Description
【Technical field】
The invention belongs to fertilizer preparation field, and in particular to a kind of preparation method of watermelon germination period special potassium fertilizer.
【Background technology】
Replenished the calcium on Vehicles Collected from Market for watermelon based on the inorganic calciums such as calcium hydroxide, calcium oxide.Although inorganic calcium is cheap, it
Effect is poor, and plant is difficult to be absorbed, and chronic administration, causes soil pH to raise.Substantial amounts of inorganic calcium is with soil erosion, in rivers and lakes
Middle enrichment, is polluted.Therefore in the market be badly in need of it is a kind of easily absorb, effect is good, germination period special potassium fertilizer of not contaminated soil.
This potash fertilizer is a kind of biological active calcium, and biological active calcium refers to biogenic organic calcium, pure natural and unartificial
Synthesis or processing, have that particle is small, it is fast, safe to absorb, without side reaction, beneficial to people and animals and plants absorption.But it is limited to original
Expect source, biological active calcium always can not large-scale industrial production.Seriously limit its use.Possesses the polypeptide of bioactivity
Calcium, it is polypeptide to refer to main chain, possesses the characteristic of biological active calcium, and its source is as obtained from artificial synthesized.
【The content of the invention】
It is an object of the invention to provide a kind of preparation method of watermelon germination period special potassium fertilizer, its concise production process, cost is low,
Environment-friendly, no coupling product produces, and the bioactivity of gained fertilizer is high, while replenishing the calcium, delays the aging of watermelon, possesses aobvious
The effect of increasing production of work, various soil can be applied to.
To achieve these goals, the technical solution adopted by the present invention is：
The preparation method of watermelon germination period special potassium fertilizer of the present invention, comprises the following steps：
A, quantitative calcium oxide and manganese oxide are added in the suspension of polysuccinimide, reaction is hydrolyzed, is had
The polypeptide calcium suspension of standby bioactivity；
B, the acid adding into above-mentioned polypeptide calcium suspension, regulation arrive pH=5-8, obtain the polypeptide calcium clarified solution for possessing bioactivity；
C, aforementioned polypeptides calcium clarified solution is added in fertilizer, obtains watermelon germination period special potassium fertilizer.
In step a, the dosage mol ratio of calcium oxide and polysuccinimide is 0.55:1.
In step a, the dosage of calcium oxide and manganese oxide is 100:(1-5).
In step b, acid used is any one in nitric acid, formic acid, acetic acid or phosphoric acid, and its dosage is to adjust pH as 5-
Untill 8.
In step c, the addition of polypeptide calcium clarified solution is 3 ‰ -3% in fertilizer.
The fertilizer is composite fertilizer, urea, any one in foliar fertilizer, Water soluble fertilizer, bio-bacterial manure, organic fertilizer or Chemical Mixed Fertilizer
Kind.
Beneficial effects of the present invention are：The preparation method of watermelon germination period special potassium fertilizer of the present invention, uses calcium oxide as calcium
Source, in water solution system calcium oxide meet water, discharge heat, help speed up reaction rate, solve calcium hydroxide easily with sky
The problem of carbon dioxide in gas generates precipitation of calcium carbonate；Manganese ion is introduced on polypeptide potash fertilizer, calcium and manganese ion are by main chain
Peptide bond and carboxyl chelating, generate stable five-membered ring, assign polypeptide calcium bioactivity, and while calcium is supplemented to plant, it is given birth to
Thing activity will delay the aging of plant significantly, play significant effect of increasing production.
