Effects of Different Type and Amount of Slow-release Nitrogen Fertilizer on Yield and Economic Benefit of Japonica Rice in South China
张鸿燕1,陈燕2*,刘宇新1,周利军2 . 缓控释氮肥种类和用量对南方粳稻产量和收益的影响[J]. 中国稻米, 2016 , 22(5) : 35 -37 . DOI: 10.3969/j.issn.1006-8082.2016.05.008
In order to define the reasonable type and amounts of slow-release nitrogen fertilizer on japonica rice in Southern hillside area, the authors analysised the yield and fertilizer use efficency of two kinds of slow-release nitrogen fertilizer with different coating materials(resin coated urea and water-soluble polymer coated urea), and assessed the inputs and benefits of different treatments, taking common urea as control. The results showed that slow-release fertilizer significantly increased rice yield, agronomic efficiency and economic benefit, compared with common urea. The water soluble polymer coated urea is a better kind of slow-release fertilizer in Southern hillside area, and the best application amount was 195 kg/hm2.
