Abstract
Reasonable strategy of irrigation and fertilization has great influence on improving nitrogen utilization efficiency(NUE) and yield of rice.Based on the data from field experiments,this paper tried to find out the effect of different water and fertilizer management patterns on the nitrogen absorption and utilization of rice plants and nitrogen distributions in different parts of rice.The results showed that controlled irrigation significantly improve the nitrogen absorption of rice and promote the nitrogen accumulation of rice grain;Site-specific nutrient management(SSNM) can effectively control the nitrogen absorption in rice vegetative organ during the earlier growing stage and significantly improve the redistribution and reuse of nitrogen in the rice straw;Controlled irrigation combined with SSNM can significantly control ineffective tillering,decrease nitrogen content of rice straw and increase the nitrogen translocation of rice vegetative organ.Controlled irrigation combined with SSNM can decrease the water and nitrogen amount and improve water and fertilizer use efficiency,so as to provide evidence for reasonable management of irrigation and fertilization in South China.
