Pruning in dormant period, deciduous seedlings can be done after deciduous, but evergreen seedlings have no obvious dormant period, pruning after stopping growth, winter pruning will affect seedlings, generally pruning in early spring after winter; pruning in the growing season, The pruning of seedlings should not be too late, otherwise it will cause the secondary shoots to consume too much nutrients, which is unfavorable for the growth of new shoots. At the same time, the appropriate amount of pruning will reduce the accumulation of nutrients and prevent the growth of seedlings. <br>Deciduous trees are trimmed to maintain the growth of the treetops. The side branches above the branching point can be selected to leave the first layer of skeleton branches every 35-55cm. On the skeleton branches to maintain their top growth advantage, keep a second at a certain distance. Grade branching, and so on. After three branches, you can let it grow naturally. At this time, the beautiful canopy has been cultivated and formed. Cut off long branches and drooping branches regularly every year; evergreen tree pruning, leave the main branches of evergreen trees, scientifically handle skeleton branches, pruning and sparse branches to maintain even distribution of branches; hedge trimming, hedge seedlings have strong germination ability, side branches It has strong branching ability and is very resistant to pruning. Regular pruning is usually used to promote the sprouting of new shoots, lively appearance and beautiful appearance. It can also avoid the problems of internal defoliation and emptying, lower unconsciousness, etc.; pruning of vines, seedlings of vines Mainly to cut short branches to promote the growth of branches

Another secondary branch should be reserved at a certain distance, and so on. After the three-layer branch, it can be allowed to grow naturally. At this time, the beautiful crown has been cultivated. Cut off the long branches and vertical branches regularly every year; prune the evergreen trees, keep the main branches of the evergreen trees, scientifically handle the skeleton branches, trim the sparse branches to keep the branches evenly distributed; hedge pruning, Hedgerow seedlings have strong germination ability, developed lateral branches, strong branching ability, very resistant to pruning, and the regular pruning method is usually used to promote the vigorous new buds, vigorous appearance and beautiful shape For vine pruning, the main method is to cut short branches to promote the growth of branches. In case of diseased branches, the short branches should be cut off in time<br>
