Selection of oil tea anvil sticks:
First of all, we must choose 15 to 35-year-old students to grow vigorously, and tea plants with no pests and diseases should be used as rootstocks. On the rootstock, select 5 to 7 main branches with branch diameters of 2 to 5 cm for the anvil branch. The branches of the anvil branch should be properly angled, with a clear master-slave relationship and a balanced distribution. After grafting, the grafted plants can form a good crown, which makes the distribution of the tea flowers even and beautiful. In addition to the rootstock of each rootstock, one or two main shoots should be added as vegetative shoots, and the rest should be removed. Each of the anvil branches should have 1 to 2 side branches for supplementary support, and the rest should be removed.
Grafting time options:
Camellia camellia grafting can be grafted during the growth of Camellia and Camellia in the three seasons of spring, summer and autumn. Among them, the grafting effect was better from March to June, so the scion quality was better and the climatic conditions were suitable. The scion growth period was longer, the growth was larger, and the survival rate of the graft was high. From July to August, the temperature is relatively high, shading and moisturizing measures must be fully implemented in order to achieve a satisfactory graft survival rate. From October to November, although the temperature is suitable, the survival rate of the grafts is higher, but the growth period of the scion is relatively short. After the winter, the scion shoots are not fully lignified and are prone to frost damage.
Selection of rootstock scion:
The growth of the scion mother tree and rootstock should be in a vigorous period, and the scion grafting should be carried out so that the survival rate of the anvil is high and the growth is coordinated. For scion collection of the same rootstock, different mother trees with similar flowering duration and similar growth should be selected so that the development of the canopy of the anvil can be balanced. For those with thicker basal diameters of rootstocks, it is advisable to choose the scion that grows fast and the flower type is large; if the stock base diameter is smaller, the scion with smaller leaves and smaller flower diameter should be selected. The same stock stock can graft multiple varieties of scion to form a single product, different from left to right, different from top to bottom, another color in the middle, multi-colored surrounding colorful structure.
The basic method of grafting:
Broken drill skin grafting method:
We first need to select a good anvil branch within the control of the height of 90cm on the line, the branch diameter control at 5cm sawing off, this way to retain the auxiliary side branch, the purpose of doing so is to remove the excess side branch, remove the next fracture position of the pollution Keep the tip of the shoot as high as possible in the inner part. A 3cm can be cut behind the scion of the leaf. Cut a short noodle on both sides of the long face to make the cross section a horse-shaped shape and cut the blade halfway. Cut the anatomical section of the cortex downwards and cut it to the depth of the xylem. The width and the length of the longitudinal section of the anvil branch are equal to the width and the length of the long face of the scion. Pick off the vertical incision of the anvil branch and pull it down, insert the long face of the scion into the incision of the anvil, and pull the anvil to cover the scion.
Finally remind everyone that at the end, the plastic film tape is used to wrap the interface, and the scion is wrapped with a plastic film back cover (moisturizing). In addition, the kraft paper is wrapped outside the bag (for shading purposes), and the bagging and paper shading are required. stable.
