Using wild jujube resources in barren hills, mantle, hills, and gully slopes, turning waste into treasure, and grafting into a variety of jujube trees on the spot is an effective method for rapid establishment of jujube economic forest. This technology is characterized by less investment, quick results, high efficiency, and easy implementation. Just entering the autumn, it is a good time for jujube grafting jujube, therefore, the masses in the mountains should fully grasp this technology.
1. Variety and scion selection should choose varieties with strong resistance to drought, drought tolerance, high yield and high quality. It is not appropriate to choose fresh food species with higher requirements for fertilizer and water; the variety should also take into account the demand for sales, High and low economic value market factors. Dried and fresh varieties include Zanhuang Dazao and Jinsixiaozao.
An annual, coarse 0.6 cm branch with a full shoot is selected for scion. The autumn joint's scion is the primary bud on the first branch of the jujube seedling. The leaves are removed immediately after harvesting, leave the petiole, and tied, and then wrapped with wet sacks to prevent loss of water, preferably with the harvesting use.
Second, rootstock processing Naturally grown on the mountain, diameter 0.8-2cm, disease-free pests, 1-3 years of wild jujube trees as rootstock, usually 2-3 m grafted a plant, a single line of land can be closer. Cut 5-10 cm from the ground, smooth the branches, cut the upper part of the rootstock, and cut out the cuts. The coarse jujube tree can be grafted on branches and one plant can be used for multiple scions.
Third, after the grafting season, according to the degree of lignification of the jujube head of the year, and the condition of rootstock and scion exfoliation, it was determined to adopt xylem buds and buds. T-shaped or I-shaped method can be used, and the survival rate is high. Buds generally do not germinate in the same year, and the buds of the buds grow properly late enough to prevent sprouting in the year.
Tools include pruning shears, hand saws, plastic strips, etc. The plastic strips are made of 0.01-0.005 mm thick plastic film and cut into 2-10 cm wide plastic strips according to the thickness of the graft.
Fourth, the method of grafting jujube date method, there are spliced, inserted skin, then the abdomen, with xylem buds and buds and then a variety of. Qiu pick more use of xylem buds and buds.
With xylem buds. Embryos adopt the main buds on the development branch of the year. During operation, the secondary branch on the scion shall be cut off by 0.7cm, and then a knife shall be cut transversely from 1cm above the main shoot to a depth of about 1/3. Then, a transverse incision shall be cut obliquely from the main shoot below 1cm and cut into The pedicel buds of the xylem are slightly above the upper flat. Then cut a "T"-shaped incision with a knife at a smooth place on the rootstock. The transverse incision is 1 cm long and the longitudinal incision is 1.5-2 cm long. Then use the tip of the incision to pry the incision of the rootstock, insert the bud, and place the upper end of the bud and the rootstock transverse incision strictly. Finally, the plastic strips are wrapped tightly from below to expose the buds. After grafting to survive, cut the anvil tip 1cm above the shoot in late March.
The buds were connected between the beginning of autumn and the summer heat. At this time, when the buds were harvested, the anvil was no longer cut. In the spring of the following year, the anvil was cut. Embryo budding uses the main bud on the unliganded jujube head. The method is to take the date of the year, cut the upper shoot 0.5cm above the main bud, and leave a short cut of 1cm on the second branch, and then cut a knife from the bottom to the top of the main bud to cut the next main bud. The single incline branches; cut the "T" shaped interface at the smooth position of the rootstock, the vertical and horizontal length of the incision is equivalent to that of the bud, deep to the xylem, and the buds will be inserted into the bevel, and the upper end of the bud is closely connected with the transverse incision of the rootstock; Only the main buds were revealed. After 1 week, the survival rate was checked by unbinding.
Fifth, after the management
1, make up. About 15 days after grafting, check whether it survives. The buds with fresh skin buds are the only ones that survive, and those with brown skin are not survived and should be patched.
2, do a good job in the tree, timely weeding, fertilization, pest control, and promote seedling growth, promote the early date, date.
