红花国槐嫁接繁殖技术研究

Study on Techniques Grafting Propagation in Red-Flower Sophora japonica

摘要: 国槐是重要的园林绿化树种，全国各地每年需要大量的国槐苗木。国槐苗木培育方法很多，其中嫁接育苗成活率高、生长快、苗木质量好，易培养出健康的国槐大苗。本文研究了红花国槐多种嫁接繁殖技术，得出接穗粗度为1.0 cm~1.5 cm，砧木在3 cm粗以下时采用劈接成活率最高，当砧木粗度在3 cm以上时，采用切接和插皮接两种技术嫁接成活率高，且嫁接速度快、伤口愈合快、操作简单、易掌握。

Abstract: Sophora japonica is an important tree species for landscaping. A large number of Sophora japonica seedlings are needed every year all over the country. There are many ways to cultivate Sophora japonica seedlings. The survival rate is high, the growth is fast, the seedling quality is good and it is easy to cultivate healthy and big seedlings by grafting and seedling-raising techniques. This paper had studied several grafting propagation techniques in red-flower Sophora japonica. The result of the study is drawing the following conclusion: When scion diameter is 1.0 cm - 1.5 cm and stock diameter is less than 3 cm, the highest survival rate of cleft grafting. However, the stock diameter is than 3 cm, the higher survival rate both of tangent grafting and skin insertion grafting, and it is simple to operate, easy to know well, fast to graft and fast to grow together.
