Planting techniques of fruit trees, advantages of planting fruit trees in winter

Seedling selection: choose and buy high-quality saplings with a height of about 1-1.5m and a base diameter of about 1cm. Planting: planting should be in late October to early November, planting depth should be more than the original seedlings. Post-management: it is necessary to do a good job of covering plastic film and drying correctly.

1. Planting techniques of fruit trees

1. Select saplings

The main results are as follows: (1) in order to plant fruit trees, we should choose seedlings that are free of diseases and insect pests, and those that do not have fallen leaves in the initial stage.

(2) the high quality grafted seedlings belonging to the first year are selected, the height of the seedlings is 1-1.5m, and the basal diameter is about 1cm, which requires that the rhizome must be free from defects.

(3) diseased seedlings, aging seedlings and thin seedlings should be excluded when selecting seedlings.

(4) about 7 days before the emergence of fruit trees, the planted soil should be watered once to prevent the injury of the rhizome during seedling emergence, which can ensure the integrity of the rhizome and the seedlings after long-distance transportation.

(5) the seedlings should be raised with a small amount of mud, then packed in plastic bags or wrapped in wet grass, and the seedlings should be covered with a canopy during transportation.

2. Plant seedlings

The main results are as follows: (1) the seedlings are suitable to be planted from late October to early November, and the planting holes of 50-80cm square are dug before planting.

(2) when digging holes, the topsoil and the soil inside should be stacked separately, and about 20 jin of soil and miscellaneous fertilizer should be applied to each hole. After the fertilizer and topsoil are mixed evenly, half of them should be placed around the planting hole and the other half should be backfilled in the planting hole.

(3) pour at least 1 bucket of water in each hole, then stir the soil and water in the hole into a thin mud with a spade, stretch the roots of the seedlings, backfill the topsoil around the planting hole into the hole, wait for 2-3 hours for water to permeate, then gently compact.

(4) the planting depth of seedlings is usually more than 3-5cm of the original seedlings and planting marks.

3. Post-management

The main results are as follows: (1) after planting, the seedlings can be covered with plastic film and play the role of protection and heat preservation, so as to speed up the healing of the rhizome and prolong the growth life of the rhizome.

(2) if plastic film is not covered after planting, it is necessary to cultivate soil on the branches of tree seedlings, covering grass or the base of tree seedlings, and the height of soil pile is 30-40cm, so as to improve the cold protection ability of tree seedlings.

(3) the branches of the seedlings should be fixed before winter, and the unsubstantial parts of the seedlings should be trimmed off.

(4) the height of fixed drying should be determined according to the variety of fruit trees. Fruit trees usually have a fixed dry height of 70-80cm. Lead oil should be smeared on the wound to avoid water evaporation.

(5) after Ching Ming Festival in the second year, it is necessary to uncover the plastic film or dig up the mound and pour water once to promote germination.

(6) ploughing soil and covering plastic film in time after watering is beneficial to preserve soil moisture, increase soil temperature and promote the growth and development of seedlings.

Advantages of planting fruit trees in winter

The main results are as follows: 1. The temperature before winter is more suitable for planting fruit trees, and it is also the second peak period of rhizome development of fruit trees, which can promote the wound healing of fruit trees' roots and accelerate the absorption of nutrients by fruit trees, which is beneficial to the growth and development of fruit trees in the coming spring.

2. The temperature is low in winter, the leaves have fallen off, the body fluid of the fruit tree will not flow, and the tree will stop growing, so it does not need to absorb a lot of nutrients.

3. When planting injured fruit trees in winter, the demand for nutrients absorbed by the rhizome is small, and there is no need for a large amount of supply to input the tree, mainly to supply the wound healing of the rhizome, and to precipitate some nutrients during the period.

4. Winter is the key period to promote the healing of the roots of fruit trees. by the spring of the second year, the wounds of the roots of fruit trees have all healed, so they can be put into normal absorption and transport work in time to provide sufficient nutrients for fruit trees.
