Description
Technical field
The present invention relates to Liquid Fertilizer technical field, more particularly to a kind of plant nutrient crystalline solid and preparation method thereof.
Background technology
Water soluble fertilizer morphologically shows as solid and liquid.Show as liquid just claims liquid fertilizer, generally also cries
Fluid fertilizer, refers to containing a kind of or more than one nutrient fluid product.These nutrients are complete as solute
Fully dissolved becomes solution in water, is clear liquid type Liquid Fertilizer, and by the effect of suspending agent, the nutrient not being completely dissolved is hanged
Floating on becomes suspension in water, make suspension type liquid fertile.
Liquid fertilizer due to its it is instant, uniform the advantages of, be irrigation equipment fertilising preferred fertilizer.Since it uses property,
Without stirring and dissolving, automation fertilising is very suitable for.Obtained in irrigation technique and the country of automation fertilising popularization, liquid fertilizer
It is widely applied.From in the 1930s, the U.S. is directly applied to crops as liquid fertilizer using liquefied ammonia first and obtains
Success, liquid fertilizer that is produced in USA so far and applying account for the 38% of whole fertilizer, the field almost all liquid of Israel
Fertilizer.Australia, France, Germany, Spain, Romania etc. are all the countries for widely applying liquid fertilizer.
Developmental research of the China to liquid fertilizer starts from the 1950s.The seventies Beijing, Zhejiang, Shandong, Hebei,
Demonstration and popularization are carried out in the ground such as Guangdong, Xinjiang, the detailed statistics that China is also applied without liquid fertilizer at present, tentatively
Estimation, ten thousand t of annual amount of application about 50-60.
China is the country of a water shortage, and water has agricultural production conclusive effect, saves water resource, the rational application of fertilizer
It is the fundamental state policy in China, water-fertilizer integral is trend of the times.And with the popularization of water-fertilizer integral, traditional composite fertilizer is because of it
Dissolution velocity is slow, insoluble matter and harmful ion are more, and industry has been unable to meet the needs of agricultural production, and Water soluble fertilizer is come into being.Pulvis
Nutriment easily blends irregular in Water soluble fertilizer production process, is easily isolated in transportational process and causes unbalanced nutrition, and produces, fortune
Easy moisture absorption caking in defeated and storage, and liquid fertilizer each component be combined with each other, and forms a stable system, nutrients
Matter content is high, even concentration, and nutritional ingredient contained in each drop fertilizer is completely the same in the product of same batch production, nutrition
Equilibrium, effect stability, absorption rate are high, safer, more green, more environmentally friendly, are docked with water-fertilizer integral perfection, market prospects
Wide, main force's on-liquid fertilizer in China's future fertilizer market does not belong to.
In most cases, influenced by solubility and temperature, clear liquid fertilizer nutrient content is relatively low, it has not been convenient to remote fortune
It is defeated, suspension fertilizer is developed for this.Since most of nutrient particle in suspension fertilizer is with existing for suspended state, so suspending
Nutrient content in fertilizer is very high, and the nutrient content of some suspension fertilizers is up to 50%.
The dispersion stabilization of suspension is always a technological difficulties, and suspension type liquid fertilizer is also so.In production, not
Molten nutrient particle is smaller, and the dispersion stabilization of corresponding suspension type liquid fertilizer is better, while during use dilution, solid
Nutrient also dissolves also faster.
Therefore, a kind of nutrient technology for producing fine particle is researched and developed, just into the good suspension of production dispersion stabilization
The key point of type Liquid Fertilizer.
In recent years, the research of ultrasound field extensive chemical process is very active, ultrasonic wave synthesis chemistry, polymer chemistry,
Electrochemistry, extraction and leaching, emulsification and the application during demulsification and cohesion etc. appear in the newspapers repeatly, and experimental study shows, is crystallizing
During introduce ultrasonic wave mainly have the function that adjust crystal size, improve size distribution and shortening crystallization time.
