The method of raising seedlings by grafting of Waxberry

Red bayberry is a special fruit tree of our country, the fruit is ripe in early summer, it coincides with the season of lack of fresh fruit, its bright color, fruit sugar content of 12% 13%, sweet and sour palatable, rich in Vc, Shengjin cough, very popular in the market. However, red bayberry seedlings can not bear fruit until about 10 years after planting. In order to bear fruit earlier, grafting method is generally used in production, and half of the seedlings in the third year of planting can hang fruit. The grafting techniques of red bayberry are summarized as follows:

1. Sow seeds. The fully ripe fruits were harvested from the robust adult trees and stacked for 3 to 5 days after harvest. After the pulp rotted, the pulp was washed and the unfullness was removed. After slightly drying, the seeds were sown in sand storage. The seed sprouting rate is 40%-70%. The sowing site should choose sandy red-yellow soil with good drainage and loose soil. After sowing, the seeds are pressed into the soil with a board, which is flat with the border surface, covered with a layer of fine soil, and then covered with straw to prevent the soil from hardening. Generally, it can be germinated and unearthed one month after sowing.

2. Rootstock management. After the seedlings are unearthed, they should be managed frequently, replenish water in time and promote the growth of buds and seedlings. In order to make the seedlings sturdy, we began to pour light liquid fertilizer (rotten human and animal feces and urine) at the seedling height 3cm, apply it once a month, and do a good job of weeding, pest control and so on. When the Lignification begins at the base of the seedling and the height of the seedling is about 6~10cm, it can be transplanted.

3. Selection of rootstock. To cultivate a strong rootstock, the diameter of the rootstock is about 1cm. Determine the mother tree of the improved variety, select the middle part of the spring shoot of last year (no diseases and insect pests, full bud eyes) as the scion, pick it up and pick it up on the same day, wrap it with wet cloth or keep it fresh with sand.

4. Grafting method. The cutting method is usually carried out after sprouting and spreading leaves (from sting to the Spring Equinox). When grafting, first select the smoother side of the rootstock, cut the cortex from top to bottom with a grafting knife, just cut the xylem, cut the spare branches according to each scion and leave 1 or 2 bud holes, then cut the scion slope and affixing surface, insert the scion cutting surface into the rootstock incision, and make the two cambium aligned on one side, and wrap it with a special grafting film without exposing bud eyes.

5. Management after grafting. The new shoots germinated below the grafting interface should be wiped out in time, the scion germinating shoots should be strong and weak, 2-3 buds should be left to grow, and the rest should be erased. Lignification of new shoots can be applied to rot acquaintance feces and urine once, and then once every other month, so that thin fertilizer can be applied frequently. During the growing period of new shoots, timely control of diseases and insect pests, timely use 70% methyl thiophanate 800 times solution, omethoate 800 times solution to control anthracnose, yellow caterpillar and other pests.
