Background technique
Current irrigation field is made a general survey of, the water efficiency of irrigation of slight irrigation is up to 90% or more, therefore slight irrigation since " 95 "
Technology has obtained very fast development in China, ends national slight irrigation area in 2009 up to 18,000,000 mu, to implement center in 2011
No.1 file and central water conservancy working conference spirit, about 1.95 hundred million mu of national planning and development water-saving irrigation project area, wherein micro-
48,160,000 mu are filled, the new round upsurge for greatly developing water-saving irrigation in China has been risen.Modern micro irrigation technology can be real
Now irrigate the institutional operation with fertilising, it is therefore desirable to inject fertilizer in the pressure pipeline of irrigation system, common note fertilizer dress
It is equipped with pressure differential tank, Development of Venturi Fertilizer Applicator and note fertilizer pump etc., but existing some facilities of these devices are huge, operate not
Just, waste is serious；Some are not easy to adjust, it is irregular to apply fertilizer, and are all difficult to adapt to water-saving irrigation system and require to carry out diversified rich water one
The requirement of integrative management.
Development of Venturi Fertilizer Applicator is made of collapsible tube, expansion long tube, throat, fertilzer sucking pipe.Development of Venturi Fertilizer Applicator and slight irrigation are given
Water system connection installation, control valve when use make hydraulic pressure poor in the forward and backward formation certain pressure of valve, water flow passes through by greatly gradually
Again by the way that by small gradually big pipeline, flow velocity is increased when venturi throat water flow passes through narrow, works as throat after small pipeline
Contraction mouth and expand long saliva stream when caliber water flow velocity reaches a certain level and form negative pressure, the osculum on trunnion side wall is by fertilizer solution
Fertilizer is sucked by tubule out of open fertilizer bucket.Development of Venturi Fertilizer Applicator is because of the features such as its structure is simple, movement-less part, in day
More application is obtained in the small-scale irrigation system such as light greenhouse, arched greenhouse, but Development of Venturi Fertilizer Applicator is inhaled fertilizer and not only needed in the process
In addition use solution bucket so that inconvenient for operation, and that there are pressure loss is big, critical operting differential pressure is high, inhale fertile flow easily with
Operating pressure and fluctuate, fertilizer solution concentration be difficult to control the disadvantages of, be equally also difficult to adapt to trickle irrigation, infiltrating irrigation, it is micro- spray etc. irrigation systems
Requirement to the control of rich water Integrated fertilizer application concentration and small-sized diversified operation readiness.
To solve the above problems, applicant has invented a kind of annular can type sustained release fertilizer applicator, (Chinese utility model is special
Sharp specification CN203301985U).Referring to Fig. 1, it includes a water service pipe D3, water service pipe D3 has water inlet D1 and water outlet

There is discharge opening D22, and is equipped with discharge opening switch D23.
The operation steps that the annular can type is sustained fertilizer applicator are as follows:
1. closing the water source for entering water service pipe D3, discharge opening switch D23 is opened, opens and adds fertile mouth switch D51, by solution pipe
Water in D4 and branch pipe D2 higher than discharge opening switch D23 empties.
2. closing discharge opening switch D23, solution is added from fertile mouth D5 into solution pipe D4 from adding, closes plus fertile mouth switchs
D51。
Pipeline section D8, water flow meeting are irrigated 3. opening water source and water being made to flow into water service pipe D3 from water inlet D1 and flow into through water outlet D6
Gradually slowly take away the solution in solution pipe D4.Water flowing is flowed into when being less than from the water for irrigating pipeline section D8 outflow from water inlet D1
It, also can be by branch pipe D2 from solution pipe D4 while water flow generates upward pressure from the bottom end solution pipe D4 when the water of pipe D3
The pressure that top generates opposite direction makes in solution pipe D4 so that the pressure at both ends in solution pipe D4 be made to be in relative balance state
Solution molecule spread by way of gradually slowly enter water service pipe D3 enter irrigate pipeline section D8, not only can be fine
Ground controls the concentration of solution in water, also can guarantee the strength of fluid for entering water service pipe D3 and irrigation pipeline section D8 from solution pipe D4
It is relatively uniform, to guarantee slow release, uniformity and the high efficiency of fertilising.

Enough fertilizer.
2, the device may be only available for applying solution, i.e. is added in solution pipe D4 and dissolves deployed solution in advance, uncomfortable
It closes and uses soluble solid fertilizer.Itself main reason is that:
Since the solution pipe D4 of the device is directly connected to water service pipe D3 or more, connected surface is usually bigger (no
It is too low then to apply liquid fertilizer concentration), after solution pipe D4 is added in solid fertilizer, it will fall directly into water service pipe, even if in water service pipe
It is dissolved in transmission process, but often fertilizer solution concentration is very big or does not dissolve there are also many solid fertilizers and is not achieved
Preset fertilization effect.
