Description
Technical field
The present invention relates to agrochemical technical field, specifically a kind of nutritional ingredient proportioning is scientific and reasonable, solubility,
Dissolution velocity is fast, and long-term storage is not likely to produce more nutrient a great number of elements water-soluble fertilizer powder products of caking and preparation method thereof.
Background technology
A large amount of, middle amount and trace element required for crop growth are removed to be supplied at least partially through soil, air and water
In addition, it is most of to need to feed by applying fertilizer.However, common fertilizer product category is single, concentration is low and poorly water-soluble etc.
Cause the nutrient in soil and crop extremely uneven, seriously cause the decline of the yield and quality of crop.Due to me
The existing quality of state peasant is poor, it is desirable to reaches the purpose of balance fertilizing, is only mixed by peasant using existing fertilizer product on the market
Applied after mixed, the nutrient species and proportioning required for crop are can not be guaranteed.The fertilization mode not only increases
Fertilizer production, circulation and the expense for the links such as applying, and add the difficulty of fertilizer application technology, in the technology of shortage
On the premise of guidance, it is difficult to realize scientific and reasonable fertilizing management.Therefore develop a kind of nutrition is balanced, proportioning is scientific and reasonable, into
This low water soluble fertilizer turns into realizes high crop yield, high-quality important channel.
Water-soluble fertilizer be it is a kind of can be with completely soluble polyelement composite fertilizer, it can promptly be dissolved in the water, easily
It is absorbed by crops, and its absorption rate is of a relatively high, is the quick-acting fertilizer that a kind of nutrition is comprehensive, dosage is few, quick.Water
Molten fertilizer dissolves or diluted through water, can be applied to the agricultural technology necks such as fertigation, foliage dressing, soilless culture, seed soaking root dipping
Domain.At present, water-soluble fertilizer product is mainly powder product and fluid product, and most of powder product active constituent content is low, molten
Solution is slow, and plant utilization rate is low, and product stability in prolonged storage is poor, caking easily be present or the moisture absorption is decomposed, and insoluble matter is more,
Shower nozzle and equipment pipeline are easily blocked, modern agriculture can not be adapted to.On the other hand, the fertilizer in being manured into soil for many years only lacks portion
Divide and absorbed by this season crop, remaining 70-80% fertilizer is remained, broken by soil fixing, formation phosphate, nitrate precipitated
The crumb structure of soil is broken, causes soil fertility to decline, cultivation property is deteriorated.Therefore, improved by some new technological means
The solubility of water-soluble fertilizer powder product, and its caking is effectively prevented, soil environment can be added again while fertilizer is applied
To improve, important influence will be produced to China's agricultural development
The content of the invention
The technical assignment of the present invention is in view of the shortcomings of the prior art, there is provided a kind of solubility is high, dissolution velocity is fast, for a long time
Storage is not likely to produce more nutrient a great number of elements water-soluble fertilizer powder products of caking and preparation method thereof, the water-soluble fertilizer proportioning section
It is reasonable to learn, and can meet the nutritional ingredient required for crop production, and and can is changed to soil environment while incorporation of fertilizerin the soil
It is kind.
