碳酸盐草甸土质地粘糗紧实，通透性能差，土壤养分释放能力低，田间持水量低，不耐涝，又不抗旱，是制约粮食产量不稳定的原因之一。近几年来，我县对碳酸盐草甸土进行一系列的改良，根据它的土质粘糗，土壤呈弱碱性等特点，结合本地的实际，采取如下措施： 1超深松改土排涝 　 Carbonate meadow soil clay sticky tight, poor permeability, low soil nutrient release capacity, low water holding capacity, not resistant to waterlogging, nor drought, is one of the reasons restricting the instability of grain yield. In recent years, a series of improvements have been made to carbonate meadow soil in our county. According to its characteristics such as clay stickiness and weakly alkaline soil, combined with the local practice, the following measures were taken:
