Traditional surface irrigation includes border irrigation, furrow irrigation, flood irrigation and flood irrigation, but these irrigation methods often consume a lot of water and have low water utilization efficiency, which is a very unreasonable agricultural irrigation method. In addition, ordinary sprinkler irrigation technology is a relatively common irrigation method in China's agricultural production. However, the water utilization efficiency of ordinary sprinkler irrigation technology is not high. Modern agricultural micro-irrigation techniques include micro-sprinkler irrigation, drip irrigation, infiltration irrigation, etc. These irrigation technologies generally have good water-saving performance, and the water utilization rate is higher than that of traditional irrigation modes.
目前在农业灌溉的过程中,一些灌溉的过程需要定时灌溉,在进行定时灌溉的过程中,水箱内的水分在进行进水时,由于采用的灌溉的方式为定时灌溉,因此水箱内的水分在进行加水时,水箱内需要加入的水量不确定,因此容易让水箱内的水分出现溢出的情况。At present, in the process of agricultural irrigation, some irrigation processes require regular irrigation. In the process of regular irrigation, when the water in the water tank is entering water, the water in the water tank is When adding water, the amount of water that needs to be added in the water tank is uncertain, so it is easy to cause the water in the water tank to overflow.
