Description

Biological seed coating agent

Technical field

The present invention relates to handle the preparation of crop seed, be specifically related to kind clothing agent.

Background technology

The fungi activator protein is a kind of bioprotein (patent No.: ZL01128666.0) that the Qiu Dewen doctor separates from fungi, it is that the protein that 42-60KD varies in size is formed by molecular weight, can induce and the resistance of activated plant damage by disease and insect, the coordinate plant growth metabolic system, promote plant growing, improve crop yield.Indoor pot and field trial through 40 various plants such as paddy rice, tobacco, citrus, capsicums show, control efficiency to damage by disease and insect is 40～80%, improve crop yield 10～20%, especially can effectively control virus disease, gray mold, bacterial wilt and aphid, two spotted spider mite etc.

It is relatively weaker that clothing agent market is planted by China at present, and product quality is poor, and kind is single relatively, and former medicine kind is few.Existing kind of clothing agent mostly is the suspension emulsion colloid, mostly is insecticide, bactericide or the mixture of the two, insecticide such as furans pellet, thimet, Imidacloprid etc., and bactericide mainly contains tmtd, carbendazim etc.Exist that dressing is insecure, the easy layering and precipitating of preparation, high malicious high residue and short a series of problems of active component lasting period.In recent years, the research about exciting the plant defense reaction to produce the albumen activator of disease-resistant and growth-promoting functions has caused extensive concern both domestic and external and attention, is one of focus of biopesticide research and development.Humus is the organic matter that extensively is present in weathered coal, peat and the brown coal, agricultural chemicals is had the effect of Synergistic slow release.Can be carrier with the fungi activator protein, add and to be rich in magnesium, sodium or amino acid whose humus and to formulate out the agent of a kind of new bio kind clothing through combination, whether complementary synergy of both optimum organization, thereby reach enhancing crop anti-adversity ability, disease-resistant worm and the short effect of increasing production of giving birth to, and solution has the high malicious high residue of kind of clothing agent now and a series of problems of active component lasting period weak point then are the problems of worth exploration in the pesticide research.

Summary of the invention

The object of the invention is exactly the deficiency at existing kind of clothing agent technology, with the biopesticide activator protein is active component, develop the new bio kind clothing agent of wide spectrum, efficient, low-residual, can not only realize seedling stage diseases and pests integrated control, shortly give birth to volume increase, and can improve crop quality.

The present invention seeks to realize like this: a kind of biological seed coating agent, comprise active component and the film forming matter of forming by silica gel, Sodium Benzoate, sodium alginate, ethylene glycol and soil temperature-80, active component is made up of activator protein and humus, wherein the percentage by weight of activator protein in biological seed coating agent is 0.3～0.8%, and humus is 3～5%.

Be described in further detail the present invention below.

Biological seed coating agent of the present invention is an active component with fungi activator protein and humus, adds film forming matter sodium alginate, ethylene glycol, silica gel, Sodium Benzoate and soil temperature-80, and acid scarlet, pH regulator agent and water.

The percentage by weight of above-mentioned each composition is:

Activator protein 0.3～0.8%

Humus 3～5%

Sodium alginate 2～8%

Ethylene glycol 2～5%

Silica gel 1～3%

Sodium Benzoate 0.1～0.2%

Soil temperature-80 2～4%

Acid scarlet 0.3～0.6%

PH regulator agent 0.5% is sodium dihydrogen phosphate 0.375% wherein, sodium hydrogen phosphate 0.125%

Water surplus

The former medicine manufacturing process of activator protein: by the patent No. is that disclosed method obtains protein concentrated solution among the ZL01128666.0, concentrate is got albumen dry powder after-70 ℃ of freeze-drying separate can make the proteinogen medicine, and the disease fungus of making the activator protein of biological seed coating agent is that the alternaria tenuis (A.tenuis Nees) of interlink spore genus (Alternaria) is sampled in the lettuce black spot.

Humus can be one or more mixing in sodium humate, potassium humate, humus magnesium and the fulvic acid (humate active ingredient HA 〉=65), keep total amount 3%～5%, when two or more mixes, only control total amount, each component relative quantity is any.

The biological seed coating agent preparation method:

By the prescription requirement, activator protein, humus, silica gel, Sodium Benzoate, sodium alginate, ethylene glycol, soil temperature-80, acid scarlet etc. are after fully mixing, putting into ultramicro-grinder fully grinds, supply excess water at last, add the pH regulator agent and regulate the biological seed coating agent that acid-base value can obtain being applicable to paddy rice, corn, wheat, soybean, cotton, capsicum.The high speed homogenize machine that uses in manufacturing process of of the present invention kind of clothing agent grinds, and can make the fineness of finished product reach 2～4 microns, has improved dispersion, the suspension of finished product greatly, thereby has guaranteed that the agent of kind clothing is not stratified during accumulating, do not precipitate.

The biological seed coating agent physicochemical character:

Acidity-basicity ph value 6.0-6.8

Film formation time 10-13min

The coating effect film forming is better, fastness good, non-cakedly do not become piece

Expulsion rate＜0.5%

The using method of biological seed coating agent:

Medicine slurry and crop seed fully stirred up to soup according to 1: 30～80 ratio be evenly distributed to the surface of the seed, can sow after drying.

Through a large amount of tests as can be known, the agent of new bio kind clothing all meets the general requirement of kind of clothing agent fully on physicochemical character, and film forming is better, the rapid film-forming of dressing energy under the nature situation, do not come off, do not link, do not become piece, evidence simultaneously can obviously promote the growth of paddy rice, corn, wheat, soybean, cotton, capsicum, improves germination rate and planting percent, and is remarkable to the extermination of disease and insect pest effect of various crops.
