我盟是旱作农业,目前有70%以上的中低产地。今后应通过正确合理的耕作管理措施,扭转土壤肥力下降的趋势,并不断有所提高和恢复,把每年400毫米左右的降水在土壤中保存起来,加上增施有机肥,使耕地逐渐形成“土壤肥水库”。同时还要施行一套科学的耕作栽培措施。主要抓好以下几点:1.农田建设。大多数中低产地,主要分布在旱坡上,水土流失严重,每年冲走大量的土和肥,是造成土壤贫瘠和干旱减产的一个直接原因。如
Our Union is a dry farming and there are currently over 70% of low and middle producing areas. In the future, through correct and reasonable tillage management measures, we should reverse the trend of decline in soil fertility and continue to improve and restore precipitation at a rate of about 400 millimeters per year in the soil. Adding organic fertilizers will gradually increase the cultivated land to “ Soil Fertility Reservoir. ” At the same time also implement a set of scientific cultivation and cultivation measures. Mainly to do the following: 1 farmland construction. Most low and middle producing areas are mainly distributed on dry slopes with serious soil erosion. Each year, large amounts of soil and fertilizer are washed away, which is a direct cause of soil fertility and drought reduction. Such as
