Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of forestry seedling cultivation, and particularly relates to a seedling cultivation device and a seedling cultivation method for forestry engineering afforestation. Background Art
[0002] Afforestation can keep water and soil. Where the vegetation coverage rate is low, rain is likely to cause soil erosion, damage fields, raise river beds, and easily cause flood disasters. Very young seedlings cannot be directly planted outdoors because they are small and the outdoor environment is not good, making it difficult for them to survive. Therefore, seedlings need to be cultivated to a certain height before being transplanted outdoors for planting.
[0003] In the traditional seedling cultivation process of forestry engineering, the sprinkler self-spraying device is a common irrigation method. This device sprays water to the roots and leaves of seedlings by installing sprinklers on the seedling bed and using a water pump to pressurize the water source to provide them with necessary moisture. However, with this spraying method, the nutrient solution only acts on the surface soil, making it difficult to form deep penetration, resulting in the phenomenon of "shallow roots" where the roots grow upwards due to water tropism, and the metabolic waste liquid accumulates at the bottom of the basin, causing salt accumulation. Therefore, it is necessary to propose a seedling cultivation device and a seedling cultivation method for forestry engineering afforestation. Summary of the Invention
[0004] The purpose of the present invention is to solve the deficiencies in the prior art that in the traditional method, it is necessary to manually mix water, nutrient solution, and medicinal liquid frequently, resulting in a large labor intensity and difficult to ensure the mixing uniformity during large-scale operations. With the spraying method, the nutrient solution only acts on the surface soil, making it difficult to form deep penetration, leading to the phenomenon of "shallow roots" where the roots grow upwards due to water tropism, and the metabolic waste liquid accumulates at the bottom of the basin, causing salt accumulation. A seedling cultivation device and a seedling cultivation method for forestry engineering afforestation are proposed.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A seedling-raising device for forestry engineering afforestation, comprising a seedling-raising box and a bottom plate. The seedling-raising box and the bottom plate are fixedly connected. An infusion rod is fixedly connected inside the seedling-raising box. Seedling-raising cans are symmetrically and fixedly connected to the outside of the infusion rod. A spiral penetration ventilation seedling-raising component is jointly arranged on the infusion rod and the seedling-raising cans. The spiral penetration ventilation seedling-raising component includes an infusion groove movably connected to the infusion rod, a spiral infusion pipe arranged inside the seedling-raising can, and an annular partition arranged inside the seedling-raising can. A push plate is movably connected inside the annular partition. A plurality of tooth blocks are movably connected to the side of the push plate close to the bottom plate. A servo motor is movably connected to the side of the bottom plate close to the seedling-raising box. A plurality of gears are arranged on the servo motor. The infusion groove and the spiral infusion pipe are in communication. Nutrient solution flows from the inside of the infusion groove into the inside of the spiral infusion pipe. There are a plurality of ventilation holes between the spiral infusion pipe and the annular partition. The start of the servo motor will drive the gears to rotate. The rotation of the gears will drive the tooth blocks to move back and forth in the vertical direction. The movement of the tooth blocks will push the push plate to move back and forth in the vertical direction. A drain pipe is movably connected to the lower part of the seedling-raising can.
[0007] The above technical solution further includes:
[0008] An infusion rod and a liquid inlet pipe are fixedly connected inside the infusion rod. The infusion rod and the liquid inlet pipe are fixedly connected. The infusion rod and the seedling-raising cans are jointly in communication with the infusion groove. Nutrient solution will flow into the inside of the infusion rod through the liquid inlet pipe.
[0009] The number of the seedling-raising cans is multiple groups. The multiple groups of seedling-raising cans are linearly and evenly distributed along the infusion rod. The inside of the seedling-raising can is fixedly connected to the spiral infusion pipe. The spiral infusion pipe is in communication with the infusion groove. Nutrient solution will flow from the inside of the infusion groove into the inside of the spiral infusion pipe to provide nutrients for the saplings.
[0010] The inside of the seedling-raising can is fixedly connected to the annular partition. A plurality of ventilation holes are opened on the outside of the annular partition. The multiple groups of ventilation holes are evenly distributed in a circular pattern along the annular partition. The size of the ventilation holes is adapted to the size of the spiral infusion pipe. The ventilation holes on the outside of the annular partition can prevent the spiral infusion pipe from being blocked by soil.
[0011] A plurality of penetration holes are opened on the inside of the push plate. The multiple groups of penetration holes are evenly distributed in a circular pattern along the push plate. A vertical plate is fixedly connected to the lower part of the push plate. A connecting plate is slidably arranged on the outside of the vertical plate. The connecting plate is fixedly connected to the seedling-raising can. The back-and-forth movement of the vertical plate will drive the push plate to move in the vertical direction.
[0012] The outside of the vertical plate is fixedly connected to a plurality of tooth blocks. The multiple tooth blocks are linearly and evenly distributed along the vertical plate. The movement of the tooth blocks will drive the vertical plate to move back and forth in the vertical direction.
[0013] An inner side of the seedling-raising box is provided with a placement groove, and a first support plate is fixedly connected to an inner bottom of the placement groove. One end of the first support plate away from the placement groove is fixedly connected to a servo motor. The function of the first support plate is to connect the placement groove and the servo motor.

[0015] Lower portions of a plurality of the connecting plates are all fixedly connected to connecting pipes. One ends of the plurality of connecting pipes away from the connecting plates are commonly fixedly connected to a drain pipe. The connecting plates and the connecting pipes are in through connection. The nutrient solution will flow into the inside of the drain pipe through the connecting pipes. The drain pipe can store the excess nutrient solution.
[0016] The present invention has the following beneficial effects:
[0017] In the present invention, by arranging a spiral penetration ventilation seedling-raising assembly, the spiral infusion pipe and the annular partition form a uniform penetration network, enabling the nutrient solution to slowly infiltrate the soil along a spiral path, and cooperating with the ventilation holes to achieve a gas-liquid double cycle. The ventilation holes provided on the annular partition form a vertical air convection channel, which constitutes a gas-liquid composite cycle with the liquid penetration path of the spiral infusion pipe, thereby being able to promote the three-dimensional development of the root system. The servo motor drives the push plate to move vertically, not only realizing the deep penetration of the nutrient solution, but also being able to regularly discharge the metabolic waste liquid to avoid salt accumulation.
