| 摘 要： | 氮肥运筹对小麦茎秆节间长度、茎秆充实度和茎秆氮残留量有明显的影响，从而影响了小麦的倒伏．施氮187.5kg／hm^2的处理与拔节后施肥的处理，倒伏率较低，产量最高．控制施氮量。确定适宜的施肥时期，可以降低倒伏率，提高产量．本还对其他防倒措施进行了探讨．

| Abstract: | The length and the substantiality between the nodes of wheat stem and the quantity of nitrogen left in wheat stem are obviously influenced by nitrogen application, so is the lodging of wheat. The results show that the lodging is not serious and the yield per hectare is the highest of all under the treatments of nitrogen fertilizing at 187. 5 kg/hm2 level and after jointing stage. The lodging rate may decrease and the yield per unit area may increase if nitrogen is fertilized in proper quantity and at proper stage. Other methods of preventing lodging are also discussed here. |
