三麦是江苏主要粮食作物之一,种植面积占耕地面积的58％,总产约占全年粮食总产的1/3。由于渍害普遍存在,准南、苏南地区尤为严重,已成为当前三麦高产稳产的主要障碍,本文分析了渍害的成因。比较了麦田排水中明沟与暗沟的作用,着重论述了鼠道排水降低地下水位、排除土壤积水、有利于三麦生长发育等方面效能。介绍了鼠道田的合理布局、鼠道出口控制方法、鼠道的施工工具。由于鼠道属于机械施工,工效高、成本低,能达到一次打洞,稻麦两利,多年使用,是一种廉价的行之有效的地下排水措施,目前在江苏省已推广20万亩。
Sanmai is one of the major grain crops in Jiangsu Province, with acreage accounting for 58% of the cultivated area and total output accounting for about 1/3 of the total grain output of the year. Due to the prevalence of waterlogging, especially in the south and south of Jiangsu Province, it has become the main obstacle to the high yield and stable yield of the three wheat cultivars at present. This paper analyzes the causes of waterlogging. Compared the effect of open ditches and underdrain ditches in wheat field drainage, the article discusses emphatically the effect of rat drainage to reduce groundwater level, remove soil water, and promote the growth and development of three wheat. The reasonable layout of rat lane, the control method of rat exit and the construction tools of mouse lane are introduced. As the rat is a mechanical construction, high efficiency, low cost, to achieve a hole, rice and wheat Lee, for many years, is a cheap and effective underground drainage measures, is currently in Jiangsu Province to promote 20 million mu.
