Description

Technical Field

[0001] This utility model relates to the field of alfalfa cultivation, specifically to a root collection device for alfalfa cultivation. Background Technology

[0002] Alfalfa is the fresh or dried whole herb of alfalfa, a legume. It is cultivated or semi-wild throughout China. It tastes bitter, astringent, and slightly sweet, and enters the spleen, stomach, and kidney meridians. It has the effects of moistening the intestines and relieving constipation, lowering cholesterol, and improving anemia. In order to understand the growth status of alfalfa and select superior seeds, the roots of alfalfa in the incubator are usually taken out after the alfalfa has grown, collected, and the nutritional components in the roots are analyzed.

[0003] In the cultivation of alfalfa, soil cultivation is usually used to ensure that the seeds can better adapt to field planting. After the seeds are sown in a soil cultivation box, an appropriate amount of nutrient solution is sprayed regularly to ensure that the alfalfa obtains sufficient nutrients during its growth. After the alfalfa has finished growing, the soil layer is removed, the root system of the alfalfa is taken out as a whole and sent to the laboratory for nutritional testing.

[0004] When digging out the roots of alfalfa, the divergent growth of the alfalfa root system causes the roots to become entangled in the limited environment, making it difficult to separate the roots during collection. In addition, root damage is inevitable during the separation process, which can lead to inaccuracies in the root test data. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing root collection devices for alfalfa cultivation make it difficult to ensure the integrity of the plant when dividing alfalfa roots because the roots become entangled during the growth process.

[0007] As an improvement, the bottom surface of the soil cultivation box is provided with a nutrient solution recovery tank, and above the nutrient solution recovery tank is a ceramic ball partition layer to ensure the air permeability of the soil cultivation box. The nutrient solution recovery tank is isolated from the ceramic ball partition layer by a permeable plate.

[0008] As an improvement, a drain outlet that is plugged with a rubber stopper is provided on one side of the nutrient solution recovery tank.

[0009] As an improvement, the top two sides of the detachable root system limiting groove plate are provided with lifting handles to facilitate the removal of the detachable root system limiting groove plate.

[0010] As an improvement, the ventilation cloth is made of polypropylene nonwoven fabric.

[0011] As an improvement, the detachable root system limiting groove plate is made of ceramic material.

[0012] The advantages of this invention compared with the prior art are as follows: This device plants each seed separately in the cavity formed by the detachable root limiting groove plate. The ventilation cloth ensures that the roots of alfalfa will not become entangled with the roots of other plants during the growth process. Furthermore, since the cavity side plate of the detachable root limiting groove plate has exchange holes, the aeration performance of the soil and the penetration ability of the nutrient solution can be guaranteed.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] As per the instruction manual Figure 1 , 2As shown in Figure 4, the soil cultivation box includes a soil cultivation box 1. The bottom surface of the soil cultivation box 1 is provided with a nutrient solution recovery tank 11, and above the nutrient solution recovery tank 11 is a ceramic ball partition 12 to ensure the air permeability of the soil cultivation box 1. The nutrient solution recovery tank 11 is separated from the ceramic ball partition 12 by a permeation plate 13. One side of the nutrient solution recovery tank 11 is provided with a drain port 111 blocked by a rubber stopper. The permeation plate 13 is welded above the bottom surface of the soil cultivation box 1, so that the soil cultivation box 1 can prevent excess nutrient solution, thereby avoiding drowning the plants. To facilitate the drainage of nutrient solution, a nutrient solution recovery tank is provided with a permeation plate 12 above the bottom surface of the soil cultivation box 1. A drain outlet 111 is opened on one side of the nutrient solution recovery tank 11 and blocked with a rubber stopper to ensure that there is not too much nutrient solution in the nutrient solution recovery tank 11. In order to ensure that the soil does not block the through holes on the permeation plate 13 while the nutrient solution is permeating into the nutrient solution recovery tank 11, a layer of ceramsite balls 12 is laid between the permeation plate 13 and the soil layer (placing the ceramsite balls at the bottom of the pot can solve the problem of soil leakage at the bottom, and its breathability can also prevent the roots of the plant from rotting, making your plant healthier; at the same time, the lightweight nature of the ceramsite balls also reduces the weight of the entire potted plant).

[0020] As per the instruction manual Figure 2 , 3 As shown in Figure 4, the soil cultivation box 1 has a detachable root system limiting groove plate 2 with several cavities inside. The detachable root system limiting groove plate 2 is made of ceramic, and several exchange holes 21 are provided on the inner cavity sidewalls of the detachable root system limiting groove plate 2 to facilitate the flow of nutrients in the soil. Each cavity of the detachable root system limiting groove plate 2 has a ventilation cloth 3 to restrict the extension direction of seed roots. The ventilation cloth 3 is made of polypropylene non-woven fabric. The top two sides of the detachable root system limiting groove plate 2 have lifting handles 22 to facilitate the removal of the detachable root system limiting groove plate 2. The detachable root system limiting groove plate 2 made of ceramic is installed above the ceramsite ball partition 12, and the cavities of the detachable root system limiting groove plate 2 are... Multiple air exchange holes 21 are drilled in the side wall to ensure air and water permeability between the cavities. Since the detachable root limiting groove plate 2 is made of ceramic, it will not degrade or corrode, ensuring its service life. A polypropylene non-woven ventilation cloth 3 is attached to the inner wall of the cavity of the detachable root limiting groove plate 2 to ensure that the alfalfa roots do not extend beyond the cavity, thus preventing root entanglement during root collection. The lifting handles 22 on both sides of the detachable root limiting groove plate 2 ensure that it does not press against the ceramic pellet spacer 12 while facilitating easy removal and placement. Finally, soil is laid in the cavity of the detachable root limiting groove plate 2, completing the alfalfa planting.

[0021] In the specific implementation of this invention, alfalfa seeds are planted in the soil inside the ventilation cloth 3. Nutrient solution is then added periodically, allowing individual alfalfa seeds to grow within the ventilation cloth 3. During this period, watering is required periodically, or excess nutrient solution is drained through the drain outlet 111. Once the alfalfa seeds have grown, the researchers hold the lifting handle 22 and pull the detachable root limiting groove plate 2 out of the soil cultivation box 1. The ventilation cloth 3 and the soil inside it will then fall out. Finally, the soil block is removed, and a vibrating screen or similar device is used to shake off the soil from the alfalfa roots, thereby obtaining a complete alfalfa root system.
