1 , " 1 , 3 , 6 , 9 ~ 12 " trimming method: This technique involves pruning the scaffolding surface of the dragon vine so that on each one-meter section, three result branches are left. These branches should have between six and twelve buds. The long tip of the dragon vine is usually kept in the middle or at the end of the vine. Each year, it is pruned back and a new extension is selected from the back. In garden cultivation, the number of buds is generally slightly higher, but not exceeding fifteen, which corresponds to the " 1 , 3 , 6 , 9 to 15 " system. 　　 2 , " 1 , 2 , 1 " trimming method: This approach is commonly used for varieties such as longan and milk fruit. It involves horizontal scaffolding, where the distance between holes is set at 1 to 1.5 meters, with two to three plants per hole. A dragon vine is arranged every 50 to 60 cm on the frame surface, and single branches are alternately updated. On each one-meter section of the dragon vine, there are two short tips (1 to 2 nodes) and one middle tip. The long spreading tips are cut back to encourage growth. Each frame has a wide surface area of about 2 square meters, leaving around 14 to 20 buds per plant. Per hectare, this results in approximately 120,000 to 180,000 shoots. In semi-arid regions with sufficient sunlight, grape branches may grow more slowly, so summer pruning must be strict to ensure good bud differentiation. Usually, each panicle weighs more than 0.5 kilograms, and per hectare, yields can reach 30,000 to 37,500 kg. This method is particularly suitable for young fruit trees. 　　 3. Pruning during the fruiting period: Trees in this phase are typically between 13 and 40 years old. As the years go by, the tree's vegetative growth gradually weakens, and if not managed properly, it can lead to alternating years of high and low yield. The main goal of pruning during this stage is to balance growth and fruit production, improve light conditions, maintain tree vigor, and ensure consistent high yields.  　　 4 , pruning of aging trees: Trees over 30 to 40 years old enter the aging stage. The primary task is to rejuvenate and update the tree structure, restore its productivity, and maximize its fruit-bearing years. When pruning, main and side branches should be appropriately shortened based on their condition. If the central branch group is deteriorating, it should be removed from the base, and the canopy should be reshaped into a more balanced form. Be cautious when making cuts to prevent rot. For these older trees, long branches should be utilized to develop new fruiting branches, while existing branch groups are renewed. Extra flower buds should also be removed to ensure strong growth of the remaining branches. 　　 5, re-cutting flowers before the bud stage: Mid-March to early April, when the tree is still in dormancy, avoid allowing flower buds to grow on the upper branches. Once the flower buds become clearly visible, any extra branch groups that do not produce flowers should be trimmed or cut back to ensure a full inner canopy. If the variety is poor, consider replacing it with a better one once sap flow begins.  Hex Slotted Nut,Slotted Hex Nuts,hexagonal plated nut,Standard Din934 Nuts HANDAN ZHONGBAO IMPORT AND EXPORT TRADING CO.,LTD , https://www.hdzbfastener.com
