超级晚稻丰源优299的产量与氮利用效率优势初探
Preliminary Study on Advantages of Super Late Rice Combination Fengyuanyou 299in Yield and Nitrogen Utilization Efficiency
摘要
Abstract
To study the advantages of super late rice combination Fengyuanyou 299 in yield and nitrogen utilization efficiency, a field plot experiment was conducted with two-line hybrid rice combination C Liangyou 4488 and three-line hybrid rice combination Weiyou 46 as control. The results showed that Fengyuanyou 299 had more significant yield superiority. At the same time, nitrogen accumulation, nitrogen use efficiency, nitrogen uptake efficiency, nitrogen harvest ■ index, nitrogen fertilizer efficiency and nitrogen utilization efficiency of Fengyuanyou 299 were significantly higher than those of common hybrid rice. So application of super hybrid rice in production can not only increase yield of food but also heighten nitrogen utilization efficiency and reduce the environment pollution induced by nitrogen loss.关键词
