[0020] The first step of preparation before seedling cultivation: 1) Preparation of cultivation substrate: Take corn stalks, wheat stalks, soybean stalks and peanut skins in equal parts by weight, pulverize them and incinerate them into ashes, add animal manure in equal parts, and adjust the water content to 35% , sealed with a plastic film, placed at a temperature of 40°C, turned over once every 3 days, so that the mixture is fully fermented and decomposed to obtain the required organic matrix;
[0021] 2) Select loamy soil with fertile soil, thick soil layer, good irrigation and drainage. Before the seedlings are planted, sprinkle the organic substrate obtained in 1) into the soil at a rate of 250 kg per mu, plow deeply and open a ditch with a distance of 60cm , the width of the ditch is 25cm, the depth is 20cm, the soil and fertilizer are mixed evenly, and the water is heavy;
