The plant grow rack is a high-efficiency agricultural system that realizes the annual continuous production of crops through high-precision environmental control in the facility. In a limited space, scientists use computers to precisely control the temperature, humidity, light, carbon dioxide concentration, nutrient solution and other environmental conditions required for plant growth and development to obtain high-quality, high-yield agricultural products. So what are the advantages of growing racks over traditional farming systems?
That is to say, intensive production reflects the overall comprehensive benefits of resources, technology and labor, improves the material output per unit area, and alleviates the contradiction between food supply and demand. The plant growth rack adopts a three-dimensional planting method, compresses the area of the equipment to expand the planting area, and effectively utilizes the indoor space and equipment space through reasonable hole design.
That is to fully tap the potential of agricultural and industrial by-products, light, water and other resources, ease the contradiction between man and land, ease the conflict between grain and cash crops, vegetables, fruits, etc. for land, improve the utilization rate of resources, and improve the utilization rate of artificial auxiliary functions. usage efficiency. Take lettuce as an example, it takes about 40 days to mature under natural conditions, but only about 20 days in a plant factory. At the same time, because of multi-layer cultivation, on the same area of land, the output of plant factories can reach dozens or even hundreds of times that of conventional cultivation.
That is to reduce the residue of harmful substances, improve the quality of the agricultural environment and ecological environment, and ease the pressure on the living environment. By controlling the ecological environment in the plant growth rack, an efficient agricultural system that realizes the continuous production of crops every year. Simply put, it is indoor shelf-type vegetable cultivation, which realizes multi-layer soilless cultivation of plants - which cuts off the contact of plants with heavy metals in the outdoor air and soil.
That is, product and environmental safety, which is reflected in the use of multi-species combinations to avoid planting pollution and develop agriculture, and to establish a concept of economic and environmental integration. The plant growth rack adopts hydroponics or aeroponics, and the nutrient solution prepared instead of soil is used to support the growth of crops, so the harm of soil pollution to crops is completely eliminated, and the water used in these nutrient solutions has been purified by professional equipment. , heavy metals, etc. cannot appear in the products of plant growth racks, and it also prevents the impact of water pollution on crops.
The three-dimensional cultivation of plant growth racks is the development trend of soilless cultivation of plants. There are many forms of three-dimensional cultivation racks, and there are many choices of cultivation techniques. In actual production practice, different three-dimensional cultivation should be selected according to different plant varieties. According to various factors such as output, cost, quality, operability, etc., scientific selection is made to maximize benefits.
