王文丽1,姜彩霞2,王一斐3,周江明4*,王晓东4 . 缓释肥减量施用对春优927产量及经济效益的影响[J]. 中国稻米, 2019 , 25(1) : 97 -99 . DOI: 10.3969/j.issn.1006-8082.2019.01.023
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
