摘　　要：总结了藤牧一号苹果幼树早果、丰产的拉枝技术，其要点是：改冬季拉枝为夏季拉枝，以夏季采果后的8～9月份拉枝更为理想；合理确定拉枝的角度和方向，一般以主枝60°、辅养枝80°～90°为宜，拉枝的方向应根据目标树形，以枝条上下错落、互不遮挡、分布均匀为宜；合理确定拉枝的年龄和部位，以树龄3～4年生、枝龄2～3年生为佳，拉枝的位置以被拉枝条长度的1／3～1／2处为适宜；及时处理拉枝后萌发的枝条。并提出了拉枝的注意事项。The spreading shoot technique for early fruit--bearing and high yield of apple saplings of Mato 1 includes spreading shoots in August and September after harvesting fruits, keeping main spreaded shoots with 60° and accessory spreaded shoots with 80°to 90°, maintaining the well-distributed tree form, choosing trees with age of 3 to 4 years and shoots with age of 2 to 3 years for spreading shoots, selecting 1/3 to 1/2 of total spreaded shoots as the spreading position and using some technical measures to treat germinated spreaded shoots in time. The paper puts forward some points for attention in spreading shoots of apple saplings.
