Tree trees with disordered trees are common in production parks that are left unattended or not yet mastered by technology. There are more peach trees from 3 to 5 years old. They mainly display main branches and often have 5 to 7 main branches, main branches, and main trees. The side branches are crowded with each other, and the major branches on the main branch are roughly the same in thickness as the main branch. The main side branches are upright. The large and medium-shaped branches cannot be arranged or configured badly. There are many internal standing branches, poor illumination, and many deaths of the branchlets. Poor formation, low yield. The solution is as follows:
I. Planed to saw too many main branches
According to the "multi-branch stick-shape" structure for plastic surgery, the main branches are usually sawn in upright and small angles during winter pruning, and 1 to 2 main branches are sawn each year to prevent premature aging of tree vigor caused by excessive sawing for one year. At the end of the canopy, 3 to 5 main branches are reserved, and 1 to 2 lateral branches and large and medium branches are reserved on each branch. In summer and autumn, the angle of the main branch is drawn to 45 to 60 degrees, and the angle of the side branch is 70 to 80 degrees. The main branch should be evenly distributed. After 1 to 2 years, the tree is transformed.
Second, equipped with a good team
Due to the large and large saw cuts, the incisions are often erected at the incisions in the following year. In order to control the growth and promote flowering, it is necessary to wipe out the other new shoots and keep one new shoot. When the length is 35 to 45 cm, the tip is twisted; the branches are twisted or drooped to ease the growth potential and promote flower bud formation. After the end of July, the tip of the auxiliary tip was towed, and the excessive and dense new tip was sparsered, so that the tip pitch of the tip was maintained at about 20 cm. Generally, after one tipped branch was twisted, 6-8 tip posts were retained. . When pruning in winter, trim the ratio of 2:1 to the fruit branches. Each long fruit branch retains 8 to 10 flower buds, the middle fruit branch retains 4 to 6 flower buds, and the growth branch leaves two buds. In the autumn and winter of the year, the leggy branches can form medium and small branches with sufficient internal force, without affecting the light and normal results. There are 2 or 3 such middle and small branch groups in the middle and lower parts of each main branch. The results are good both inside and outside the whole tree. The light is sufficient and the trees are plump, so that high yield and stable yield can be maintained.
Parenteral nutrition (PN) is provided intravenously as the nutritional support for patients before and after surgery and those in critical condition. Total nutrition from parenteralnutrition is called total parenteralnutrition (TPN).
