Description

Technical Field

[0001] The utility model relates to the technical field of irrigation equipment, in particular to greenhouse circulation irrigation equipment. Background Art

[0002] With the development of the planting industry, greenhouse planting has become more and more common. In recent years, greenhouses have grown stronger and stronger. How to apply water and fertilizer more efficiently and intelligently has become an important research topic. Greenhouses mainly cultivate plants through cultivation beds, and use the sprinklers in the irrigation system to irrigate the crops with water in the water pipes. Greenhouses are mainly used in seasons that are not suitable for plant growth. They can provide greenhouse growth periods and increase yields. They are mostly used for cultivation or seedling cultivation of warmth-loving vegetables, flowers, trees and other plants in low temperature seasons. In order to ensure the normal growth of crops and obtain the economic benefits of high and stable yields, crops must be supplied with sufficient water and fertilizer. The amount of irrigation, number of irrigations and time should be determined according to the water requirements of the plants, the growth stage, the air temperature and humidity, and the soil conditions. Irrigation should be timely, appropriate and reasonable. Among them, sprinkler irrigation uses a water pump and a pipe system to irrigate water through pressure spraying. It can be used for large-scale plant irrigation. Although the sprinkler irrigation method can quickly irrigate crops, due to the large-scale spraying, the plant's absorption rate of water is not high, and the excess water will accumulate at the bottom of the cultivation bed, which can easily cause root rot of the crops. In addition, the water cannot be reused after being discharged, resulting in a waste of water resources. For this reason, we proposed a greenhouse circulating irrigation equipment.
