Description
Technical Field
The invention belongs to the field of agricultural fertilizers, and particularly relates to a mineral source fulvic acid slow-release fertilizer and a preparation method thereof.
Background
In recent years, the harm of underground pests such as grubs, wireworms, cutworms and the like is increased year by year, and particularly crops such as peanuts, potatoes and the like are seriously damaged by the underground pests. The loss caused by the grubs harming crops such as peanuts, potatoes and the like in China every year reaches more than 20 percent, even the grubs are not harvested, and the quality of the peanuts, the potatoes and the like is reduced. For the prevention and control of underground pests, chemical methods such as toxic soil, toxic bait, medicament root irrigation, medicament seed dressing and the like are generally used, but the large amount of chemical pesticides is used, so that the pests have drug resistance, the prevention and control effect is reduced, the problems of medicament residue and environmental pollution are caused, the health of people and livestock is seriously threatened, and the effective chemical utilization rate is low. In the traditional planting technology, the pesticide for preventing and controlling the soil insects is applied in a ditch, a hole or mixed with water to irrigate roots, so that the labor intensity and labor frequency of farmers are increased, and the utilization rate of the active ingredients of the pesticide is not high; meanwhile, in the traditional agricultural production technology, the fertilizer and the insecticide are applied separately, and the method of using the insecticide and the fertilizer for two times or more is needed, so that the labor intensity and the labor frequency of farmers are increased, and the agricultural development is not facilitated.
Fulvic acid is the most active component in humic acid, has small molecular weight, is easy to dissolve in water, has good flocculation resistance and is widely applied in the field of fertilizers. The fulvic acid is a soil conditioner, a plant growth regulator, a synergist and a slow release agent of an inorganic fertilizer. The fulvic acid is reported to obviously improve the absorption and utilization rate of nitrogen, phosphorus and potassium for crops. The utilization rate of the phosphate fertilizer is improved by 8.4 to 44.1 percent; the utilization rate of the potash fertilizer is improved by 17.7 percent; the utilization rate of the catalyst is respectively improved by 3.37 times and 11.80 times when the catalyst is mixed with ammonium bicarbonate and ammonia water for use. The sources of the fulvic acid mainly comprise two types, one type is extracted from straws and the like after biological fermentation, and the straw is called biochemical fulvic acid; one is mineral-derived fulvic acid, which is called mineral-derived fulvic acid, and the two have no significant difference in use effect, but the mineral-derived fulvic acid has wide sources and easily available materials.
The prior medicament for preventing and controlling grub, cutworm, mole cricket and other underground pests is generally an organophosphorus pesticide, the organophosphorus pesticide is unstable and easy to decompose and lose efficacy under alkaline and water conditions, and soil microorganisms can accelerate the decomposition of organophosphorus and other chemical pesticides. The superposition of conditions such as acidity, alkalinity, soil moisture, soil microorganisms and the like leads to the greatly shortened lasting period of the chemical agent, generally only a few days, thereby causing the unsatisfactory control effect on the soil insects. And related medicaments are repeatedly used for a long time or are not scientifically used, so that underground pests such as grubs, cutworms, mole crickets and the like are abused to cause disasters, the dosage is increased, and the prevention and treatment cost is greatly increased. The seedling stage to the flowering stage of the peanuts are the key stages of peanut production, and the scientific application of water, fertilizer and pesticide in the period directly influences the yield and quality of the peanuts or potatoes.
In conclusion, the research and development of the slow-release fertilizer with the insecticidal effect has important significance.

Further, the polyvinyl alcohol is polyvinyl alcohol 600.
Further, the fulvic acid is mineral fulvic acid.
Further, the pesticide is phoxim and/or carbaryl.
The preparation method of the mineral source fulvic acid slow-release fertilizer is characterized by comprising the following steps of:
(1) mixing urea, monoammonium phosphate, ammonium sulfate, potassium carbonate, potassium nitrate, insecticide, indoleacetic acid and part of fulvic acid, uniformly stirring, granulating and drying to obtain a fertilizer core;
(2) mixing polyvinyl alcohol and the rest fulvic acid, heating to 60-80 ℃, uniformly stirring to obtain a coating liquid, adding the fertilizer core obtained in the step (1), coating and drying to obtain the mineral source fulvic acid slow release fertilizer.
Further, the mass ratio of the fulvic acid in the step (1) to the fulvic acid in the step (2) is 1-2: 1.
Further, the particle size of the fertilizer core in the step (1) is 0.5-2 mm.
Phoxim belongs to an efficient, low-toxicity and broad-spectrum thiophosphate organophosphorus insecticide, which was developed by German Bayer company in 1965 and belongs to a large-tonnage pesticide variety at present. Phoxim has wide insecticidal spectrum and strong knock-down force, mainly takes contact killing and stomach poisoning effects, has no systemic effect, and is very effective on lepidoptera larvae. The pesticide has short residue period and less residue danger due to unstable light and quick decomposition in the field, and is suitable for being applied to soil to control underground pests.
Carbaryl, also known as carbaryl, belongs to N-methyl carbamate pesticides; synthesized in 1953, commercialized and industrially produced by Union carbide in the United states in 1958; the pesticide is the first commercial variety in carbamate pesticides and is also the variety with the largest yield, and the annual sales amount is more than 1 hundred million dollars at present; the application range is wide: it is effective against 160 kinds of pests on 65 kinds of grain and fiber crops. Carbaryl has contact poisoning and stomach poisoning effects, and has slight systemic property. Can be used for preventing and treating pests of fruits, vegetables, cotton, rice, soybean, etc., such as Lepidoptera, Diptera, Cuicoides, Blatta Seu Periplaneta, mosquito, etc.
