High order grafting improved method of Jatropha curcas scion grafting

Abstract

The invention discloses a modified top grafting method of scion grafting of cortex jatrophae and belongs to the technology field of plant grafting. The method is preferably performed during the second third of February to the last third of March or the first third of September to October, at a mean daily temperature up to 20 DEG C plus or minus 3. A wedge-shaped grafting scion with 2-3 axillary buds is cut from a lignified or semi-lignified twig of good-quality cortex jatrophae, and the scion has a long inclined plane of 3-4cm and a short inclined plane of 2-3cm, and the two inclined planes are cut smooth and flat at the same time. A notch of 2-4cm is cut on a smooth stock and the notch is perpendicular to a part of xylem at the inner side of the cambium layer. After the sap of the scion and the stock is drained after the stock cutting, the grafting scion is inserted into the notch in a way that the cambium layers of the stock and scion are partially fitted at one side, and the grafting scion, the grafting cut and the stock cut are bound for seal, followed by timely examination and graft supplementation. After the graft survives, the bondage is removed and the stock bud is erased for several times, thereby promoting survival. The survival rate of cortex jatrophae grafted by the method is high up to over 98%.

Description

A kind of high position grafting improvement method of Jatropha curcas branch grafting technical field The invention relates to the technical field of plant grafting, in particular to a method for improving high-level grafting of Jatropha curcas branch grafting. Background technique As one of the main raw materials for biodiesel, Jatropha curcas is one of the main research crops for the development of biomass energy 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 of my country, whether it is the original forest or the 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 species without destroying the original Jatroph...
