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

Embodiment Construction

[0010] The following examples illustrate the present invention in further detail:

[0011] Rootstock cultivation period: in the rubber seed maturity season, collect fresh seeds and germinate on the sand bed for 18-22 days, select seedlings about 20-30 cm in height and in the extended leaf stage, and remove the seedlings from the sand bed. Pull up, rinse with water to remove the sand at the base and roots of the seedlings, and soak the roots of the seedlings in a container filled with shallow water to prepare for budding.

[0012] During the cultivation of mini-sprouts: first take rubber anthers as explants, add 2.4-D0.5-1mg / l, kinetin 0.5-1mg / l, naphthalene acetic acid 1-2mg / l, coconut water to MS basic medium 5%, sucrose concentration is 70-100g / l on the medium to induce callus; MS basic medium supplemented with kinetin 0.2-1mg / l, naphthaleneacetic acid 0.1-0.2mg / l, coconut water 5%, activated charcoal 1g / l, induce embryoid bodies on the medium with a sucrose concentration of 70...

Abstract

The present 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, the invention adopts anther culture combined with in vitro micropropagation technology The cultivated rubber micro-bud strips have a diameter of only 0.2 cm, small bud eyes, dense side buds, and high bud utilization. When budding, the xylem of the bud sheet does not need to be stripped off, and it is used for budding with rubber seedlings before the leaf-expansion stage as the rootstock, and the budding speed is fast. The juvenile budding tree grown by budding with this kind of bud strips grows faster , Higher output. The seedling budding method provided by the micro-bud strips of the rubber tree of the present invention is a juvenile clone cultivated by the micro-bud strips for the seedling bud-grafting, which not only achieves the purpose of shortening the cultivation period of the rubber tree bud-grafting seedlings, but also has a better effect than the existing rubber tree seedling budding. The cultivated old clone can increase the dry rubber output by 10-30%, and the growth speed can be accelerated by about 5%, and can be cut and put into production half a year earlier.

Description

Technical field [0001] The invention relates to an excellent sprout, seedling rootstock and grafting technology for cultivating rubber bud grafted trees, in particular to a seedling budding method of rubber tree miniature sprouts. Background technique [0002] In the current budding method of rubber seedlings, the cultivation of buds is carried out in the field, which requires a larger land area. In the production practice of rubber seedlings budding, the position of the bud interface is before the budding stage of the rubber seedlings. Select on the flat surface of the lower half of the hypocotyl, use a budding 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. The ion leaf at the lower end of the bud interface is about 2 cm. The skin of the abdominal sac of about 1.5-2 cm is prepared to hold the buds. The existing budding method of seedling sprouts has a large bud interface, which is not conducive to the ...
