To solve the problem, re-inserting and continuous cropping can promote the release of phosphorus and potassium in soil and organic fertilizers and the mineralization of organic matter, making the soil loose, breathable, water-retaining and fertilizer-retaining. , providing a comfortable micro-ecological environment for crops. At the same time, beneficial bacteria proliferate rapidly and secrete large amounts of mucopolysaccharides and other crop biostimulating substances and lactic acid active factors and other microecological activating substances, providing a comfortable growth environment for the growth of crops and achieving the purpose of soil microecological improvement.
