坡耕地综合治理技术模式的蓄水保土及增产效应
Effects of technology modes for sloping farm-land comprehensive control on soil water conservation and crop yield
摘要
Abstract
In order to resolve ecological problems such as soil erosion, spring drought and the waterlogging of topsoil in the northern hill black soil region of the Song-nen Plain, four comprehensive technology modes composed by four measures (furrow damming, mole drain, pipe drain and surface drain) were proposed. Taking the slop farmland (3') in Red Star Farm as the research object, a 2-year field experiment was conducted in 2009-2010 and the effects of different technology modes on dynamic variation of soil water, soybean yield, water use efficiency, surface runoff and soil erosion were studied. The results showed that four comprehensive modes had positive effects both on soil and water erosion control and water use efficiency increasing, among which the mode of SAMQ (the combination of mole drain, pipe drain, surface drain and furrow damming) was the best Compared with the conventional tillage, SAMQ increased the yield and water use efficiency by 27.3% and 23.9% respectively, and reduced surface runoff and soil erosion by 31.3 mm and 456 t/(km2a) respectively.关键词
