Organize the root system
After the fruit trees are dug out from the nursery, the root system has been damaged. In order to reduce the injured area, it is necessary to organize. Use scissors to remove part of the main root, and the large lateral root should be cut flat from the injured area. Do not cut diagonally. The wound will recover easily.
Organize branches and leaves
After the root system is excavated, sufficient water cannot be absorbed from the soil for evaporation of the above-ground branches and leaves, and 2/3 of the branches and leaves are cut to reduce transpiration, thereby increasing the survival rate.
Plant in time
Planting in spring should be carried out after the soil is thawed and before the seedlings germinate. Early or late planting is not conducive to the survival of the seedlings. The planting time should be different depending on the characteristics of the tree species. Peach, apricot, plum, etc. should be early, and red dates should be late. Generally, it is best to plant immediately after the soil has thawed.
Choose good seedlings
The quality of seedlings is one of the important factors affecting the survival rate of colonization. Seedlings with high technical standards should be selected as far as possible, such as no diseases and insect pests, strong growth, well-developed root systems, and short internodes. Before planting, carefully select seedlings, remove unqualified weak seedlings, elongated seedlings, injured and diseased seedlings, and organize seedlings.
Colonization technology
1. Pay attention to applying plantar fertilizer and nutrient solution to soak the roots, which can promote root wound healing, accelerate the restoration of root growth, and increase the survival rate.
2. Remove the film at the interface. If the grafted film is not lifted, the lower and upper part of the graft will grow thicker, and the growth of the graft will not be synchronized, and it will easily break from the graft when a strong wind blows.
3. Level the root system. The seedlings are placed in the planting ditch, the root system should be leveled, and the root system should be stretched to ensure the normal growth of the root system. Put the seedlings into the planting ditch, cover with a thin layer of soil, pour enough root water to connect the roots and soil tightly, and then cover with a layer of soil.
4. Pay attention to the interface. When citrus fruit trees are planted, the marrying joints should be exposed, while the marrying joints of bayberry, plum, peach, chestnut and other fruit trees should not be exposed for normal growth. After planting, cover the topsoil of the tree bark with rice straw, thatch, crop straw or pig and cow dung to keep the soil moisture and restore growth.
Cover with mulch
After planting, raking the surrounding seedlings into a shallow pot shape with the planting seedlings as the center, and covering 0.8-1 square meters of plastic film. It can effectively increase the ground temperature, resist drought and protect moisture, and promote early bud growth.
Fertilizer and water management
Watering the fruit trees on the 10th and 20th day after planting is the key to restoring root growth.
Set dry standard
According to the cultivation requirements, choose 35 full buds to cut at the fixed height. The cuts should be smooth and free of splitting. They should be treated with a sealing agent or wrapping plastic film to prevent dehydration and draining. In areas with frequent strong winds in spring, pillar supports should be set up to prevent the tree from shaking.
Post-plant management
Newly planted seedlings follow the management principle of “promote before and control afterwardsâ€, irrigate them in time according to the growth status of the fruit trees and soil moisture, and apply fertilizer in a timely manner. At the same time, attention should be paid to the prevention and control of plant diseases and insect pests during the seedling stage, so as to create a good Environmental conditions.
