Spring planting fruit trees master nine strokes to ensure survival rate

First, finishing the root system

After the fruit trees are dug out from the nursery, the roots have been damaged, and in order to reduce the injured area, it is necessary to sort out. Use scissors to remove some of the main roots. The large lateral roots are cut flat from the injured area. Do not obliquely cut and the wound is easy to recover.

Second, finishing the leaves

After root excavation, sufficient water can not be absorbed from the soil for evaporation of the upper branches and leaves, and 2/3 leaves are cut off to reduce the transpiration and thus increase the survival rate.

Third, timely planting

Spring planting should be carried out before and after seedling germination. Planting too early or late is not conducive to seedling survival. Due to the different characteristics of the tree species, the planting time should be different. Peach, apricot and plum trees should be early, and jujube trees should be late.

Fourth, the selection of quality seedlings

The quality of seedlings is one of the important factors affecting the survival rate of fruit trees. The seedlings with high technical standards should be selected as much as possible, such as no pests and diseases, strong growth, developed roots, and short internodes. Before planting, carefully select seedlings, remove unqualified weak seedlings, long seedlings, wounded seedlings, etc. and carry out seedling finishing.

V. Colonization technology

One is to apply enough base fertilizer. In the planting hole, 1 kg of seaweed fertilizer, 2 kg of bacterial fertilizer and 0.2 kg of bio-organic bacteria are applied to the planting hole. The second is the nutrient solution soaked in roots Before transplanting, the root system was immersed in a nutrient solution prepared with 15 ml of roots, 25 ml of water, and 10 liters of water to promote root wound healing, accelerate root growth and increase survival rate. The third is to remove the film at the interface. If the grafting film is not released, there will be thickening of the lower part and the upper part of the grafting interface, and the growth of the grafting interface is not synchronized, and it is easy to break from the grafting interface when the wind is blown. The fourth is to level the root system. When the seedlings are placed in the colonization hole, the root system should be leveled to stretch the roots to ensure normal root growth. The fifth is to soak up the water. Put the seedlings into the planting hole, cover a thin layer of fine soil, pour the water into the ampoule to make the roots and soils tightly connected, and then cover a layer of soil. Six is ​​to pay attention to the marriage interface. Persimmon fruit trees should be exposed when they are planted. Li, peach, chestnut and other fruit trees should not reveal the marriage interface, in order to grow normally. Seven is the tree cover. After planting, cover the topsoil of trees with straw, thatch, crop straw or pig manure to maintain soil moisture, which is conducive to the growth of fruit trees.

Sixth, covering the mulch

After the fruit trees are planted, the surrounding stalks are made into a shallow pot shape and covered with a mulch film of 80-100 cm square. It can effectively raise the ground temperature, resist drought and protect the buds, and promote the early growth of buds.

Seven, fertilizer management

It is the key to restore root growth by pouring fertilizer water on the 10th and 20th day after planting. 10 days after planting, the root callus began to recover. At this time, the root system was adjusted according to the ratio of 15 ml of roots, 15 ml of very good, 0.25 kg of high nitrogen and liters of water, and 50 liters of water. Vitality, shortening the slow seedling period; 20 days after planting, according to the high nitrogen fertilizer fertilization 0.25 kg, 3% nail cream · 23 grams of oral malformin, water 50 liters ratio of liquid, one liter of water per liter, can promote new The buds are strong and strong. By August, 0.3% high-nitrogen fertilization will be applied once a month, and the survival rate of seedlings will reach 95%.

Eight, fixed

According to the cultivation requirements, there are 35 full-bud cuts at the fixed dry height. The cuts are required to be smooth, free of splitting and treated with a sealing agent or a plastic film to prevent water loss and drying. In areas with frequent winds in spring, pillars should be set up to prevent trees from shaking.

Nine, post-plant management

In accordance with the management principle of “pre-promotion and post-control”, the newly planted seedlings are timely irrigated according to the growth status of the fruit trees and soil moisture, and timely topdressing, and at the same time pay attention to the prevention and control of pests and diseases in the seedling stage. Try to create a good environmental condition for the growth of fruit trees.
