当前,山楂繁殖基本分为两种形式,即利用无性砧和利用有性砧法。无性砧法:由于山楂能产生较高量根系,可将其根条采回剪成15厘米长的根段,扦插出苗后待长到50—60厘米时嫁接;或者移根蘖苗到苗圃内嫁接;也可就地嫁接。此法育苗速度较快,但大量发展仍是有限。有性砧法:亦即实生砧法,先播种出苗,待长到嫁接粗度时嫁接。生产上大量利用的砧木主要是这种方法。此法主要问题 At present, the hawthorn breeding is basically divided into two forms, namely the use of asexual anvil and the use of sexual anvil method. Asexual anvil method: As hawthorn can produce a higher amount of root system, its root can be cut back into 15 cm long root segments, cuttings to be grown to 50-60 cm when grafted; or remove the tiller to the nursery Grafting; also grafting on the spot. This method nursery seedlings faster, but a large number of development is still limited. Sexual anvil method: that is, real anvil method, the first sowing seedlings, grafts to be grafted to grow when grafted. This kind of method is mainly used for the large-scale production of rootstocks. The main problem of this method
