What about persimmon falling flowers and fruits?

When persimmon is planted, because it is extremely harsh to the growth environment, once because of improper management, it is very easy to fall flowers and fruits, which seriously affects the yield of persimmon. So what should we do about persimmon falling flowers and fruits? Let's take a look at the detailed introduction with the editor.

1. Rational fertilization

The topdressing of persimmon should not be premature, generally in the withered top period of branches in May and the fruit expansion period in July. Topdressing can increase yield obviously through the fruit setting rate of persimmon trees in these two periods. In addition, it can also promote the number of flower bud differentiation in the following year, and effectively prevent the phenomenon of falling flowers and fruits through the quality of flower buds.

2. Girdling at flowering stage

In the flowering stage, girdling can not only reduce the rate of fruit setting, but also effectively prevent the drop of flowers and fruits. In the early flowering stage of persimmon, cut two rings about 0.5cm apart with a knife at 30-50cm from the trunk to the ground, reaching the depth of xylem and peeling off the bark in the ring. In this way, the girdling is completed. in order to prevent germs from invading the harmful plants from the wound, it is necessary to do a good job in the yield of the wound and bind the wound with plastic sheet. in addition, it should be noted that the weak branches of weak trees are not suitable for girdling.

3. Thinning flowers and fruits

One of the reasons for falling flowers and fruits is that there are too many blossoms and fruits, and the nutrients needed for their growth exceed the supply of plants, so they will fall off due to lack of nutrients, affecting the quality of other fruits. Therefore, it is necessary to wipe buds, pick hearts and thinning flowers and fruits in time, specifically as follows: timely removal of branches and buds that sprout too densely, timely pick hearts of overgrown branches that grow to more than 20cm, and timely thinning of plants or branches with a large number of flowering and fruiting. This can reduce the burden of the plant, concentrate more nutrients on part of the fruit, and promote its growth.

4. strengthen the prevention and control of diseases and insect pests

A large part of the reason for flower and fruit drop is caused by diseases and insect pests, such as persimmon round spot, persimmon stem worm and persimmon scale. It is necessary to strengthen the control of them, spraying Baumedushi sulfur mixture in May and Bordeaux liquid in June, which has a better control effect on them.

5. Spraying medicine

Spraying a low concentration of boric acid and ammonium molybdate water mixture solution at full flowering stage can significantly increase the fruit setting rate and reduce the probability of flower drop, while gibberellin solution can be sprayed in the young fruit stage.
