摘要
2010年在辽宁省中部地区水稻上开展一次性底施缓释尿素田间试验。结果表明:在辽宁中部地区水稻上一次性施用缓释尿素比施用普通尿素,增产效果非常明显,开原和大石桥试验点增产31.1～57.0kg/667m2,增产率为5.9%～10.9%;辽中试验点增产34.7～88.9kg/667m2,增产率为10.1%～21.3%。
A field experiment was conducted on the one shot bottom application of controlled-release urea in rice in the middle pat of Liaoning province in 2010.The results show that there is a dramatic increase in yields after one shot bottom application of controlledrelease urea in rice in the middle pat of Liaoning province compared with application of common urea.The increase in yields in Kaiyuan and Dashiqiao is 31.1～57.0 kg /667 m2,or at a rate of 5.9%～10.9%;that in Liaozhong is 34.7～88.9 kg /667 m2,or at a rate of 10.1%～ 21.3%.
