“短枝型”是苹果的一种可遗传的生长型芽变。也称作“紧凑型”。它与乔化品种相比,具有如下特点:1、树体矮小、紧凑,适合密植栽培,便于管理。一般短枝型品种的树冠约为其原品种的1/2～2/3。这给修剪、采收、喷药等带来很大方便。2、萌芽率高、成枝力差。树体具备这一特点,便显得长枝稀疏,短枝密挤,调查树体参数,短枝率较高。3、树势稳定,结果较早。短枝型苹果的生长势较一般乔性品种偏弱,新梢年 Spur is a heritable growth-type shoot of apple. Also called “compact.” Compared with Qiaohua varieties, it has the following characteristics: 1, the tree is short and compact, suitable for close planting, easy to manage. The spruce canopy is about 1/2 ~ 2/3 of the original variety. This gives pruning, harvesting, spraying and other great convenience. 2, high germination rate, poor branch force. Tree with this feature, it appears that the long branches sparse, short crowded crowded, survey tree parameters, short shoot rate higher. 3, the tree is stable, the result is earlier. Spur-type apples grow more general than Joe’s weak varieties, shoots years
