| 摘 要： | 小麦在生育后期,旗叶逐渐衰老,生理功能降低,增施钾肥,可以提高旗叶chl和pro含量。减少(?)产生,降低MDA含量,起到延缓衰老,增强旗叶功能,从而增加单位面积上产量的作用,施用量在150kg/hm~2以内时,效果随施用量增加而逐渐增加,超过150kg/hm~2以后效果又开始逐渐下降。

| Abstract: | During the late growth period, flag leaf decrease the physiological function and grows old gradually. Application potasium fertilizer could increase chlorophgll and protein content of flag leaf,decrease the produce of O2 and MDA,retard the leaf growing old .stren-then the function of flag leaf ,thus increare the yielol. The effect is evident as the application amount increases wthen the amount is betow 150Kg/hm2, and the effect begin to decreasegradually when the amuunt is over 150Kg/hm2. |
