Abstract
The invention relates to a nano titanium rice planthopper control agent and a preparation method thereof. The nano titanium rice planthopper control agent comprises the following ingredients: 70 g of nano titanium microspheres with a shell-core structure, 100 g of silicone dioxide, 300 g of acetic acid, 300 g of honey, 80 g of monascus and 20 g of streptomyces microflavus. The action mechanism of the nano titanium rice planthopper control agent is as follows: burning rice planthopper larva and eggs to break the protective membranes and cell walls of the rice planthopper larva and eggs by using a photocatalytic reduction and oxidation function of nano titanium, and charging the alkaloid of the monascus and the streptomyces microflavus through the wounds to enter the cells of the larva or the eggs to break the cells. According to the nano titanium rice planthopper control agent and the preparation method thereof, the propagation of the rice planthopper is controlled by a physical method, harmfulness and toxic effects on human bodies are avoided, the resistance to drugs is not generated, and the nano titanium rice planthopper control agent is a safe, environment-friendly and non-toxic biological control agent.
Description
Technical field
The present invention relates to a kind of nano-titanium rice fulgorid control agent and preparation method thereof, belong to the technical field of plant pest management.
Background technology
Control rice fulgorid chemical pesticide is on the market a lot, but there is not yet photoactivation and physical anti-therapy is carried out to rice fulgorid, rice fulgorid to the harm of paddy rice except directly stinging suction juice, make growth retardation, time serious, rice clump is agglomerating withered, even cause outside the dead bar lodging in full field, lay eggs and also can stab plant, destroy the conducting tissue of paddy rice, hinder nutriment and transmitted virus, cause the paddy rice underproduction even to have no harvest, in the requirement of ecological organic plantation, prohibit the use any agricultural chemicals, be therefore necessary to provide a kind of physical prevention and controls to rice fulgorid harm.
Summary of the invention
For the demand that present ecological organic is planted; the object of this invention is to provide a kind of nano-titanium rice fulgorid control agent; it utilizes anatase structures; heat energy is produced under producing photocatalysis; carry out the cell wall burn to rice fulgorid larva and ovum; destroy the diaphragm of cell wall; and then allow the metabolite ergosterol of monascus; directly penetrate in its cell and destroy, flow out by cytoplasm from wound, carry out slaughtering effect; the photocatalysis of titanium; water body oxygen content is increased, improves the water quality of paddy field, and then promote the root system development of paddy rice.
For realizing above-mentioned object, the present invention is a kind of nano-titanium rice fulgorid control agent, and described rice fulgorid control agent comprises following raw material and makes, the nano-titanium microballoon 70g of core-shell structure, silica 1 00g, acetic acid 300g, honey 300g, fermented bacterium 100g; Wherein fermented bacterium comprises: monascus 80g, streptomyces microflavus 20g.
A kind of nano-titanium rice fulgorid control agent and preparation method thereof, comprises the following steps:
(1) get the raw materials ready according to the raw material of nano-titanium rice fulgorid control agent;
(2) after being mixed with acetic acid by honey, carry out stirring and be in harmonious proportion, throw in fermented bacterium, carry out 7 days aerobic fermentations, fermentation temperature is 28-30 DEG C, and every morning period, 6-7 point carried out clockwise stirring 0.5H, stirred 0.5H counterclockwise;
(3) after completing steps (2), by the nano-titanium microballoon of core-shell structure, silica sequentially adds in the raw material after fermentation, maintains the temperature at 55 DEG C, stirs 3H; Obtain nano-titanium rice fulgorid control agent.
Advantage of the present invention:
Compared with prior art, the present invention adopts physical combining with fermentation technology, change in the past to the stomach toxicity of the Pesticide use of rice fulgorid control, the prevention and controls of Nervous toxicity method, the soil vitality caused reduces, the problem that rice fulgorid develops immunity to drugs, by under the catalysis of nano-titanium and hydrogen reduction effect, to larva and the ovum of rice fulgorid, carry out the destruction of cell wall and diaphragm, ergosterol and other alkaloid are brought in its cell, carry out destroying its cell structure, reduce the hatching of rice fulgorid, its quantity is reduced from root, and reach the effect of control, and then water body oxygen content can be promoted, increase the gas permeability of soil, promote the prosperity of rice root, thus reach pest-resistant, resistant to lodging, improve the output of paddy rice, improve the quality of paddy rice, solve the problem of Rice Cropping non agricultural chemical residuum, reach the standard of environmental protection.
Accompanying drawing explanation
Fig. 1 is preparation method's process chart of a kind of nano-titanium rice fulgorid control agent of the present invention
embodiment
Composition of a kind of nano-titanium rice fulgorid control agent and preparation method thereof is described in detail below in conjunction with accompanying drawing 1
1, get the raw materials ready: raw material I 600g, raw material II are the nano-titanium microballoon 70g of core-shell structure, raw material III is silica 1 00g, fermented bacterium 100g; Its Raw I is that acetic acid 300g, honey 300g form, and fermented bacterium is monascus 80g, and streptomyces microflavus 20g forms;
2, after raw material I being carried out mix and blend, drop into fermented bacterium and carry out 7 days aerobic fermentations, fermentation temperature is 28-30 DEG C, and every morning period, 6-7 point carried out clockwise stirring 0.5H, stirred 0.5H counterclockwise;
3, after further step 2 being completed fermentation, drop into the nano-titanium microballoon of the core-shell structure of raw material II, carry out mix and blend 1H, period keeps temperature 55 DEG C;
4, add the silica of raw material II after step 3 being completed further, carry out mix and blend 2H, period keeps temperature 55 DEG C; The colloidal liquid obtained after having mixed is nano-titanium rice fulgorid control agent.
The nano-titanium microballoon of the anatase titanium dioxide of applying nano level of the present invention, carry out photocatalysis, destroy the worm's ovum of rice fulgorid and the diaphragm of larva and cell wall, and then Organic Alcohol is directly penetrated in its cellular tissure destroy its cytoplasm, and then play kill rice fulgorid larva in water body, avoid hatching adult, its stomach of the non-murder by poisoning of the present invention and nervous system, there is no the problem of poisoning and drug-fast problem, the oxygen content of water body and the gas permeability of soil can be increased, promote the well developed root system of plant, thus reach pest-resistant, resistant to lodging, improve the output of paddy rice, improve the quality of paddy rice, solve the problem of Rice Cropping non agricultural chemical residuum.
Although the present invention discloses as above with preferred embodiment; so itself and be not used to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when doing a little amendment and perfect, therefore protection scope of the present invention is when being as the criterion of defining with claims.
