Dragon's Toad is a deciduous tree of the leguminous family. Its branches are bent downwards, and the canopy is usually trimmed into umbrellas. It is a very good green tree species. The grafting techniques are described below.
First, preparation before grafting In spring, in the country's nursery, choose seedlings with breast diameter of 5 cm or more to stay 1.5-2.5 meters to dry (you can also determine the height of dryness according to the user's requirements). When the new branch of Sanghae grows to about 10 centimeters, 6-8 branches with different orientations and even distribution are selected and the rest are removed from the base. The height at which these branches are placed in the trunk is preferably in the range of 10 cm. If the number of shoots is insufficient or unevenly distributed, the branches adjacent to the vacant ones may be left with 5 centimeters to achieve the desired requirements.
Second, the second year of transplanting The end of March and early April, according to the spacing of 1.5 meters 2 meters with soil transplanting, watering after transplanting, to be received.
Third, grafting is conducted in mid-to-late April. Scion selection: Select the branches of the tree, which is beautiful and free from pests and diseases. The collection of shoots can be performed in conjunction with the trimming of the mother tree. Grafting: Use woody buds. First in the smooth part of the base of the rootstock branches, 5-15 cm from the base knife, gradually cut down, deep to the xylem, and finally cut out the oval interface, the length of about 2-3 cm. About 1 cm of the upper part of the full shoots in the middle of the scion is cut into a knife, and it is gradually cut down. It also reaches deep into the xylem, and the elliptic bud plate is cut to about 1 cm below the shoot. The length, breadth and width of buds should be slightly smaller than those of the rootstock. Place buds on the rootstock and align the sides. If the bud piece is small, one side of the bud piece can be matched with the noodles of the rootstock. Then wrap it with plastic film.
4. Immediately after grafting management, cut 1/2 of branches. Leave a new branch at the front end of each branch, leaving all others sparse. About 20 days later, an anvil was cut at 1 cm from the tip of the bud, and excess sprouts were often wiped off. According to the growth condition of the tree, the heart is plucked at the pendulous branches of the branches, and the branching volume is promoted. Generally, the heart is picked twice. In mid-June and mid-July, topdressing was performed twice, with nitrogen fertilizer as the main component, and timely watering in conjunction with topdressing, and prevention and control of pests and weeds were eliminated.
