Embodiment 1

[0010] The age of Jatropha curcas as a rootstock is 1 year, and the planting method is open-belt planting, with a width of 80 cm and a row spacing of 2.5 m × 3 m; the average ground diameter of the trees is 2.83 cm, and the average height of the trees is 87 cm. Well, no pest infestation.

[0011] The scions are collected from excellent jatropha provenances with good tree growth, no occurrence of diseases and insect pests, many branches, many strong branches, and high yield per plant.

[0012] Carry out by the step in the application content of the present invention, begin to germinate on the 4th day after sawing the anvil, contrast and begin to germinate on the 14th day after sawing the anvil, and the germination time is advanced 10 days. After budding 70 days, adopt the basal diameter of the inventive method new shoot, length and the number of leaves can reach 0.87-0.93cm, 8.5-10.5cm and 10.8-12.4 respectively, the basal diameter of contrast, length and the number of leaves a...

Embodiment 2

[0014] Follow these steps:

[0015] 1. Harvesting scions: Collect 1-year-old or 2-year-old lignified or semi-lignified Jatropha branches with full buds and no pests and diseases. After cutting, remove the leaves in time and wrap them in wet towels for later use.

[0016] 2, cutting rootstock: select the jatropha tree of diameter 1.5-3cm as rootstock, the height of the grafting position from the ground diameter is 5-20cm, vertically cut two knives from bottom to top with grafting knife at the rootstock cortex, and the top of the knife edge crosses. The length of the incision is 1.5-3cm, the width is 1.2-2.5cm, and the depth is just reaching the xylem.

[0017] 3. Cut the buds: Select the full buds in the middle or upper part of the scion and cut the buds, cut the flat surface 1-2cm above the bud eye at an angle of about 30°, control the length of the knife edge at 2-4cm, and then cut it under the bud eye Cut straight at 1-3cm perpendicular to the branch, take out the bud slice...

Embodiment 3

[0024] Follow these steps:

[0025] 1. Harvesting scions: Collect 1-year-old or 2-year-old lignified or semi-lignified Jatropha branches with full buds and no pests and diseases. After cutting, remove the leaves in time and wrap them in wet towels for later use.

[0026] 2, cutting rootstock: select the Jatropha jatropha tree of diameter 2.5-8cm as rootstock, the height of the grafting position from the ground diameter is 8-30cm, vertically cut two knives from bottom to top with grafting knife at the rootstock cortex, and the top of the knife edge intersects. The length of the incision is 2.5-5cm, the width is 2.2-3.5cm, and the depth is just reaching the xylem.

[0027] 3. Cut the buds: choose the full buds in the middle or upper part of the scion and cut the buds, cut the flat surface 1-3cm above the bud eye at an angle of about 30°, control the length of the knife edge at 3-6cm, and then cut it under the bud eye Cut straight at 1.5-3cm perpendicular to the branches, take o...

Abstract

The invention discloses a fast growing method for bud grafting of a barbadosnut, which comprises a bud grafting method and a management step after the bud grafting, wherein the bud grafting method consists of the steps of scion collecting, stock cutting, bud cutting, bud inserting and binding; and the scion collecting is to collect a branch of the annual or biennial barbadosnut with lignification, half lignification, plump eyes and no diseases and inset pests; leaves on the branch are removed in time when the branch is cut from the barbadosnut; and the branch is wrapped by a wet towel and so on for standby. The bud grafted by the method sprouts ten days earlier and grows quickly; the basic diameter, length and leaf number of a new branch by the method can improve 40.3-50 percent, 150-208.8 percent and 35 to 55 percent respectively compared with those of new branches by other methods after 70 days of the bud grafting.

Description

technical field [0001] The invention relates to a budding technique, in particular to a technique for rapid germination and rapid growth of Jatropha curcas budding. Background technique [0002] Jatropha curcas L., also known as Jatropha curcas L., is a deciduous shrub or small tree of Euphorbiaceae, 2 to 5 (or 7) meters high, Originally produced in tropical America, it is now widely distributed in tropical regions of the world. In my country, it is distributed in Yunnan, Sichuan, Guangxi, Guangdong, Hainan and other places, with the largest number in Yunnan Province, followed by Sichuan Province. It is often concentrated on river banks, houses, and roadsides; The stems and leaves are poisonous and are not eaten by livestock. They are often cultivated as hedgerows and used as "biological fences" for vegetable fields and farmland. Jatropha curcas is suitable for a wide range of growth. It can grow normally in the south where the altitude is below 1600 meters and the annual ave...
