【摘要】 通过剪叶、包穗、包穗下节等处理,研究了不同氮肥施用量下小麦光合器官对千粒重、千粒重贡献率的影响。结果表明,施氮肥既影响叶器官也影响非叶器官对千粒重的效应,在叶器官或非叶器官功能不能正常发挥时,施用氮肥有利于千粒重及千粒重贡献率的提高。
【Abstract】 Through the treatments of defoliate,darken ear and darken peduncle,we studied the effects of wheat photosynthesis organs on the 1000-grain weight and the contribution to 1000-grain weight in different quantity of N.The results show that the nitrogenous influence the 1000-grain weight,which is brought by both leaf organs and no-leaf organs;nitrogenous fertilizer can improve the 1000-grain weight,the contribution rate of 1000-grain weight.
【Key words】 The quantity of N; Wheat; Photosynthesis organs; the 1000-grain weight;
