How can we improve the survival rate of fruit trees?

1, finishing the root system. After the fruit trees were dug out of the nursery, the root system had been damaged. To reduce the area of ​​injuries, it was necessary to sort out. Use scissors to remove some of the main roots. The large lateral roots are cut flat from the wound. Do not cut them obliquely. The wounds are easy to recover.

2, finishing branches and leaves. After the excavation of roots, it is impossible to absorb enough water from the soil to evaporate the shoots on the ground, cut off 2/3 branches, and reduce the amount of transpiration, thus increasing the survival rate.

3, timely planting. Planting in the spring should be carried out after the soil is thawed and before sprouting, and planting too early or late is not conducive to the survival of seedlings. Due to different tree species characteristics, planting time should be different, peach, apricot, plum, etc. should be early, red dates, etc. should be late, generally planted immediately after soil freezing is appropriate.

4, choose high quality seedlings. The quality of nursery stock is one of the important factors affecting the survival rate of colonization. As far as possible, nursery stocks with high technical specifications should be selected such as disease-free pests, robust growth, developed root systems, and short internodes. Before planting, we must carefully select the seedlings, remove the unqualified weak seedlings, leggy seedlings, wounded seedlings, etc. and carry out seedling tree finishing.

5, planting technology. One is to apply basic fertilizer. In the planting hole, 1 kilogram of Shi Leili seaweed fertilizer, 2 kilograms of Auric acid fertilizer, and 0.2 kilograms of Aureole Bio-organic Fertilizer were planted in the soil. The second is the nutrient solution dipping root. Before transplanting, roots were immersed in a nutrient solution prepared with 15 ml of roots, 25 ml of water, and 10 liters of water. The roots were healed for 30 minutes to promote the healing of root wounds, accelerate the restoration of root growth, and increase the survival rate. The third is to release the interface film. If the grafting film is not lifted, the lower part of the grafting interface and the upper part will grow bold, while the growth of the grafting interface will not be synchronized, and it will be easy to break off from the grafted interface when the wind blows. The fourth is to flatten the root system. Seedlings are planted into a planting hole to flatten the root system and allow the root system to stretch to ensure that the root system grows normally. The fifth is to splash water. Put the seedlings into the planting hole, cover with a thin layer of fine soil, place enough water in the ampoules to connect the roots and soil tightly, and then cover one layer of soil. The sixth is to pay attention to marrying the interface. Orange fruit trees should be exposed at the time of colonization, and fruit trees such as bayberry, plum, peach and chestnut should not be exposed to the joints in order to grow normally. Seven is covered by a tree plate. After planting, the topsoil of the tree shrubs is covered with rice straw, thatch, crop straw or pig cow dung to maintain soil moisture and restore growth.

6, covering the film. After planting, the surrounding pods were made into shallow pans with the center of planting seedlings as the center and covered with 80-100 square mulches. It can effectively increase the temperature of the soil, protect the drought, and promote the early bud growth.

7, fertilizer and water management. The first and second days after the fruit trees are planted, the water and fertilizer are poured one by one, which is the key to restore the root growth. Ten days after colonization, the root callus began to recover. At this time, 15 mL of roots, 15 ml of good quality, 0.25 kg of high-nitrogen fertilization, and 50 liters of water were mixed at the time. One liter of water was applied to each root to increase the root system. Vitality, shorten the period of seedling sowing; 20 days after planting, according to the high-nitrogen fertilization 0.25 kg, 3% of methyl methacrylate, 23 grams of 23 grams of water, 50 liters of water, each dripping water 1 litre, can promote new shoots Robust and vigorous. Until August, 0.3% high-nitrogen fertilization was applied once a month, and the survival rate of seedlings was 95%.

8, set dry. According to the cultivation requirements, 35 full shoots were selected for cutting at the height of dryness. The cuts required smooth, no clefts, and sealing agents or plastic wraps to prevent dehydration and drain. In areas with frequent high winds in the spring, supportive pillars should be established to prevent the tree from destabilizing.

9, post-plant management. According to the management principle of “previous promotion and post-control”, the newly planted seedlings should be timely irrigated according to the growth status of fruit trees and soil moisture, and timely topdressing. At the same time, attention should also be paid to the prevention and control of pests and diseases during the seedling period. As far as possible, create a good environmental condition for seedling growth.
