Nitrogen Use Efficiency of Rice Breeding High Yield and Quality Basic Research and Its Application
Abstract：The research progress in the breeding of rice variety with high-efficiency nitrogen-using was summarized in this paper.The relationship between the activity of rice root system and the rate of N absorption was described.The difference in the nitrogen uptake of rice variety in different growth stages,the activity of nitrate reductase in different growth stages based on different levels of nitrogen application and other relevant issues were researched.Thus,the high yield,multiply panicle,high rate of seed-setting and high harvesting index could be used as the main reference indicators in this kind of new variety breeding.
