1, young tree period: young tree pruning is to adjust the tree shape, expand the crown of the fruit tree, increase the number of branches of the fruit tree, and make the fruit tree perform photosynthesis better. Reasonable pruning in the young tree period can not only improve the yield and quality of fruit trees, but also make fruit trees bear fruit early.
2. Full-fruit period: Pruning in full-fruit period is mainly to cut off diseased branches, weak branches and new branches, so that trees can develop better, fruit trees can grow and bear fruit in balance, and a good tree structure can be maintained, thus prolonging the fruit-bearing life of trees.
3. Aging period: During the aging period, the nutrient absorption of fruit trees becomes worse. Therefore, in this period, the branches that affect the nutrient absorption and photosynthesis of fruit trees should be cut off in time, so that the robust branches can better absorb nutrients and make the fruit setting of fruit trees reach a higher level.
Common pruning methods: coring, short cutting, draining and pruning.
1, coring is to remove the tender branches, control the growth length of branches and balance the nutrition of fruit trees.
1, short cut: cut off some branches of fruit trees, so that the nutrition of fruit trees can be better supplied to strong branches and unnecessary nutrition consumption can be reduced.
3. Thinning: Cut off diseased branches, dead branches and clumped branches to make the canopy better ventilated and transparent.
4. Take the branches: gently crush the phloem and xylem of the branches that grow too vigorously by hand to inhibit the growth direction and growth of the branches. Pruning of fruit trees should be carried out every year, or according to different growth stages of fruit trees. The principle of pruning is to give priority to light and combine light with light; Overall consideration, combining long and short; Because trees are pruned, they follow the branches. Pruning can be carried out according to the growth and actual situation of fruit trees.
After pruning, apply some water-soluble fertilizer from Woye to balance the nutrition of the tree.
