Abstract
The invention discloses a plant ultra micro-pressure water supply system which consists of microporous water supply pipe, a water supply control valve, a pressure regulating valve and a main water supply pipe and a new water-saving and energy-saving water supply method for irrigation of plants such as crops, vegetables, fruit trees, flowers, nurseries and the like. Continuous water supply of the plant ultra micro-pressure water supply system is realized by balancing the ultra-micro water pressure in the microporous water supply pipe with a resistance force of a pipe wall of the microporous water supply pipe, a gravitational potential of a soil water potential and the resistance force of a wet soil ring which is formed around the microporous water supply pipe by permeated water, and forming automatic water supply control in the microporous water supply pipe by balance and unbalance of water power in the soil. As the soil water is delivered outwards in an unsaturated status, soil humidity is lower than the available field humidity. Compared with the conventional sprinkling irrigation method, the conventional drip irrigation method and the conventional filtration irrigation method, the water supply method has the advantages of energy saving, water saving, high precision, full automation, low cost and the like.
Description
Technical field
The present invention is that relevant plant is given a kind of not only the water saving but also energy-conservation new method waterborne in the river construction: " plant ultramicro pressure water supply system ".
Background technology
Scientific development requires to make full use of various resources, improves utilization ratio, has only noted water-saving method for many years in irrigation, and has ignored the research of power-economizing method in irrigation.The in short supply of the energy put in face of every field, and irrigation is China agricultural large electricity consumer, and irrigating energy-conservation is to be badly in need of solving problem.Plant ultramicro pressure water supply system of the present invention is an exploration achievement.
The Song Yi husband proposed plant negative pressure water supply system in 2005, was to utilize basic mode gesture and solute potential in the soil soil water potential (soil water potential can be subdivided into basic mode gesture, solute potential, gravitational potential, pressure potential), and they are negative values, so be called negative pressure water supply.And plant ultramicro pressure feedwater is to utilize the ultra micro of water in the pipeline to press the gravitational potential in (5-20 centimeter water column) and the soil water potential and the resistance of micropore feed pipe to balance each other, and reaches continuous self water feeding.Plant ultramicro pressure water supply system and plant negative pressure water supply system belong to continuous automatic water supply method together, be to utilize the not only permeable but also resistant characteristic of micropore feed pipe, this water feeding method compare with routine sprinkling irrigation, drip irrigation, infiltrating irrigation have energy-conservation, water saving, precisely, full-automatic, low cost and other advantages, but it is relatively stricter that this water feeding method requires for the land readjustment in pool to final stage, suitable with the paddy field.Because it is to utilize little balance of power to reach energy-conservation.
Summary of the invention
The present invention be utilize the micropore feed pipe, give the water management jar, service main, pressure regulator valve form a kind of plant ultramicro pressure water supply system as shown in Figure 2, this water feeding method compare with routine sprinkling irrigation, drip irrigation, infiltrating irrigation have energy-conservation, water saving, precisely, full-automatic, low cost and other advantages.
Its technical characterictic one: the micropore feed pipe is to make water-permeable pipe by the plastic microporous foaming technique in the plant ultramicro pressure water supply system, utilize ultra micro hydraulic pressure formation balance in the gravitational potential in micropore feed pipe tube wall resistance, the soil water potential, the wet soil loop resistance power that sees through the formation on every side of micropore feed pipe and the micropore feed pipe, under the effect of plant water consumption, feedwater control automatically in the balance of waterpower and the unbalance formation micropore feed pipe in the soil, and realization continuous water feeding, because the soil water is outwards to transmit under unsaturated state, soil moisture is in below the effective humidity in field.
Its technical characterictic two: form in the plant ultramicro pressure water supply system water management jar by water level controller, filter, ball-cock assembly three parts.It finishes three functions, at first is connected on the conventional electrical water level controller by the water level contact, realizes automatic continuous water supply.Second filter makes the water cleaning free from admixture, makes micropore feed pipe operate as normal.The ultra micro setting-out position that the 3rd ball-cock assembly provides the micropore feed pipe to need for system.Guaranteed that the continuous ultra micro of system forces down the energy consumption effect for the water management jar.
Its technical characterictic three: pressure regulator valve is made up of pressure regulation valve body and adjusting pressuring valve core in the plant ultramicro pressure water supply system, can regulate each micropore feed pipe apart from water source distance pressure inequality, makes to reaching even feedwater in the pool.
Its technical characterictic four: plant ultramicro pressure water supply system can be operated under the two states, and when the micropore feed pipe was placed into the soil the top layer, this system can realize controlling automatically continuous water feeding.When the micropore feed pipe was placed on soil surface, micropore feed pipe permeable hole was in the free discharge state that drips, and this system can not control and continuous water feeding automatically, need add controller and realize control automatically.

Embodiment
Plant ultramicro pressure water supply system of the present invention is the little separate unit of feedwater, and for big water supply system, water-carriage system design is routinely only satisfied the water delivery requirement and got final product.And structure among Fig. 2 is pressed in the final stage unit, and stem is changed to Fig. 6 water level valve, and the control of ultra micro setting-out position moves on to the final stage unit, and big system only finishes water delivery and continuous water supply.
By forming plant ultramicro pressure water supply system among Fig. 2, will be connected on the water source feed pipe to water management jar water inlet, when the water source was well pump, what water level controller will be controlled was pump motor.When the water source was running water, what water level controller will be controlled was magnetic valve.In order to make each arm hydraulic pressure identical, in the arm stem pressure regulator valve is installed, apart from the water source distance, turn the pressure regulator valve spool according to arm, made the water changes of section, change to obtain pressure, make in the head and the tail arm hydraulic pressure basic identical.Micropore feed pipe following about 5 centimetres of the top layer of will placing into the soil.High range request is installed for the water management jar:, to deduct the pipeline loss of flood peak and will be equal to or less than 20 centimetres by giving ball float valve chamber water level in the water management jar to micropore feed pipe water-head.
