2, "1,2,1" pruning method: This method applies to longan, milk and other varieties. Horizontal scaffolding, dry plastic dragon alone, hole distance 1 to 1.5 meters, 2 to 3 per hole, every 50 to 60 centimeters on the surface of a dragon vines, single branches alternately updated. The meaning of this law is that on the scaffolding surface, 2 short shoots (1 to 2 knots) and 1 mid shoot are left in each 1 meter long dragon vine. There are 2 dragons per 1 meter wide shelf, 14 to 20 buds equivalent to 1 square meter, equivalent to 120,000 to 180,000 buds per hectare. In semi-arid areas, there is sufficient light, grape branches are not easy to grow long, summer pruning is strictly controlled, and flower buds in buds at the base are often well-differentiated. Generally weighing more than 0.5 kg per panicle, it can guarantee production per hectare in 30,000 to 37,500 kg. This pruning method is more suitable for the young result tree.
3. Pruning of fruit trees during full fruit period: Fruit trees generally refer to trees from 13 to 40 years of age. The amount of trees in this period increases year by year, and the vegetative growth gradually weakens. Therefore, the main task of pruning is to regulate the relationship between growth and results, improve lighting conditions, maintain strong tree vigor, and obtain high and stable yields.
4. Pruning of the aging tree: Trees aged 30 to 40 years have entered the aging period. The main task of pruning is to update rejuvenation, restore tree vigor, maximize the number of years of results, and maintain a better yield. During specific operations, the main and lateral branches should be appropriately retracted and elevated according to their degree of weakness. If the central branch has decayed, it is necessary to saw it from the base and change the canopy to a happy shape, but care should be taken to protect the wound so as to prevent decay. For the aging tree, it is necessary to make full use of the leggy branches to cultivate new branches and branches. At the same time, the original branches should be rejuvenated, and the dense flower buds should be properly removed to ensure the vigorous growth of the branches.
5. Flowering before flowering: From mid-March to early April, trees with fewer flowers spend more time in the winter due to the inaccurate flower buds. When the flower buds are clearly identified, no flowers are used. The excess branches and branches are properly removed or retracted so that the internal condyle is fully illuminated. Trees with poor cultivar varieties can be highly seeded when the sap begins to flow.
