小麦冬前生长过旺,容易受冻害,一定要注意控制麦苗冬前旺长,具体方法有6种:1、深锄断根。麦苗因肥水充足、温度高而生长过旺、茎叶过嫩的,采取深锄断根的办法加以控制是比较有效的,一般在主茎长到5叶期时,可用小齿耘锄在小麦行间深锄6~9cm。这样不但可以损失一些小麦的次生根,削弱它对养分和水分的吸收,抑制其地上部分的生长;同时,还能起到消灭杂草、疏松土壤、保墒防旱、提高地温、减
Wheat growth before winter too easily vulnerable to frost damage, we must pay attention to the control of winter wheat before long, there are 6 specific ways: 1, deep hoe off the root. Wheat seedlings due to adequate fertilizers, high temperature and overgrowth growth, too tender stems and leaves, take deep hoe off the root method to control is more effective, usually in the main stem to 5 leaf stage, can be used in small wheat hoe hoe line Deep hoe 6 ~ 9cm. This will not only lose some secondary roots of wheat, weaken its absorption of nutrients and water, inhibit the growth of the aboveground; the same time, it can play to eliminate weeds, soil loosening, moisture Prevent drought, increase ground temperature, reduce
