| Abstract: | 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%. |
