Description

Technical Field

[0001] The invention belongs to the technical field of seedling raising devices, and in particular relates to a transplantable seedling raising device for dahlia breeding. Background Art

[0002] Dahlia (Dahlia pinnata. Cav) is a bulbous plant of the genus Dahlia in the Asteraceae family. It has other names such as radish flower, dahlia, passion flower, sweet potato flower, dahlia, and dahlia. Dahlia is one of the flowers with the most varieties in the world. It has rich colors, including seven major colors of red, yellow, white, pink, purple, black, and complex colors. It has various flower shapes, including decorative type, chrysanthemum type, cactus type, and laurel type. It has a long flowering period and has extremely high ornamental value. It is used in landscaping at home and abroad. Dahlias have colorful colors and various shapes. Different varieties have different plant heights. The tall varieties can reach 2m, and the short varieties are less than 50cm. They can be matched according to different heights to make flower borders, or they can be placed in pots. Dahlias are suitable for flower beds, flower borders, or clusters in front of the courtyard. Dwarf varieties can be used as potted plants. Potted planting is an important form of dahlia cultivation. It is not only conducive to meeting the needs of dahlia commercialization, but also convenient to use and fast seedling growth. It is especially suitable for festival display to set off the atmosphere and beautify the environment. The traditional breeding methods of dahlias include division, cutting and sowing.

[0003] Among them, dahlia division and cutting propagation belong to vegetative propagation, which can maintain the excellent characteristics of dahlias and can bloom early, but the bulb preservation is cumbersome and the reproduction coefficient is low. Dahlia sowing propagation is affected by the characteristics of the variety. Only single-petal varieties can bear fruit. Most varieties are not self-fertile. Seedlings have strong vitality, strong adaptability, and high reproduction coefficients, but they cannot maintain the excellent characteristics of the mother plant and are prone to degeneration and separation, which affects the seedling cultivation and reproduction of dahlias.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0024] Reinforcing plates 11 are fixed to the top ends of the two long axis sides of the cultivation trough body 1, and a plurality of support rods 12 are fixed at equal intervals between the two reinforcing plates 11. Three connecting seats 13 are fixed to the top surface of each support rod 12 at equal intervals. A group of seedling racks 2 is connected between two adjacent support rods 12 via the connecting seats 13. The length of the cultivation trough body 1 corresponds to the number of groups of the seedling racks 2. At least three groups of seedling racks 2 can be used for synchronous cultivation in a single cultivation trough body 1, which improves the seedling cultivation efficiency of dahlias and can further improve the breeding efficiency of dahlias.

[0025] The seedling raising racks 2 are arranged in groups of three, and a seedling raising bag 3 is fixed in each of the seedling raising racks 2. The seedling raising bag 3 is used to cultivate dahlia seedlings.

[0026] Among them, the seedling frame 2 is composed of a square frame 21, a connecting rod 22 and a connecting sleeve 23. The connecting rods 22 are vertically fixed at the centers of the two short axis sides of the square frame 21. The connecting rods 22 are square hollow rods. A square through connecting hole is arranged in the connecting seat 13. The connecting rods 22 are used in conjunction with the square through connecting hole. Connecting sleeves 23 are respectively fixed near the four end corners on the square frame 21. The connecting sleeves 23 are arranged at positions near the four end corners on the square frame 21 to open the opening of the seedling bag 3 to the maximum extent. When the connecting sleeve 23 is connected to the seedling bag 3, the opening of the seedling bag 3 can be stretched to the maximum value, thereby avoiding the bag opening of the seedling bag 3 from affecting the growth of the seedlings during the dahlia cultivation process, thereby improving the seedling cultivation efficiency.

[0027] The seedling bag 3 includes a top connecting ring 31, side meshes 32, a middle mesh 33 and a connecting rope 34.

[0028] The mesh diameters of the side mesh 32 and the middle mesh 33 are smaller than the minimum particle size of the seedling medium, which can prevent the seedling medium in the seedling bag 3 from falling into the cultivation tank 1, avoid damage to the dahlia root system during the later transplanting process, and improve the survival rate of transplanting.

[0029] The side mesh 32 and the middle mesh 33 are both made of degradable materials, and the degradation time of the degradable materials is longer than the time of a single dahlia seedling cultivation. That is, in the early stage of dahlia seedling cultivation and transplanting, the side mesh 32 and the middle mesh 33 can form protection at the root system of the dahlia seedlings. After the dahlia is transplanted, the side mesh 32 and the middle mesh 33 are degraded, thereby avoiding squeezing the root system growth of the dahlia in the later stage, reducing manual intervention, and being convenient and practical.

[0030] The seedling bag 3 and the cultivation trough 1 are both filled with seedling matrix, in which the sucrose level is 20 g / L, the agar level is 4 / L, and the NAA is 1 mg / L. At the same time, a matrix mixture of peat: fine sand: vermiculite in a ratio of 1:2:3 is used. When in use, under a natural state, the height of the seedling matrix in the seedling belt 3 is not less than the height of the seedling matrix in the cultivation trough 1.

[0031] An arc frame 4 is clamped between the two reinforcing plates 11 in the middle above the same group of seedling racks 2. The arc frame 4 consists of an arc outer rod 41 and an arc inner rail 42. The two bottom ends of the arc outer rod 41 are respectively clamped on the corresponding reinforcing plates 11. A greenhouse film is arranged on the outside of the arc outer rod 41 to maintain the stability of the temperature and humidity in the culture tank body 1.

[0032] The arc-shaped inner rail 42 is fixed on the inner side of the arc-shaped outer rod 41, and an auxiliary seedling-raising seat 5 is movably connected inside the arc-shaped inner rail 42, through which supplementary light and water spraying can be performed during the seedling-raising process.

[0033] The auxiliary seedling raising seat 5 includes an outer seat body 51, an active driving wheel 52, an auxiliary wheel 53 and a through hole 54. The outer seat body 51 is connected to an active driving wheel 52 near the top, the active driving wheel 52 is driven by a motor, and the active driving wheel 52 abuts against the inner side of the arc-shaped inner rail 42. The outer seat body 51 is also rotatably connected to the two sides respectively, and the auxiliary wheels 53 abut against the outer side of the arc-shaped inner rail 42. The outer seat body 51 is movably connected to the arc-shaped inner rail 42 through the cooperation of an active driving wheel 52 and two auxiliary wheels 53. A through hole 54 is also opened on the outer seat body 51 near the bottom, and a counterweight seat 6 is movably connected in the through hole 54.

[0035] A fill light and two sprinkler heads are provided on the bottom surface of the seedling auxiliary plate 61. The fill light is an LED fill light, and the vertical fill light irradiation area of ​​the fill light is smaller than the top cross-sectional area of ​​the seedling rack 2. Therefore, during use, before fill light, the auxiliary seedling seat 5 is used to drive the fill light to move to the top of the seedling rack 2 that needs fill light, and then the fill light is turned on for precise directional fill light, so that precise directional fill light operation can be performed on the three seedling racks 2 in the same group, avoiding the occurrence of blind spots caused by local excessive fill light, thereby improving the seedling raising efficiency.

[0036] The spray head is connected to the water tank through a water pipe. Similarly, according to the growth situation of the dahlia seedlings, before spraying and watering, the auxiliary seedling seat 5 is used to drive the spray head to move to the top of the seedling rack 2 where water needs to be supplemented, and then the spray head is started to spray and water. This can avoid the dahlia seedlings in the seedling rack 2 from being oversaturated or lacking water, accurately perform watering operations, improve the efficiency of seedling cultivation, and be convenient and practical.
