The chestnut low-dry low-crown multi-master branch has a happy-shape tree shape, and is particularly suitable for wide-row and low-density planting on steep terrain such as mountains and hills. So, how to master the main points of plastic surgery? Recently, the reporter interviewed Tian Shoule, a researcher at the Shandong Institute of Pomology. After the grafting of the seedlings is completed, the new shoots from the scion grow to 30 to 40 cm, and the stems are picked and dried. The grafted seedlings that are directly colonized are cut short at a distance of 30 to 40 cm from the ground, leaving 2 to 3 under the cut. A full shoot, after drying, promotes the creation of robust shoots to facilitate plastic surgery. Select the main branches and branches to select the upright Mongzhi from the sprouting new shoots in the year and use it as the trunk extension, and select the two lower branches as the first and second main branches, and use the lowermost one as the main branch. As the first main branch, they are arranged one after the other. When the main extension of the branch grows to 30-40 centimeters, the heart is picked again. Select two oblique branches as the third and fourth main branches from the strong buds that were picked from the second picking center. Note that the three or four main branches should be scattered and distributed with the main branches or two and avoid overlapping. The trunk extension branches continue to grow upwards and no longer pick up. If the number of main branches in the current year cannot reach the reserved amount, the main extension branches will be short-cut in the second year, and the main branch will be selected from the new shoots that promote growth. After the collateral was selected, the main branch would sprout a large number of lateral shoots. Choose from the strong branch of the main branch, with reasonable lateral branches. The first side branch is 50 to 60 cm from the trunk and is obtained by selecting natural sprouts or cauterizing. The other side shoots sprouted, leaving one for every 20 to 30 centimeters, try to choose to leave the lateral branches open at the base corner, or extend the base angle by pulling branches and supporting angles. The lateral base angle is generally larger than the main branch angle. Some of the vigorously growing lateral branches were picked and directly cultivated into fruiting branches. The results of the culture group were cut in the second year of winter, and the first to third main branches were cut short and light, and 1/3 of the raw shoots in the year were cut off; the fourth and fifth main branches were cut in light or medium and short cuts. It was 1/3 to 1/2 of the original length of the branch. The first to third main branches selected 2 to 3 lateral branches, the first lateral branch was about 60 centimeters away from the second lateral branch, the second lateral branch was about 50 centimeters away from the third lateral branch, and all the other lateral branches were removed. The fourth and fifth main branches selected the first to the second lateral branches, the distance between the lateral branches was about 50 cm, and all the other lateral branches were removed. The selected lateral branches are trimmed, and light and short cuts are made at the full shoots of the extended head to promote branching and form fruiting groups. For the resulting branch groups, 8 to 10 result branches are reserved per square meter, and part of the development branches are re-cut to cultivate the next year's resultant parent branch. After 3 to 5 years of pruning, the main stems of the low-dry dwarf crowns are basically formed in a shape of a happy-shape tree.
