Abstract
The invention relates to a pipeline irrigation oxygenation controller which is designed by utilizing a venturi tube principle. The pipeline irrigation oxygenation controller is provided with a water pipe, wherein a venturi tube section is arranged at the middle part of the water pipe, a one-way air inlet pipe is connected to the lateral wall at the neck mouth of the venturi tube section, a filtering membrane is arranged at an air inlet of the air inlet pipe, and an air regulating valve is arranged at the tail end of the air inlet of the air inlet pipe. The controller can automatically add oxygen (gas) into the water pipe according to the velocity of water flow in the pipeline, enables the oxygen to enter the root part of crops along with water flow, effectively prevents the generation of root oxygen deficiency of crops and increases soil respiration. The invention has low manufacturing cost, scientific and reasonable structure, and convenient operation and use, is suitable for crops in greenhouses, vinyl houses and land fields which adopt different pipe diameters of subsurface drip irrigation devices, membrane drip irrigation devices, infiltrating irrigation devices, and the like and also suitable for fishpond oxygenation, and can implement accurate irrigation and improve energy-saving and water-saving effects as well as the yield and the quality of crops.
Description
Technical field
Content of the present invention belongs to the agricultural irrigation equipment technical field, relating to a kind of pressure conduit irrigates or the pressure conduit delivery equipment, particularly a kind of pipeline irrigation oxygenation control appliance, its product is applicable to operations such as mulch film drip irrigation, underground drip irrigation, infiltrating irrigation and fish pond oxygenation, has energy-conservation, water saving, increases air and oxygen, improves soil respiration, increases fish pond air and oxygen, the effect of increase crop yield.
Background technology
China is the country that relatively lacks of water resource in the world, per capita water resources quantity only is equivalent to world occupancy volume per person's 1/4, many regional lack of water phenomenon in northern China is just even more serious, country quite payes attention to the Application and Development of water-saving irrigation technique all the time for this reason, and wherein mulch film drip irrigation, underground drip irrigation and infiltration irrigation technology have obtained fast development in areas such as Xinjiang at present.Because irrigating is that water is injected in the soil, increase soil moisture content, make soil moisture reach field capacity even the water content that reaches capacity, moisture can make the air in the soil discharge like this, consequently the oxygen content in the soil reduces even is zero, causes the crop root anoxic, and then causes root system death, reduce crop biomass and output, reduce crop quality.Mulch film drip irrigation, underground drip irrigation and infiltrating irrigation are the meticulous irrigation new technologies that has the potentiality of saving water and energy at present most, very suitable in the greenhouse, economic crops such as booth or outdoor cropping fruit tree, vegetables, cotton, a lot of at home areas have all obtained application, but still have some defectives, 1., drip irrigation, infiltrating irrigation and underground drip irrigation belong to little quota high frequency time irrigation technique specifically be summed up as:, cause crop root to be in anaerobic condition equally easily, and then cause crop death, to salinization soil, the crop root anoxic is just even more serious; 2., drip irrigation, infiltrating irrigation and the optimum range of underground drip irrigation technique in many areas be restricted, and cost height, the peasant is reluctant to accept.In sum, how rationally to irrigate, both kept the crop root zone soil moisture that suits, not make it to produce anoxic again be current agronomy worker and irrigate the big problem that the researcher needs to be resolved hurrily.
Summary of the invention
The objective of the invention is to the problem that prior art exists is solved, provide a kind of simple and reasonable, easy for operation, optimum range is wide, cost is low, can rationally irrigate and can not make crop root produce the pipeline irrigation oxygenation controller of anoxic crop, this controller also can increase fish pond air content and oxygen content.
The technical solution that adopts is so for achieving the above object: the pipeline irrigation oxygenation controller that is provided be a kind of utilize the design of Venturi tube principle can adapt to the oxygenation delivery equipment that drip irrigation under the press mold, infiltrating irrigation and underground drip irrigation operation are arranged, it has the water-supply-pipe that a middle part is provided with the venturi pipeline section, on the wall side at the larynx eck place of venturi pipeline section, be equipped with a unidirectional air inlet pipe, air inlet place in air inlet pipe is provided with filter membrane, is provided with Air-regulating valves (air intake control valve) at the air inlet end of air inlet pipe.In the real work, with advancing of this controller water pipe, water outlet end has been connected in presses between the aqueduct, when pressure pipe road current pass through this controller, because the section of body throat reduces, flow velocity strengthens, according to the Venturi tube principle,, cause air outside (oxygen) to enter the body cavum laryngis by air inlet in the terminal negative pressure that produces of throat, be mixed into bubble with high-velocity flow, oxygen (air) is mingled with down at current, enters crop root zone by water dropper, makes crop that oxygen replenishment be arranged in quilt irrigation process all the time, filled up soil owing to irrigate and cause the oxygen (air) that runs off, soil activation and root system microbial activity are improved, increased soil respiration, make the crop root growth can anoxic, thereby crop root is grown to be strengthened, biomass and output increase, and have improved crop quality, have increased water use efficiency simultaneously.Shoal of fish living necessities in the same fish pond are breathed a certain amount of oxygen, and this controller also can add oxygen (air) for the fish pond.The Air-regulating valves that the present invention is provided with at the air inlet place can be regulated oxygen (air) amount that enters pipeline, if do not think oxygenation, can close control valve.In order to prevent that foreign material from entering aqueduct, the place is provided with filter membrane at air inlet.In addition, cause current to penetrate, between the pipeline section of unidirectional air inlet pipe, be provided with spherical non-return valve from air inlet in order to prevent pipeline generation water outlet fault, make air inlet pipe can only air inlet can water outlet, give vent to anger.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
One, the invention provides a kind of control appliance that can arrive aqueduct according to the automatic oxygenation (gas) of pipe flow speed size, it can make oxygen along with current enter crop root, do not reduce pressure of supply water and guarantee that aerating is even, utilize it can effectively prevent the generation of crop root anaerobic condition, increase soil respiration, do not need other power pressing aid during this time, energy-saving effect is obvious;
Two, cost of manufacture of the present invention is low, scientific and reasonable for structure, easy for operation, greenhouse by solar heat, booth and the field crop of equipment such as suitable different tube diameters underground drip irrigation, covering membrane and drop irrigation, infiltrating irrigation are used, also applicable to the fish pond oxygenation, can implement accurately to irrigate, improve energy-conservation and water-saving result, improve crop yield and quality;
Three, the present invention need not any additionaling power, implements to irrigate after only need being installed in system header or arm stem, and cost is low, and is easy to operate.
