Description

A countercurrent slow water absorption plant hydroponic automatic planting device

technical field

The utility model relates to the field of agricultural technology, in particular to a hydroponic automatic planting device for countercurrent slow-absorbing plants.

Background technique

Soilless cultivation is a kind of agricultural planting method, specifically refers to the cultivation method that uses water, peat or forest mulch, vermiculite and other media as the substrate of the plant root system to fix the plants, and the plant root system can directly contact the nutrient solution. The created crop root growth environment replaces the soil environment. It can not only meet the needs of crops for nutrients, water, air and other conditions, but also control and adjust these conditions to promote better growth of crops and obtain better vegetative growth. Balanced with reproductive growth, soilless cultivation is divided into substrateless cultivation and substrate cultivation according to different cultivation media. The characteristic of substrateless cultivation is that the cultivated crops do not have a substrate to fix the root system, and the root system is directly in contact with the nutrient solution. Substrateless cultivation is divided into Both aeroponics and hydroponics.

In substrate-free cultivation, aeroponics, also known as aeroponics or aeroponics, uses the filtered nutrient solution to pass through an atomizing spray device under pressure to atomize the nutrient solution into fine droplets and spray it directly onto the plant root system. A soilless cultivation technique to provide the water and nutrients needed for plant growth, while hydroponics refers to a cultivation method that does not use a substrate to fix the root system, so that the plant root system directly contacts the nutrient solution, mainly including deep liquid flow hydroponics, nutrient solution Membrane cultivation and floating plate capillary cultivation, among the three modes, nutrient liquid membrane technology NFT is widely used.

Among the above three modes, deep liquid flow hydroponics requires an additional circulation system. The nutrient solution is pumped from the reservoir to the planting tank, flows from the higher end of the planting tank to the lower end, and forms a flow cycle with the reservoir. The system needs to be driven by electricity. The late-night flow method is similar to the NFT cultivation technology and also requires a circulation system. Because the liquid layer is deep, it is prone to insufficient oxygen supply to the root system. It is necessary to use an air pump to supplement oxygen into the nutrient solution to increase additional power output. . Floating plate capillary technology also requires a circulation system. These three technologies are only suitable for small leafy vegetables such as lettuce, rape, and spinach, and herbal fruits such as strawberries. They are not suitable for grains such as wheat, rice, blueberries, American ginseng, and Yuanhu. , large fruit trees, perennial Chinese herbal medicines and other crops.
