A Detailed Explanation of the Causes of Fruit Drop During the Cherry Ripening Period and the Control Methods

Cherries are currently one of the premium fruits on the market, with high market demand and high prices, so the number of people growing them is gradually increasing, and the phenomenon of fruit drop during the cherry ripening period is also becoming more and more serious. There are mainly two causes of fruit drop during the cherry ripening period: one is physiological fruit drop, and the other is non-physiological fruit drop. Let's take a look below, together with the editor, at each of the causes and the control methods.

I. Physiological fruit drop

The cause of physiological fruit drop in cherries is mainly a deficiency of trace elements. The solutions are as follows:

1. Supplement trace elements. You can spray the plants with foliar fertilizer containing trace elements by means of foliar feeding, for example fulvic acid salt Ruilv or Jinhuibao, etc., for foliar spraying, which can noticeably reduce the phenomenon of cherry fruit drop.

2. Apply more biological fertilizer. In addition to conventional fertilization, you also need to pay attention to applying more biological fertilizer. It can promote the growth of the plant's root system, ensure that the roots absorb all kinds of nutrients evenly, and slow down the phenomenon of fruit drop.

3. Root irrigation. In addition to foliar spraying, you can also use Jinhuibao, Lvlishen, Haili, Jiaqiaofeng, and Qianglizhuanggenji for root irrigation to promote root growth and slow down fruit drop.

II. Non-physiological fruit drop

1. Causes

There are relatively many causes of non-physiological fruit drop. First, a single cultivated variety or an improper arrangement of pollinator trees causes severe flower and fruit drop; second, insufficient tree nutrition, with no sufficient nutrient supply to support fruit growth, so the fruit naturally falls off; third, unreasonable temperature and humidity control. If the temperature is too high before or after flowering, it will damage the floral organs and aggravate physiological fruit drop. If the humidity of the floral organs is too high, it will also cause pollen to absorb water and become sticky, leading to pollination difficulties; fourth, extensive management, which causes severe pests and diseases and aggravates flower and fruit drop.

2. Control methods

Pollination arrangements with the same flowering period should be set up. The ratio of the main cultivated variety to the pollinator variety is best at 3:1 or 2:1. In this way, even when the weather during the flowering period is poor, they can still pollinate each other. During the fruit's hard-core stage, strengthen fertilizer and water management to ensure the supply of nutrients and water and effectively reduce fruit drop. On the basis of applying more base fertilizer, topdress in time during the process of fruit growth and development. You can spray a mixed solution of low-concentration urea and potassium dihydrogen phosphate to meet the fruit's nutrient needs.
