山楂育苗过去多用根蘖繁殖,若大量发展,苗源受到限制。但种子育苗,一般当年不易出苗,所以造成苗木缺乏。如何提高种子发芽率,是加速苗木繁殖的重要关键.我们自1977年连续两年进行试验,收到了较好效果。 一、提早采种和层积。山楂种子根据有关文献记载,是属于长期休眠的种子。一 Hawthorn nursery past the use of root tillering multiply, if a large number of development, Miao source is limited. However, seed nursery, the general year is not easy to emergence, resulting in lack of seedlings. How to improve the rate of seed germination is an important key to speed up the propagation of seedlings.We have been testing for two consecutive years since 1977 and have achieved good results. First, early seed and stratification. Hawthorn seeds according to the relevant literature, is a long-term dormancy seeds. one
