摘要
软埝田是把培地埂与修软埝结合起来的一种梯田形式。采用推土机推、压筑埂与拖拉机耕翻相结合修筑软埝田,是机械施工治理旱塬缓坡地的一种新方法。这种工程形式和推犁结合的施工方法,我们从60年代开始试验,70年代示范推广,已在隰县修软埝田4.6万亩。实践证明,推犁结合修软埝田,具有工效高、速度快、质量好、省劳力、投资少、施工技术简单、易于推广等优点,而且修筑当年就可增产,颇受群众欢迎。
Soil ridge is a kind of terraced field on gentle slopes, in which constructing banks and building soil ridge are combined. The way of blading and flattening the land surface, and building ridges by bulldozer, ploughing by ploughshares ( moved by tractor ) has been adopted unanimously in Linfen Experimental Station of Soil and Water Conserva tibn Shanxi Province since 1960s'. Reverse ridges and fluctuating ridges with gradient of 1:10 are constructed. The method with which non-irrigated plateau fields on gentle slopes are harnessed is efficient, inexpensive,good for soil conservation and the out-put may be increased. The method has been popularized extensively in the local area. This paper presents the technology of using this method and analyses its technological economic benefits.
