实生苗木是通过播种繁育的苗木,也就是有性繁殖的苗木。它具有完整的根系和顶芽,对外界条件适应性强,有后期生长快、材质好、寿命长等特点。大多数树种可以用种子播种的方法繁育苗木,所以实生苗在育苗中被广泛应用,特别对一些不能无性繁育的树种,必须采用种子来繁育。因此,大力推广实生苗培育技术具有十分重要的意义,现介绍如下。1播种苗木当年生长特点 Seedlings are nursery seedlings by sowing, that is, breeding seedlings. It has a complete root and top bud, adaptable to the external conditions, rapid growth in the late, good material, long life and other characteristics. Most species can be seed sowed seedlings breeding methods, so seedlings are widely used in nursery, especially for some species can not be asexual breeding, you must use seeds to breeding. Therefore, to promote seedling cultivation technology is of great significance, are presented below. A sowing seedlings year growth characteristics
