当前，蔬菜种植面积迅速扩大，新菜田大多是粮田，其土壤板结、有机质含量低、矿质营养不足、土壤熟化差，新建温室地块，由于取土打墙，有机质馈乏，按常规菜田施肥方法，远远不能满足蔬菜作物对土壤营养及透气性的要求，所以粮田改菜田定要多施优质有机肥，促进土壤熟化，提? At present, the planting area of ​​vegetables is rapidly expanding. Most of the new vegetable fields are grain fields. Their soil compaction, organic matter content is low, mineral nutrition is poor, and soil ripening is poor.
