The invention belongs to the technical field of the propagation of Sophora japonica, in particular to a method for raising seedlings by cutting with ground heating. Aiming at the problem that the existing seedlings of Chinese locust are susceptible to seasonal influence and can not be cut on a large scale all year round, the present invention provides a method of raising seedlings of Chinese locust by ground heating, which includes the following steps: A. leveling the cutting bed, laying the ground heating facilities; B. preparing nutrient soil to form cutting matrix; C. selecting Chinese locust branches to eliminate. After poisoning, they were dipped in IAA solution for 2-3 seconds and cut on the substrate. D. A small arch shed was added to the cutting seedbed to cover the white plastic film and shading net. E. Air temperature, air humidity and matrix temperature and matrix humidity were controlled after cutting. The method of the invention can raise the survival rate of Cutting of Amorpha pseudoacacia to about 95%, solve the problem of temperature restriction in Cutting seedling raising, provide the basis for large-scale production and seedling raising of Amorpha pseudoacacia, and has important significance.

技术介绍
金槐树学名金枝槐,拉丁文名为(Sophorajaponicacv.GoldenStem),别名金枝国槐等。金槐是蔷薇目豆科槐属落叶乔木,属于国槐的变种之一,树茎、枝为金黄色,特别是在冬季,这种金黄色更浓、更加艳丽,独具风格,颇富园林木本花卉之风采,具有很高的观赏价值。是园林绿化中常用树种之一。金槐不仅具有观赏价值,其叶、花中还富含芦丁等成分,用途广泛。现有的金槐种植主要分布在广西、云南、四川等地,种植量不大。这主要是受到金槐繁殖方法复杂、成活率不高的限制。现有的金槐育苗方法只要采用嫁接,以国槐为砧木进行枝接或芽接。枝接采用插皮接,在嫁接前,选择生长充实,无病虫害,直径1cm左右的一年生枝条做接穗,短截成10cm左右蜡封,以防止水分损失,然后沙藏于阴凉背风处备用,4月中下旬,待国槐发芽后,选择横径3cm以上、树干较直的国槐大苗,在适当位置截干后嫁接。先将接穗下端芽背面削成长3~5cm的削面,削面要平直并超过髓心,再将长削面背面末端削成0.5~0.8cm ...
