不同施氮量对小豆生长发育、产量及效益的影响

Effects of Different Nitrogen Levels on Growth,Yield and Benefit of Adzuki Beans

[目的]确定小豆最适施氮量,为小豆配方施肥提供科学依据。[方法]以辽红小豆8号为供试品种,通过不同氮素水平对小豆生长发育及产量性状的影响,确定小豆的推荐施氮量。[结果]小豆最适施氮量为90~120 kg/hm^2。[结论]氮肥对小豆的生长发育以及产量影响明显,适当增加施氮量可以提高小豆产量。

[Objective] Determining the optimum amount of nitrogen adzuki beans, which could provide scientific basis for fertilization. [Method] The tested variety was No.8 Liaoning red bean. the effect of different nitrogen levels on growth and yield of adzuki bean were studied. And the recommended nitrogen was determined. [Results] Adzuki beans optimum amount of nitrogen was 90-120 kg/hm^2. [Conclusion] Nitrogen fertilizer had significant effect on the growth and yield of adzuki beans and appropriately increased the application amount of nitrogen fertilizer could improve the yield of Adzuki beans.
