此时除特殊需要外，一般不宜进行强度修剪。成年期苗木正处于旺盛开花结实时

At this time, except for special needs, it is generally not suitable for intensity trimming. The seedlings in adulthood are in the real-time period of full bloom and flowering. At this time, the purpose of pruning and shaping is to keep the plants healthy and perfect, so that the flowering and fruiting activities can maintain the prosperity and production, and stable production for a long time. To achieve the purpose of adjusting balance. During the aging period, the growth of the trees is weak, and the annual growth is less than the death. It is in the stage of centripetal growth and regeneration. When pruning, the main shear should be used to stimulate its recovery and it should be good at using the long branches to achieve the purpose of rejuvenation. [1]. <br>In order to keep the growth momentum between the main branches of the tree close to balance, the strong main branches should be suppressed so that nutrients flow to the weak main branches. So the principle of pruning is

At this time, in addition to special needs, it is generally not appropriate to carry out intensity pruning. Adult seedlings are in a period of vigorous flowering and strong, at this time the purpose of pruning and shaping is to maintain the robust and perfect plant, so that flowering and strong activities can long-term to maintain prosperity and production, stable production, comprehensive use of various pruning methods, and with other management measures, in order to achieve the goal of adjusting equilibrium. The growth and weakness of trees in the aging period, the annual growth amount is less than the amount of death, in the centerward growth renewal stage, pruning should be mainly strong shear, to stimulate its recovery of growth, and should be good at the use of long branches to achieve the purpose of renewal and rejuvenation.<br>In order to keep the growth between the main branches of the tree close to the balance, the strong main branch should be inhibited, so that the nutrient shunt to the weak main branch aspect. So the principle of pruning is

At this time, except for special needs, it is generally not suitable for strength pruning. The adult seedlings are in the period of vigorous flowering and fruiting. At this time, the purpose of pruning and shaping is to keep the plants healthy and perfect, so that the flowering and fruiting activities can maintain the prosperity and production and stable yield for a long time. The comprehensive use of various pruning methods and other management measures can achieve the goal of regulating balance. In the senescent period, the growth of trees is weak, and the annual growth is less than the death rate, and it is in the centripetal growth and regeneration stage. When pruning, the strong cutting should be mainly used to stimulate the recovery of growth vigor, and the bare branches should be used to achieve the purpose of regeneration and rejuvenation [1].<br>In order to keep the growth potential of the main branches close to the balance, the strong main branches should be restrained to make the nutrient flow to the weak main branches. So the principle of pruning is
