Cultivation of natural cup-shaped crown: after transplanting the annual grafted seedlings, leave the trunk 1 m _, cut off the top, cut off the mouth buds and leave strong buds. Keep pulling out new branches below 1 m, and you can choose to be the main branch. Keep the same level and the same direction, so as not to cross each other and affect the tree shape and ventilation.

Cultivation of natural happy crown: after transplanting the annual grafted seedlings, the stems should be fixed at 40- 60 cm. In a plastic belt with a fixed stem height, three main branches are generally selected and all other branches are cut off. When cutting in the winter of the following year, cut the main branches 30-50 cm shorter. Other branches should also be removed.

Step 2 plant

The plant spacing is 4m×5m or 3m×4m, and 500-840 plants are planted per hectare. The planting period can be from defoliation to germination. Taoyuan cannot be continuously cropped.

Step 3 apply fertilizer

The demand ratio of peach for nitrogen, phosphorus and potassium is 1 ∶ 0.5 ∶ 1. Young trees control the amount of nitrogen fertilizer application, and increase the amount of nitrogen fertilizer application after the full fruit stage. The content of potassium in peach fruit is 3.2 times that of nitrogen. If potassium fertilizer is applied, the fruit will be bigger and the yield will be higher.

Results The tree was fertilized three times a year: in June, basal fertilizer 10- 1 1 was applied, mainly organic fertilizer; Strong fruit fertilizer was applied during the fruit hard-core period from late April to May, and potassium fertilizer was mainly applied to early-maturing seeds. The nitrogen content of middle and late-maturing seeds was 15%-20%, phosphorus was 20%-30%, and potassium was 40%. Fruit picking fertilizer is applied before and after fruit picking, accounting for 15%-20% of the whole year. In addition, the peach garden should be cultivated regularly to weed, keep the soil loose, and drain water in time to prevent stagnant water from rotting roots.

4. Plastic surgery

The height of the stem is about 60 cm, leaving 3-4 main branches at an angle of 50-60. Each main branch has 1-2 auxiliary branches, and few branchlets. Pruning period includes winter pruning and summer pruning.

5, pest control

Diseases include peach bacterial perforation, peach scab, peach brown rot, peach anthracnose, peach gummosis, root cancer and so on.

Pests include Myzus persicae, Tetranychus viennensis, Myzus persicae, Myzus persicae, stinkbug tea wing, scale insects, Myzus persicae and Cerambycidae.
