一、选择适宜的砧木和品种 因无病毒苹果树不能利用高接更换品种,建园时一定要统一规化布局,根据各地的地理、气候环境和市场条件,选择适宜的砧木和品种。砧木分实生砧和营养砧。实生砧就是用种子繁殖作砧木的种苗,种子来源广,主要有八棱海棠、平邑甜菜、山定子等,主要作为苹果无病毒乔化苗的根砧和矮化苗的基砧;营养砧主要有矮化砧M_9、M_(26),半矮化砧M_7、MM_(106),极矮化砧M_(27),等。从长远看,无毒矮化是苹果发展的方向。
First, select the appropriate rootstocks and varieties Because of the virus-free apple trees can not take advantage of high replacement varieties, construction park must be unified and standardized layout, according to the geographical, climatic conditions and market conditions, select the appropriate stock and varieties. Rootstock subsistence anvil and nutrition anvil. The rootstock is the seedling rootstock seedling propagation, seed sources wide, there are eight-begonia, beech, mountain statues, mainly as apple-free rootstock and Qiaohua seedlings anvil rootstock; nutrition Anvil mainly dwarf anvil M_9, M_ (26), semi-dwarfing anvil M_7, MM_ (106), dwarfing anvil M_ (27), and so on. In the long run, non-toxic dwarf is the direction of apple development.
