Abstract
The invention relates to a kongpo monkshood root plant based nano carrier water suspending agent and a preparation method thereof. The invention is characterized in that the suspending agent is prepared from the following raw materials in parts by weight: 45-55 parts of kongpo monkshood root and the like. The suspending agent provided by the invention can be used for soil treatment after planting before seedling, and has the characteristics of farmland weed eradication and broad-spectrum sterilization. Compared with the prior art, the formulation provided by the invention has the characteristics of favorable weed eradication effect, high safety for environment and the like, and the weed can not easily generate drug resistance, thereby having wide application prospects.
Description
Technical field
The invention belongs to the nuisanceless fertilizer technical field, be specifically related to a kind of kongpo monkshood root plant pesticide composition.
Background technology
Plant can run into various damage by disease and insect in the occurring in nature process of growth, fungus disease particularly, its kind is many, and disease is serious, and, dark fund sick etc. sick such as sick, the red gold of gold is that the disease of control occurs generally, comparatively to be difficult on many crops, bring huge loss to agricultural production, mainly occur in the parts such as tender seedling, bud, the tip of crop, when serious, blade is withered, curling, the browning look, withered.A large amount of chemical means that use are prevented and treated at present, yet domesticly for the medicament of preventing and treating powdery mildew, mainly contain the unicity of for many years medication of methyl and the particularity of chemicals, be easy in use operating personnel and ecotope be made to serious harm, and have in a large number residual, easy-clear, do not cause injury to edible people, and therefore country is own through banning use of highly toxic pesticide, greatly develop the green non-pollution vegetables, so be badly in need of developing the public nuisance-free agricultural chemicals that low toxicity is even nontoxic.Causing harm of farmland weed often causes a large amount of underproduction of crops every year.Use chemical herbicide to remain the Main Means of current weed control, but, due to a large amount of and unreasonable use chemical herbicide, caused the problems such as environmental pollution, residue of pesticide and herbicide resistance, be subject to extensive concern.Therefore, exploitation is efficient, the new herbicides of low toxicity, low-residual, becomes problem in the urgent need to address.Find bioactivator from plant, and then the environmentally friendly agricultural chemicals of development of new, be the hot fields of the outer research of Present Domestic.
China is large agricultural country, and about 400,000,000 m2 of area occur the crop diseases and pest crop smothering throughout the year, and annual the need produced and used 800,000 tons, agricultural chemicals, and agricultural chemicals has become indispensable factor in agricultural production.Being widely used of agricultural chemicals, although production development has been played to important function, also occurred pesticide resistance problem such as insect pest, disease, to the pollution of environment and in agricultural and animal products residual and accumulation problem, injure natural enemy, destroy balance of nature, cause pest resurgence problem etc.This development to novel pesticide has proposed higher requirement.Especially, since entering 21 century, along with the cry of people's uphold nature, protection of the environment, concern food security is day by day surging, harmless boilogical agricultural chemicals industry and biological control area research have obtained rare opportunity to develop.
Biotic intrusion is considered to cause the one of the main reasons of the interior ecosystem degradation of world wide and the loss of biodiversity.Instruction plant is by replacing native plants and then setting up the integrality that single species group threatens the ecosystem.Invasion mechanism and the impact of determining exotic plant are most important to predicting its spreading rate, formulation prevention and control and even ecological reconstruction (ecologicalrestoration) measure.At present, for the reasonable utilization of adventive instruction plant, report is also arranged, the Activities of Some Plants extract all possesses desinsection, antibiotic characteristic.But not yet form the commercialization pesticidal preparations, market in urgent need is a kind of is conducive to environmental protection, effectively sterilization, weeding, and can be applicable to the large nuisanceless bactericidal and herbicidal medicament of plant of producing.Will be at invasion habitat choose reasonable plantation substituted plant source pesticide by this research, thus realize its continuous and effective is controlled and technical support.
Summary of the invention
The invention provides a kind of kongpo monkshood root plant resource nano controlled-release suspending agent, it is characterized in that, it comprises that the raw material of following parts by weight prepares: kongpo monkshood root 45-55 part, yellow top chrysanthemum 10-20 part, fragrant eupatorium herb 10-20 part, water 10-20 part, nano controlled-release carrier 20-25 part;
The preparation method of described nano controlled-release carrier is:
(1) silicon hydroxyapatite, concave convex rod are mixed according to the mass fraction proportioning of 35-45:10-15, join in the mixed solution of 230 parts of methyl-sulfoxides (DMSO) and 50 parts of methyl alcohol, in 65 ℃, stir 60 hours, filter, and wash and remove excessive methyl-sulfoxide (DMSO) for 3 times with the hot ethanol of 60 ℃ of temperature, put into vacuum drying chamber, dry 24 hours of 60 ℃ of temperature, grinding is sieved, and obtains modified composite one time;
(2) 1 part of modified composite, 15 parts of potassium acetates and 25 parts of distilled water are mixed, in temperature 50 C, stir more than 10 hours, in 30 ℃ of temperature, first under ultrasonic electric power 350W condition, disperse 3.5 hours, and then disperse 4 hours under ultrasonic electric power 250W condition.Filter, and wash 3 times with distillation, 80 ℃ of vacuum drying 24 hours, grinding is sieved, and obtains twice-modified compound; (3) above-mentioned 1 part of twice-modified compound is disperseed to 60min at the 600W power ultrasonic, with constant temperature heating device, be heated to 90 ℃, and stir (1200r/min) 60 minutes with mechanical agitator; Obtain the nano controlled-release carrier complexes.
