我县盐碱地约3.5万亩,其中耕地3万亩,类型主要为硫酸盐氯化物,属轻度盐化草甸土,且大部在海拔千米以上的较冷凉地区。这类土壤是农业生产的主要障碍,一是春季风多雨少,土壤升温快,蒸发量大,盐基离子聚积地表,危害作物幼苗,保 About 30,000 acres of saline land in our county, of which 30,000 acres of arable land, the type of sulfate chloride, is a mild saline meadow soil, and most of the more than 1000 meters above sea level in more cold areas. This type of soil is the major obstacle to agricultural production. The first is that the spring monsoon is less rainy, the soil temperature is faster, the amount of evaporation is large, the surface of salt-based ions accumulates, and the crop seedlings are harmed.
