优良苹果品种的推广、普及,首先必须解决苗木的快速繁殖问题。以往生产所用的嫁接途径,因受砧木和接穗两方面的制约,使快速繁殖往往难以实现。繁殖营养系苹果砧木苗,用常规方法增殖系数很低;优良苹果品种的接穗也常因来源有限,而难迅速提供。直接采用扦插等无性繁殖方法,因苹果栽培品种一般都不易生根,致使在两千多年的苹果生产中尚无采
Good apple variety promotion, popularization, we must first solve the rapid propagation of nursery stock. The grafting approach used in the past production, due to the constraints of both stock and scion, make rapid propagation is often difficult to achieve. Reproductive and nutrition system of apple rootstock seedlings, with a conventional method of proliferation coefficient is very low; good apple varieties often because of limited sources of scion, but difficult to quickly provide. Cuttings and other direct use of asexual reproduction methods, because Apple cultivars are generally not easy to root, resulting in two thousand years of apple production has no mining
