Description
Technical field
The present invention relates to a kind of composite fertilizer with pesticide and preparation method thereof.
Background technology
In agriculture production, agricultural chemicals and fertilizer are guaranteeing on crop yield, to play requisite effect.The biology of agricultural chemicals energy kill pests, fungi and other growth that harms the crops; Fertilizer can provide plant necessary nutrition, and improves the soil property of soil.Along with scientific and technological development, not only had to kill and pressed down diseases and pests of agronomic crop but also can become main research direction for farm crop provide the functional composite fertilizer with pesticide of nutrition.
At present, composite fertilizer with pesticide is that fertilizer is major ingredient, adopts coating method that agricultural chemicals is wrapped in to fertiliser granulates appearance.The major ingredient adopting is generally nitrogen, phosphorus, potassium macroelement fertilizer, ignored the use of trace element fertilizer, and for farm crop, no matter macroelement or trace element are of equal importance, when trace element is not enough, not only affect the output of farm crop, and lower the quality of farm crop, even farm crop also there will be pathology.Therefore, peasant when using medicine fertilizer, need add trace element fertilizer to farm crop according to the needs of farm crop, and manual stirring is time-consuming, and, easily cause secondary pollution; And farm crop are few to micro-demand, during mixing, be difficult for stirring, easily cause farmland micro-fertile local excessive or not enough, affect output.
CN101906001A discloses " the fertile preparation method of a kind of medicine fertilizer and application thereof, particle formulation medicine fertilizer and powder-type medicine ", and the method is by solvent, Avrmectin, Volaton and/or Chlorpyrifos 94, tensio-active agent mixed dissolution, is mixed with mother liquor; By mother liquor mix with macroelement fertilizer, trace element fertilizer, sorbent material, carrier, granulation, obtain particle formulation medicine fertile.This preparation method's technique is simple, and condition is easily controlled, and is suitable for suitability for industrialized production.Its shortcoming is: adopt the method for mixing granulation, the slow release effect of agricultural chemicals is undesirable, and in granulation process, needs to dry, and easily causes a large amount of farm chemical ingredients to vapor away, and affects the fertile insecticidal effect of medicine, to environment, affects direct labor healthy.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of composite fertilizer with pesticide and preparation method thereof, and fertilizer nutritive ingredient is abundant, in production process without hyperthermia drying, can effectively guarantee farm chemical ingredients, safety and environmental protection, is applicable to suitability for industrialized production.
Technical solution of the present invention is:
A composite fertilizer with pesticide, percentage composition meter is comprised of following composition by weight:
Nitrogen-phosphorus-potassium compound fertilizer 30%～40%;
Provado 22%～30%;
Difenoconazole 0.1%～1%;
Bacillus thuringiensis 0.1%～0.5%;
Coating agent 5%～8%;
Boron magnesium slag 24%～36%.
Described coating agent is that mean particle size is 100 order～150 object gypsum.
Meter by weight, in described nitrogen-phosphorus-potassium compound fertilizer, nitrogenous fertilizer is that 15 parts～22 parts, phosphate fertilizer are 10 parts～12 parts of 5 parts～8 parts, potash fertilizer.
In described boron magnesium slag, the quality percentage composition of boron trioxide is 3.0%～3.2%, magnesian quality percentage composition is 22%～24%, the quality percentage composition of calcium oxide is 4.0%～4.2%, the quality percentage composition of silicon-dioxide is 9.2%～9.5%, the quality percentage composition of ferric oxide is 1.8%～2.1%, the quality percentage composition of sulphur is 0.2%～0.3%, and the quality percentage composition of cupric oxide is 0.3%～0.5%, and the quality percentage composition of molybdenum is 0.3%～0.4%.
A preparation method for composite fertilizer with pesticide, its concrete steps are:
Boron magnesium slag powders is broken to 80 order～100 orders and obtains boron magnesium slag particle, percentage composition meter by weight, after 0.1%～0.5% Bacillus thuringiensis is joined and is mixed in 24%～36% boron magnesium slag particle, mix with 30%～40% nitrogen-phosphorus-potassium compound fertilizer particle, obtain boron magnesium slag and nitrogen-phosphorus-potassium compound fertilizer composite grain, 22%～30% Provado and 0.1%～1% difenoconazole are added to the water and are stirred, evenly be sprayed at the surface of boron magnesium slag and nitrogen-phosphorus-potassium compound fertilizer composite grain, and carry out coating with 5%～8% coating agent, sieve, make composite fertilizer with pesticide particle.
Meter by weight, in described nitrogen-phosphorus-potassium compound fertilizer, nitrogenous fertilizer is that 15 parts～22 parts, phosphate fertilizer are 10 parts～12 parts of 5 parts～8 parts, potash fertilizer.
Described coating agent is that mean particle size is 100 order～150 object gypsum.
In described boron magnesium slag, the quality percentage composition of boron trioxide is 3.0%～3.2%, magnesian quality percentage composition is 22%～24%, the quality percentage composition of calcium oxide is 4.0%～4.2%, the quality percentage composition of silicon-dioxide is 9.2%～9.5%, the quality percentage composition of ferric oxide is 1.8%～2.1%, the quality percentage composition of sulphur is 0.2%～0.3%, and the quality percentage composition of cupric oxide is 0.3%～0.5%, and the quality percentage composition of molybdenum is 0.3%～0.4%.
The effective content of described Bacillus thuringiensis is 8000IU/ milligram～16000IU/ milligram.
Beneficial effect of the present invention:
1, in boron magnesium slag, contain the required trace element of abundant plant-growth, for fertile production of medicine, turn waste into wealth, reduced the be rivals in a contest pollution of environment of slagheap, boron magnesium slag being mixed to the medicine fertilizer making with nitrogen-phosphorus-potassium compound fertilizer and agricultural chemicals can provide plant-growth required nutrient, single-dose application can reach requirement, alleviated peasant's labour intensity, saving of work and time, has avoided Multiple Pesticides and fertilizer to puddle the secondary pollution causing.
2, Provado and difenoconazole compound use, control wheat aphid and smut are had a significant effect, add Tribactur all to there is specific strong cytotoxicity to above and below ground insects such as the arthropodss such as lepidopteran, Coleoptera, Diptera, Hymenoptera, Homoptera and Plant nematode, acarians, thereby make more wide spectrum of insecticidal effect, the dual function with desinsection and sterilization, and safe and harmless to nontarget organism people and animals etc.
3, boron magnesium slag is acid, with soil neutralization, can play the effect of Porous soil, boron magnesium slag has space vesicular structure, and specific surface area is large, Bacillus thuringiensis and Provado and difenoconazole are had to absorption and slow releasing function, and the long action time to farm crop, is more easily absorbed by plants nutrient, fertilizer efficiency is more lasting, and boron magnesium slag also has adsorption to oxygen and moisture content, thereby there is water conservation effect.
4, technique is simple, in production process without hyperthermia drying, can effectively guarantee farm chemical ingredients, safety and environmental protection, is applicable to suitability for industrialized production.
