Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, in particular to a raspberry seed seedling cultivation method. Background Art

[0002] Raspberry (Rubus corchorifolius LF), also known as blackberry, is a composite berry of the genus Rubus (Rubus. L) of the Rosaceae family (Rosaceae). Due to its rich nutrients and medicinal value, it is recommended by the Food and Agriculture Organization (FAO) as a "third-generation fruit tree".

[0003] The "Guizhou Berry No. 1" variety is a new raspberry variety cultivated by the applicant in recent years. It belongs to the red bubble vine. Compared with other raspberry varieties, its botanical characteristics are that there are no thorns on the branches and leaf axes. It is a new variety suitable for picking experience.

[0004] Since the raspberry seeds of this variety are small, the seed coat is hard and has a waxy layer, and the dormancy time is long, it is difficult to germinate and has a low germination rate. At present, the tissue culture and layering methods are mainly used to quickly obtain seedlings for this variety. However, the tissue culture seedling cycle is long and the cost is high, and the layering propagation coefficient is small and the rooting time is long. The present invention adopts seed direct seeding to quickly cultivate the "Qianmei No. 1" raspberry seedlings to meet the planting needs. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a method for raising raspberry seed seedlings, which ensures the planting quality of seedlings through precise control. The specific technical scheme is as follows: A method for raising raspberry seeds, comprising the following steps: Step 1: Seed collection: Every summer, harvest healthy, disease-free "Qianmei No. 1" fruits, wash the pulp, and take out the seeds. Select a number of seeds that are not shriveled, soak them in white vinegar for 24 hours, then rinse them with clean water to wash off the wax layer on the surface of the seeds, put them in the sun for 3 hours on a sunny day, and then move them to a cool and dry place to dry naturally for storage.

[0006] Step 2: Pre-sowing treatment: Every autumn, take the dried "Guizhou Berry No. 1" raspberry seeds, soak them in 40-60 degrees Celsius warm water for another 12 hours, drain the water, add white vinegar to cover the surface of the seeds. If the seeds cannot be completely immersed in white vinegar due to their density, add an appropriate amount of water. After 24 hours, drain the water and you can sow them.

[0007] Step 3: Substrate preparation: Select clean river sand without impurities, put it into 8*10 non-woven nutrient bags, and place them neatly on a flat plot with clean water source.

[0008] Step 4: Sowing: According to the size of the nutrient bag, take a small amount of seeds (about 30-50 seeds) and sow the processed seeds on the surface of the nutrient bag, and cover the seeds completely with a thin layer of fine river sand.

[0009] Step 5: Post-sowing management: After sowing, build a shade net according to the size of the seedbed to make the shading degree reach more than 80%. Spray and water the seeds once every evening before germination. After emergence, water them according to the drought layer of the seedlings. The seedlings will emerge in 50-60 days, and the emergence rate can reach more than 90%.

[0010] Effects of the present invention: The raspberries cultivated by the invention have high emergence rate, few diseases, fast growth of branches and leaves, high survival rate of raspberries after transplanting, and good environmental resistance. Moreover, the invention uses common raw materials, is simple to operate, and is suitable for large-scale factory seedling cultivation. BRIEF DESCRIPTION OF THE DRAWINGS

In large-scale seedling cultivation, the seedlings emerge in an orderly manner and the emergence rate is high; Figure 2 This is a close-up picture of the raspberry seedling cultivation of the present invention. It can be seen that the leaves of the seedlings emerging from the nutrient bag are huge and the branches and leaves are thick. DETAILED DESCRIPTION
