Causes and Control methods of Fruit drop during ripening period of Cherry

Cherry is currently one of the most valuable fruits in the market, with high market demand and high price, so the number of growers is also growing, and the phenomenon of fruit drop during cherry ripening is becoming more and more serious. There are two main reasons for cherry fruit drop during ripening period, one is physiological fruit drop, and the other is non-physiological fruit drop. Let's take a look at the respective causes and control methods together with Xiaobian.

1. Physiological fruit drop

The physiological fruit drop of cherry is mainly caused by the lack of trace elements, and the solutions are as follows:

1. To supplement microelements, foliar fertilizer containing trace elements can be sprayed on the plant by spraying foliar fertilizer, such as fulvic acid salt Ruilu or gold return, which can obviously reduce the phenomenon of cherry fruit drop.

2. To increase the application of biological fertilizer, in addition to conventional fertilization, we should also pay attention to the application of biological fertilizer, which can promote the growth of plant roots, 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, can also be irrigated with Golden return, Green God, Haili, Chrysanthemum and strong root strengthening agents to promote root growth and slow down fruit drop.

Second, non-physiological fruit drop

1. Reason

There are many reasons for non-physiological fruit drop, one is that the cultivated variety is single or the pollination tree is improperly configured, resulting in serious flower and fruit drop, but because the tree body is not nutritious enough to supply fruit growth, the fruit will fall off naturally. Third, the control of temperature and humidity is unreasonable. If the temperature is too high before or after flowering, the flower organ will be damaged, the physiological fruit drop will be aggravated, and the humidity of the flower organ will be too high, which will also cause pollen water absorption and stickiness, resulting in pollination annoyance; fourth, extensive management will cause serious diseases and insect pests, aggravate the serious drop of flowers and fruits.

2. Prevention and control methods

In order to configure the pollination configuration with the same flowering period, the proportion of main varieties and pollinated varieties should be 3 ∶ 1 or 2 ∶ 1. In this way, in the case of poor climate at flowering stage, they can also pollinate each other. In the fruit hard kernel period, Britain should strengthen fertilizer and water management to ensure the supply of nutrients and water, and effectively reduce fruit drop. On the basis of increasing the application of base fertilizer, topdressing should be applied in time in the process of fruit growth and development, and the mixture of low concentration of urea and potassium dihydrogen phosphate can be sprayed to meet the nutrient demand of fruit.

The above is the cherry ripening period of the reasons and control methods, hope to help you, want to know more related knowledge, please pay attention to us.
