1, planting: the height of the fixed pole is 60 ~ 70 cm, which can promote 3 ~ 5 main branches.

2. Pruning and shaping trees in winter: China cherry mostly adopts multi-branch cluster. Pick new shoots at 30cm from June to July to promote secondary branching, keep the balance of main branches and increase the amount of branches. In the future, measures such as pulling branches, twisting branches, cutting short branches and adjusting fruiting branches can be taken year by year according to the tree shape.

3. Pruning the fruiting tree in winter: after the cherry enters the fruiting period, it is necessary to maintain the tree shape to improve the fruiting ability, and its annual development branches should not be cut short except those that are too vigorous. Prune and clean up dead branches, twigs, pests and diseases, and clean up the orchard in time.

4. Pruning after harvest: Pruning the redundant miscellaneous branches to promote the growth of new shoots of fruit trees. Thinning after fruit picking is mainly to adjust the tree structure, improve the ventilation and light transmission conditions inside the crown, promote flower bud differentiation and later growth and development, and balance the tree potential. Pruning methods mainly include drying and pruning: strong branches that seriously affect ventilation and light transmission inside the crown and have no retention value can be dried from the base.

5. Pruning in rainy season: The new shoots grow vigorously in rainy season, so it is necessary to pick the core in time to ensure the ventilation and light transmission of the trees, and at the same time remove the tall weeds in the garden.

Second, fertilizer and water management.

1, apply autumn fertilizer in winter, and apply base fertilizer from September to before defoliation.

Apply appropriate pre-flowering fertilizer in February and March.

Apply 1 ~ 2 times potassium fertilizer in time in March and April, and cover the bird net in time before the fruit ripens.

4, high temperature and rainy season, need to do a good job of irrigation and drainage in time, and timely and appropriate topdressing, so as to avoid premature aging of trees.

Extended data:

Pest control:

1, clear the garden after pruning in winter, and spray sulfur stone mixture to prevent overwintering eggs and germs.

2, March weed removal, comprehensive spraying broad-spectrum pesticides and fungicides, pay attention to aphids and perforation after spreading leaves, timely protection.

3. Pay attention to the protection of leaves after harvest, and give priority to prevention and comprehensive prevention of possible pests and diseases in each season.
