山楂苗的繁殖,多年来采用两种办法:一是利用野生山楂根蘖苗(或根)归苗圃嫁接育苗;二是利用种子育苗。由于种子不易萌发,需要经过「沤种处理」,一般从采种到播种、嫁接出圃,需要经过五年时间。这两种办法都有弱点,前者繁殖系数太低,后者繁殖速度太慢。既满足不了生产需要,又加大了育苗投资。近几年来,我们在部分社队试验,于山楂生理成熟期采种,当年冬季经过砂藏,次年播种即可出苗。这样,把山楂育苗五年出圃,提前了三年,大大缩短了育苗时间,降低了成本,加快了发展速度。 Hawthorn seedling breeding, over the years the use of two ways: First, the use of wild hawthorn root tiller (or root) nursery grafted seedlings; the second is the use of seedling. Due to the seed is not easy to germinate, need to go through “seed processing”, generally from planting to sowing, grafting out of nursery, take five years. Both of these approaches have weaknesses, with the former having a low reproductive coefficient and the latter being too slow to reproduce. Not only can not meet the production needs, but also increased investment in nursery. In recent years, we have experimented with some communes and teams in the physiological maturation stage of hawthorn. After that, the winter passes through sand reservoirs, and seedlings can be seeded in the following year. In this way, Hawthorn nursery for five years out of nursery, three years ahead of schedule, greatly reducing the breeding time, reduce costs and speed up the pace of development.
