Abstract
The invention discloses a kind of preparation technology of agriculture level lipopeptid potash fertilizer, the foam solution that lipopeptid fermentation is produced passes through several key links compositions such as centrifugation, crystallization, centrifugation, allotment, dry.The lipopeptid potash fertilizer of preparation can be used for soil improvement, accelerate the biodegradation of soil with organic matter, and the potassium ion contained can promote plant growth；Existing chemical surfactant can be substituted as insecticides adjuvant, especially application effect is more preferable in water aqua type agricultural chemicals.
Description
Technical field
The present invention relates to a kind of preparation method of organic potassic fertilizer, more particularly to a kind of preparation side of agriculture level lipopeptid potash fertilizer
Method.
Background technology
With the fast development and the increasingly increase of the size of population of China's town and country construction, agriculture plantation area just subtracts year by year
It is few, but the demand of agricultural product is constantly increased, agricultural life ginseng is to obtain higher yield, is tied except adjustment plantation is implemented
Structure, is improved outside the measures such as arable land multiple crop index, and a large amount of methods for applying chemical fertilizer are also taken in cultivation, cause arable soil to go out
It is now serious hardened, the problems such as structure is destroyed, permeability is poor, nutrient is lacked of proper care, fertility is low, therefore in the urgent need to changing to soil
It is good.At present, the method for improved soil character is a lot, such as carries out intensive cultivation, green manuring, applying organic manure, efficent rotation
Cultivation step, and soil conditioner is then one of quick effective way for improving soil environment.
Lipopeptid also known as lipopeptide, belong to lipoid containing amino acid, are a kind of biological surfaces that fermentation of bacillus subtilis is produced
Activating agent.Lipopeptid molecule is made up of fat hydrocarbon chain two parts of hydrophilic peptide bond and oleophylic, due to its special chemical composition and
Amphiphilic molecules structure, biodegradability can have kind in the field such as medicine, agricultural, food, cosmetics, microbe oil production
The application prospect wanted.Agriculturally, lipopeptid can be used for soil improvement, accelerate the biodegradation of soil with organic matter；As point
Powder can enable chemical fertilizer and agricultural chemicals using field with distribution, improve efficiency；Existingization can be substituted as insecticides adjuvant
Surfactant is learned, especially application effect is more preferable in water aqua type agricultural chemicals.Potash fertilizer can promote plant growth, it is ensured that various to be metabolized
Being smoothed out for journey, strengthens disease and insect resistance and lodging tolerance etc..The existing lipopeptid product for being applied to agricultural only has lipopeptid sodium salt,
And sodium ion is not so good as potassium ion to plant growth effect, therefore exploitation lipopeptid potash fertilizer has the actual meaning more beneficial to plant
Justice.
The content of the invention
In order to realize the combination of lipopeptid in process of production and sylvite, the invention provides a kind of agriculture level lipopeptid potassium
The preparation technology of fertilizer.
The technical solution adopted for the present invention to solve the technical problems is that the foam solution that lipopeptid fermentation is produced passes through centrifugation, knot
Brilliant, centrifugation, allotment, the several key link compositions of expansion drying.Specially (1) barm liquid is centrifuged：By lipopeptid barm
Liquid adjusts pH9 with potassium hydroxide, and 18000~19000r/min is centrifuged off thalline and large granular impurity, obtains centrifugate；(2) tie
It is brilliant：Centrifugate adjusts pH1~2 with sulfamic acid, stands 24h, goes supernatant and lipopeptid crude product to precipitate；(3) centrifuge：With 18000
~19000r/min is centrifuged, and obtains lipopeptid crude product；(4) allocate：The deionized water of 10~20 times of volumes is added into lipopeptid crude product, is used
Potassium hydroxide adds a certain proportion of potassium sulfate and potassium chloride after adjusting pH7~7.5, stirring and dissolving, and stirring and dissolving obtains lipopeptid potassium
Fertile solution；(5) expansion drying：Lipopeptid potash fertilizer solution expansion drying obtains agriculture level lipopeptid potash fertilizer dry powder.
It is to increase that the preparation technology of agricultural level lipopeptid potash fertilizer of the invention, which includes potassium hydroxide potassium regulation lipopeptid foam solution pH6,
Dissolving of the stuffing peptide in water and the lipopeptid precipitated in foam is set to dissolve again；18000~19000r/min centrifugation be in order to except
The granule foreign for going thalline, gemma and the common slow-speed of revolution to go out；Using sulfamic acid to centrifugate adjust pH1~2, be in order to
Make lipopeptid crystalline deposit, sulfamic acid is conducive to protecting with acid with sulfuric acid, hydrochloric acid identical and small to steel vessel corrosion
Shield machinery；It is to obtain more to crystallization solution centrifugation with 18000~19000r/min centrifuges because lipopeptid fermentation concentration is low
High lipopeptid yield；It is to not increase the impurity such as extra calcium, magnesium, iron, Yi Mian with deionized water and potassium hydroxide dissolving
Infusible precipitate is formed in subsequent treatment, product dissolubility is influenceed；It is to reduce drying time using expansion drying, it is to avoid fat
Peptide is destroyed in long-time heat drying process is crossed；The consumption of lipopeptid is small, and the consumption of potassium is relatively more, forms the ratio of product
For lipopeptid content 5~30%, KCE content 40~60%, sulfuric acid potassium content 30~35%.
The beneficial effects of the invention are as follows by specific PROCESS FOR TREATMENT, realize lipopeptid in process of production and potassium has
Machine is combined, and obtained lipopeptid potash fertilizer good water solubility is nontoxic, and technique is simple, using convenient.
Brief description of the drawings
Fig. 1 is the simple production technological process of present example.
Embodiment
Example 1
