对豫西旱农区两种轮作方式下旱地的耕作保墒技术进行了3年研究。着重讨论了二年三熟制下晒旱地深耕、深耕加秸秆覆盖以及深耕配施有机肥的蓄水保墒效果;一年二熟制下中耕效果与土壤质地和土壤含水量的关系以及中耕的适宜范围、多次中耕对保墒的迭加作用等问题,为完善旱农区的耕作保墒技术提供了科学依据。
A three-year study on tillage and soil moisture conservation technology in dryland under two types of cropping patterns in arid area of western Henan was carried out. The effects of deep plowing and deep plowing with straw mulching and deep plowing with organic manure on water storage and soil moisture conservation were mainly discussed in two years. The relationship between mid-plow effect and soil texture and soil water content under one-year cropping system and suitable tillage Range, multiple cropping on the role of superposition of soil moisture and other issues, to improve the arid farming area moisture conservation technology provides a scientific basis.
