One, the change is the key to the development of fruit trees
The severe ageing of some varieties has obviously restricted the economic income of the fruit area. What kind of varieties will be planted next year and what kind of varieties will be planted this winter must be selected so as to avoid random selection during planting. In general, high-altitude elects late-maturing, mid-high altitude (about 1000 meters) is selected for late-maturing, low-medium-altitude pre-cooking, and low-altitude precooking, which are determined according to the time of day and night.
Second, tree transformation is an urgent task
The transformation of the current tree is a highly technical work. There are several points to note when making changes:
1. Unreasonable ones cannot change, they must understand the principle of reform. To change must look for skilled and technical personnel with good returns after years of transformation to guide them.
2. The transformation of trees can not be carried out across the board, and no matter whether dense planting or sparse planting is changed according to a tree shape. According to site conditions, benefit conditions, and age-of-age landscape, etc., it is necessary to decide whether to change and how to change.
3. According to the degree of confinement. Confined and particularly serious one can be in place, not serious confined to 1 to 3 years in place.
4. Determine the method according to the tree. The juvenile tree reforms the first open angle (negative angle), slows down the polarity, and can be transformed after lots of flowers. Weak trees cannot be excessively branched.
5. Can go to one branch and not two twigs.
Third, prevention and control of pests and diseases is the key
In recent years, more or less orchard rot disease has caused more and more orchards in the orchards due to the fact that the orchards have not been confined in the air, excessive application of nitrogen to the water in the orchards, excessive ringing, excessive pruning, excessive management, overload, and poor pest control. Common problems. Check carefully before freezing and carefully control. The cotton fields in the northern fruit region have already risen and are likely to spread. During the winter renovation, if there are cotton flocs in the roots of tree shrews, they should be treated immediately and carefully controlled 1 to 2 times in the spring. The group prevented the colonization and prevented it from happening again.
