Specifically, in step S203, arbitrary two kinds of fertilizer in the first fertilizer group will not be changed in aqueous solution Reaction is learned, such as includes the fertilizer of calcium containing compound in the first fertilizer group, then other fertilizer can be in addition to acid and sulfur-bearing, phosphorus All chemical fertilizer except compound, because the compound meeting of sulfur-bearing, phosphorus and calcium reaction generate the solid such as calcium phosphate of precipitation, sulfuric acid Calcium etc., acid solution can also react with calcium.These reactions can influence the validity of fertilizer component, and sediment can also cause trickle irrigation system System blocks.
It is noted that save equipment cost, chelated iron can also be added to the first fluid reservoir.Chelated iron is in green Color crystalline powder;Iron taste is low, odorless or slightly with mild ferrous metal taste, is highly soluble in water, and chelated iron is as trace element Nutritional agents is used for agricultural, forestry, animal husbandry or other industrial crops.Chelated iron is added in the first fluid reservoir, preparation can be made Nutrient solution be not easy to be fixed in the soil, it is soluble easily in water, and do not dissociate, can be absorbed and used by plants well, also can be with it His solid-state or liquid fertilizer mixing application do not reduce the fertilizer efficiency of any fertilizer without chemically reacting.
In addition, to ensure the adequacy of fertilizer dissolving, 1000 liters of water not dissolved more than 200 kilograms under normal circumstances Fertilizer, i.e. the total weight of all fertilizer is preferably within 200 kilograms in the first fertilizer group.
S204:In the process that the fertilizer in the second fertilizer group is added to the second liquid storage one by one according to the second counterweight sequence In, whether the weight of detection addition in real time reaches the preset weight of this kind of fertilizer, and when detection reaches the preset weight, Send out the first standby signal.
Specifically, in step S204, arbitrary two kinds of fertilizer in the second fertilizer group will not be changed in aqueous solution Reaction is learned, there is the fertilizer of calcium containing compound in the first fertilizer group due to being mentioned in the citing of step S203, then in the second fertilizer Fertilizer in material group can be for all chemical fertilizer other than calcium containing compound, such as phosphate fertilizer, nitrogenous fertilizer, potash fertilizer.Equally, it is guarantor The adequacy of fertilizer dissolving is demonstrate,proved, 1000 liters of water not dissolve the fertilizer more than 200 kilograms, i.e. the second fertilizer group under normal circumstances In all fertilizer total weight preferably within 200 kilograms.
It should be noted that about step S201 to S204, since the quantity of fluid reservoir is two, so using one Electronic scale record is when inserting the weight of fertilizer in fluid reservoir, and it is suitable also to need to preset weighing for the first fluid reservoir and the second fluid reservoir Sequence, for example preset and first the first fertilizer group is added in the first fluid reservoir, then the first fluid reservoir is positioned on electronic scale, After fertilizer in all first fertilizer groups is added in the first fluid reservoir and has recorded the weight of fertilizer of single addition, then carry out The addition of second fluid reservoir fertilizer.
Embodiment of the present invention in terms of existing technologies, by obtain N kinds fertilizer for preparing nutrient solution and The preset weight of each fertilizer, and preset the counterweight sequence of the N kinds fertilizer so that staff can before preparing nutrient solution To get out the amount of various fertilizer to be added, and the N kinds fertilizer is put successively according to counterweight sequence, then to storage Flow container is unified to add fertilizer successively, so operation avoid staff forget to add certain fertilizer or fertilizer of the same race be added to it is more Secondary mistake.It, can be real-time meanwhile during the N kinds fertilizer is added to fluid reservoir one by one according to counterweight sequence Whether the weight of detection addition reaches the preset weight of this kind of fertilizer, and when detection reaches the preset weight, sends out the One standby signal so that staff hears the addition that next fertilizer can be carried out after the first standby signal.Again due to every seed manure Weight needed for material is different, if after a certain fertilizer is added to fluid reservoir completely, compounding device does not send out the When one standby signal or a certain fertilizer are added to fluid reservoir completely not yet, compounding device just has issued first and carries Show signal, then the type for the fertilizer for showing that the weight of the fertilizer added is incorrect or adding is incorrect, and work people Member can check it is mistake caused by which kind of reason according to this.So that staff check be the fertilizer added weight When incorrect, it can continue to add this kind of fertilizer into fluid reservoir until sending out the first standby signal;It is to add checking When the fertilizer type added is incorrect, the addition of this kind of fertilizer can be no longer carried out in follow-up adding procedure, then is subsequently being added The addition for no longer carrying out this kind of fertilizer in the process, addition will not be repeated or leak to add by ensuring that during preparing nutrient solution Fertilizer also avoids inserting the weight of fertilizer in fluid reservoir and mistake occurs.
Third embodiment of the present invention is related to a kind of compounding method.Present embodiment is in second embodiment Basis on done further improvement, specifically the improvement is that:In the present embodiment, the fluid reservoir further includes storage The third fluid reservoir for having acid solution, by last kind of fertilizer in the first fertilizer group be added to first fluid reservoir it Afterwards, the first pH-value for detecting solution in first fluid reservoir, sends out when first pH-value is between 4.5 to 6 Second standby signal;After last kind of fertilizer in the second fertilizer group is added to second fluid reservoir, detection Second pH-value of solution in second fluid reservoir sends out third standby signal when second pH-value is less than 4, controls Solution in first fluid reservoir flows out with identical speed and is formed mixed solution with the solution in second fluid reservoir, Control acid solution in the third fluid reservoir and flow into the mixed solution, the mixed solution third pH-value between 5.2 The acid solution controlled when between to 5.8 in the third fluid reservoir stops outflow.The detailed process of present embodiment as shown in figure 3, Including:
S301:Obtain the default weight of the first fertilizer group and the second fertilizer group and each fertilizer for preparing nutrient solution Amount.
S302:The first counterweight sequence of default first fertilizer group and the second counterweight sequence of the second fertilizer group.
S303:In the process that the fertilizer in the first fertilizer group is added to the first liquid storage one by one according to the first counterweight sequence In, whether the weight of detection addition in real time reaches the preset weight of this kind of fertilizer, and when detection reaches the preset weight, Send out the first standby signal.
Step S301 to step S303 is roughly the same to step S203 with step S201, in order to avoid repeating, herein no longer It repeats.
S304:The first pH-value for detecting solution in the first fluid reservoir, sends out when the first pH-value is between 4.5 to 6 Go out the second standby signal.
Specifically, in step s 304, the first pH-value of solution in the first fluid reservoir of detection, PH can be counted by PH Meter is a kind of common instrument and equipment, is mainly used to the pH value of accurate measurement liquid medium, mixes corresponding ion selection Electrode can also measure ion electrode current potential MV values, pH meter be widely used in environmental protection, sewage disposal, scientific research, pharmacy, fermentation, The fields such as chemical industry, cultivation, tap water.The instrument is also that indispensable examine in food factory, drinking water administrative office in a factory QS, HACCP certification sets It is standby.During the use of PH meters, the rubber above electrode should be peeled, aperture is made to be exposed, otherwise when being analyzed, Negative pressure is will produce, causes Klorvess Liquid that cannot pass through glass ball bulb and carries out ion exchange with detected solution, measurement can be made Data are inaccurate.Rubber should be restored after being measured, seal aperture.Electrode should be immersed in 3mol/L after distilled water cleans It,, should be in 3mol/L if electrode has been lost in using preceding discovery protection liquid with the moistening for keeping ball electrode to steep in Klorvess Liquid A few hours are impregnated in Klorvess Liquid, so that electrode reaches best measuring state.
If the first pH-value is higher than peak demand value 6, soda acid can be adjusted by adding acid solution into the first fluid reservoir Value, makes it between 4.5 to 6, due to calcium meeting and phosphatase reaction, precipitation is generated, so should not add phosphorus in the first fluid reservoir Acid adjusts pH-value, can be adjusted with a concentration of 68% nitric acid.
S305:In the process that the fertilizer in the second fertilizer group is added to the second liquid storage one by one according to the second counterweight sequence In, whether the weight of detection addition in real time reaches the preset weight of this kind of fertilizer, and when detection reaches the preset weight, Send out the first standby signal.
S306:The second pH-value for detecting solution in the second fluid reservoir sends out third prompt when the second pH-value is less than 4 Signal.
It specifically,, can be by adding acid into the second fluid reservoir if the second pH-value is higher than 4 in step S306 Liquid adjusts pH-value, due to fertilizer in the second fluid reservoir not calcium containing compound, it is possible to be adjusted with phosphoric acid.
It should be noted that chelated iron meeting and phosphorus reaction when pH-value is less than 4.5 or higher than 6, destroy the effective of fertilizer Ingredient, so chelated iron cannot be added in the second fluid reservoir.
