We must grasp the good times. In the early stage of fruit tree growth, the base fertilizer should be applied. Long-lasting, high-content boron can be used. Bearing boron is an imported soil-based fertilization with an effective boron content of 15% and a long-lasting effect of 3 to 6 months. It is easy to use and low in cost. The perennial orchard has an application rate of 400 to 600 grams per mu and costs about 6-13 yuan. About one month after the Spring Festival, it is applied to the soil before the early spring germination. According to the size of the fruit trees, the application of strips or acupoints, such as compound fertilizer, is better. In the middle and late growth stages, it is necessary to supplement the quick-acting fertilizer. Generally, when the fruit trees are swollen and the fruit is swollen, the quick-acting boron fertilizer is sprayed, such as Suile Boron, 50 g per acre, 1000 times of water is applied; the zinc fertilizer can be used for Hefeng zinc. The dosage per acre is 15 grams, and the water can be sprayed 3000 times.
