Seedling budding method for rubber tree minitype bud sticks

Abstract

The present invention relates to a technology for cultivating the excellent bud stick, the seedling root stock and a grafting technique of the grafted rubber tree, in particular to a seedling grafting method for the micro-bud stick of the rubber tree. The diameter of the rubber micro bud stick cultivated by the present invention through the cultivation of the flower medicine combined with an isolated micro-breeding technique is only 0.2 cm; the sprout eye is small; the side sprout is concentrated and the utilization rate of the sprout is high. When in grafting, the wooden part of the sprout does not need to be stripped; the grafting performed by the sprout with the root stock of the rubber seedling before the leaf-expansion period has a rapid speed; adopting the bud stick grafting can cultivate a young grafted tree that can grow much faster and has higher yield. The grafted tree cultivated by the micro bud stick provided by the seedling grafting method of the rubber tree micro bud stick of the present invention through the seedling grafting is the juvenile-type clone, which not only realizes the object of shortening the cultivation period of the rubber tree grafting seedling, but also improves the yield of the dry glue about ten to thirty percent, accelerates the growth about five percent and can be cut down to be put into production half a year in advance compared to the old clone cultivated by the prior rubber tree seedling grafting.

Description

technical field [0001] The invention relates to an excellent bud strip for cultivating rubber bud grafting trees, seedling rootstock and grafting technology thereof, in particular to a method for seedling bud grafting of rubber tree micro-bud strips. Background technique [0002] At present, in the budding method of rubber tree seedlings, the cultivation of bud strips is carried out in the field, which requires a large land area. In the production practice of budding rubber tree seedlings, before the rubber tree seedlings are in the stage of the first true leaf development, the position of the bud interface Choose on the flat surface of the lower half of the hypocotyl, use a bud grafting knife or a scalpel to open a bud interface with a width of about 1 / 2 of the stem circumference and a length of about 3-4 cm, and the lower end of the bud interface is about 2 cm. About 1.5-2 centimeters of abdominal sac skin, in order to clamp the bud sheet, the bud interface opened by the s...

Problems solved by technology

Since the buds and rootstocks are not commensurate, the diameter of the seedling stock is about 0.3 cm, and the diameter of the buds is 0.5 to 1.2 cm. Take the buds from the 0.5 to 1.2 cm diameter buds and connect them to the seedlings with a diameter of about 0.3 cm. , a skilled worker can bud about 120 plants a day, and there are many inconvenient problems such as taking buds and repairing buds during the budding operation
