在春季施肥时,如果单独施用化肥或有机肥或生物菌肥,都不能使蔬菜长时间保持良好的生长状态,这是因为每种肥料都有各自的短处:化肥养分集中,施入后见效快,但是长期大量施用会造成土壤板结、盐渍化等问题;有机肥养分全,可促进土壤团粒结构的形成,培肥土壤,但养分含量少,释放慢,到了蔬菜生长后期不能供应足够的养分;生物菌肥可活化土壤中被固定的 Fertilizers or organic fertilizers or biofertilizers alone can not keep the vegetables in good condition for a long time when fertilizing in the spring because each fertilizer has its own drawbacks: concentration of nutrients in the fertilizer, rapid response after application , But long-term large-scale application will lead to soil compaction, salinization and other issues; organic fertilizer nutrients, can promote the formation of soil aggregate structure, fertilize the soil, but less nutrient content, slow release, late vegetable growth can not supply enough nutrients Bio-bacteria fertilizers can be activated in the soil to be immobilized
