Description

Technical Field

[0002] Channel gates are an important part of channel water conservancy construction. They are used to close and open drainage channels, and are used as working gates to adjust flow, control water levels, adjust flow, or as maintenance gates to close orifices to block water. Irrigation refers to the use of water to irrigate the land, mainly including flooding, sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, infiltration irrigation, deficit irrigation, etc., which are divided into irrigation before sowing, irrigation for seedling promotion, irrigation during the growth period, and irrigation in winter. The principle of irrigation is that the amount of irrigation, the number of irrigations, and the time should be determined according to the water requirements of medicinal plants, the growth stage, the climate, and the soil conditions. Irrigation should be timely, appropriate, and reasonable.

[0003] In existing farmland, when releasing water, the gates are usually opened completely directly. After the gates are opened completely, the water flow rate is too high, and the water flow will rush out of the channel or destroy some crops beside the channel, causing losses.
