Background technique

my country's soilless cultivation has a long history. In recent years, my country's soilless cultivation has entered a stage of rapid development. The area of soilless cultivation and the level of cultivation technology have been unprecedentedly improved. Since soilless cultivation does not use soil but uses nutrient solution or solid substrate plus nutrient solution to cultivate plants, this cultivation method can avoid cumbersome root and soil separation operations, and is convenient for observing the roots of plants. The spray method is a method developed on the basis of hydroponics. This method supplies sufficient oxygen to the roots of the plants, so that the roots can grow a large number of root hairs. Therefore, spray cultivation technology is often used to cultivate plants, and then to observe the growth characteristics of the plant roots, which is of great significance for the image detection and analysis of plant roots. the

Since temperature and humidity have a very important impact on plant growth, adjusting temperature and humidity to provide a suitable growth environment for plant growth is particularly important for promoting plant growth. At present, there are few and imperfect spray cultivation devices that can widely adjust temperature and humidity according to different plant growth characteristics. Existing spray cultivation devices usually adjust the temperature and humidity artificially based on experience. The adjusted temperature and humidity are prone to large deviations and consume a lot of manpower. The quantity needs to be adjusted appropriately, which not only increases the workload, but also requires more nozzles, which increases the cost. In order to solve these existing problems, the present invention provides a spray cultivation device that uses an ultrasonic atomizer to atomize and can automatically regulate temperature and humidity. Different planting tanks have spraying problems under them. the
