Scientifically matched with male plants, ≥150 male plants per hectare. 4. Fertilization: After planting the live tree, chase 1 to 2 times of quick-acting nitrogen fertilizer, generally 666.7m2 (mu) each time with diluted and decomposed human feces 5 to 6 dan. From June to August, organic fertilizer and potash are mainly used, and 2 to 3 times of flower and fruit fertilizer are applied again. Generally, 50 kg of cake fertilizer is used for 666 and 7 m2 or 1000 kg of decomposed human and animal feces plus 25 kg of potassium sulfate, 20 cm away from the root. Open the ring or radial shallow ditch and then pour the soil to prevent root damage. 5.
