Problems solved by technology

However, the traditional high-grain grafting technology has four disadvantages. First, the sawing wound is large, and it is easy to be infected with germs; second, the top is wrapped with a film, and the moisture on the top evaporates and the humidity is high, and the newly sprouted buds on the scion are easy to rot , and it is easy to burn buds at high temperature; third, after the top film is removed, rainwater will easily flow into the grafting wound, causing the interface to rot and mold, which directly affects survival seriously; fourth, there are fewer grafted buds, and the gardening and production will be slow

Embodiment 1

[0033] In this embodiment, the "Navilina" navel orange was replaced with "Chunjian" citrus, and the 10-year-old "Navilina" navel orange tree was selected for grafting in early March in spring.

[0034] According to the spatial distribution situation of tree form, select 6 lateral branches as grafting stock;

[0035] Cut off the rootstock top diameter less than 1cm and cut off the upper branch, and then cut off the unnecessary branch group that is not selected;

[0036] Select a rootstock for grafting, start grafting from the top 5cm downwards, and then descend in turn, with an interval of 15-20cm, alternately graft left and right, and then graft the rest of the rootstocks in turn;

[0037] Immediately pour water once after grafting, and after 7 days, remove all germinated rootstock buds, and when the grafted buds germinate to a length of 0.5 cmn, use 70% imidacloprid 6000 times solution + 40% aviparinate 1500 times solution to control For aphids and red spiders, after 2 weeks...

Embodiment 2

[0040] The "Jincheng No. 100" navel orange was replaced with "See You Tomorrow" citrus, and the 12-year-old "Jincheng No. 100" navel orange tree was selected for grafting in early June in summer.

[0041] According to the spatial distribution situation of tree form, select 7 lateral branches as grafting stock;

[0042] Cut off the rootstock top diameter less than 1cm and cut off the upper branch, and then cut off the unnecessary branch group that is not selected;

[0043] Select a rootstock for grafting, start grafting from the top 5cm downwards, and then descend in turn, with an interval of 15-20cm, alternately graft left and right, and then graft the rest of the rootstocks in turn;

[0044] Immediately water once after the grafting is completed. After 7 days, all the germinated rootstock buds will be wiped off, and then wiped off once every 1 week. 300 times of % avipyridaben to control aphids and red spiders, after 2 weeks, 35% chlorantraniliprole 4000 times of liquid + 24...

Abstract

The invention discloses a top grafting, seed changing and rapid garden forming method, and belongs to the technical field of plant grafting. The top grafting, seed changing and rapid garden forming method mainly comprises the steps of stock selection, stock treatment, grafting position planning, abdomen bud grafting at the grafting position, final-period management, full utilization of small and medium branches of an original tree shape, and multi-bud grafting on each branch. According to the method, the original tree shape is utilized, the proper stock is selected for grafting, the bearing branch group is replaced, the top-grafting and seed-changing tree body is made to rapidly form a garden, meanwhile, an abdomen high-density bud grafting mode is adopted, the problems that traditional large saw bite grafting buds are prone to rot, wounds are prone to mildew, and garden forming is slow after grafting are solved, and the grafting survival rate is increased.

Description

technical field [0001] The invention belongs to the technical field of plant grafting, and in particular relates to a rapid gardening method for high grafting and plant replacement. Background technique [0002] In recent years, new varieties of citrus have emerged one after another, and the speed of updating new varieties has accelerated. In order to put the replacement varieties into production ahead of schedule, fruit farmers often adopt the traditional method of high grafting and replacement to graft in order to seize the market and obtain excess profits from new varieties. There are two main methods of traditional high grafting and replanting techniques: one is to cut off the main trunk of the tree, and then use the cutting method to graft 2-3 scions on the top of the sawn cut in the trunk, then tie the grafted joints tightly with plastic film, and then Wrap the saw cuts and scions at the top with a film to prevent the saw cuts and scions from losing water and affect s...
