Background
Blueberry (Vaccinium ssp. L.), also called bilberry, belongs to the genus Vaccinium (Vaccinium) of Ericaceae, and is a berry economic forest with high economic value and wide development prospect. The fruit has unique flavor, has unique efficacies of preventing cranial nerve aging, improving eyesight, resisting cancer, resisting oxidation, treating diabetes, treating cardiovascular diseases and the like, is listed as one of five kinds of human health foods by the international food and agriculture organization, and is gradually and widely applied to the fields of medicine, cosmetics, edible pigments, food processing and the like. The blueberry is a new favorite for economic fruit tree planting in China due to extremely high nutritional and health-care values.
The blueberry is introduced, planted and researched from the 80 th of the 20 th century in China, the development time is short, but with the continuous and rapid increase of the demand of the market for the blueberry in recent years, the market demand can not be met by simply depending on wild resources and existing cultivation resources, and the blueberry is introduced or the cultivation area is enlarged in many areas. Therefore, the rapid and mass supply of high-quality blueberry seedlings is one of the limiting factors for promoting the large-scale development of the domestic blueberry industrial park. The conventional blueberry propagation method comprises tissue culture propagation, cutting propagation, grafting propagation, seed propagation, layering and tillering propagation and the like. Wherein, the cutting propagation and the tissue culture propagation are two technologies which are most widely applied in production: the cutting propagation is to select partial vegetative organs of plants to be inserted into a matrix, and the regeneration capacity of the vegetative organs is utilized to take roots and branch to form new plants. However, the technology has the problems that the new seedlings continuously accumulate viruses, the properties of the viruses are gradually degraded, the viruses are influenced by environmental factors such as seasons, temperature and the like, so that the large-scale production progress of the blueberries is seriously hindered; yet another technique commonly used at present is tissue culture propagation, i.e., isolating certain tissues, organs or cells of a plant under aseptic conditions, inoculating the isolated tissues, organs or cells on a medium containing various nutrients and phytohormones, and culturing to obtain regenerated plants. The method can stably and quickly propagate the seedlings for a long time, maintain the excellent properties of the stock plant, but need to be equipped with sterilization and aseptic operation equipment and strict aseptic operation, and also need to face the problems of seedling hardening outside bottles, rooting and the like after propagation expansion, and has higher seedling threshold and cost.
Aiming at the situation of blueberry rapid propagation breeding, the inventor develops a blueberry cuttage method in a natural light microcirculation transparent incubator under the conventional (bacteria carrying) condition. The method is improved and innovated on the basis of the original conventional breeding technology, is simple and easy to implement, has low cost, obtains robust seedlings, provides an effective method for the rapid propagation and popularization of the excellent varieties of the blueberries in a large area, and also provides a reference for the rapid propagation of other similar fruit trees.

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
On one hand, referring to fig. 1, the embodiment of the invention provides a method for rapidly propagating blueberries, comprising the following steps:
s101, adding water into sphagnum moss to suck the sphagnum moss to serve as a seedling raising substrate, and sterilizing the sphagnum moss;
s102, adjusting the pH value of water of the mixed sphagnum to 4-6, enabling the sphagnum to fully absorb water and turn black, filling a seedling tray, and putting the seedling tray filled with a seedling substrate into a light-transmitting plastic incubator;
s103, transplanting blueberry tissue culture seedlings serving as initial seedlings into sphagnum which is fully expanded by water absorption in a seedling culture plate;
s104, properly adding water at the bottom of the incubator, covering and sealing the incubator, and growing in a natural light greenhouse at the temperature of 22-27 ℃;
s105, when new branches are generated in the newly transplanted tissue culture seedlings, the new branches can be promoted to grow by applying the slow-release compound granular fertilizer, and rooting powder can be dipped for promoting rooting in the cuttage process;
s106, periodically adding a certain amount of slightly acidic water with the pH value of 4-6 into the incubator;
and S107, observing that a new branch is generated and extends about 7-12 cm, and taking the new branch as the optimal source seedling for repeated cutting.
Specifically, in the embodiment of the invention, the sphagnum is added with water to be sucked and swelled through the step S101 without sterilization; the sphagnum moss is black after fully absorbing water and can be used for filling the seedling culture tray without reaching the aseptic degree, because the blueberries are difficult to root under the completely aseptic condition. The sphagnum can adopt the commonly used canadian imported sphagnum in the existing market. Through the step S102, the pH value of the water of the mixed sphagnum moss is required to be between 4 and 6 (if the natural water is alkaline, the pH value can be adjusted to be below 6 by acid or edible white vinegar), the sphagnum moss which fully absorbs the water is black, and the sphagnum moss can be used for filling a seedling tray, and the seedling tray is placed in a transparent plastic incubator; the seedling raising plate can adopt a conventional 72-hole or 32-hole seedling raising plate. The sphagnum is used as a cuttage matrix, and under the conditions of moisture, nutrients and illumination, the sphagnum and the blueberry tissue culture seedlings form an optimal ecological microcirculation system in a high-humidity environment so as to allow the blueberries to continuously and rapidly grow and repeatedly cuttage and propagate. Step S103, transplanting blueberry tissue culture seedlings serving as initial seedlings into sphagnum which is fully expanded by water absorption in a seedling culture plate; the blueberry culture seedling can be a blueberry tissue culture seedling. Because the lignification degree of the tissue culture seedling is lower, the cuttings have higher regeneration capacity; rooting and propagation of cuttings with non-tissue culture seedlings is not recommended because the regeneration capacity of non-tissue culture seedlings is extremely poor and is not sustainable. And at step S104, adding water at the bottom of the incubator, covering the incubator, sealing the incubator, and growing in a natural light greenhouse at 22-27 ℃; generally, because the incubator is difficult to install an electronic system and control temperature and light for blueberry seedling, the incubator can be placed in a greenhouse, an indoor place or an outdoor visible light place, and the temperature is preferably controlled to be 25 ℃. Thus, the culture environment of the incubator can be realized. The technology is relatively easy to realize, and the method can be finished without a complex special electronic control system. In step S105, observing that new branches are generated and extend for 7-12 cm, and then taking the new branches as the optimal source seedlings for repeated cutting; during the blueberry seedling culture period, the branches grow and root in the box all the time, and the new branches can be cut off and repeatedly cut when the new branches grow to 7-12 cm (10 cm is optimal). Therefore, continuous propagation of blueberry seedlings can be realized. In step S106, when the newly transplanted tissue culture seedling generates new shoots, the slow release compound fertilizer may be applied to promote the growth of the new shoots, and when the seedling is transplanted, rooting powder (FastRoot, Item No.1006451, Miracle Gro) may be dipped to promote rooting. A small amount of slightly acidic water (pH 4-6) is added into the box regularly, and when a tissue culture seedling is newly transplanted, a slow-release compound granular fertilizer is applied to promote the growth of new branches, and rooting powder (Fastroot, Item No.1006451, Miracle Gro company) is applied to promote rooting, so that the water and nutrients required by the growth of blueberries are ensured. Because the culture box and the inside sphagnum and blueberry seedlings form an optimal ecological microcirculation system in a high-humidity environment. Therefore, normal rooting and growth of the blueberries can be ensured only by adding a small amount of water with the pH value of 4-6 every month regularly, and the labor cost of caring such as hardening, moisturizing and frequent watering outside tissue culture seedling bottles is reduced.
The embodiment of the invention provides a method for rapidly propagating blueberries, which mainly uses transparent and sealed plastic deep boxes as containers, uses sphagnum as a cutting medium (for example, the sphagnum can adopt sphagnum imported from Canada, which is commonly used in the existing market), uses a slow-release compound granular fertilizer N-P-K (9-45-15) to promote the growth of new branches, uses rooting powder (Fastroot, Item No.1006451, Miracle Gro company) to promote the rooting, and establishes a natural light microcirculation system for the continuous rapid growth and repeated cutting propagation of blueberries. The method is suitable for blueberry tissue culture seedlings. The incubator can not control the temperature and the light of blueberry seedlings, and can be placed in a greenhouse, an indoor place or an outdoor place with visible light, and the temperature is preferably controlled to be 22-27 ℃ (25 ℃ is the best). Because the incubator is sealed, a small amount of slightly acidic moisture (pH 4-6) is added into the incubator periodically.
