Description

Root control cultivation device Technical field

The invention relates to the field of cultivation beds, in particular to a device capable of adjusting the distance between seedling roots and nutrient liquid level.

Background technique

Soilless culture is a way of cultivating plants with nutrient solution or substrate instead of natural soil, which generally includes hydroponics and substrate culture. Hydroponics, also known as nutrient solution culture, is a cultivation method in which the roots of plants are directly immersed in a nutrient solution. This nutrient solution can replace the soil and provide growth factors such as water, nutrients, and oxygen to the plants, so that the plants can grow normally. Hydroponics has been widely used in the three-dimensional cultivation of facilities in greenhouses and plant factories. Hydroponics planting requires seedlings first, which can improve the germination rate of seeds and the quality of seedlings. In plant factories, it can also save energy consumption for lighting under lights and other costs. .

Hydroponics in plant factories currently uses sowing, accelerating germination, and then refining seedlings to obtain small seedlings. Most of these stages are cultivated with dense sponge blocks, but as the seedlings become larger and larger, the previous density cannot meet the growth space of the seedlings. Therefore, the subsequent seedling raising stage needs to be transplanted to a cultivation board with a lower density. After the seedlings are raised, they are planted on the corresponding planting board to grow. The whole process is cumbersome. The cultivation board needs to be replaced twice, which causes manpower and material resources. Waste, especially when the seedlings' roots are entangled seriously at the end of the seedling reforming. This is a major limitation of hydroponic vegetables at present. The robustness of the root system greatly determines the growth of the plants in the later stage. When the seedlings are transplanted to the seedling tray at the end of the seedling reforming , It often causes the root system to be cut off and damage the roots, and it takes a certain time to re-root and recover, which leads to the reduction of the growth regularity of the seedlings in the later stage, and the different sizes of vegetables when harvesting, which seriously affects the yield.

Another kind of substrate culture is cultivation in which solid materials such as grass charcoal replace soil. Seedling containers such as plugs, nutrient bowls, and seedling pots are used to grow seedlings. Most of the existing plant seedling containers have a through hole at the bottom. Water and fertility causes the root system to grow from the bottom hole to the outside of the container. The root system is easily broken during transplanting, which leads to damage to the seedling root system. It takes a long time to re-root, which directly leads to slow growth and affects later Growth and development.

In summary, due to the cumbersome operation of the existing hydroponics technology during the entire seedling raising period, it is easy to cause root damage during transplanting, resulting in uneven growth of the seedlings in the later stage, which seriously affects the yield. Therefore, how to design a soilless culture root control and seedling raising device that prevents the roots from being exposed and damaged and reduces the number of transplants is a technical problem to be solved urgently by those skilled in the art.

Summary of the invention

In order to solve the above technical problems, it is necessary to provide a root-controlling cultivation device that can simplify the operation process during the seedling raising period, reduce labor and other costs, reduce the exposure of roots during transplanting, and improve plant uniformity.

In order to achieve the above objective, the present invention provides a root-controlling cultivation device, which specifically includes the following structure: the root-controlling cultivation device of the present invention includes a seedling tray and a permeable net pocket, and the seedling tray is provided with a plurality of seedling holes, The cross-section of the seedling hole is round or rectangular, and can also be any other shape.

The breathable and permeable net bag is equipped with multiple nursery hole nets that match the nursery holes, so that the roots of the plants can be tightly clumped during the growth process, and the phenomenon of intertwining will not occur, which solves the problem of too long roots. The problem of moving into the cultivation hole reduces plant root damage during transplanting.

Further preferably, the air-permeable net bag is sleeved on the outer wall of the bottom of the seedling tray from bottom to top, so that the plant roots can grow together tightly in a cluster, which effectively prevents the plant roots from being exposed and entangled when transplanting and pulling out. The root system is damaged, and the problem that the plant root system is too long is not easy to move into the cultivation hole.

Further preferably, the air-permeable and water-permeable net bag is embedded in the seedling tray from top to bottom, and the seedling hole net is embedded in the seedling hole, which prevents the roots from being exposed and entangled with each other when the plant grows, and solves the problem that the roots of the plants are too long. The problem of moving into the cultivation hole is conducive to removing the plants in the seedling hole as a whole when transplanting, and the work steps are simplified.

The breathable and permeable net bag in the device of the present invention is nested from top to bottom on the inner wall of the seedling hole on the seedling tray or embedded in the seedling hole. While preventing the root system from being exposed and entangled, it also facilitates the transplantation of later plants. When planting, the air permeable and permeable net bag can be removed as a whole, reducing the process of transplanting one by one, simplifying the work steps, and reducing the waste of human resources.

4. The breathable and permeable net bag of the device of the present invention also solves the problem that the plant roots are too long to be moved into the cultivation hole.
