2. Pruning is the most suitable when the fruit trees don't grow at all. Pruning in spring is generally around March, pruning in summer is generally around June and July, and pruning in late autumn is best in1October of a year, because proper pruning in winter can greatly improve the cold resistance, drought resistance and stress resistance of fruit trees during the dormant period and overwintering period of that year.
3. March to April in spring March to April in spring, because the temperature and humidity at this time are more suitable, which is conducive to the restoration of trees. When pruning trees, cut off the branches of plants that are not growing well and make them grow stronger year by year. August to September in autumn, because the temperature and humidity are relatively low at this time.
4. Pruning of fruit trees can be done in spring and autumn and summer. 2. Pruning in spring is generally around March, pruning in summer is generally around June and July, and pruning in autumn is appropriate in August and September. 3. Pruning of fruit trees depends on different varieties.
5. Pruning during the growth period of fruit trees can be divided into three periods: spring pruning, summer pruning and autumn pruning. In the north, it is usually pruned in mid-March, pruned in summer in May, and pruned in autumn in June, 865,438+00. In addition, pruning frequency depends on tree age, tree potential cultivation management technology and site conditions.
6. Apple trees grow slowly, and it is not easy to grow new branches. Therefore, pruning should pay attention to the time, and it is best to do it after defoliation in winter and before germination in spring, without affecting winter and the next year. When pruning, if it is a young branch, it should be cut lightly and the long branch should be cut short. If it is an adult fruit tree, it is necessary to cut off too dense branches, diseased branches and dead branches.
7. Pruning of fruit trees can be divided into winter pruning, spring pruning and summer pruning. Different pruning methods are different in winter pruning and autumn pruning. Because of the long time and abundant labor, it is the most important pruning season. Its main function is to shape trees, adjust fruiting branches and cultivate fruiting branches.
8. Choose 3-4 layers of main branches with small crown and sparse layers. After selection, clean up the dense branches that affect the growth of backbone branches, and clean up 1-2 branches every year. Strive to keep 3-4 small main branches every year after 2 years of cleaning. The main branches are about 20 cm apart. Prune the branches of the second fruit tree that are too dense.
9. Apple trees can be pruned all year round, but the emphasis of pruning is different in different seasons. Apple trees can be pruned in winter. From the second half of autumn defoliation to the beginning of 65438+February, and from the first half of spring germination in southern Shandong to the middle of March. It is best to finish the winter pruning before New Year's Day.
10, fruit trees can be pruned all year round, but the pruning methods and points are different in different seasons. Plastic pruning is mainly carried out in winter dormancy period, and pruning in other seasons has its own emphasis. Pruning in winter is carried out after defoliation of fruit trees and before germination in spring. The main purpose of pruning this season is to organize the steady growth of trees.

12. Pruning in growing season is generally called summer pruning, which has quick effect and strong effect. It is mostly used for the vigorous growth of young trees to alleviate the growth potential, promote flowering, or adjust the relationship between growth and fruit. Summer pruning methods include pruning and girdling, taking branches to soften deciduous fruit trees, and combining "wiping buds" and "releasing buds" of citrus.
13. There are two kinds of fruit tree pruning: winter pruning and summer pruning. Pruning is mainly to cut off pests and weak branches on the back of drooping branches. Pruning can control the yield of fruit trees and improve fruit quality. Pruning is for fruit tree shaping, pear tree is in the form of three main branches, peach is in the form of three main branches, pomegranate is in the form of three main branches.
Pruning should be carried out in May, late October and early February of 165438+65438. In the early stage of peach growth, buds and leaves near the bottom of the root system should be cut off to reduce the consumption of water and nutrients. In the middle growth period of peach trees, the branches with dense growth should be randomly thinned to improve the ventilation and light transmission of the plants and ensure the branches.
15, before spring sowing, the northeast is cold in winter, and winter scissors are easy to cause streaking.
16. Prune cherry trees in summer 1. In the 35 cm leaf clump stage, the buds are removed and wiped off, and all the competitive buds of cutting buds of strong branches and extended branches on the trunk and near the big incision are wiped off, and the double buds are removed to leave a single bud, and the waste buds of pests and diseases are removed to reduce the long fruitless branches.
17. Grasp the pruning time. Pruning in summer is carried out in the growth period, and it is best to do it early in May-August. Too late is not conducive to the growth of trees and the formation of flower buds. 3. Control the amount of pruning. Because summer pruning is at the peak of apple growth, it is not only the vigorous period of consuming and making nutrients, but also the most prominent period of contradiction between nutritional growth and reproductive growth.
