(1) Although winter pruning can be carried out throughout the dormant period, for cherries, the later the better. Generally, pruning is most appropriate when the buds are about to sprout.

(2) The flower buds of sweet cherry are lateral pure flower buds, and the terminal buds are leaf buds. After the flower buds bloom and bear fruit, they form blind nodes and no longer germinate. When pruning fruiting branches, the cut buds should not be left on the flower buds, but should be left on 2 to 3 leaf buds above the flower bud segment.

(3) After the tree branches are injured, the wound healing ability of sweet cherries is poor. The wounds on the roots and branches are difficult to heal, and they are easily infected by bacteria, leading to gum flow or disease. Therefore, in terms of time management, Special care must be taken not to damage the tree body and branches, and try to avoid thinning out thick branches and roots; do a good job of wound protection, and girdling techniques should be used with caution on sweet cherry trees, because branches are prone to glue leakage and breakage after girdling.

(4) Sweet cherries like light and have strong polarity. If too many peripheral branches are shorted during pruning, it will lead to excessive peripheral branches, dense branches, strong tops and weak bottoms, and small inner branches. And as a result, the school group is prone to weakening and dying.

(5) Methods to control the vigorous growth of new shoots: First, spray compound plant growth hormone or paclobutrazol, usually before and after the flowering period in spring. The second is to pick the top in time. The new shoots at the top can be topping when they are 5 to 7 centimeters long, and only the tip is removed. Topping must be done on semi-lignified parts.

(6) Thinning buds and fruits. Sweet cherry bud thinning can be started one month before germination, usually from late February to late March, and completed before germination. Sweet cherry bud thinning generally requires about 50% of the total number to be thinned out. The specific bud thinning should be "thinning more on weak trees and less on strong trees". When thinning buds, you must not thin out the center buds, which are the leaf buds.

The fruit thinning period ends at the end of physiological fruit drop. 20 to 30 days after flowering, about 3 fruits will remain on each bunch-shaped short fruit branch. The fruits must be thinned out in May.

7 Pay attention to the fertilizer and water management of sweet cherries, as well as other comprehensive management.

We must pay attention to the application of organic fertilizers. The amount of fertilization in sweet cherry orchards should be determined according to local soil conditions and fertilization characteristics. Top dressing after flowering should be based on nitrogen fertilizer, and should be completed 10 to 20 days after flowering. The last fertilization should be completed 30 days before fruit picking.

The second is to pay attention to foliar spraying of fertilizers, combining underground application with tree spraying, and paying attention to the spraying of nitrogen fertilizers, boron fertilizers, zinc fertilizers, potassium fertilizers, and calcium fertilizers. Foliar spraying can be combined with spraying. The last foliar spraying should be completed 20 days before the fruit harvest period. Sweet cherry trees have the highest water requirements from April to May, especially May. To ensure that the soil is moist during this period, you can water lightly once every 7 to 10 days, and water frequently.

Third, we must pay special attention to fertilizer and water management in spring; in summer, we must do a good job in drainage and waterlogging prevention, orchard leaf protection, spray growth control agents on flourishing trees, and do not blindly fertilize to control vigorous growth; in autumn, we must do a good job in tree body Nutrient reserves; pay attention to tree protection in winter.

The fourth is to promote the technology of covering sorghum with straw, weeds, or growing grass.

Fifth, special attention should be paid to the climatic conditions during the flowering period. Sweet cherries do not like high temperatures, and if exposed to high temperatures during flower bud differentiation, they may easily form deformed fruits.
