Research On The Automatic Hydro Control System For Surge Irrigation

It is very necessary and exact to research and development automatic control device which adapt to most of our country's irrigated area channel conveyance and surface irrigation condition and can use surge irrigation in field.It is also the approach of accelerating the developing of the wave and stream irrigation technic and saving water irrigation and it can also achieve the saving water of agriculture.This topic use the surge irrigation technic.It has the characteristic of saving water(it can save 10%-40% water than common channel and farmland irrigation), saving energy,saving fertilizer,incrising production,reducing intensity of labour and reducing the cost of agriculture and so on.It can also use pollution water.salt water or sewage to irrigate,especially in the irrigated area of diversion which from Huanghe River,it can use pollution water to irrigate and needn't water treatment at the condition of aqueduct canal. It has the characteristic of irrigating equally.the speed of pushing fast,no pollution and so on.It is a approach of irrigation that adapt to our country's condition.According to the require of technic parameter of surge irrigation and at the base of analysis and researching,we confirm the better irrigation project.We design water automatic control at first,and then research relevant automatic device by this approach.The topic which accord with our country's recent social and economic condition,operation and water supplying condition of irrigated area makes the automatic hydro control system for surge irrigation which can save water and energy,operate easily,invest economizly,cost little,operate steadily ,and which needn't equip especial device of earthy matevial treatment and outer power,and no pollution and easily accepted by people.The drive of system relys the water from channel itself,in other words.uses the water in the channel but needn't other kinds of drive such as electronic.oil or the drive from the sun,and it don't need outer power device.The topic researches the automatic hydro control system for surge irrigation so the technic parameter of the surge irrigation can be adjusted as we need to satisfy the users' needs in the course of using.
