不同控释尿素配比对节水抗旱稻肥效影响研究
Fertilizer effects of different ratio of controlled-release urea on water saving and drought resistance rice
摘要
Abstract
Fertilizer effects of different ratio of controlled-release urea and urea on the yield and nitrogen u-tilization rate of water saving and drought resistance rice ‘Hanyou 8’were studied under field condition in Shanghai suburbs.The results showed that compared with the same amount N of urea treatment,the rice yield of controlled-release urea(CRU)+ urea(U)treatment increased obviously.And the treatment of 40%U +60%CRU +topdressing could improve the rice yield about 5%.Compared with the same amount N of urea treatment, the treatment of CRU +U could improve the utilization rate of N fertilizer,reduce the amount of N fertilizer,and the N fertilizer utilization rate was more significant.In the treatments of different CRU +U,the treatment of 50%CRU +50% U improved the rice yield most obviously.关键词
