Catchment period irrigation method

Abstract

The invention provides a catchment period irrigation method, which effectively solves conflicts existing in irrigation and substantially improves irrigation efficiency. The invention adopts such irrigation method as intensive water transfer, water distribution according to the growth cycle of crops, fixed-time water supply, and institution-guiding water saving. The method improves the water level of channels at all levels, raises self-irrigation guarantee rate, saves water, cuts water subsidy, improves water-utilization conditions, and recovers self-irrigation area.

Description

technical field [0001] The invention relates to a water supply dispatching and management system for an irrigation area, in particular to an irrigation method of the "water collection period irrigation" type. Background technique [0002] For many years, in terms of irrigation water management in irrigation areas, the superiors have always adopted the method of allocating the rated flow according to the area, and determining the opening of the gates according to the flow level. Go to each block and gate, and carry out strict guarding. This kind of crowd tactics and mechanical deployment not only caused tension between the upper and lower levels, wasted a lot of manpower and material resources, increased the cost of water management, and more seriously caused In order to avoid chaos in water management, the culvert gates along the canal are pressed when the water level is high and opened when the water level is low, and are frequently switched on and off, which often causes t...

[0002] For many years, in terms of irrigation water management in irrigation areas, the superiors have always adopted the method of allocating the rated flow according to the area, and determining the opening of the gates according to the flow level. Go to each block and gate, and carry out strict guarding. This kind of crowd tactics and mechanical deployment not only caused tension between the upper and lower levels, wasted a lot of manpower and material resources, increased the cost of water management, and more seriously caused In order to avoid chaos in water management, the culvert gates along the canal are pressed when the water level is high and opened when the water level is low, and are frequently switched on and off, which often causes the water level of the main canal and the channels below to go up and down. As a result, more than 40% of the village groups (about 60% of the farmland) set up machine pumps to grab water and lift irrigation in the trunk, branch, and bucket channels to varying degrees, resulting in low irrigation benefits and increased irrigation costs
