Autumn is the harvest season, when seasonal fruits continue to appear on the market, persimmons are also ripe at this time, ripe persimmons soft and sweet, very delicious. At the time of harvest, fruit farmers are also mixed, happy is about to harvest, worried about the problem of sweet persimmon fruit drop, persimmon fruit drop attention is their own physiological causes and diseases and insect pests, no matter what kind of reasons will cause serious economic losses to fruit farmers. So is there any way to reduce the fruit drop rate of persimmon? Come and have a look with the editor.

1. Variety selection

There are great differences among persimmon varieties. Some plants do not need pollination, such as the big mill, which can bear fruit directly and are not easy to fall due to poor pollination, while others must be equipped with pollination trees, especially the varieties caused by Japan. Poor pollination is the root cause of a large number of fruit drop, so in order to reduce the fruit drop rate, we must first understand the varieties of our own persimmon trees.

2. Flower branch treatment

Including branch pruning, ring peeling and bud thinning, in order to avoid waste of fertilizer and water and poor permeability in the later stage, invalid branches and overgrown branches must be trimmed before flowering, following the principle of more branches on the windward side and less branches on the leeward side, so as to ensure ventilation and avoid the growth and spread of germs. Girdling can not only promote flower bud differentiation, but also bear fruit in advance and reduce physiological fruit drop. Girdling is generally carried out in the early flowering stage. After girdling, plastic strips should be used to maintain peeling humidity, promote healing, and strengthen fertilizer and water management. Thinning and pruning flower buds in order to ensure the final fruit quality, generally retain the first 2-3 fruiting branches on the fruiting mother branch, each fruiting branch leaves 3 buds in the middle, and the rest are all thinned.

3. Fertilizer and water management

When applying sufficient basal fertilizer in spring and autumn, topdressing should not be premature, generally in May branch withering period and July fruit expansion period. These two times of topdressing can obviously promote the fruit setting rate and increase the number and quality of flower buds in the next year. Foliar topdressing was carried out in the middle and later stage of the result, and the mixture of foliar fertilizer and Yimi yield-increasing bacteria was sprayed every other month to spray all branches, leaves and fruits evenly, and it was best to start dripping.

4. Pest prevention and control

The peak period of larval occurrence is in May, July and August every year, and the pest is mainly persimmon stem worm, which is divided into two infections, which can easily lead to fruit shedding; the disease is mainly anthracnose, which is usually pink in the late growth stage, causing fruit drop. Therefore, in the young fruit stage, couples should timely spray 800x persimmon disease gram water solution, or 50% Sukeling wettable powder 1000 times solution, in the fruit ripening period continuously spray 800-1500 times Jiaojie water solution, or 1000 times speed water solution to prevent and cure.
