Description
One, technical field
The present invention relates to a kind of agrotechnique and a kind of agricultural machinery.
Two, background technology
In recent years, along with the development of economy and society, the water resource day of China is existing deficient, and in order to using water wisely, country widelys popularize drip irrigation technique at agriculture field.But, how Crops in Applying Fertilizer is given under condition of drip irrigation? current prior art directly puts in an iron flask by pulverous chemical fertilizer, there is the outlet of a tubulose lower end of iron flask, the sidewall of drip irrigation main pipeline there is a hole matched with this outlet, be inserted in hole by this outlet, when there being current out-of-date in droping irrigating pipe, chemical fertilizer will be washed in water, arrive the root of crop together with water, reach the object of fertilising.Said method has following shortcoming: one, the easy blocking pipe of chemical fertilizer granule, causes local not irrigate and to apply fertilizer; Two, the particle of chemical fertilizer varies, and the speed entered in droping irrigating pipe is sometimes fast and sometimes slow, so the content of chemical fertilizer is uneven in water, causes unevenness of application, cannot carry out Tree Precise Fertilization; Three, for indissoluble fertilizer such as potassium sulfate, diamino, superphosphate, the fertilizer dissolved in water is few, is difficult to the needs meeting plant growth; Fertilising process is time-consuming, effort, also waste fertilizer.
Three, summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the object of this invention is to provide a kind of not blocking pipe, fertilising evenly, fertilizing amount is sufficient, save time, laborsaving, fertigation method and the fertigation equipment of economizing fertilizer.
To achieve these goals, fertigation method of the present invention is: first chemical fertilizer and water mixed and stir, making the saturated aqueous solution of chemical fertilizer, then being injected in droping irrigating pipe by this solution.
Fertigation equipment for above-mentioned fertigation method mainly comprises agitator tank, agitator and fluid reservoir.Agitator is made up of circulation pipe, stop valve, high-pressure pump, water inlet pipe, shower nozzle, one end of circulation pipe is arranged on the sidewall of agitator tank lower end, the other end is connected with stop valve, the other end of stop valve is connected with high-pressure pump, the water side of high-pressure pump is connected with water inlet pipe, one end of water inlet pipe is connected with water source by water intaking valve, and the other end of water inlet pipe enters in agitator tank, and end is provided with shower nozzle.On the sidewall of agitator tank, be fixed with outlet pipe, on outlet pipe, be provided with outlet valve, the other end of outlet pipe leads to fluid reservoir.Be shaped with scum pipe in the lower end of agitator tank, scum pipe is provided with residual cake valve.Fluid reservoir is provided with drain pipe, and the lower end of drain pipe is provided with filter screen, and the upper end of drain pipe is connected with Pump for giving-out, and the delivery port of Pump for giving-out is connected with droping irrigating pipe.
Have employed technique scheme, first water and fertilizer are joined in agitator tank during fertilising, start agitator and stir fully, until fertilizer no longer dissolves, the saturated aqueous solution of the fertilizer obtained is imported in fluid reservoir, then is injected in droping irrigating pipe by Pump for giving-out.Owing to there is no the solid particle of fertilizer in pipeline, so pipeline can not block.Due to the saturated aqueous solution that fertilizer concentration of trickling in pipeline is identical everywhere, so it is even, sufficient to apply fertilizer, and practicable Tree Precise Fertilization; Owing to no longer needing frequent dredging pipeline, fix a breakdown, thus it save time, laborsaving, economize fertilizer.
In fertigation equipment, be made up of the circulation bypass of an aqueous fertilizer solution circulation pipe, stop valve, high-pressure pump, water inlet pipe, shower nozzle, aqueous fertilizer solution flows out from circulation pipe, successively through stop valve, high-pressure pump, water inlet pipe, finally penetrated by shower nozzle.Due to high-pressure pump of having connected in circulation bypass, add the hydraulic pressure in circulation bypass, make aqueous fertilizer solution from shower nozzle injection at a high speed, run into back reflection bottom agitator tank, form turbulent flow, fertiliser granulates is done without Zhang Yundong in agitator tank, accelerates the speed of the dissolving of fertilizer.
Four, accompanying drawing explanation
Fig. 1 is the structure diagram of fertigation equipment.
Five embodiments
Below in conjunction with the drawings and the specific embodiments, the present invention is further illustrated.
Fertigation equipment mainly comprises agitator tank 1, agitator and fluid reservoir 8 in FIG, and agitator is made up of the circulation pipe 12 be arranged on agitator tank 1, stop valve 13, high-pressure pump 14, water inlet pipe 16, shower nozzle 3.One end of circulation pipe 12 is arranged on the sidewall of agitator tank 1 lower end, and the other end is connected with stop valve 13, and the other end of stop valve 13 is connected with high-pressure pump 14, and the water side of high-pressure pump 14 is connected with water inlet pipe 16; One end of water inlet pipe 16 is connected with water source by water intaking valve 15, and the other end of water inlet pipe 16 enters in agitator tank 1, and end is provided with shower nozzle 3; On the sidewall of agitator tank 1, be fixed with outlet pipe 7, on outlet pipe 7, be provided with outlet valve 6, the other end of outlet pipe 7 leads to fluid reservoir 8.Be shaped with scum pipe 4 in the lower end of agitator tank 1, scum pipe 4 be provided with residual cake valve 5; Fluid reservoir 8 is provided with drain pipe 9, and the lower end of drain pipe 9 is provided with filter screen 11, and the upper end of drain pipe 9 is connected with Pump for giving-out 10, and the delivery port of Pump for giving-out 10 is connected with droping irrigating pipe.
Outlet valve 6 and stop valve 13 is first closed when starting working, open water intaking valve 15, water enters agitator tank 1 by water inlet pipe 16, shower nozzle 3, water fills up rear closedown water intaking valve 15, then fertilizer is added from charge door 17, open stop valve 13, start high-pressure pump 14, the water now in agitator tank 1 circulates via circulation pipe 12, stop valve 13, high-pressure pump 14, water inlet pipe 16, shower nozzle 3 successively.Due to high-pressure pump 14 of having connected in circulation bypass, add the hydraulic pressure in circulation bypass, make aqueous fertilizer solution from shower nozzle 3 injection at a high speed, run into back reflection bottom agitator tank 1, form turbulent flow, fertiliser granulates is done without Zhang Yundong in agitator tank 1, accelerates the speed of the dissolving of fertilizer.When fertilizer no longer dissolves, close down high-pressure pump 14, close stop valve 13, open outlet valve 6, aqueous fertilizer solution flows to fluid reservoir 8 from outlet pipe 7, opens Pump for giving-out 10, is injected in droping irrigating pipe by saturated aqueous fertilizer solution by the delivery port of Pump for giving-out 10.
Except above-mentioned embodiment, the present invention can also have some to change, and such as agitator can with traditional electromotor driven rotary leaf structure, and even can also use the free-hand stirring of waddy, all these changes, all fall among protection scope of the present invention.
