针对当地栗钙土坡梁地旱、薄的作物生产障碍，根据土壤水分时空变异和层位特征，充分利用有限的降水资源，采用聚水土沟作、聚水沟作等保护性耕作措施，较传统耕作莜麦产量提高１８．４％～２３．４％，水分利用效率由４．０５ｋｇ／ｍｍ·ｈｍ２提高到４．５７～４．６４ｋｇ／ｍｍ·ｈｍ２；而改变土壤营养环境则显著提高水分作物生产力。在贫水、平水和丰水三种降水年型下，氮磷肥合理配施莅麦产量可提高８９．８％～１６１．２％，水分利用效率可高达７．２７ｋｇ／ｍｍ·ｈｍ２。
According to the dry and thin crop production obstacles of the local chestnut soil slope, according to the temporal and spatial variations of soil moisture and horizon characteristics, it makes full use of the limited precipitation resources, using polygamy and gully for conservation tillage The yield of traditional cultivation of oatmeal increased by 18.4% ~ 23.4%, and the water use efficiency increased from 4.05kg / mm · hm2 to 4.57 ~ 4.64kg / mm · hm2. However, changing the soil nutrient environment significantly increased the water content Crop productivity. Under the three types of rainfall, such as lean water, flat water and abundant water, the yield of nitrogen and phosphorus could be increased by 89.8% ~ 161.2% and the water use efficiency could reach as high as 7.27kg / mm · hm2.
