P2O5、K2O content is 120-120-120 (unit g/L), and the Liquid Fertilizer after blending is not saltoutd, storage not stratified, inspection in more than 30 days
Survey method is with embodiment one.
High-concentration suspension type liquid potash fertilizer obtained by the present embodiment three, N, P in liquid composite fertilizer2O5, K2O contents be
120-120-120 (unit g/L), in greenhouse cucumber (cucumber variety：Tianjin win) on carry out fertilizer test, method of application is chased after for drip irrigation
Fertilizer, control fertilizer is market purchasing chemical fertilizer (Run Zi Chemical Co., Ltd.s of Zouping County, containing 20%N, 20%P2O5, 20%K2O),
Fertilizer treatment is carried out using equal nutrient dose.To the products measure yield and chlorophyll content of different disposal.This product increases
Produce effect substantially, be compared to control fertilizer, volume increase 7.72%, chlorophyll content improves 9.21%.
Comparative example one
Comparative example one is the experiment that inventor did during high-concentration suspension type potash fertilizer is researched and developed, but because product contains
The difference of amount and technique, the technique effect not obtained, its specific embodiment is as follows：
100 parts of meters, are formulated as follows in an amount：8 parts of potassium chloride, 8 parts of potassium nitrate, 1 part of potassium sulfate, 0.5 part of potassium fulvate, first
46 parts of sour potassium, 4 parts of ethylene glycol, 3 parts of calgon, 4 parts of sodium bentonite, 0.2 part of X-7050,0.3 part of CHS-5, xanthan
0.15 part of glue, 24.85 parts of water.
The preparation method of high-concentration suspension type liquid potash fertilizer, comprises the following steps described in this comparative example one：
1) water 24.85kg is weighed, is added in reactor A, under the conditions of high-speed stirred, sequentially add potassium chloride 8kg, nitric acid
Potassium 8kg, potassium sulfate 1kg, potassium fulvate 0.5kg, potassium formate 46kg, ethylene glycol 4kg, calgon 3kg, sodium bentonite
4kg, agitator speed is 1000 revs/min, is persistently stirred 60 minutes, is all dissolved to above material, forms homogeneous liquid；
2) in the liquid in reactor A being pumped into sand mill, it is sanded 60 minutes at a high speed, sand mill rotating speed is 2500 revs/min
Clock, all dissolves to above material, forms homogeneous liquid；
3) in the liquid in sand mill being pumped into reactor B, under the conditions of high-speed stirred, sequentially add, X-7050
0.2kg, CHS-5 0.3kg, xanthans 0.15kg, agitator speed are 1000 revs/min, are persistently stirred 40 minutes, to the above
Material all dissolves, and forms homogeneous liquid；
4) liquid in reactor B is filtered through 200 mesh filter screens, is pumped into storage tank, stand 24 hours.
Potassium oxide content measure, storage stability detection are carried out to finished product using the identical method of embodiment one and is saltoutd
And lamination observation.
, after normal temperature stands storage 7 days, there is flocculation and delamination in the high-concentration suspension type liquid potash fertilizer obtained by this comparative example one
There is clear water layer with bottom in phenomenon, upper strata, and syneresis rate has exceeded 40%, does not meet product quality requirement.Compare embodiment
First, embodiment two and embodiment three, potassium salts content improve, prepare finished product of the present invention when, by sylvite first same antifreezing agent, dispersant with
And suspending agent mixing, the stability of final obtained product can be influenceed, it is undesirable to show as syneresis rate, flocculation and delamination occurs
Phenomenon.
In sum, the Liquid K for being prepared using suspension type liquid potash fertilizer of the invention and the method for the present invention
Fertilizer, because storage stability is high, and in the absence of saltouing and lamination, therefore can be administered alone, it is adaptable to be sprayed to fill etc. and set
Agricultural is applied, not blocking pipeline.Simultaneously as its potassium salts content of the suspension type liquid potash fertilizer of present invention offer is high, can be with urea
Ammonium nitrate solution, the blending of oligomeric phosphoric acid ammonium salt solution are used, and prepare suitable according to planting area soil regime, crop species and growing state
Suitable nutrient formulation liquid fertilizer, can improve the effect of increasing production of crop, it is adaptable to fertilization compositions based on earth measurement, can be widely popularized.
And the preparation method process is simple that the present invention is provided, low production cost, it is not necessary to pressurized, heated, consume energy few, do not produce waste water
Waste gas, to stablize homogeneous liquid, nutrient content is high, and low temperature is not saltoutd, and stores not stratified for a long time, does not precipitate for the product of preparation,
It is suitable to mass produce and promotes.
The above is only preferred embodiments of the invention, is not the limitation for making other forms to the present invention.Should
Point out, for those skilled in the art, can be made alterations based on technology contents disclosed in the present application
Or it is modified to its equivalent integers.On the premise of without departing substantially from design of the invention and spirit, what the present invention was carried out any changes
Change or modification belong to the protection domain of technical solution of the present invention.
