Introduction of grafting time and method of Waxberry

Red bayberry is a kind of sour and sweet delicious fruit, which begins to mature and appear on the market in May and June every year, and is deeply loved by consumers. There are many varieties of bayberry, and the varieties planted in different places vary according to the local geographical environment and climate. In order to set many fruits and grow well, we often take the method of grafting. Let's take a look at the time and method of grafting of red bayberry.

1. Grafting time of Waxberry

The suitable time for bayberry grafting is before sprouting in spring, usually from early February to late March, when the climate is more suitable, and after the grafting survives, it can germinate and grow immediately.

The time of grafting can not be later than that of Ching Ming Festival at the latest. If the grafting is too late, the fluidity of bayberry sap will be relatively large, and too much liquid will flow out during grafting, thus affecting the survival rate of grafting. After knowing when the bayberry tree is grafted, the method of bayberry grafting can not be left behind.

2. The grafting method of Waxberry.

1. 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.

2. Rootstock selection

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.

3. Grafting method

① was grafted in situ and the root system was cut off. It is often used for 2-3-year-old rootstocks. After grafting, it goes deep from both sides of the rootstock cultivation bed and cuts off part of the main and lateral roots.

② was grafted in different places. Before grafting, dig up the rootstock, cut off some of the main and lateral branches, change the land for planting, and then graft.

③ indoor grafting. The rootstocks were dug up and grafted indoors for 2-3-year-old rootstocks or 3-year-old 4-year-old rootstocks excavated from the mountains, and then pseudo-planted or directly planted on the planting site.

④ leaves branches for grafting. The rootstocks are planted first, and then grafted on the spot, which are widely used for large rootstocks. That is, the grafting is carried out on the main branch and the other branch is left as a "hanging water branch" to attract water to flow to the branch and slow down the growth potential of the grafting part so as to improve the survival rate of grafting.

3. 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 topiramate 800 times solution to control anthracnose, yellow caterpillar, and so on.
