| 摘 要： | 根据水氮耦合试验,小麦单产随着施氮水平和浇水次数的增加而提高,当施氮肥量达到337.5 kg/hm2时,小麦产量最高,以后随着施氮量的增加,单产下降.一水产量是5 092.5 kg/hm2,二水产量比一水提高14.6%,三水产量比一水提高了10.5%.小麦子粒中蛋白质含量随施氮量的增加而略有下降;随着浇水次数的增加,蛋白质含量也下降.

| Abstract: | The experiment in combining application of water and nitrogen was conducted in Huanghuaihai plain and the result indicated that the wheat yield was increased with the amount of nitrogen and irrigation raising.When the amount of nitrogen reached 337.5 kg/hm2,the highest wheat yield was 6 790.5 kg/hm2.Then the amount of nitrogen reached 450 kg/hm2,the wheat yield was decreased with 6 457.5 kg/hm2.When the wheat was irrigated once,the wheat yield was 5 092.5 kg/hm2;and 14.6% and 10.5% of wheat yield were increased,respectively,under two times and three times irrigations.The content of wheat protein was dropped with the amount of nitrogen and irrigation increasing. |
