Description
Technical field
The invention belongs to medicament-fertilizer mixture field, particularly a kind of MTI-446 slowly-releasing medicament-fertilizer mixture and production method thereof.
Background technology
Paddy rice is one of most important cereal crops of China, exceedes in the world half population using paddy rice as staple food. Insect pestThe output of serious threat paddy rice, is about 10% because insect pest causes the loss of rice yield every year. Since the nineties in 20th century, ChinaRice borer disaster reaches highest level, and wherein striped rice borer disaster is particularly serious; Rice water weevil, planthopper, rice leaf roller, grub andThe insects such as wireworm are serious threat rice yield also. At present, the control of rice grub is taking chemical prevention as main, traditional chemical desinsectionA large amount of uses of agent, have not only increased production cost, and easily make insect develop immunity to drugs, and cause environmental pollution, threaten peopleClass health. Use or abuse chemical insecticide due to a large amount of, cause insect to decline to medicine and sensitiveness, conventional pesticides can notEffectively control rice insect pest.
MTI-446 is that one acts on acetylcholinergic receptor, and the Novel tobacco bases that can block the normal neurotransmission of insect killsWorm agent. Have tag, stomach toxicity, quick-acting height, lasting period reach 3-4 week, insecticidal spectrum is wide, absorption is strong in root, have and can be doneThe feature that the root of thing and leaves and stems absorb rapidly, and sucking insect is had to excellent preventive effect.
Medicine fertilizer is that agricultural chemicals and fertilizer are mixed, and by processing, fertilizer and agricultural chemicals are stable in specific compound system andThe mixture forming, has and kills the function that presses down diseases and pests of agronomic crop and plant growth adjusting, and can provide nutrition for crops, hasIn time, also has to crops and nutrient is provided, improves the function of fertilizer efficiency and agricultural chemicals utilization rate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of MTI-446 slowly-releasing medicament-fertilizer mixture and preparation method thereof, this medicine fertilizerMixture has the double action of agricultural chemicals and fertilizer, both can prevent and treat rice grub and improve plant vitality and pest-resistant harmful ability, againCan improve soil, regulate the content of Nitrogen In Soils, phosphorus, potassium, increase crops quality, active ingredient slowly discharges, lasting medicine,The utilization rate that improves medicament-fertilizer mixture, saves labour turnover.
Technical solution of the present invention is:
A kind of MTI-446 slowly-releasing medicament-fertilizer mixture, is made up of following active ingredient by mass fraction:
MTI-446 0.01%～94.9%;
Fertilizer 5%～99%;
Sustained release agent 0.1%～10%;
Described sustained release agent is Lauxite, polyacrylamide, polyvinyl alcohol, hydroscopic high-molecular resin, poly butylene succinateIn at least one.
Described amine slowly-releasing medicament-fertilizer mixture, is made up of following active ingredient by mass fraction:
MTI-446 1%～20%;
Fertilizer 72%～89%;
Sustained release agent 8%～10%;
Described sustained release agent is Lauxite, polyacrylamide, polyvinyl alcohol, hydroscopic high-molecular resin, poly butylene succinateIn at least one.
Described fertilizer is urea, phosphate fertilizer and potash fertilizer, and wherein, the mass ratio of urea, phosphate fertilizer and potash fertilizer is 2:1:1.
Described sustained release agent is polyacrylamide, polyvinyl alcohol and hydroscopic high-molecular resin (being called for short SAP), wherein, and poly-thirdThe mass ratio of alkene acid amides, polyvinyl alcohol and hydroscopic high-molecular resin is 1:1:1.
A production method for MTI-446 slowly-releasing medicament-fertilizer mixture, granule preparation process is as follows:
Fertilizer is mixed, add the former medicine of MTI-446 to stir, obtain agrochemical fertilizer mixture, when stirring, control agricultural chemicalsFertiliser mixtures moisture content is 7%～10%, adds sustained release agent, enters comminutor extruder grain, obtain particle diameter 2mm～3mmGrain, dries, and cooling, metering packing, obtains MTI-446 slow releasing medicinal fertilizer granular formulation.
A production method for MTI-446 slowly-releasing medicament-fertilizer mixture, water-soluble mixture preparation process is as follows:
Fertilizer and the former medicine of MTI-446 are mixed, stir, add water-soluble slow-releasing agent and stir, control moisture content and exist7%～10%, enter comminutor extruder grain, obtain the particle of particle diameter 2mm～3mm, dry, cooling, metering packing, makes furan wormAmine water-soluble pesticide-fertilizer.
A production method for MTI-446 slowly-releasing medicament-fertilizer mixture, rushes application medical fertilizer preparation process as follows: by fertilizer, MTI-446Mix with sustained release agent, dry packing, make MTI-446 and rush application medical fertilizer.
A production method for MTI-446 slowly-releasing medicament-fertilizer mixture, granule preparation process is as follows:
