How to manage cherries before they blossom and mature?

The flower and fruit management of cherry is mainly reflected in pollination and fruit protection, fruit thinning and fruit protection before harvest. Cherry is a fruit tree with low self-flowering and fruiting ability. in order to ensure fruit, in addition to configuring pollination trees during the establishment of the garden, artificial pollination and auxiliary pollination by flower-visiting insects should be done to improve the fruit setting rate. At the same time, 0.3% urea + 0.3% borax or 0.5% potassium dihydrogen phosphate solution was sprayed every 10 days to increase the fruit setting rate. Thinning buds is to pick the weak and stunted buds between blossoms. Bud thinning can improve the nutrient supply of reserved flowers, which is an effective measure to increase the single fruit weight of cherry, which is generally carried out from late March to late April, and each bouquet-shaped short fruit branch has about 2-3 buds. By thinning buds, the fruit can be increased. Fruit thinning is a production technology to further improve the size of fruit on the basis of bud thinning. It is usually carried out after the physiological fruit drop in the middle and last ten days of May. Each bouquet-shaped short fruit branch has 3 or 4 fruits. Through fruit thinning, the load of the plant can be further adjusted, the fruit can be increased, and the sugar content of the fruit can be increased. Sparse fruit should pay attention to the small fruit and light is not easy to shine, poor coloring of drooping fruit thinning, retain horizontal and upward large fruit. Techniques to promote coloring include leaf removal and the use of reflective films. The fruit on the short fruit branch is easy to be blocked by clustered leaves. In order to promote the coloring of the fruit, the leaves that cover the sunlight of the fruit should be removed at the beginning of coloring, and a silver reflective plastic film should be laid under the crown to make use of the reflected light under the crown to promote fruit coloring. In order to avoid the occurrence of fruit cracking, rain-proof tents are generally set up in early June, the initial period of fruit coloring, and the effect is very good. In addition, when the fruit is ripe, birds often feed, so we should pay attention to preventing birds and usually take the method of casting a net to protect the tree.
