小麦灌浆期要充分满足籽粒灌浆的环境条件,延长灌浆时间,增强灌浆强度,才能提高粒重,获得高产。一、中期控肥控制麦田中期氮肥追施量,有利于提高植株体内碳氮比,促进营养生长向生殖生长的转移,提早抽穗期,延长灌浆时间。二、重视后期浇水浇水不仅可以降低地温,防止干热风危害,还能达到以水养根,以根保叶,以叶保粒重的目的。浇灌桨水时间以抽穗后10~15天为宜;水量不宜大;对保水差的沙壤土,浇水10天后再补浇一次麦黄水,增粒重效果更好。由于麦田后期植株高,密度大,底节长,鲜重高,要坚持“小水勤浇,风大停浇,无风抢浇,昼夜轮浇”的方法,以免造成倒伏。
Wheat filling period to fully meet the environmental conditions of grain filling, grain filling time to extend and enhance grouting strength, in order to improve grain weight, high yield. First, the medium-term control of fertilizer in the mid-term control of nitrogen fertilizer topdressing amount of wheat is conducive to improving plant carbon and nitrogen ratio, to promote the transfer of vegetative growth to reproductive growth, early heading, to extend the filling time. Second, pay attention to the latter part of the watering can not only reduce the ground temperature to prevent the hazards of dry and hot winds, but also to reach the root of water to protect the leaves, leaves Paul grain weight purposes. Irrigation paddling time to heading 10 to 15 days is appropriate; the amount of water should not be large; poor water retention of sandy loam, water 10 days after pouring a wheat bran water, grain weight better. As the latter part of the wheat plant height, density, long bottom section, fresh weight high, we must adhere to “small water pouring, the wind stop pouring, no wind grab pouring, pouring day and night” approach to avoid lodging.
