| Abstract: | Nitrogen(N) is the largest amount of application fertilizer in crop production.Overuse of N-fertilizer is a serious problem in rice production in China.Here reviewed the effects of N application techniques on grain yield and N use efficiency as well as their biological basis,and put forward some suggestions about how to realize higher grain yield and higher N use efficiency in rice. |
