Description

At the same time, it can guide farmers to apply fertilizers accurately, deal with soil boron deficiency problems, reduce costs and reduce environmental pollution. In addition, its research results can provide data support for plant nutrition theory, improve the theoretical system, and provide reference for other plant nutrition research.

[0003] In the experiment of studying the effect of boron deficiency on soybean seedlings, the nutrient solution inside the soybean breeding experimental box needs to be replaced regularly. In the early stage, the soybeans in the two control groups use the same nutrient solution.

DETAILED DESCRIPTION

[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0020] According to one embodiment of the present invention, Figures 1 to 10 Shown.

[0021] In an experiment to study the effect of boron deficiency on soybean seedlings, the soybean seeds were first soaked in a 10% sodium hypochlorite solution for ten minutes for disinfection, rinsed and then soaked in water for four hours, and then cultured in two layers of wet filter paper in a culture dish. After the seeds germinated for four days, the bean sprouts were transplanted into the breeding experimental box of the present invention for a breeding experiment. Two boxes of soybean seedling control groups were set up in the experiment. In the early stage of breeding, the two boxes of soybean seedlings used the same nutrient solution, and the nutrient solution was replaced every two days. After eight days of cultivation, the nutrient solution was replaced. One group was cultivated using a full nutrient solution, and the other group was cultivated using a boron-deficient nutrient solution.

[0022] When replacing the nutrient solution, due to the different compositions of the new and old nutrient solutions, if the old nutrient solution still remains on the soybean root system, it will be difficult to control only the variable of whether it contains boron in subsequent control experiments, which can easily lead to inaccurate experimental results. In order to prevent the influence of residual nutrient solution, it is usually necessary to clean the cultivation box and the soybean root system. The thickness and strength of soybean roots are not the same. Generally, the main root system in the middle is thicker and stronger, and the roots on the side are thinner and weaker. Different roots can withstand different amounts of water impact. If the impact force is small, the roots intertwined in the middle position are not clean enough. If the impact force is large, the thinner and weaker roots on the side are easily damaged. In order to solve this problem, the present invention has made the following design on the breeding experimental box: A soybean breeding experiment box, including a breeding experiment box main body 1, a circulating liquid component 2 is installed inside the breeding experiment box main body 1, the circulating liquid component 2 is used to introduce or discharge nutrient solution and clean water into the interior of the breeding experiment box main body 1, the circulating liquid component 2 includes a liquid separation interlayer 201, an upper support plate 202, and a lower support plate 203, the liquid separation interlayer 201 is composed of the upper support plate 202 and the lower support plate 203, and the interior of the liquid separation interlayer 201 is evenly embedded with a soybean breeding component 3, the soybean breeding component 3 includes a pressure dividing interlayer 301, an inner planting trough 302, and an outer planting trough 303, the inner planting trough 302 and the outer planting trough 303 are fixedly connected, and the inner planting trough 302 and the outer planting trough 303 are surrounded to form a pressure dividing interlayer 301, the shape of the pressure dividing interlayer 301 is set to be hemispherical, the outer planting trough 303 is fixedly connected to the upper support plate 202, and the outer planting trough 303 is fixedly connected to the lower support plate 203.

[0023] Four days after germination, the soybean seedlings are fixed on the top of the soybean breeding component 3 through the soybean support component 5, and the bottom of the soybean seedlings is inserted into the inner planting groove 302. During the growth process, its roots will pass through the root diversion component 4 through the pressure dividing interlayer 301 and grow downward. When replacing the nutrient solution, after all the old nutrient solution inside the breeding experiment box body 1 is discharged outward through the liquid outlet 208, clean water can be introduced into the liquid dividing interlayer 201 through the liquid inlet pipe 204 for breeding. The inside of the experimental box body 1 and the root system of the soybean seedlings are rinsed. A circle of liquid inlet holes 305 are opened in a circular array on the top of the pressure-dividing interlayer 301. One side of the liquid inlet hole 305 is connected to the pressure-dividing interlayer 301, and the other side of the liquid inlet hole 305 is connected to the liquid-dividing interlayer 201. The liquid-dividing interlayer 201 is gradually tilted downward from left to right. Clean water is introduced from the higher side of the liquid-dividing interlayer 201. Under the action of gravity, the liquid gradually flows to the right along the inclined liquid-dividing interlayer 201. At the same time, the liquid enters and fills the interior of the pressure-dividing interlayer 301 through the liquid inlet hole 305. Since the pressure-dividing interlayer 301 is hemispherical, when the pressure-dividing interlayer 301 is filled with water, the middle position of the pressure-dividing interlayer 301 has a deeper water level and a higher water pressure, while the side position has a shallower water level and a lower water pressure. Therefore, the thicker roots in the middle of the soybean root system correspond to a higher water pressure, and the thinner and weaker roots on the side of the soybean root system correspond to a slightly smaller water pressure. The higher water pressure can generate a stronger water flow impact force, which has a better flushing effect on the nutrient solution remaining on the thicker roots in the middle of the soybean root system and can more thoroughly flush away the nutrient solution attached to the surface of the thick roots and the gaps between the root hairs. The water pressure corresponding to the thin and weak roots on the side is slightly smaller, which can prevent mechanical damage to the thin and weak roots caused by excessive water pressure. The thin and weak roots are relatively fragile, and excessive water flow impact force may destroy their cell structure or break the roots. This relatively mild water pressure can protect the integrity and normal physiological function of the thin and weak roots while flushing the nutrient solution.

[0024] When replacing the nutrient solution in a traditional seedling box to clean the soybean roots, the roots are usually only flushed and cleaned with the entire water flow from the water outlet. Due to the limitations of the water flow direction and angle, some soybean seedling roots may not be fully covered by the water flow, resulting in blind spots in the flushing. However, in the present invention, each soybean root has a corresponding soybean breeding component 3. The top-down flushing ensures that the water flow directly acts on the root system of each soybean plant, so that all parts of the root system can be evenly flushed, effectively avoiding the problem of nutrient solution residue caused by uneven flushing. The top-down flushing allows the water flow to flow along the growth direction of each soybean root system, reducing the impact of mutual obstruction between roots on the flushing effect, and ensuring that each soybean root system can be fully flushed. In addition, the top-down flushing method of the present invention has the water flow direction consistent with the growth direction of the seedlings, which has a small lateral force on the seedlings, effectively reducing the risk of seedlings falling over, and facilitating the protection of the normal growth of the seedlings.

[0025] Traditionally, the roots of soybean seedlings usually take root downward through the holes in the planting board. Even if the soybean roots are cleaned by flushing from top to bottom, during the flushing process, due to uneven force, the soybean roots will stick to one side of the hole, so that the water flow can only pass through the other side, which easily leads to excessive flushing on one side of the soybean root system and insufficient flushing on the other side. To solve this problem, the present invention is provided with the following structure: The outer wall of the outer planting trough 303 is evenly provided with drainage holes 304, and the drainage holes 304 are connected to the pressure dividing interlayer 301. The root diversion assembly 4 is evenly embedded in the pressure dividing interlayer 301, and the root diversion assembly 4 corresponds to the drainage holes 304 one by one. The root diversion assembly 4 includes a silicone membrane petal 401, and the silicone membrane petal 401 is arranged in a circular array. There are four, and the four silicone membrane petals 401 form a funnel-shaped root channel with a large upper opening and a small lower opening. The funnel-shaped root channel passes through the drainage hole 304. , and the bottom end of the funnel-shaped root channel extends out of the outer planting groove 303, the top of the silicone membrane petal 401 is fixedly connected to the inner planting groove 302, and the bottom end of the silicone membrane petal 401 is fixedly connected to the protective strip 404, the outer wall of the silicone membrane petal 401 is fixedly connected to the guide strip 402, and the guide strip 402 passes through the interior of the drainage through hole 304, and the bottom end of the guide strip 402 is provided with a guide end 403, the shape of the guide end 403 is set to a pointed shape, and the side of the guide end 403 close to the protective strip 404 is vertically downward.

[0026] Since the nutrient solution is below the inner planting trough 302, under the action of the plant's hydrotropism and geotropism, the roots of the soybean seedlings will take root downward through the funnel-shaped root channel formed by the silicone membrane petals 401. When flushing, the water flow inside the pressure-dividing interlayer 301 passes through the drainage hole 304 downward and flows downward along the guide strip 402. Under the action of the silicone membrane petals 401 and the protective strip 404, the roots of the soybeans can be supported in the middle position of the drainage hole 304, and the four evenly distributed guide strips 402 The water flowing out of the drainage hole 304 can be directed to four different sides of the soybean root system. At the same time, the water infiltrating into the silicone membrane petal 401 will flow downward through the gaps between the silicone membrane petals 401. These four gaps and the four guide strips 402 are staggered and evenly distributed around the soybean root system, so that the water flow can effectively wrap around the various sides of the soybean root system and flow downward, avoiding dead corners in flushing, and ensuring that every part of the root system can be flushed by the water, thereby comprehensively improving the cleaning effect.

[0027] Even within root diversion assemblies 4 located at the same height, due to the varying thickness of the roots within them, thicker roots push the silicone membrane petals 401 further outward, resulting in a smaller gap between the outer side of the silicone membrane petals 401 and the drainage holes 304. Under the same water pressure, because the flow rate is inversely proportional to the flow area, the flow rate and impact force of the water flowing through it are slightly greater. Conversely, the flow rate and impact force of the water flowing through thinner roots are slightly smaller. The design of the root diversion assembly 4 aligns the impact force of the water flow with the thickness of the soybean roots. Thick roots typically have a larger surface area, and relatively more impurities such as nutrient solution adhere to them, requiring a greater impact force to effectively clean them. Thicker roots push the silicone membrane 401 outward, reducing the gap between the outer side of the membrane 401 and the drainage hole 304. This increases the water flow rate and impact force, allowing for more effective flushing of the coarse roots, removing stubborn impurities and achieving a better cleaning effect. Fine roots, on the other hand, require relatively fewer impurities to be cleaned, and the smaller impact force meets the cleaning needs without damaging them. This allows for precise adjustment of flushing force based on root size, optimizing the overall flushing effect.

[0028] A liquid outlet pipe 205 is fixedly connected to the bottom plate of the breeding experiment box body 1, and liquid outlet holes 206 are evenly opened on the outer wall of the breeding experiment box body 1. A liquid pump 207 is installed on the outer wall of the breeding experiment box body 1. The input end of the liquid pump 207 is connected to the liquid outlet pipe 205, and the output end of the liquid pump 207 is fixedly connected to the liquid inlet pipeline 204, and the liquid inlet pipeline 204 is connected to the liquid separation interlayer 201. During the cultivation process, the liquid pump 207 can be started, and the nutrient solution inside the breeding experiment box body 1 enters the liquid outlet pipe 205 through the liquid outlet hole 206, and under the action of the liquid pump 207, it is transported upward through the liquid inlet pipeline 204 into the interior of the liquid separation interlayer 201, and flows downward along the soybean root system through the soybean breeding component 3 and the root system diversion component 4 to form a cycle. Nutrient circulation prevents uneven nutrient concentration and stratification within the hydroponic chamber. As the nutrient solution flows downward along the roots, it mixes thoroughly, ensuring that the soybean roots receive a balanced supply of nutrients at different locations, avoiding the negative impact of localized nutrient concentration or dilution on soybean growth. This flow pattern also simulates the movement of water and nutrients in natural soil under the influence of gravity, allowing the soybean roots to experience a similar nutrient flow in a natural environment, allowing them to grow and extend downward more naturally. Root growth follows the direction of nutrient flow, helping to better distribute the roots within the hydroponic chamber and expand their absorption area. The flow of nutrient solution also provides a certain physical stimulation to the roots, which promotes root cell metabolism, enhances root respiration and absorption, and improves root vitality and growth rate.

[0029] The bottom of the breeding experiment box body 1 is fixedly connected with a liquid outlet 208, and the liquid outlet 208 is connected to the inner cavity of the breeding experiment box body 1. The liquid outlet 208 is used to discharge the old nutrient solution and the waste water used for flushing out of the breeding experiment box body 1.

[0030] The upper support plate 202 and the lower support plate 203 are arranged in parallel, and there is a gap fit between the upper support plate 202, the lower support plate 203 and the inner wall of the breeding experiment box body 1. Two groups of lifting handles 6 are symmetrically arranged on the top of the upper support plate 202, and the lifting handles 6 are fixedly connected to the upper support plate 202. The inner wall of the breeding experiment box body 1 is fixedly connected with a support frame 7, and there is a gap fit between the support frame 7 and the liquid separation interlayer 201. The entire soybean cultivation plate can be taken out upward from the inside of the breeding experiment box body 1. After the experiment is over, it is convenient to clean and pull out the soybean seedlings inside it, so that this breeding experiment box can be reused, saving costs.

[0031] The top of the pressure-dividing interlayer 301 is fixedly connected with a soybean supporting assembly 5 , which is used to support the transplanted bean sprouts from the stems to prevent them from tilting. The soybean support assembly 5 includes a support bar 505, the bottom end of the support bar 505 is fixedly connected to the pressure-dividing interlayer 301, and the top of the support bar 505 is fixedly connected to a C-shaped frame 501, the inner wall of the C-shaped frame 501 is fixedly connected to a fixing clamp 502, and the fixing clamp 502 and the pressure-dividing interlayer 301 are coaxially arranged, the stem of the soybean seedling is clamped inside the fixing clamp 502, and two groups of springs 503 are symmetrically arranged on the sides of the fixing clamp 502, one end of the spring 503 is fixedly connected to the fixing clamp 502, and the other end of the spring 503 is fixedly connected to the C-shaped frame 501, the open end of the fixing clamp 502 is fixedly connected to a snap-in opening 504, the snap-in opening 504 is an eight-shaped opening design, and the connection between the snap-in opening 504 and the fixing clamp 502 is rounded to reduce scratches on the soybean seedlings caused by the bending.
