Abstract
The invention discloses a plant irrigation water supply system which is characterized in comprising microporous water supply pipes, a water supply control pipe, a pressure regulation valve, and a water supply main pipe. According to the system, a balance is formed among microporous water supply pipe wall resistance, soil water potential gravitational potential, resistance of wet soil ring formed around the microporous water supply pipes, and super-micro water pressure in the microporous water supply pipes. Under plant water consumption effect, balance and imbalance of soil water powder form water supply automatic control of the microporous water supply pipes, and continuous water supply is realized. Because soil water is transferred outwards under a non-saturated status, soil humidity is below field effective humidity. Compared with conventional spray irrigation, drip irrigation and subsurface irrigation, the water supply method provided by the invention is energy-saving, water-saving, highly precise, and fully automatic. Also, the cost of the system is low.
Description
Technical field
This method relates to a kind of plant irrigation water supply system, belongs to agricultural water-saving irrigation technical field.
Background technology
At present, market generally uses negative pressure water supply system, be utilize matric potential and solute potential in soil water potential (soil water potential can be subdivided into matric potential, solute potential, gravitational potential, pressure potential), they are negative values, so be called negative pressure water supply.
Method content
The invention provides a kind of plant irrigation water supply system, it is characterized in that, described system comprises micropore feed pipe, to water management tank, service main, pressure regulator valve; Described system is when top layer placed into the soil by micropore feed pipe, and described system can realize automatically controlling continuous water feeding; Described system is when micropore feed pipe is placed on soil surface, and micropore feed pipe permeable hole is in free discharge and drips state, and described system can not control and continuous water feeding automatically, needs additional controller to realize automatically controlling.
Preferably, described micropore feed pipe is the water-permeable pipe having plastic microporous foaming technique to make.
Preferably, described water management tank of giving is made up of water level controller, filter, ball-cock assembly three part, first be connected on conventional electrical water level controller by water level contact, realize Automatic continuous to supply water, filter water cleaning free from admixture, the ultra micro setting-out position that ball-cock assembly provides micropore feed pipe to need for system.
Preferably, described pressure regulator valve is made up of pressure regulation valve body and adjusting pressuring valve core, and pressure regulation valve body has water inlet and water-flowing trough, and adjusting pressuring valve core has delivery port and water-flowing trough, turns the adjustable overcurrent hydraulic pressure of adjusting pressuring valve core and flow.
Accompanying drawing explanation
Fig. 1 is water supply system composition diagram of the present invention;
In figure:
1, to water management tank; 2, service main; 3, pressure regulator valve; 4, micropore feed pipe.
Embodiment
The plant irrigation water supply system of Fig. 1 composition, will be connected on water source feed pipe to water management tank 1 water inlet, when water source is well pump, what water level controller will control is pump motor.When water source is running water, what water level controller will control is magnetic valve.Micropore feed pipe is the water-permeable pipe having plastic microporous foaming technique to make.Described water management tank 1 of giving is made up of water level controller, filter, ball-cock assembly three part, first be connected on conventional electrical water level controller by water level contact, realize Automatic continuous to supply water, filter water cleaning free from admixture, the ultra micro setting-out position that ball-cock assembly provides micropore feed pipe 4 to need for system.Described pressure regulator valve is made up of pressure regulation valve body and adjusting pressuring valve core, and pressure regulator valve 3 body has water inlet and water-flowing trough, and adjusting pressuring valve core has delivery port and water-flowing trough, turns the adjustable overcurrent hydraulic pressure of adjusting pressuring valve core and flow.
In order to make an arm hydraulic pressure identical, install pressure regulator valve 3 in arm stem, far and near according to arm distance water source, turning pressure regulator valve spool, was water changes of section, to obtain pressure change, was that head and the tail arm hydraulic pressure is substantially identical.Micropore feed pipe 4 will be placed into the soil surperficial 5 cm, requires to water management tank 1 Installation Elevation: by the ball float valve chamber water level given in water management tank 1 to micropore feed pipe water-head, deduct the pipeline loss of flood peak and will be equal to or less than 20 centimetres.
Above embodiment is only for illustration of this method; and the restriction not to this method; the those of ordinary skill of relevant technical field; when not departing from the spirit and scope of this method; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to the category of this method, and the scope of patent protection of this method should be defined by the claims.
