Planting methods of Apricot seedlings

Choose deep ventilated sandy loam, plant according to planting distance of 2 meters, row spacing of 3-4 meters, apply about 20 jin farm manure in planting hole; spray potassium dihydrogen phosphate and urea during growth period, and keep soil in moist state; dry apricot trees in later stage, and then trim dead branches, dense branches, slender branches and diseased branches; artificial pollination can be carried out in sunny days, and pesticide control should be timely sprayed when diseases and insect pests occur.

I. Selection of land for planting

1. Apricot seedlings are suitable for planting in dry and flat plots with convenient drainage and irrigation. Choose deep and ventilated sandy loam soil. The soil shall not be hardened and adhered.

2, planting holes are generally 2 times the size of the soil ball, according to the distance of 2 meters, row spacing of 3-4 meters planting.

3. Apply about 20 jin of farm manure in the planting hole, cover 10cm of soil after mixing soil, put apricot seedlings into it, and cover a small amount of soil.

4. When approaching the flat ground, lift the seedlings slightly, then cover the soil again, water them gently after stepping on them, and then cultivate the soil to the root neck. When planting seedlings, remove 2/3 of the leaves and cover them with sunshade nets.

II. Fertilization and irrigation

1. In the early stage of apricot germination, some urea should be applied. When new shoots grow, some quick-acting fertilizers should be applied. The leaves are mainly sprayed with potassium dihydrogen phosphate and urea.

2. When flowering, more potassium sulfate fertilizer needs to be applied, and yield-increasing bacteria need to be sprayed throughout the fruiting period.

After the fruit is harvested, a large amount of farm manure needs to be applied for cold protection, and it can also supplement the nutrition of the trees, but the apricot trees planted in that year will not bear fruit in that year.

4, generally can apply farm manure and nitrogen fertilizer to promote growth, after planting, every 3-4 days irrigation water, continuous irrigation 30 days, and then every 15 days irrigation water, conducive to regulating the soil environment.

III. Plant pruning

1. After the planting returns to normal growth, the sunshade net can be removed and dried at a position 1 meter above the ground.

2, then separate the angle to leave branches, about 8-10, grow to 0.5 meters long can pick 5 branches to focus on culture, the rest can promote new shoots, and then continue to pick the core to promote shoots, cultivate several levels of branches, maintain a good angle, remove dense branches.

3. Fruiting trees are mainly pruned dead branches, dense branches, slender branches and diseased branches, which is conducive to improving the crown structure, and then cultivating the fruiting branch group. In addition, the aging trees should be truncated and rooted, and the weak branches should be removed and the strong branches should be cultivated again.

IV. Daily management

1. If the humidity is too high, it will not be conducive to apricot flowering, pollination and fertilization, and will also lead to a decrease in the fruit rate. Therefore, artificial pollination can be carried out in sunny days. Due to the high temperature in summer, diseases and insect pests are easy to occur after rain. At this time, pesticides should be sprayed in time to kill pests.

In addition, receiving sufficient sunshine is conducive to the expansion and quality improvement of fruits, so it is necessary to ensure that different nutrients are supplemented at different times.
