直播水稻施用缓释放肥料效果研究

The effect of slow-release fertilizer on direct-seed rice

为了研究缓释放肥料在直播水稻上的使用效果,对单季晚稻品种"秀水123"进行了田间试验。试验结果表明:与普通化肥相比,使用缓释放肥料具有明显的增产作用(增产率3%～6%),肥料的利用率明显提高(提高4～5个百分点),明显提高了水稻生产的经济效益(增219.0～327.9元人民币/hm^2);使用缓释放肥料具有控肥、增产、增效的综合效益。

Field experiments with single-crop late-maturing rice variety ＂Xiushui 123＂ were carried out in order to study the effect of slow-release fertilizer on direct-seed rice. The experimental results showed that compared with conventional chemical fertilizer application, application of slow-release fertilizer could significantly increase the rice yield by 3 % - 6%, the utilization rate of fertilizer by 4 - 5 percentage points and the economic benefit by 219.0- 327.9 yuan/hm^2.
