[0016] A method for delaying the degradation of acidified soil in an apple orchard, comprising the steps of:
[0017] 1) Select fertilizer: select bio-organic fertilizer and inorganic fertilizer compound fertilizer I, compound fertilizer II and medium and trace element fertilizer. 2 o 5 +K 2 O≥6%, the compound fertilizer I index is N:P 2 o 5 :K 2 O=1:1:1, the index of compound fertilizer II is N:P 2 o 5 :K 2 O=1:0.5:1;
[0018] 2) Application of bio-organic fertilizer: After the apples are harvested (apple yield per mu is 3500kg / mu), the pH value of the soil is detected to be 4.2, and the amount of bio-organic fertilizer is 10kg / plant. Shaped ditch, covered with soil after fertilization;
[0019] 3) Planting sage grass: sow sage grass in September, the sowing rate is 1.5kg / mu, the sowing method of sage grass is drill, the row spacing is 40cm, and the sage grass seeds and fine sand are mixed in a weight ratio of 1:10;
[0020] 4) Applying inorganic fertilizers: in mid...
