1. Fruit farmers must not blindly prune fruit trees. They should follow the three principles of "pruning according to the tree, shaping according to the branches, overall consideration, combining long and short, focusing on light and combining light and heavy". . Among them, "pruning according to the tree and shaping according to the branches" means that pruning should be carried out in combination with the initial tree shape requirements of the orchard and the specific conditions of different individual trees, so as to achieve a situation that is tangible but not dead, alive but not chaotic; "overall planning and consideration, "Long-term combination" means that when pruning fruit trees, all factors such as the plant and the fruit should be taken into consideration. Pruning should be done in the long term. You should not be in a hurry to save labor and time, but should prune young trees to promote growth and shape. Mainly, the pruning of fruit-bearing trees should take into account both growth and fruit; "mainly light and combine light and heavy" means that when pruning, especially when pruning young trees, the amount of pruning should be reduced to avoid excessive pruning. Causes the phenomenon of plant growth inhibition.
2. For most fruit trees, pruning is usually carried out in two periods of the year: winter and summer. According to the phenological period, they are pruning during the dormant period and pruning during the growing period. Among them, pruning during the dormant period mainly involves cutting off or shortening some unnecessary branches as well as diseased branches and dead branches remaining on the tree. At the same time, it is also necessary to select the backbone branches, central branches, main branches, sub-main branches and other branches to establish the establishment of the tree. Make plans for high-yielding trees. Pruning during the growth period is mainly to inhibit the growth of new shoots, promote the formation of plant flower buds, improve the ventilation and light transmission conditions of the tree, increase light and utilization efficiency, and produce high-quality fruits.
3. Fruit farmers should observe the overall growth of the tree when pruning, and then proceed from top to bottom, from outside to inside, and from thick to thin. Do not do it directly when you see the fruit trees, without considering the basic growth conditions of the fruit trees and the needs of tree shape shaping, just to meet the needs of ventilation and light transmission. This can easily cause the trees in the orchard to be disorganized and seriously affect the later field management.
4. After pruning, the wound should be promptly smeared with Bordeaux liquid, lime sulfur solution or 0.01%-0.1% naphthalene acetic acid to avoid wound infection, bacterial invasion, and adverse effects on tree vigor and even yield. If this operation is not handled properly or is not performed at all, poor wound healing can easily lead to xylem rot, destruction of conductive tissue, abnormal water and nutrient transportation, weakened tree growth, or even death.
5. When pruning, fruit farmers should first disinfect pruning tools such as pruners and hand saws; the remaining branches after pruning should be taken out of the orchard in time, especially those infected with diseases, and then Bury or incinerate at appropriate locations.
