [Conclusion] Treatment 6 (N2P2K2) could not only meet the demand of fertilizers for rice, but also ensure the normal growth of rice, which is good for increasing yield of rice.
