First, Grafting method and time
The spring grafting method can be used for abdominal grafting, zygomatic grafting, skin grafting, and abdominal skin grafting. The first two methods can be performed before and after budding, and the latter two methods are performed after germination. The method used should be selected according to the thickness of the grafting site. The twigs are replaced by abdomen splicing and splicing, and the rough twigs can be connected by splicing, splicing, etc. When the trunk or main branch is missing branches, the graft can be replaced. The skin is connected to the abdomen. When the big tree is raised high, the baldness in the back of the big branch is no longer bald, and the empty grafts can be inserted in the bald zone to increase the amount of lychee and complete the tree. When grafting, a â€œTâ€ incision is made on the root bark of the rootstock. The bark above the incision cuts a slope to facilitate scion insertion. The scion adopts the wax seal scion, the best choice is a slightly curved scion. The cutting method and connection method are similar to the splicing method. The cutting surface should be flat and long. After inserting the scion, the wound was tied with a plastic strip. In addition to replenishing the skin and abdomen, the largest advantage is that the new shoots can be tied to the rootstock after it grows to avoid wind damage. The best time for grafting is the same as that for skin grafting.
Second, to change the shape of technology
The process of high-risk exchange is not only the process of replacing bad varieties with good ones, but also the process of transforming unreasonable tree structures into good tree structures. The densely planted trees are in the shape of a modified spheroidal shape or free-spinning pod-shaped tree, and the middle crown tree is shaped like a sparse layer of trunks, etc., and the main branch is selected first. The base diameter of the main branch is within 3 cm, and about 10 cm is left. Skin connection, generally insert 2 scion; diameter more than 3 cm, starting from the base of the main branch 30 cm, select the main branches of the branchlets on both sides of the fine branch group for abdominal cut, unilateral distance 30-40 cm, too far Can be grafted bald area, using the skin to make up the abdominal joint. Try not to cut grafts larger than 3 cm. In general, the number of joints per tree in the improved spheroid tree is not less than 30, and the number of spuds is not less than 40; the number of splices per tree in the free-spindle is not less than 12, and the number of spuds is not changed. Less than 20; trunk sparse form No less than 50 joints per tree and no fewer than 90 scions.
According to the medicinal part, we classify traditional Chinese medicine as Chinese medicinal herbs bark. Herba is the whole overground part of the herb. In herb medicine area, some traditional Chinese medicine use the whole body of the plant because the whole plant has important medicinal value. Sunch as POGOSTEMONIS HERBA and MENTHAE HAPLOCALYCIS HERBA.
