Planting techniques of American Big Cherry

American big cherry, the fruit is thick, the color is deep red and bright, the taste is sweet, many people like to eat, how can we grow American big cherry in our country? Let's take a brief look at the planting techniques of big cherries in the United States.

The main results are as follows: 1. The acidity and alkalinity of the soil in the planting garden should be kept neutral, the soil layer is thick, loose and fertile sandy soil.

2. American cherry is generally cultivated in the form of grafting. The suitable grafting periods are late March, late June and September, and the methods of ventral grafting with single bud at the top, T-shaped bud grafting and xylem bud grafting (embedded bud grafting) can be used.

3. Dwarfing and dense planting was adopted. Proper deep planting should make the original root neck about 15cm lower than the ground, but when burying the soil, it should be buried shallowly, with each hoe, gradually burying the soil, and before the rainy season in July, the buried soil will be flush with the ground, so that part of the rootstock can take root, expand the absorption area and enhance the lodging resistance of the tree. Be careful not to bury too much soil at one time, otherwise the root system will have difficulty in breathing and affect the growth of the tree.

4. 1-2 years after seedling planting, fertilizer and water should be applied frequently to promote the rapid growth of trees. After entering the high-yield period, apply more organic fertilizer and less chemical fertilizer.

5. Prune the branches of fruit trees reasonably. There are many big branches of young trees, and the big branches that need to be removed should be gradually removed year by year. The big cherry branch is easy to split, and the branch with small angle is not suitable to be the main branch. Therefore, those with small angles should be removed as soon as possible.

6. The configuration of pollination tree can be decided according to the actual size of the park. When the seedlings of main varieties and pollinated varieties are half and half of each other, determinant planting can be adopted. When there are few seedlings of pollination tree varieties, distributed or central pollination trees can be used.

7. During the period of fruit expansion, it is necessary to combine watering and apply potassium sulfate compound fertilizer and pure potassium fertilizer to promote fruit expansion.

8. Pay attention to the management of tree potential after fruit harvest, reasonable branch thinning, balanced fertilization, increase the application amount of organic fertilizer and bacterial fertilizer, and strengthen the storage of boron and calcium in trees.

9. When managing orchards, pay attention to diseases, pests and birds. Big cherry pests are relatively mild, spraying 3-4 times a year; diseases can be combined with pests; build a bird net before the fruit yellowing, and remove it after fruit picking.

The above is only a brief description of the planting steps of American cherry, and the specific implementation methods still need to consult the relevant people.
