It can be seen that, the technical scheme raw material is excessively complicated, and causes high cost, and the fertilizer impurity for obtaining is excessive.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of special drip irrigation fertilizer of potato, raw material is calculated as with weight point：Phosphorus
It is 20~45 parts of acid, 30~45 parts of potassium sulfate, 20~45 parts of phosphoamide, 1~5 part of trace element, 6~15 parts of moderate-element, thio
3~7 parts of sodium sulphate, 1~4 part of emulsifying agent.
Another object of the present invention provides the drip irrigation fertilizer production method, comprises the following steps：
(1) mix：It is (0.9-1.3) according to mol ratio by phosphoric acid and phosphoamide：1 in stirring-type reaction kettle, and temperature is
70~100 DEG C, control the mixing speed of stirred tank to stir 1~3h of hybrid reaction for 200~220r/min, obtain slurry；
(2) crystallize：Potassium sulfate, sodium thiosulfate, trace element, moderate-element, emulsifying agent are added to (1) stirring simultaneously
In kettle, temperature is maintained at 60~80 DEG C, after stirring 1h, is placed in and is cooled to temperature≤17 DEG C in cooler crystallizer in 13s, and detect
Nutrient content in analysis filtrate, treats that nitrogen component, phosphorus pentoxide composition, the mass ratio of potassium composition are (0.8~1.2)：(0.5
~0.7)：When (1.3~1.5), stopping is crystallized and filtered, and the pore size of filter is 0.6~1.0mm, is adjusted with nitric acid
PH to 6.5~7.0, Water soluble fertilizer is turned into middle and trace element, emulsifying agent and reaction promoter adjustment fertilizer structure is added in filtrate
First finished product；
(3) dry：Just finished product is placed in drier the Water soluble fertilizer that step (3) is obtained, and it is 5 DEG C/min to use programming rate
45-50 DEG C is warming up to, after drying 2~3h, adjustment moisture is 1-3%, you can the drip irrigation fertilizer for improving soil is obtained.
Wherein described trace element is the combination in molybdenum trisulfate, divalence iron chelate, boric acid, zinc sulfate, manganese sulfate.
Wherein described trace element is in parts by weight：0.2~1.1 part of molybdenum trisulfate, divalence iron chelate 0.6~1.2
Part, 0.3~0.9 part of boric acid, 0.6~1.0 part of zinc sulfate, the combination of 0.3~0.8 part of manganese sulfate.
Wherein described moderate-element is calcium sulfate, the combination of magnesium sulfate.
Wherein described moderate-element is in parts by weight 4~8 parts of calcium sulfate, the combination of 2~7 parts of magnesium sulfate.
Wherein described emulsifying agent is hydrophily sucrose ester, and its preparation method is comprised the following steps：
(1) in aliphatic acid, ethanol and the concentrated sulfuric acid being put into reaction kettle of the esterification respectively, and aliphatic acid, ethanol are in mass ratio
1：3 is that reaction temperature is 100~110 DEG C, the excessive ethanol of Distillation recovery, and washs pH to 6.5~7.0, that is, obtain intermediate
Fatty-acid ethyl ester；
(2) in propane diols, fatty-acid ethyl ester, sucrose and potassium hydroxide being put into transesterification reactor respectively, and the third two
Alcohol, fatty-acid ethyl ester, the mass ratio of sucrose are 1：3：3, reaction temperature is 80~90 DEG C, and the reaction time is 6~7h, and reaction terminates
After add citric acid, propane diols is recovered under reduced pressure, washed, add potassium perborate treatment, finally carry out being spray dried to powder,
.
Undissolved particle is dispersed in suspension within water during wherein described hydrophily sucrose ester can make solution, and can be promoted
Immiscible two kinds and above liquid form the emulsified state of stabilization, do not produce flocculation or coalesce, and sealing preserve is for a long time
Also be not in lamination, solve big droplet coalescence change, sedimentation bleed occur in current ambient temperature storage process, separate out crystal,
Even there is demulsifying phenomenon, so as to influence the performance of fertilizer efficiency.
The present invention is using phosphoric acid, potassium sulfate, phosphoamide, sodium thiosulfate, trace element, moderate-element, hydrophily sucrose
Ester is raw material, by rational proportioning, meets potato in growth course, to the demand of N P and K, so as to improve yield；Parent
The composition that aqueous sucrose ester enables each group in raw material immiscible effectively flocks together, and forms emulsified state, is dripped with tradition
Filling mode is compared, will not be because of drip irrigation during, in pipeline formed flocculation or coalesce, so as to cause the blocking of shower nozzle, meanwhile,
The addition of sodium thiosulfate causes that heavy metal in soil ion forms precipitation, coagulation heavy metal in soil with thiosulfate ion
Ion so that the growing environment of potato is effectively guaranteed.
