在以硫酸盐、氯化物为主的内蒙古河套平原盐渍化中度和重度盐碱地种植星星草等耐盐牧草,上年秋季深翻熟化土壤,当年春季再耕翻播种结合灌水,星星草等出苗率达60%以上,保苗率达90%,能正常返青完成生育期,每公顷产鲜草15000公斤,土壤盐分和pH值逐年下降,养分含量提高。种植四年之后,0~15厘米表土层含盐量普遍降低70%左右,是一种行之有效的生物改良盐荒地的措施
In the sulfate and chloride-dominated Inner Mongolia, Inner Mongolia, Hetao plain salinization moderate and severe saline-alkali grass and other weeds planted salt grass, the autumn of last year, deep maturing soil, then the spring tillage seed combination with irrigation, Aster grass emergence The rate of 60% or more, seedling protection rate of 90%, can return to normal completion of the green growth period, yield of 15,000 kg per hectare of fresh grass, soil salt and pH decreased year by year, nutrient content increased. After four years of planting, the salinity of 0-15 cm topsoil generally reduces about 70%, which is an effective measure to improve salt wasteland
