The invention discloses a multifunctional soilless culture device.The multifunctional soilless culture device comprises a culture box.The culture box is composed of a water tank on the lower portion and a glass cover on the upper portion.A temperature detection unit, an automatic air pressure balancing valve and a CO2 valve are arranged on the glass cover.The bottom of the water tank is connected with a circulating aeration unit, the circulating aeration unit comprises a closed container and a water tower connected with the closed container, the top end of the closed container is communicated with the bottom of the water tank through gas distributing ports, the water level of the water tower is higher than the top end of the closed container, a water meter and a water control valve are arranged between the water tower and the closed container, and an aeration valve is arranged on the upper portion of the closed container.A water pump is connected to the bottom of the closed container.The automatic air pressure balancing valve is used for adjusting the air pressure in the glass cover.The multifunctional soilless culture device has the advantages of being convenient to operate, complete in function and the like.By means of the multifunctional soilless culture device, the purposes of oxygenation, light supplement and CO2 supply in the soilless culture technology are achieved, the demands of plants for water, fertilizer, air and heat are more reasonable, and thus the increment of plants is increased.
Description
technical field [0001] The invention belongs to the technical field of facility agriculture cultivation, and in particular relates to a multifunctional soilless cultivation device. Background technique [0002] At present, soilless cultivation technology has been widely used in my country's facility agriculture, such as floating blind seedlings of flue-cured tobacco, nutrient solution cultivation of vegetables and flowers, etc. Compared with foreign countries, my country's soilless cultivation technology has a lower level of equipment, especially ventilation, light supplement, temperature control, CO 2 Fertilization and other aspects are not perfect, which affects the growth and yield of cultivated plants. Aiming at the above-mentioned problems existing in my country's soilless cultivation devices, a new multifunctional soilless cultivation device is provided. Contents of the invention [0003] Purpose of the invention: to solve the problem of increasing oxygen, suppleme...
