Answer: There are two reasons why the peach fruit is too small. The first is that the fruit is overheated or too cold during the pollination period, and the pollination is poor. The second is malnutrition, such as zinc deficiency and zinc deficiency can lead to fruit dysplasia. In the expansion period, the peach trees need to be fertile, and the fruit farmers should also implement underground supplementary nutrition in time, and apply quick-acting compound fertilizers for nitrogen, phosphorus and potassium fruit trees, mainly potassium. In the fruit-bearing period, 20 kg of special fertilizer for fruit trees with a potassium content of 100 kg should be applied. At the same time, the appropriate amount of roots should be applied at the same time. The top dressing should be pure nutrient-free and full-nutrient foliar fertilizer without hormones.
