摘要:

为解决过度施用化肥带来的面源污染问题,开展了缓释肥减量施用试验,调查了春优527在不同减量施肥条件下的产量及其经济效益。结果显示,在农户习惯施肥量的基础上,施用缓释肥减少10%~25%养分的情况下,水稻产量未受影响,10%减量处理的经济效益还稍高于农户常规施肥处理。在水稻生产中施用缓释肥料具有节本增效、降低污染的效果。

Abstract:

In order to solve the problem of surface-source pollution caused by excessive application of chemical fertilizer , the experiment of slow release fertilizer application was carried out in this paper, the yield and economic benefits of rice under different fertilization levels were investigated. The results showed that, compared with conventional fertilization, the yields of the treatments with reduction of 10% and 25% nutrients were not affected, and the economic benefit of the treatment with reduction of 10% nutrients was slightly higher than that of conventional fertilization, which indicated that the application of slow-release fertilizer could save cost, increase efficiency and reduce the risk of pollution.

Key words: rice, slow release fertilizer, reduced fertilization, benefit
