In the 1990s, with the rapid development of the greenhouse industry in China, smart greenhouses such as various solar panel greenhouses, glass greenhouses, and solar photovoltaic greenhouses have been continuously constructed. Greenhouse production has also developed from a single vegetable cultivation to flower cultivation and fruit tree cultivation. , Seedlings and other production methods, which put forward higher requirements for greenhouse irrigation equipment. In this way, the greenhouse sprinkler irrigation has developed rapidly. At present, walking sprinklers (shown below) are mainly used in greenhouses, especially potted and bagged crops, plug trays, etc., which require high uniformity of irrigation and spraying in smart greenhouses.

In greenhouse irrigation, when the sprayed water droplets of the fixed micro-sprinkler system fall on the ground surface, the distribution is not uniform, and the drip water needs to be further diffused in the soil to achieve uniform distribution of the sprayed water to the crops. However, in the production of potted and bagged crops, plug tray seedlings, etc., due to the limitation of pots, bags, plug trays and other cultivation containers, the spray water dripping on the ground in the fixed micro sprinkler irrigation system cannot be further diffused, resulting in uneven distribution of irrigation water . Therefore, in these greenhouse production using container cultivation, ordinary fixed micro-sprinkler irrigation systems cannot be used for irrigation. The intelligent greenhouse greenhouse walk-in sprinkler can achieve the ideal distribution uniformity of the sprayed water dripping on the ground through the dense arrangement of micro sprinklers. It can obtain good irrigation results by direct spraying, so it is especially suitable for container cultivation and high spraying is required. Uniformity of greenhouse production and use. Low-range micro sprinklers such as gap type micro sprinklers, centrifugal type micro sprinklers, and eddy current type micro sprinklers are generally used in intelligent greenhouse greenhouse walk-on sprinklers. The uniformity of the spraying water distribution on the ground of the greenhouse greenhouse sprinkler with excellent performance should be more than 90% (the uniformity of the spraying water on the ground by the ordinary fixed micro-sprinkling system is only about 70%). In addition, since the walking sprinkler can obtain a high spray uniformity, in the greenhouse production, it can also be equipped with fertilizer injection or dosing devices, and the walking sprinkler can be used to uniformly fertilize or spray the greenhouse greenhouse crops. Not only can greatly reduce labor intensity, but also can improve the utilization rate of fertilizers and medicines, and reduce environmental pollution in greenhouses. Therefore, walking sprinklers are increasingly used in modern greenhouse production.
