三江平原是我国有名的低湿平原,总面积1.6亿亩。大部分耕地低洼,土质粘重,微地形复杂,致使耕地雨后积水严重。 排除田块地表水,有效的传统方法是开挖密集临时排水沟(又称毛沟)。但由于需劳力多,沟道纵横,影响机械作业。为此,在三江平原临时沟排水的应用和效果受到局限。然而至今也还没有找到一种更能适应三江平原田块生产特点的排地表水方法。 而鼠遭排水以往总被人们认为,仅是排土壤重力水,治理哑巴涝的。而从有关资料和我们几年的实践证明鼠道不仅可排土壤重力水,还可排地表水。与临时沟排水比,鼠道排水主要是能适应三江平原农业生产特点。用鼠道犁打洞,形成地下一个“洞”, Sanjiang Plain is China’s famous low-humidity plain, with a total area of ​​160 million mu. Most of the arable land is low-lying, the soil is heavy and the micro-topography is complicated, resulting in severe water accumulation in the arable land. Excluding field surface water, the effective traditional method is to excavate dense temporary drainage (also known as furrows). However, due to the labor required, vertical and horizontal channels, affecting mechanical operations. For this reason, the application and effect of temporary ditch drainage in the Sanjiang Plain have been limited. However, up to now, no one has yet found a method of surface water drainage that can better adapt to the production characteristics of the plots in the Sanjiang Plain. In the past, mice were always drained of water that people only think of soil gravitropism as drainage and control dumb waterlogging. From the relevant information and our practice of several years have proved that the rat can not only drain soil gravity water, but also row of surface water. Compared with the temporary ditch drainage, rat drainage is mainly able to adapt to the characteristics of agricultural production in the Sanjiang Plain.
