Embodiment 1

[0016] The excellent Jatropha curcas material used in this test belongs to the geographically dominant species after multiple reselections, and the target character is stable, that is, the oil content of the seed kernel is 65.5%, and the yield per mu is 350kg (20 plants per mu).

[0017] Follow the steps below

[0018] 1. Budding time and scion selection

[0019] Choose to bud in February in spring and September in autumn. The scion adopts the lignified and semi-lignified branches of Jatropha curcas with excellent materials, and the rootstock selects the Jatropha curcas that needs to be transformed. The daily temperature for budding is 20±3°C.

[0020] 2. Budding operation

[0021] (1) Bud peeling: select the spikes of a good Jatropha curcas variety, and use a grafting knife to peel off the buds. When taking buds, use a grafting knife to cut horizontally at 1.0-1.5 cm above and below the bud position, press and cut to the xylem at the left and right sides of the buds at a ...

Abstract

The invention discloses a modified top grafting method for bud grafting of cortex jatrophae and belongs to the technology field of plant grafting. The method comprises the steps of selection of bud grafting time and scionwood, bud grafting operation and post-bud grafting management. The bud grafting is performed during the second third of February to the last third of March or the first third of September to October. A grafting bud of 2.0-3.0cm length and 0.8-1.2cm width is cut from a lignified or semi-lignified twig of good-quality cortex jatrophae by using a grafting knife. A graft interface is formed on a root stock and has the same size as the bud piece. The interface should be cut through the cortex and deep into the xylem. The bud piece is grafted after saps of the grafting bud and the root stock are drained, about 10 minutes after root stock cutting. The grafting bud is inserted into the interface and sealed by binding, followed by timely examination and graft supplementation. After the graft survives, the bondage is removed, the stock bud is erased, and the stock pile above the interface is sheared off, thereby promoting the survival. The method has the advantages of short time, rapid action and high survival rate of grafted bud (above 96%).

Description

technical field [0001] The invention relates to the technical field of plant grafting, in particular to a method for improving high-level grafting of jatropha curcas budding. Background technique [0002] Jatropha curcas is an important tree species for the development of biomass energy (biodiesel) industry in my country. The current Jatropha patents involve extracts, biodiesel preparation, breeding and cultivation, and so on. Jatropha curcas has begun to take shape in the western region, whether it is primary forest or new forest. However, as an intensive and large-scale raw material production, improving the quality and output of forest land will be one of the key directions for future research on Jatropha curcas. Grafting, as an effective technique for species improvement, can replace good varieties without destroying the original Jatropha curcas forest land, shorten the improvement time, and improve forest land benefits. [0003] At present, grafting technology is wid...
