Facility horticulture refers to the use of artificial facilities and artificial control of environmental factors to completely or partially get rid of the constraints of natural climate and soil conditions in traditional agricultural production, so that plants can obtain the most suitable growth conditions, thereby prolonging the production season and obtaining the best output. mode of agricultural production. The horticultural cultivation frame is the most basic cultivation facility for protected horticulture. It can be used to realize three-dimensional cultivation, greatly reduce the occupied area, improve the land utilization rate, and alleviate the problem of land resource shortage to a certain extent. In addition, people can also cultivate ornamental plants and vegetables and fruits in cities with many high-rise buildings by using this kind of cultivation facilities. They can not only obtain fresh vegetables and fruits, but also beautify their living environment, and truly realize the restoration of lost land. Most of these balcony agricultural and gardening cultivation racks use artificial watering or other inefficient irrigation modes. The management is time-consuming and laborious, and it is impossible to complete a good irrigation and drainage process. This will undoubtedly have a negative impact on the growth of plants, thereby affecting the overall quality. Balcony agricultural cultivation effect.

At present, there is a pipe rack cultivation device on the market. The pipe rack is composed of several layers of planting tanks with different heights. The irrigation system is connected by seepage irrigation pipes laid at the bottom of each planting tank. There is a sump at the water outlet and a small water pump inside. Water can be sent to the uppermost water inlet to form a cycle and irrigate through the water cycle for a certain period of time. This device is easy to operate and has good irrigation effect, but due to the relatively poor water conductivity of the substrate, it takes a long time for irrigation to soak the substrate. In addition, the drainage of this device is mainly discharged naturally through the height difference of the pipe rack. Since there is a certain height difference between the connection between the irrigation pipe and the planting tank and the bottom of the planting tank, there is a problem that some excess water is difficult to discharge.
