Description

Technical Field

[0001] This utility model belongs to the field of forestry ecological seedling technology, specifically relating to a seedling raising device for forestry ecology. Background Technology

[0002] Forestry is a key area in ecological civilization construction, and its healthy and sustainable development depends on the supply of high-quality seedlings. Forestry ecological seedling cultivation aims to cultivate seedlings with good environmental adaptability and stability for use in projects such as afforestation in mountainous areas and ecological restoration of challenging sites. In this process, the quality of the seedlings directly affects the survival rate of afforestation, the initial growth status, and even the restoration effectiveness of the entire forest ecosystem.

[0003] Currently, conventional forestry seedling cultivation devices and methods are mostly carried out in standardized nursery environments with controlled conditions and sufficient water and fertilizer. While this model can ensure rapid morphological growth of seedlings in the short term (such as growth in seedling height and ground diameter), it also easily leads to seedlings being in a "favorable" environment for a long time, resulting in a significant "greenhouse effect." This manifests as weak stems, underdeveloped root systems, an imbalanced root-to-shoot ratio, tender tissue structure, and insufficient induction of stress-resistance physiological mechanisms. When such seedlings are transplanted from well-conditioned nurseries to actual site environments such as mountainous areas with variable climates, poor soil, and frequent water stress, they often suffer from low survival rates, long recovery periods, stunted growth, and even mass mortality due to their inability to adapt to the drastic environmental changes—a problem known as "poor adaptability after being moved to the mountains." This not only causes economic losses but also seriously affects the progress and quality of ecological construction. Therefore, we propose a forestry ecological seedling cultivation device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to propose a forestry ecological seedling raising device that can control the degree of drought in the seedling substrate to fully induce the stress resistance physiological mechanism of seedlings.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A seedling raising device for forestry ecology includes a seedling tube with several drainage holes at the bottom, a seedling substrate inside the seedling tube, a support tube fixedly installed at the lower end of the seedling tube, a weighing platform below the support tube, and a drainage mechanism inside the support tube to guide the downward flow of air and water inside the seedling tube.

[0007] Further specifying, the drainage mechanism includes a fixed cover, a conveying cylinder fixedly installed at the bottom center of the fixed cover, multiple fixed pipes fixedly inserted into the conveying cylinder, an air guide cover fixedly installed at the end of the fixed pipes, and a fan disposed inside the air guide cover. The bottom center of the fixed cover is concave downwards, the top of the fixed cover is in close contact with the bottom of the seedling cylinder, the end of the fixed pipe penetrates the wall of the supporting cylinder, and the fixed pipe is connected to the fixed cover through the conveying cylinder. With this structural design, when the fan is working, the flow velocity at the end of the fixed pipe and at the fixed cover increases, and the pressure decreases, which can drain the moisture from the substrate in the seedling cylinder, thereby controlling the moisture content of the substrate.

[0008] Furthermore, the height of the fixed pipe near the conveying cylinder from the ground is greater than the height of the other end of the fixed pipe from the ground. This structural design allows the fixed pipe to smoothly guide the water output from the fixed cover and the conveying cylinder.

[0009] Furthermore, a fixed post with a conical upper end is fixedly installed at the bottom of the inner wall of the conveying cylinder. This structural design allows the conical upper end of the conveying cylinder to be sealed off, preventing water from accumulating inside the conveying cylinder.

[0010] Furthermore, the weighing platform is equipped with a high-precision weighing sensor and controller, and the upper end of the weighing platform has a positioning boss that matches the lower end of the support cylinder. This structural design facilitates the assembly of the support cylinder and the weighing platform through the positioning boss.

[0011] Further specifying, a ring-shaped water supply pipe is provided above the seedling tube, and support rods are fixedly installed on the ring-shaped water supply pipe at evenly spaced intervals. Multiple water outlets with water outlet directions facing into the seedling tube are fixedly installed on the inner side of the ring-shaped water supply pipe. An inlet pipe is fixedly installed on the ring-shaped water supply pipe, and a water pump is installed at the end of the inlet pipe. The water pump is electrically connected to the controller. This structural design is simple and easy to use.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] This invention uses a drainage mechanism to guide air and moisture downwards from the seedling tube, and a weighing platform to measure the moisture content of the seedling substrate. The drainage mechanism, in conjunction with the weighing platform, allows the seedling substrate to maintain air circulation while controlling the degree of drought, thus fully inducing the seedling's stress resistance physiological mechanism.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] like Figures 1-6 As shown, this utility model discloses a seedling raising device for forestry ecology, including a seedling tube 1 with several drainage holes at the bottom, a seedling substrate inside the seedling tube 1, a support tube 2 fixedly installed at the lower end of the seedling tube 1, a weighing platform 3 below the support tube 2, and a drainage mechanism inside the support tube 2 to guide the air and water inside the seedling tube 1 to flow downward.

[0033] The drainage mechanism includes a fixed cover 21, a conveying cylinder 22 fixedly installed at the bottom center of the fixed cover 21, multiple fixed pipes 23 fixedly inserted into the conveying cylinder 22, a wind guide cover 24 fixedly installed at the end of the fixed pipe 23, and a fan 25 set inside the wind guide cover 24. The bottom center of the fixed cover 21 is concave downwards, and the top of the fixed cover 21 is in close contact with the bottom of the seedling cylinder 1. The end of the fixed pipe 23 penetrates the cylinder wall of the support cylinder 2. The fixed pipe 23 is connected to the fixed cover 21 through the conveying cylinder 22. The ground clearance of the end of the fixed pipe 23 near the conveying cylinder 22 is greater than the ground clearance of the other end of the fixed pipe 23, so that water can be smoothly guided to the outside of the support cylinder 2. A fixed column 221 with a tapered upper end is fixedly installed at the bottom of the inner wall of the conveying cylinder 22.

[0034] The weighing platform 3 is equipped with a high-precision weighing sensor and controller. The upper end of the weighing platform 3 is provided with a positioning boss 31 that matches the lower end of the support cylinder 2. The positioning boss 31 facilitates the assembly of the weighing platform 3 and the support cylinder 2.

[0035] A ring-shaped water supply pipe 4 is installed above the seedling tube 1. Support rods 41 are fixedly installed on the ring-shaped water supply pipe 4 at uniform intervals. Multiple water outlets 42 with water outlet directions facing into the seedling tube 1 are fixedly installed on the inner side of the ring-shaped water supply pipe 4. A water inlet pipe 43 is fixedly installed on the ring-shaped water supply pipe 4. A water pump is installed at the end of the water inlet pipe 43. The water pump is electrically connected to the controller. The controller can calculate the moisture content of the seedling substrate in the seedling tube 1 through the weight data transmitted by the high-precision weighing sensor, and can control the operation of the water pump or fan through the moisture content information to control the moisture content of the substrate within a set threshold.

[0036] The method of using this utility model is as follows:

[0037] When in use, the weight of the seedling tube 1, the support tube 2 and the drainage mechanism inside the support tube 2 are measured by the weighing platform 3. When the seedling tube 1 is filled with seedling substrate and planted seedlings, the weighing platform 3 works in sequence to measure the weight of the seedling substrate and the weight of the seedlings.

[0038] After measuring the weight of the seedling substrate and the weight of the seedlings, the controller controls the water pump to replenish the seedling substrate through the inlet pipe 43, the ring water pipe 4 and the outlet end 42. The weighing platform 3 monitors the weight of the seedling cylinder 1 and the support cylinder 2 in real time. The controller can calculate the moisture content of the seedling substrate based on the measured weight.

[0039] When the seedlings are growing normally, the fan 25 operates, and the water in the seedling substrate can be output to the outside through the fixed cover 21, the conveying cylinder 22 and the fixed pipe 23, thereby reducing the moisture content of the substrate. When the moisture content of the substrate drops to the set threshold, the controller controls the water pump to operate, and replenishes the substrate with water through the ring water pipe 4 and the water outlet 42 until the target moisture content is reached. Continuous stress, cyclic stress or gradual stress can be used as needed to fully induce the stress resistance physiological mechanism of the seedlings.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
