The invention belongs to the technical field of golden locust breeding, in particular to a method for cutting seedlings of golden locust. Aiming at the problems of long time-consuming, high cost and low survival rate of grafted seedling of Sophora japonica, the present invention provides a method of cutting seedling raising of Sophora japonica, which includes the following steps: A. leveling the cutting seedbed, preparing nutrient soil, covering the nutrient soil on the cutting seedbed, forming a cutting matrix; B. selecting the branches of Sophora japonica japonica and cutting 10-12 cm growth. After sterilization, the cuttings were dipped in IAA solution of 800-1200 ppm for 2-3 seconds, then the cuttings were placed on the substrates and watered after cuttings. C. The air temperature was controlled at 18-25 C, and the air humidity was 40-60%. Within 40-50 days of cuttings, the humidity of the substrates was controlled at 70-75%, and after 40-50 days of cuttings, the humidity of the substrates was controlled at 55-65%. . The method of the invention improves the survival rate of Cuttage of Robinia pseudoacacia from 5% to about 80%, reduces the seedling raising time, saves the production cost, provides the basis for Cutting and seedling raising of Robinia 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的小斜面。在国槐截干处,选平滑顺直的地方,将国槐皮层垂直切一小口,长度为接穗长削面的1/2~2/3,把接穗沿切口木质部与韧皮部中间插入,长削面朝木质部,并使接穗背面对准切口正中,削面“留白”0.3~0.4cm,根据国槐粗度可接2~3个接穗,并均匀分布,接穗接好后,用宽5cm左右的塑料布,将伤口绑严即可。芽接则采用根际芽接,剪取金槐一年生枝条做接穗,除去复叶后备用;从接穗枝条芽的上方1~1.5cm处下刀,稍带木质部直向下平 ...
