Abstract
The invention relates to an organic-inorganic water-soluble fertilizer and a preparation method thereof. The invention aims at solving the problems that an common organic fertilizer is great in labor intensity in use, inconvenient to use and unobvious in effect, as well as the problems that the soil environment is degraded and the crops quality is reduced caused by the singly using lots of existing inorganic water-soluble fertilizers. The organic-inorganic water-soluble fertilizer is formed by mixing inorganic nutrients, organic nutrients and synergist. And the method comprises the following steps: weighing a water-soluble nitrogen fertilizer, a full-soluble phosphatic fertilizer, a full-soluble potassium fertilizer, synergist and potassium fulvic acid in parts by weight: uniformly mixing the water-soluble nitrogen fertilizer, full-soluble phosphatic fertilizer, the full-soluble potassium fertilizer and the synergist and then grinding, and adding potassium fulvic acid to uniformly mix to obtain the organic-inorganic water-soluble fertilizer. The method is mainly used for preparing the organic-inorganic water-soluble fertilizer.
Description
Technical field
The present invention relates to water-soluble fertilizer of a kind of organic-inorganic and preparation method thereof.
Background technology
Along with the construction macroelement water-soluble fertilizer of irrigating facility has obtained significant progress in China.Because macroelement water-soluble fertilizer has the advantages such as rapid-action, easy to use, liquid manure one, become main fertilizer variety in some region, particularly in vegetables and fruit base concentrated area.Macroelement water-soluble fertilizer is easy to use, and use cost is lower, causes indivedual regions macroelement water-soluble fertilizer to use excessive, causes output more and more lower, and worse and worse, organic content reduces edatope simultaneously, and the problems such as acidifying that harden are day by day serious.The excessive water-soluble fertilizer of using also causes soil-borne disease in soil to take place frequently, and vegetable and fruit quality declines.Application of organic fertilizers is to improve soil organic matter content, and improvement soil acidification and the direct mode such as harden also have obvious effect to improving the anti-adversity ability of plant and the quality of vegetable and fruit.But fertilizer (comprising farm manure, feces of livestock and poultry etc.) all exists usage quantity large, use inconvenience, onset is slow, the problem that may bring heavy metal and microbiotic to pollute simultaneously.Every mu of amount of application of fertilizer that current common feces of livestock and poultry or stalk fermentation make is all more than 500kg, when use, labor capacity is large, and after generally applying as base fertilizer, effect is not remarkable, simultaneously the feces of livestock and poultry of plant is with a large amount of heavy metals, microbiotic and process incomplete germ.So in industrialized agriculture, a large amount of inorganic nutrients abuses and the constant soil productivity of bringing of organic fertilizer application decline at present, crop anti-adversity ability is poor, and under fruit quality, degradation problem becomes increasingly conspicuous.
Summary of the invention
The present invention seeks to solve and use common fertilizer to exist labor capacity larger, use inconvenient, a difficult problem for DeGrain, and the problems that edatope worsens, crop quality declines that the inorganic water-soluble fertilizer of a large amount of use brings separately now, and water-soluble fertilizer of a kind of organic-inorganic and preparation method thereof is provided.
The water-soluble fertilizer of a kind of organic-inorganic is mixed by inorganic nutrients, organic nutrient and synergistic agent, and described inorganic nutrients is made up of full dissolubility nitrogenous fertilizer, full dissolubility phosphate fertilizer and full dissolubility potash fertilizer, and massfraction >=50% of inorganic nutrients in the water-soluble fertilizer of described organic-inorganic; Described organic nutrient is potassium fulvate, and organic massfraction >=10%, massfraction >=10% of humic acids in the water-soluble fertilizer of described organic-inorganic; Described synergistic agent by polypeptide with and amino-oligosacchride mix, and in described synergistic agent, the mass ratio of polypeptide and amino-oligosacchride is 1:(0.2~10); In the water-soluble fertilizer of described organic-inorganic, the massfraction of synergistic agent is 0.1%~10%.
A preparation method for the water-soluble fertilizer of organic-inorganic, specifically completes according to the following steps: one, weigh: take by weight 0.1~5 part of water-soluble nitrogenous fertilizer, 0.1~5 part of full dissolubility phosphate fertilizer, 0.1~5 part of full dissolubility potash fertilizer, 0.01~1 part of synergistic agent and 1~5 part of potassium fulvate; Two, mix: 0.1~5 part of water-soluble nitrogenous fertilizer, 0.1~5 part of full dissolubility phosphate fertilizer, 0.1~5 part of full dissolubility potash fertilizer and 0.01~1 part of synergistic agent are mixed, obtain mixture, then mixture is pulverized, obtain mix powder, again 1~5 part of potassium fulvate added in mix powder and mixed, obtaining the water-soluble fertilizer of organic-inorganic; Synergistic agent described in step 1 by polypeptide with and amino-oligosacchride mix, and in described synergistic agent, the mass ratio of polypeptide and amino-oligosacchride is 1:(0.2~10).
Advantage of the present invention: one, complete water-soluble nitrogen phosphorus potassium total nutrient >=50% in the water-soluble fertilizer of organic-inorganic of the present invention, complete water-soluble organic content >=10%, (Huang) humic acids content >=10%, add appropriate polypeptide and amino-oligosacchride, both met " the water-soluble fertilizer of macroelement " national standard, and met again and have " machine inorganic composite mixed fertilizer " national standard; Two, the water-soluble fertilizer of organic-inorganic of the present invention combines inorganic available nutrient and organic matter, the synergy of performance organic matter and inorganic nutrients, both can provide inorganic nutrients fast for plant growth, Dissolved Organic Matter (DOM) can be provided again, applied once both can provide available nutrient for plant growth, can, for soil provides organic improvement soil, save labor simultaneously; Dissolved Organic Matter (DOM) can arrive root system of plant fast, potassium fulvate, polypeptide and amino-oligosacchride can be nursed one's health soil, and polypeptide, potassium fulvate, amino-oligosacchride can promote the growth of plant root, improve chemical fertilizer utilization ratio, therefore the water-soluble fertilizer of organic-inorganic of the present invention can improve crop anti-adversity ability, reduces soil-borne disease in soil, reduces the negative effect that inorganic nutrients too much brings, promote plant growth, improve crop quality and antibacterial; Three, the water-soluble fertilizer of organic-inorganic of the present invention has overcome degradation problem under the inorganic water-soluble nutrient soil compaction that a large amount of uses cause continuously, acidifying, fertility; Solve that common organic manure application rate is large, labor intensive is large simultaneously, and easily brought a difficult problem for the objectionable impurities such as heavy metal, microbiotic.
