适时浇好小麦越冬水,能促进根系发育,塌实土壤,粉碎坷垃,平抑地温的变化,对小麦盘墩扎根安全越冬极为有利。浇好越冬水还可以杀死越冬害虫,减轻为害。同时结合冬灌,可因苗施肥,并能促进有机肥料的分解和无机肥料的溶解,便于根系的吸收利用。盐碱地浇冬水还有压碱改土的作用。因此,冬灌具有明显的增产作用,一般可增产10～20%。除多雨年份,土壤湿度较大以外,一般越冬水为必浇之水。
Timely pouring wheat winter water, can promote root development, soil collapse, crushing Ke rub, to stabilize the changes in temperature, the winter wheat piers piercing the safe and win very favorable. Pouring more winter water can also kill overwintering pests, reduce damage. At the same time with winter irrigation, fertilizer can be used for the seedlings, and can promote the decomposition of organic fertilizer and inorganic fertilizer dissolved, easy to root absorption and utilization. Salt and alkali water to pouring wintering also Alkali soil improvement effect. Therefore, winter irrigation has a significant yield-increasing effect, can generally increase 10 to 20%. In addition to rainy years, the soil humidity is larger, the general overwintering water will be poured water.
