Description
Technical Field
The invention belongs to the technical field of plant grafting and seedling raising, and particularly relates to a grafting method for improving grafting survival rate of litchi trees in rainy seasons and application thereof.
Background
Litchi (with the academic name: Litchi chinensis Sonn.) is originally produced in the south China and is a subtropical fruit tree, an evergreen arbor, the height of which is about 10 m, the peel of the fruit has scale-like bulges, is bright red and purplish red when the fruit is mature, and the pulp of the fruit is semitransparent, greasy, fragrant and delicious, but not durable in storage.
Litchi belongs to subtropical fruit trees, is warm in nature and evergreen, has a high common height of not more than 10 meters, sometimes can reach 15 meters or more, and has grey and black bark; small cylindrical branches, brownish red, dense white skin pores. The length of the leaf connecting stem is 10-25 cm or more; 2 or 3 pairs of small leaves, less 4 pairs, thin leathery or leathery, needle-shaped or egg-shaped needle-shaped, sometimes long ellipse-shaped needle-shaped, 6-15 cm long, 2-4cm wide, sharp top end or tail-shaped short and sharp, full edge, dark green ventral surface, luster, pink green back surface and no hair on two surfaces; the lateral pulse is usually fine and not obvious on the ventral surface and obvious or slightly convex on the dorsal surface; the petiole is 7-8 mm long.
The litchi seedlings are fruit seedlings which are directly planted and grown by litchi seeds, generally the seedlings begin to bloom and bear fruits after more than 8 years of age, but the fruit bearing is small, thin in flesh, large in kernel, sour in taste, low in yield, large in seedling size, difficult to manage, developed in root system, vigorous in vegetative growth and serious in fruiting phenomenon in the big year and the small year. The grafted litchi seedlings can bear fruits in 3 years generally, the fruits inherit the quality of high-quality litchi, and the tree shape is small and easy to manage.
The existing litchi orchard still has the defects of unreasonable variety structure, large proportion of low-market-value varieties such as 'Huai branches' and 'black leaves', over-centralized fruit maturity period and the like, so that the problems of low litchi price, low yield and low harvest and the like are increasingly highlighted. Therefore, the regulation of the variety structure of the litchi orchard by high grafting and seed changing is urgent. In addition, because the propagation coefficient of the traditional high-altitude layering seedling (also called 'circled branch seedling') seedling raising technology is too low, the seedling demand of a newly-built litchi orchard can be met only by developing the grafting seedling raising technology. Therefore, the method for grafting the litchi with high efficiency and high survival rate has important significance. The traditional litchi grafting method is that the stock part above a grafting opening is completely removed, grafting is carried out on a smooth section, then the stock and the scion are completely and hermetically wrapped by a plastic film, so that the scion is prevented from being dehydrated and dried up due to transpiration, but the traditional sealed wrapping mode also easily causes overlarge humidity inside the grafting opening and generates accumulated water, so that the scion is finally rotted and necrotic, and the grafting survival rate is low. Because the litchi is generally grafted in 2-4 months in spring and 9-10 months in autumn, the litchi planting area in the period has abundant rain and less intense sunlight, and is favorable for moisturizing the rootstock and the scion. However, by adopting the traditional grafting method, if continuous rainy weather occurs before and after grafting, soil moisture is easily saturated, and the stock can deliver a large amount of water to the scion, so that a large amount of water is accumulated in a thin film of a grafting opening, and the scion is retted, rotted and necrotized. Therefore, a new litchi grafting method is needed to be invented to solve the problem that the scion is necrotic due to the ponding water at the grafting port in the litchi grafting process, improve the grafting survival rate and expand the grafting time window.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides an inverted stock grafting method of a litchi tree, which solves the problem that a scion is necrotic due to water accumulated at a grafting opening in the grafting process of litchi and improves the grafting survival rate of the litchi in rainy seasons.
In order to achieve the purpose, the invention adopts the technical scheme that:
an inverted stock grafting method for litchi trees comprises the following steps:
s1, preparing scions: selecting an adult litchi branch as a scion, removing leaves and top tender tips of the branch, only leaving a short petiole to protect axillary buds, cutting the lower part of the axillary buds of the branch into short cut surfaces, cutting the reverse side of the short cut surfaces into long cut surfaces, and then cutting the branch into the scion from the upper part of the axillary buds;
s2, stock treatment: selecting a strong litchi seedling without diseases and insect pests and with smooth and complete bark as a stock, breaking a branch of the stock along the horizontal direction to be close to the edge of the cross section of the branch, reserving a part of xylem, and tearing off the broken branch tip and the phloem downwards for a certain distance to form an inverted stock;
s3, grafting: cutting a distance under the cambium of the opposite part of the tearing opening of the stock, aligning and tightly inserting the long cutting surface of the scion inwards with the cambium of the stock, and then totally and tightly wrapping the scion and the stock by using a film from bottom to top;
s4, post-grafting treatment: and (4) applying a medicament on the tearing opening part of the stock, and cutting off the inverted stock after the scion grows new leaves to finish grafting.
The inverted stock grafting method is adopted to graft litchi in a litchi cultivation area with clear dry seasons and clear rainy seasons, and results show that the grafting survival rate is very high in both the rainy seasons with high grafting difficulty and the dry seasons lacking rainwater. Wherein the grafting survival rate in rainy season is up to more than 98%. Therefore, the inverted stock grafting method can solve the problem that the scion is necrotic due to the ponding water at the grafting opening in the litchi grafting process, and improve the grafting survival rate of the litchi in rainy seasons.
Preferably, the litchi variety selected by the scion includes but is not limited to ' science and technology I ', ' Feizixiao ', and Fengshan red lantern '; the litchi variety selected by the rootstock comprises but is not limited to 'Feizixiao', 'Brown hairli' and 'Huai Zhi'.

Preferably, the short cutting surface is a short cutting surface with an angle of 40-50 degrees, and the long cutting surface is 2-4cm long and is cut to form a layer or a little xylem. Further, the short cutting surface is a 45-degree short cutting surface.
Preferably, in step S2, the rootstock branch is cut off along the horizontal direction, and the cut is optimally cut to one fifth of the cross section of the branch.
Preferably, the shoots are cut from 0.8-1.5cm above the axillary buds to scions. Further, the shoots were cut from 1.0cm above the axillary buds to scions.
Preferably, in the process of forming the inverted stock, the branch of the stock is cut off to one fifth of the cross section of the branch along the horizontal direction, and the branch is torn down to the position 5-8cm away from the cross section of the stock.
Preferably, 2-4cm of cambium layer opposite to the tearing opening of the stock is cut.
Preferably, when the scion and the rootstock are wrapped in a totally-enclosed manner, the axillary buds are only wrapped with a single-layer film, so that the scion and the rootstock can be conveniently germinated and tretched.
Preferably, the grafting time includes, but is not limited to, 3 months, 4 months, and 7 months. Further, grafting time is 3 months and 4 months.
For killing pests such as ants, preferably, the agent includes, but is not limited to, carbendazim and beta-cypermethrin. Further, the medicament is applied by smearing.
The invention also provides application of the inverted stock grafting method for the litchi trees in grafting and seedling raising of the litchi trees, wherein the application is to improve the grafting survival rate of the litchi trees in rainy seasons.
Compared with the prior art, the invention has the beneficial effects that:
compared with the traditional grafting method, the litchi tree inverted stock grafting method provided by the invention has the advantages that the inverted stock not only plays a role of 'pumping branches', but also is beneficial to providing water and mineral nutrient elements for the scions by the stocks; meanwhile, the inverted stock part can provide carbon nutrients such as photosynthetic assimilates and the like to the stock through the phloem, so that the activity of the stock is maintained, and the stock is prevented from shrinking and bursting skin to influence the grafting survival rate; in addition, the longitudinal section left at the grafting opening of the stock during cutting of the inverted stock is beneficial to discharging redundant water vapor and preventing accumulated water at the grafting opening from rotting, thereby improving the survival rate of litchi grafting in rainy seasons.
