水氮互作对水稻群体结构的影响

Effects of Water-nitrogen Interaction on Rice Group Structure

水稻的分蘖数、株高、每株叶面积受氮肥影响较大,均随施氮量的提高而提高,分蘖、株高受灌溉条件的影响不明显。总体上来说,增施氮肥可以改善水稻的群体生长质量,但过高的氮肥并不表现为更利于水稻的生长。

The tillers,plant height,per plant leaf area,each part of plant of the rice are influenced by nitrogen fertilizer obviously,and raise by the increase of nitrogen rate,but irrigation condition has little influence on tillers and plant height.Conclusively,nitrogen increasing tend can improve the group growth quality.However,too much nitrogen is not beneficial to the growth of rice.
