果树一般多在春季种植,此时树体的新陈代谢仍处在较低水平,种后树体生理活动转入旺盛时期,易发根、抽芽、管理方便、成活率高。桂南地区有冬季种植的习惯,冬植苗树体贮备一定的养分,生理活动相对缓慢,植后成活率较高。冬植苗一般不抽芽,根系生长缓慢,从种植到开春这段时间,树体逐渐恢复因移植所引起的生理失调,能为翌年春季抽梢生长打下基础。但在桂北冬季 Fruit trees are generally planted in the spring, when the metabolism of the tree is still at a low level, after the tree species physiological activity into strong period, easy to root, bud, easy management, high survival rate. Guinan area has the habit of planting in winter, winter planting seedling reserves a certain amount of nutrients, physical activity is relatively slow, high survival rate after planting. Winter seedlings are generally not bud, the root growth is slow, from planting to open spring time, the tree gradually recovered due to the physiological imbalance caused by the transplant, can lay the foundation for the next spring spring shoot growth. But in winter in northern Guangxi
