有机肥可提高土壤有机质含量,改良土壤理化性质。能够增加土壤的通气性、透水性、蓄水性,改善根系生长环境,增强土壤的保水保肥能力。大量施用化学肥料或养分配比不当均会导致农产品品质下降,而有机肥和化肥配合施用,可提高作物的蛋白质、氨基酸的含量,同时也使蔬菜当中的硝酸盐含量下降,维生素C含量上升。植物体内氨基酸含量的增加,有助于植物的抗旱,从而增强植物抗逆性和抗病虫害的能力。为此,农民在购买有机肥
Organic fertilizer can increase soil organic matter content and improve soil physical and chemical properties. Can increase the permeability of the soil, water permeability, water storage, improve the root growth environment, and enhance soil water retention ability. Large quantities of chemical fertilizers or improper distribution of nutrients will lead to the decline of the quality of agricultural products. However, the application of organic manure and chemical fertilizers can increase the content of protein and amino acid in the crops, but also reduce the nitrate content in vegetables and the vitamin C content. Plant amino acid content increases, contribute to drought resistance of plants, thereby enhancing plant resilience and pest resistance. To this end, farmers are buying organic fertilizer
