摘　　要：研究了不同定干高度对无分枝的矮化自根砧苹果苗生长发育的影响。结果表明,矮化自根砧M9T337嫁接烟富3组合苗采用大苗建园,适宜定干高度为150 cm左右,生长一年的幼树树高可达2.2 m以上,中心干上平均抽生16条以上长度35 cm以下的小主枝,相比于定干高度130 cm和140 cm的苗木,更符合高纺锤树形的树体结构指标要求,能尽早形成结果骨架,达到早果、丰产、优质的生产目的。The effects of different heading heights on the growth and development of unbranched ‘Yanfu 3/M9 T337’ annual saplings were studied. The results showed that using large seedlings of M9 T337 dwarfing rootstock to establish apple orchards, the suitable heading height was about 150 cm, the height of annual saplings could reach more than 2.2 m, and the average number of small main branches with a length of less than 35 cm was more than 16 on the central stem, which met the requirements of high spindle tree structure index, and could form the fruit skeleton as soon as possible, so as to achieve the production purpose of early fruit, high yield and high quality.
