Planting techniques of plum seedlings How to plant plums?

There are many varieties of plum trees, but we should choose li miao with pure varieties, complete roots, strong and full, and no pests and diseases.

Step 2 choose soil

Plum trees have strong adaptability to soil. As long as the soil layer is deep and fertile, they can be planted in any kind of soil, which requires high air and soil humidity and is not resistant to water accumulation. If the orchard is poorly drained, it will cause root rot, poor growth and various diseases. Therefore, it is necessary to choose loose, breathable, deep soil layer, good drainage and low groundwater level plots for planting.

3, timely colonization

Plum trees need to be planted before the buds germinate, and the varieties planted should not be single. Different varieties with the same flowering period can be planted as pollination trees.

4. Rational fertilization

The base fertilizer of plum trees is mainly applied with late-acting farmyard manure, such as manure, compost, green manure, fallen leaves and crop straws. , and can be applied in autumn. Farmhouse manure 50- 100 kg can be applied to each adult plum tree.

Top dressing can be applied before flowering when plum trees germinate in early April, and each plant can be applied with 0.5- 1 kg of available nitrogen fertilizer or 25 kg of decomposed human excrement and urine.

Topdressing after flowering is beneficial to reduce physiological fruit drop. You can choose to apply 0.5 kg of available nitrogen and potassium fertilizer to each plum tree from late May to mid-June.

After physiological fruit drop and before rapid fruit expansion, topdressing 0.5- 1kg available nitrogen, phosphorus and potassium compound fertilizer per plant from late June to mid-August.

From the beginning of fruit coloring to harvesting, phosphate fertilizer and potassium fertilizer can be applied topdressing, or 0.2-0.3% quick-acting nitrogen fertilizer can be sprayed on the leaves, which can be combined with chemical spraying.

5. Drainage and irrigation

Plum trees need enough water in every phenological period of the year, and they need irrigation before germination, young fruit expansion and new shoot growth, and they need to be irrigated with 1 times frozen water before winter. Plum trees are afraid of waterlogging, so the garden needs to repair the drainage system to avoid waterlogging.

6, the prevention and control of pests and diseases

Erythema: You can choose to spray 1: 2: 200 Bordeaux solution when the plum trees are not blooming and the leaf buds are spreading, and at the same time remove the diseased leaves in the garden and burn them out.

Gummosis: it can strengthen the drainage in the garden, increase the application of organic fertilizer, improve the disease resistance of plum trees, and prevent and control pests and diseases on branches in time. Scrape off the flowing rubber skin with a knife, then apply Pomei 5 degree stone sulfur mixture, and finally apply white lead oil protective agent.

Aphids: Before leaf rolling in spring, 2000 times of 40% dimethoate emulsion or 4000 times of 2.5% Kung Fu EC can be sprayed. In the growing season, you can use 7 parts of 40% dimethoate emulsion stock solution, add 3 parts of water, apply the liquid around the trunk with a brush, about 6 cm wide, and wrap it with paper strips.

Peach moth: generally, turning the tree tray in autumn or spring will destroy the overwintering place of larvae in time, which will help reduce the number of overwintering insects. During the vigorous incubation period, 40% triazophos EC 1000 times or 5% Laifuling EC 2000-4000 times can be sprayed for control.
