Fertilizer-pesticide double-effect double-chelated multi-element multi-functional medical stone liquid fertilizer and preparation method thereof

Abstract

The invention discloses a fertilizer-pesticide double-effect double-chelated multi-element multi-functional medical stone liquid fertilizer and a preparation method thereof. The liquid fertilizer is prepared by compounding and mixing raw powder of medical stones, soluble silicon, limestone, compound amino acid, ammonium phosphate, urea, potassium oxide, magnesium sulfate, ferrous sulfate, manganese sulfate, copper sulfate, boracic acid, zinc sulfate, ammonium molybdate, selenium powder, poly(potassium aspartate) and the like, a botanical pesticide composition agent prepared from ricin, veratrine, herba asari volatile oil, rotenone, clausena dunniana essential oil, coptis chinensis alkaloid and glycyrrhizic acid, an amino-oligosaccharin bacteriostatic agent, gibberellin, alum, DA-6, EDTA, hydrochloric acid, ethyl alcohol and the like. The preparation method of the liquid fertilizer comprises the steps that the raw materials are mixed and compounded to generate a hot-melting reaction with aqueous diluted hydrochloric acid, the materials and urea are added with water, mixed dissolving is conducted by increasing the temperature to 100 DEG C, then the reactants and the botanical pesticide composition agent are diluted, mixed, compounded and foamed to be mixed with synergistic liquid, the materials are heated until the temperature is 80 DEG C to 120 DEG C and dissolved and mixed, solid-liquid separation is conducted to remove residues, the obtained liquid is delivered into the reaction kettle to be subjected to secondary chelation with EDTA and DA-6, and then the high-concentration suspension type liquid fertilizer is prepared in a mixed mode.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a medical stone fertilizer double-effect double-chelation multi-element multifunctional liquid fertilizer and a preparation method thereof. Background technique [0002] At present, in my country's agricultural production and planting, there are common problems such as simple fertilizer varieties and nutrient element structure, incomplete element ratio, unbalanced fertilizer supply, simple and extensive fertilizer application technology, low fertilizer efficiency utilization rate, and relative application of chemical fertilizers and pesticides in the field. Disjointed, almost no integrated agricultural products with fertilizers and medicines, high field management costs, low effects, large fertilizer and medicine residues, soil compaction, serious environmental pollution, declining fertilizer supply capacity, and rising planting costs year by year, while the output and quality of agric...

Problems solved by technology

[0002] At present, in my country's agricultural production and planting, there are common problems such as simple fertilizer varieties and nutrient element structure, incomplete element ratio, unbalanced fertilizer supply, simple and extensive fertilizer application technology, low fertilizer efficiency utilization rate, and relative application of chemical fertilizers and pesticides in the field. Disjointed, almost no integrated agricultural products with fertilizers and medicines, high field management costs, low effects, large fertilizer and medicine residues, soil compaction, serious environmental pollution, declining fertilizer supply capacity, and rising planting costs year by year, while the output and quality of agricultural products are declining year by year , a single solid fertilizer product and a simple foliar fertilizer can no longer meet the needs of increasing production and income in agricultural planting in our country
