暗管排水是改造渍害低产田,提高农业单产的一个有效途径。在渍害低产田改造过程中,如何选择管材,如何制作暗管以及对不同类型的渍害田选用何种管材较为合适等,是当前各地渍改工作中普遍存在的问题。对此,本文拟就蕲春县经6年的摸索试验所取得的一些比较成功的经验作一简单介绍。 Hidden duct drainage is an effective way to transform low-yielding fields and improve agricultural yields. In the transformation of low-yielding fields, how to choose the pipe, how to make the pipe and how to select the different types of pipe are more appropriate, which are the common problems in the current stain-correcting work. In this regard, this article intends to make a brief introduction of some of the more successful experiences gained through six years of trial and error experiments in Hunchun County.
