本文对豫西旱农区两种轮作方式的旱地耕作保墒技术进行研究。结果表明，晒旱地深加麦秸覆盖对保蓄土壤水分最为有利，深耕与配施有机肥之间有正交互效应，故深耕、覆盖再配施有机肥的综合措施对小麦增产效果最为明显，但免耕晒旱并不适用于豫西丘陵区。中耕措施是调节土壤水分的主要手段，一般在雨后进行一次高质量的中耕即可达保墒目的．
In this paper, two kinds of cropland rotation moisture conservation techniques of dryland farming in arid area of western Henan were studied. The results showed that in the dry land, wheat straw coverage was the most favorable to the conservation of soil moisture, and there was an orthogonal interaction between deep plowing and organic manure application. Therefore, the comprehensive effects of deep plowing and organic manure application were the most obvious. No-till drought does not apply to the hilly area in western Henan. Cultivation measures is the main means of regulating soil moisture, generally after the rain a high-quality cultivation can reach the goal of soil moisture.
