缓控释肥对水稻的应用效应研究

试验以高产水稻品种阳光200为试验材料，采用小区试验结合大田对比示范，研究了缓控释肥与配方肥、普通化肥对水稻产量、产量构成性状以及经济效益的影响。结果表明，与施用配方肥、普通化肥相比，施用缓控释肥对水稻有一定的增产效应，分蘖成穗率比配方肥增加1.5个百分点，比习惯施肥增加4.6个百分点。由于缓控释肥市场时价较高，尚未表现出节本优势。

Application Effect of Slow and Controlled Release Fertilizer on Rice

With the high-yield rice cultivar Yangguang 200 as material,the effects of slow and controlled release fertilizer,fomulated fertilizer and common fertilizer on rice yield,yield components and economical benefit were studied by plot experiment combined with field test.The results showed that the application of slow and controlled fertilizer could increase the rice yield compared with the fomulated fertilizer and common fertilizer.The effective spike rate of tiller of the treatment with slow and controlled fertilizer was 1.5 and 4.6 percentage points respectively more than that of the treatments with fomulated fertilizer and common fertilizer respectively.The price of the slow and controlled fertilizer is higher,so it has not showed saving cost.
