Potted apricot trees, pruning diligently, increasing germination rate and promoting flower opening.

Apricot potted plants should first select suitable varieties, and then carry out seedling cultivation and pot planting, when apricot trees grow to a certain period of time, they should carry out shaping and pruning in time, and then manage the fertilizer of basin soil and increase fertilizer timely according to the situation. in the later stage, we should also pay attention to the prevention and control of diseases and insect pests, so that apricot trees can grow healthily.

Apricot trees bear fruit early, with long life and strong adaptability, so they are more suitable for potted plants. Their apricot fruits are beautiful in color, beautiful in appearance and fragrant in smell. Potted apricots can be placed in houses, balconies and other places. Potted apricot trees are loved by many people.

I. Variety selection

Potted apricot trees should choose varieties with large fruit, bright color, long viewing period, late flowering and easy to avoid the harm of late frost. Lanzhou Dajie apricot, white plum apricot, string red apricot, Hebei Daxiang white apricot and crystal apricot are all good choices for potted apricot trees.

II. Seedling cultivation

Apricot seedlings are generally cultivated by grafting. Apricot seedlings can be purchased directly from the flower market, or rootstock seeds can be sowed directly in the nursery before the soil freezes in autumn, with a depth of about 7 cm. After sowing, the soil is covered with irrigation, and the seedling emergence rate can generally reach about 90% in the second spring. In the third year, excellent varieties can be selected for branch grafting, and the survival rate is very high. The methods of spring sowing, summer and autumn buds can also be used to raise seedlings.

III. Planting in the upper basin

Apricot trees should choose seedlings with developed roots and strong growth before sprouting, choose flowerpots with a diameter of about 20-30 cm, put a few pieces of broken tiles (to prevent rotting roots) at the bottom of the pots, and put coarse sand 2 cm thick at the bottom of the pot. in the addition of appropriate amount of nutrient soil, the nutrient soil should be mixed well with mature cow dung, sand and nitrogen, phosphorus and potassium compound fertilizer, and the planting depth should be just over the original soil surface of the seedlings. The grafting interface can not be covered with soil, the nutritious soil can be loaded to about 80% of the basin, and then watered once after the basin. If there is a large collapse, it should be filled with nutritious soil and watered down in time.

IV. Shaping and pruning

Attention to pruning young apricot trees in winter: only cut without thinning, not shrinking or thinning less, gradually turning to shrinking mainly, for apricot branches extending too long and branches too high, they should be retracted to full flower buds and short branches with large angles. only in this way can we achieve the purpose of crown control and remove erect branches with less flower buds, overlapping branches and cross branches. For the branches of apricot trees that bear too much fruit or are too old, the weaker branches in the middle and lower part of the crown should be cut short, and the medium and short branches with general flower buds should be reduced as far as possible, so as to facilitate the fruit of apricot trees in the later stage. Summer pruning is mainly used to increase the angle of branches, improve the germination rate of branches and promote the blooming of apricot flowers before apricot sprouting.

5. Fertilizer and water management

Apricot trees generally blossom around March every year, and their flowering period requires high temperature. On sunny days, the soil in the basin is kept moist, while in early spring and autumn, water is watered once every three days according to the condition of the basin.

In winter, according to the situation, it is generally inspected every half a month to prevent the soil from being too dry. Fertilization is mainly based on organic fertilizer, based on the principle of thin fertilizer and frequent application, to prevent excessive fertilizer from burning roots, from apricot flowering to fruit picking, and organic fertilizer is generally applied every 10 days or so. The main purpose is to promote fruit growth and growth.

6. Protect flowers and fruits

Apricot blossoms early, so it is easy to encounter frost, affecting the fruit setting of apricot, but we can take the following measures to prevent.

1. Apricot varieties with late flowering can be selected, such as Shaanxi Yongquan plum apricot, Shanxi Yongji white plum apricot, etc., this kind of apricot varieties can avoid frost if they bloom later.

2. For some overwintering cold-proof apricots planted on land, the pot soil needs to be watered and covered with grass before sprouting, and the crown should be sprayed with lime water, which can delay the flowering period by about 5-7 days.

3. During the expansion period, apricot buds can be sprayed with 0.1% penicillin to delay flowering for about 4-7 days.

4. Pay attention to the local weather forecast and smoke the potted garden with grass before the late frost, which can reduce the impact of frost.

5. Although apricot trees can bear fruit by themselves, in order to improve the fruit setting rate of apricot trees, it is best to carry out artificial pollination and spray urea or boron fertilizer at flowering stage.

VII. Disease and pest control

The common diseases and insect pests of potted apricot trees are mulberry scale, peach heart borer, almond bee, longicorn beetle, peach aphid and apricot disease. Control methods: regular pruning of branches and leaves, timely cutting of branches with diseases and insect pests, and dichlorvos spray can be used in the period of high incidence of insect pests.

8. Pour the basin

Potted apricot trees generally need to pour the pot once every 3 years or so. It is best to pull it out of the basin during the dormant period of the apricot tree, first remove its root mat, and then remove the soil around the root by 1 stroke 4 or so, and trim the branches at the bottom properly and replant them. If you pour the pot in the growing season, you must be careful not to hurt the roots too much, and give the right amount of shade and water spray to protect the leaves after pouring the pot.

IX. Overwintering

If the area is too cold, the potted apricot trees should be put indoors to survive the winter. when the winter temperature is moderate, you can move out and cover the pot with some grass. when the cold current comes, check whether the potted soil is dry or not. if the situation is too dry, water the apricot trees in time so that the apricot trees survive the winter safely.
