Description

Technical Field

[0001] The utility model belongs to the technical field of seedling cultivation, and specifically relates to a seedling cultivation device, and in particular to a device for cultivating oil-tea camellia seedling rootstocks. Background Art

[0002] Camellia oleifera (Came lliaolei fera Abel) is a native Chinese tree species. It is an evergreen small tree or large shrub of the Theaceae family, growing to over 100 years old and reaching a height of 2 to 8 meters. Its seeds contain 20% to 35% oil, rich in nutritional value. For this reason, it is known as the "green oil depot" and is an essential edible oil in our daily lives. Camellia oil boasts a bright color, a mellow flavor, and a pleasant taste. It is also highly nutritious and has excellent therapeutic effects on arteriosclerosis, cardiovascular and cerebrovascular diseases, chronic pharyngitis, and hypertension. It is also an important raw material in industry, national defense, and medicine, enjoying broad market prospects and great potential for development.

[0003] Camellia oleifera, a traditional woody oil-bearing crop in my country, not only carries rich ecological value, but is also an important way for farmers in mountainous areas to increase their income and become rich. With the continuous growth of market demand, the low yield and low efficiency of traditional camellia oleifera cultivation methods have become increasingly prominent, and there is an urgent need to improve the yield and quality of camellia oleifera through technological innovation. Grafting propagation technology has become a key means to improve the efficiency of camellia oleifera variety improvement because it can effectively combine the stress resistance of the rootstock with the excellent traits of the scion. Bud rootstock grafting seedling cultivation, as an efficient and rapid asexual propagation method, can shorten the breeding cycle and accelerate the promotion of improved varieties. It is of great significance to improving the overall benefits of the camellia oleifera cultivation industry.

[0004] Before transplanting Camellia oleifera rootstock grafted seedlings from the nursery bed to the field, using container bags and seedling trays to raise them as container seedlings effectively ensures the survival rate and quality of the seedlings after transplanting. However, existing seedling trays have the problem of excessive water accumulation at the root of the seedlings, which can easily damage the growth of the seedlings. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a device for cultivating oil tea seedling rootstocks, so as to solve the problem that the existing seedling trays are damaged by excessive water accumulation at the roots of the seedling rootstocks.

[0006] In order to achieve the above technical objectives, the utility model provides the following technical solutions: a device for cultivating oil tea seedling stock, comprising a chassis, the top of the chassis is open, the chassis is detachably connected to a tray, notches are provided on both sides of the top of the chassis, both sides of the tray are fixedly connected with fixed blocks that can pass through the notches, the bottom side of the fixed block is connected with a connecting block, the connecting block and the fixed block are L-shaped, and a holding groove in the chassis is formed between the connecting block, the fixing block and the outer wall of the tray, the inner cavity of the tray is fixedly connected with longitudinal partitions and transverse partitions that cross each other horizontally and vertically, the longitudinal partition and transverse partition brackets enclose a planting bag support hole, and the bottom inner wall of the planting bag support hole is provided with a drainage hole.

[0007] It should be noted that container seedling cultivation for oil tea seedlings (Camellia oleifera) using rootstock grafting combines grafting with container seedling cultivation. This method boasts a well-developed root system, high survival rate, excellent growth, and the preservation of superior clonal characteristics. It is currently an effective means of cultivating high-quality oil tea seedlings on a large scale, enabling the production of large quantities of high-quality seedlings. In particular, improved seed storage and germination methods, including the innovative integrated storage and germination method, eliminate multiple steps such as seed removal and sand screening, reducing production costs, increasing seed germination rates and the rate of strong rootstock buds. This facilitates rapid healing of grafting wounds, significantly improving graft survival rates, and cultivating high-quality seedlings that meet afforestation requirements. Pre-grafting preparations must be thorough; during grafting, all steps must be coordinated and key technical points must be carefully controlled. Post-grafting, management measures must be maintained throughout the seedling stage, including water, temperature, fertilizer, pest and disease control, germination, and wind and frost protection.

[0008] Further preferably, the top heights of the transverse partitions and the longitudinal partitions are both lower than the top horizontal plane height of the tray.

[0009] Further preferably, an overflow port is provided on the inner side wall of the planting bag support hole.

[0010] Further preferably, the front inner wall and the rear inner wall of the tray are provided with strip grooves located above the transverse partitions and the longitudinal partitions, and the front inner wall and the rear inner wall of the chassis are provided with grooves matching the strip grooves.

[0011] Further preferably, a collection cavity is formed between the tray and the bottom inner wall of the chassis, and a drainage pipe communicating with the collection cavity is opened on one side of the chassis.

[0012] Further preferably, the four corners of the bottom of the chassis are fixedly connected with support blocks.

[0013] Compared with the prior art, the present invention provides a device for cultivating oil-tea camellia seedlings, which has the following beneficial effects:

[0014] (1) The device inserts a camellia oil seedling rootstock planting bag into the supporting hole of the planting bag. When watering, the drainage holes opened on the inner wall of the bottom of the supporting hole of the planting bag facilitate the discharge of water, thereby preventing the growth of the camellia oil seedling rootstock from being damaged due to siltation in the supporting hole of the planting bag.

[0015] (2) The device facilitates lifting the tray and separating it from the base by lifting the two connecting blocks, making it easier to take the tray, thereby reducing the workload of seedling cultivation and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4The utility model discloses a device for cultivating oil-tea camellia seedlings, comprising a chassis 1, the top of the chassis 1 being open, the chassis 1 being detachably connected to a tray 2, notches 3 being provided on both sides of the top of the chassis 1, fixed blocks 4 that can pass through the notches 3 being fixedly connected on both sides of the tray 2, a connecting block 5 being connected to one side of the bottom of the fixing block 4, an L-shape being formed between the connecting block 5, the fixing block 4 and the outer wall of the tray 2, a holding groove 6 being clamped in the chassis 1 being formed, the inner cavity of the tray 2 being fixedly connected to longitudinal partitions 7 and transverse partitions 8 that intersect in the horizontal and vertical directions, the longitudinal partitions 7 and transverse partitions 8 being bracketed to form a planting bag support hole 9, a drainage hole 11 being provided on the bottom inner wall of the planting bag support hole 9. After the oil-tea camellia seedling planting bag is inserted into the planting bag support hole 9, the drainage hole 11 provided on the bottom inner wall of the planting bag support hole 9 is conducive to the discharge of water when watering, thereby avoiding the influence of silt in the planting bag support hole 9 on the growth of the oil-tea camellia seedlings. In addition, by lifting the two connecting blocks 5, the tray 2 can be easily lifted and separated from the chassis 1, making it easier to take the tray 2.

[0023] The main body of the tray 2 is located in the inner cavity of the chassis 1. By placing a finger under the connecting block 5 and lifting the connecting block 5 upward, the tray 2 can be easily detached from the chassis 1. The tray 2 is provided with a plurality of planting bag support holes 9 for inserting the oil tea seedling stock planting bags, which improves the overall handling efficiency compared to the presence of separate planting bags.

[0024] The planting bag support hole 9 is used to place the oil tea seedling stock planting bag, and the oil tea seedling stock planting bag is made of non-woven fabric. In addition, the top heights of the transverse partitions 8 and the longitudinal partitions 7 are both lower than the top horizontal plane height of the tray 2. Specifically, an overflow port 10 is provided on the side inner wall of the planting bag support hole 9. In this embodiment, the overflow port 10 is provided on the longitudinal partitions 7 and the transverse partitions 8 that enclose the planting bag support hole 9. When the tray 2 is watered, the water in one planting bag support hole 9 whose water level is higher than the overflow port 10 can overflow to another adjacent planting bag support hole 9.

[0025] Specifically, the front and rear inner walls of the tray 2 are each provided with grooves 12 located above the transverse partitions 8 and the longitudinal partitions 7. The front and rear inner walls of the chassis 1 are each provided with grooves 13 that cooperate with the grooves 12. In this embodiment, the grooves 13 cooperate with the grooves 12. When excessive water is poured into the tray 2 and the water level in the tray 2 is higher than the grooves 12, the excess water can overflow from the grooves 12 into the grooves 13.

[0026] Specifically, a collection chamber 14 is formed between the tray 2 and the bottom inner wall of the chassis 1. A drainage pipe 16 is provided on one side of the chassis 1, communicating with the collection chamber 14. The drainage pipe 16 is used to drain water from the collection chamber 14 and can be threadedly connected to a plug. In this embodiment, when water is applied to the oil-tea camellia seedling stock planting bag within the planting bag support hole 9, the water can seep into the collection chamber 14 through the drainage hole 11, preventing water from accumulating within the planting bag support hole 9 and affecting the oil-tea camellia seedling stock.

[0027] Specifically, the four corners of the bottom of the chassis 1 are fixedly connected with support blocks 15. In this embodiment, the support blocks 15 are used to raise the bottom height of the chassis 1.

[0028] The steps of using the device of the utility model to carry out oil-tea camellia seedling rootstock seedling cultivation are:

[0029] (1) Seed collection and storage: After harvesting the oil tea, select mature and plump oil tea fruits and sun-dry them for 2 days. Then, dry them in the shade to remove the oil tea seeds. Then, select the complete oil tea seeds with full grains and no pests and diseases as seeds. You can choose to store them in layers of sand or pack them in sacks and store them in a cold storage environment at 0-5℃. Avoid seeds from getting moldy or being eaten by insects and rodents.

[0030] (2) Bagging: Before grafting, prepare a light matrix and bag it. The main components and proportions of the light matrix are: 50% peat soil, 30% perlite, 10% rice, and 10% grass. The size of the nutrient bag is 6 cm in diameter and 8 cm in height or 5.5 cm in diameter and 10 cm in height.

[0031] (3) Build a sunshade: Before grafting begins, build a sunshade. The height of the sunshade is generally 2-2.3m, and the shading rate is about 75%-80%. Tie it tightly.

[0032] (4) Seed germination: In March, remove the film from the sand bed and spray the sand bed with a 0.15% solution of carbendazim or thiophanate-methyl in clean water. Water thoroughly once to increase the humidity of the sand bed and disinfect it. Cover the bed with film again and remove the top layer of straw to increase the temperature. Water the bed every 4-5 days to maintain a certain humidity. The integrated storage and germination method can eliminate the steps of seed removal, sand screening, seed washing, seed soaking, and re-sowing, reducing production costs and increasing the seed germination rate and the rate of strong buds on the rootstock.

[0033] (5) Management of bud and rootstock seedlings: During the bud and rootstock development period, water the buds regularly to ensure adequate moisture for bud development. By mid-to-late April, the bud and rootstock growth is regulated mainly by controlling the temperature and humidity of the sand bed, based on the germination of the seeds and the growth of the scion. Generally, the stems can be used for grafting when they grow to 3-5 cm in height.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
