Description

Green tea plantation disinfectant use in agriculture

technical fieldthe present invention relates to a kind of green tea plantation disinfectant use in agriculture, its main component is sea grass polysaccharide, polyhexamethylene guanide, chitin, glycine hydrochloride are mixed into mixture in proportion.The diseases prevention antibiotic and sterilizing of green tea and other jasmine tea crops can be widely used in.The kind of the diseases prevention antibiotic and sterilizing product of existing tea grower crop is a lot, common are bleaching powder, calcium hypochlorite, sodium dichloro cyanurate, sym-closene, chlorine dioxide, potassium permanganate, hydrogen peroxide, Peracetic acid, acetic acid, copper sulphate etc.Antibiotic and sterilizing performance differs, and has dividing of high, medium and low effect.The active ingredient of high effect disinfectants and content are directly proportional to price often; And, corrosivity, penetrating odor toxic to crops, have medicament residue; There is pollution to environment, having certain damage to being sterilized article.Therefore, agricultural avocation wish to have that a kind of antibacterial disinfection efficiency is high always, has a broad antifungal spectrum, to people and poultry safety and stability, drug residue free, environmentally safe, to crop without the green tea plantation disinfectant use in agriculture damaged.

background technologyalong with the development with clothing product industrial upgrading that deepens constantly of agricultural restructuring, crop mix there occurs essence change, and new sick worm constantly occurs, it is caused harm and increases the weight of gradually.Situation still based on chemical control on diseases and pests controlling will continue, and the use of agricultural chemicals will be more extensive.Along with our people's growth in the living standard, more strict to the requirement of agricultural product quality and safety, the thus sick worm of scientific and reasonable use pesticide control, the task of protecting agriculture good harvest and raising agricultural product quality is more arduous.This just needs an agricultural technology spread troop having technology, understand specialty.Particularly important in modern tea production.Therefore, the means such as integrated use agricultural, biology, physics, chemistry, causing harm of prevention and corntrol agricultural pest, reduce usage amount and the service efficiency of chemical pesticide to greatest extent.Current tea grower assembles agricultural chemicals sales department, major part agricultural chemicals operator does not possess plant protection knowledge, to agricultural chemicals and Pesticide use and relevant law thereof, regulation know less, the tea place techniques of pest control are also quite short of, and can not recommend suitable medicament kind and the using method of science to tea grower.Tea grower runs into tea place and disease worm occurs when needing to purchase medicine, the relevant regulations that operator exists not in accordance with Pesticide use recommends agricultural chemicals, have even after tea grower describes damage symptom, they without analyse, some current most disease and pest control agricultural chemicals use simultaneously, a few class agricultural chemicals of insecticide, miticide, bactericide is arranged in pairs or groups to peasant, although tea grower is pretty good with rear sensory effect, sick worm controls, and pesticide dosage increases greatly, except increase cost, also cause the severe contamination of environment and agricultural product.Pesticide market exists sells personation, agricultural chemicals of poor quality and unlicensed business activity phenomenon, in recent years the relevant departments such as agricultural sector of county and industrial and commercial bureau combine to the means of agricultural productions such as agricultural chemicals sell examine greatly big-eared, find much expired, inferior, even national banned pesticides floods market, there is unlicensed business activity phenomenon, the heavy damage ecological balance, causes the ferocious again of pest to stick up.Because basic unit professional technique strength lacks or weak, there is quite a few tea grower to can not get the accurate instruction of pest control techniques, non-Symptomatic medicine, see worm or regularly spray medicine phenomenon is general, make the agricultural chemicals rate that hits extremely low, diseases and pests controlling weak effect.Also too rely on a certain chemical pesticide simultaneously.Most tea grower once used the control efficiency of certain agricultural chemicals to a certain sick worm good, with regard to this kind of agricultural chemicals of Long-Time Service, even sick worm develops immunity to drugs, also kind is not changed, but continue to increase dosage, result is while cost constantly rises, and also increases the residual quantity in agricultural product, serious environment pollution.Tea grower's application method is improper.According to the survey, some tea growers, when the extermination of disease and insect pest, only follow the line of least resistance, do not say drug safety and control efficiency, when typical case uses sprayer to spray medicine exactly, uneven without shower nozzle and sprinkler cap, sheet incompleteness, direct thumb pinches and just sprays medicine, and the liquid of ejection is not vaporific, switch place water clock.This insecticide-applying way, the liquid being sprayed on the sick worm of target is few, and the agricultural chemicals descended slowly and lightly in the environment is a lot, and except preventive effect is extremely low, spray medicine person safety can not ensure, and also causes severe contamination to environment.Indivedual tea grower early goes public for making agricultural product, sells high price, pursues economic interests, does not take popular health into account, and not by good agricultural regulation, in safety interval of pesticide pollution, gather in the crops agricultural product, poisoning happens occasionally.In addition, pesticides packaging thing process problem is serious.Tea grower, after use agricultural chemicals, abandons the packing material such as bottle, sack at limes marginis, the edge of a field conveniently, can not neglect an a conduit made of long bamboo to environment and the ecological pollution caused.According to " agricultural chemicals management rules " regulation, pesticide market is cleared up, get carefully illegal operation.Strengthen qualification certification and the new technology training of agricultural chemicals operator, improve operator's level professional technology, instruct the Peasants in Scientific rational use of medicines; Strengthen pesticide quality inspection Check, punish severely illegal operation, stop personation, agricultural chemicals of poor quality listing, purification pesticide market.It was the safe handling ensureing agricultural chemicals that I 21 strengthens Pesticide use supervision, and the Ministry of Agriculture has formulated " major experiment specification general provisions " pesticide industry standard in 2007.Therefore, reply safe handling agricultural chemicals extensively publicizes, make that tea grower is conscious carries out science, reasonable employment according to major experiment technology, strict implement safety interval of pesticide pollution, reduce residue of pesticide, market is found to the product of residue of pesticide, should destroy in time, forbid in Tea Production, use high poison, persistent pesticide.Tea grower is the implementer of tea production, also be the direct user of agricultural chemicals, causing harm of the pests such as effective disease and pest control, should be accomplished, the quality of accomplishing the safe handling of agricultural chemicals again, reducing environmental pollution, improving agricultural product, this just must improve the scientific and cultural quality of numerous tea growers, strengthen environmental protection, ecology, awareness of safety, technically make an effort in the PCO technology such as sick worm and major experiment, by publicity, training, make numerous tea growers grasp diseases and pests controlling and agricultural chemicals relevant knowledge, form the atmosphere using agricultural chemicals consciously, scientifically and rationally.In production, guide the reasonable rotation of tea grower to use agricultural chemicals, avoid long-term, single, use same (class) agricultural chemicals in a large number, delay the generation of pesticide resistance or cross resistance.Widely popularize applying biological agricultural chemicals, as bacillus thuringiensis,Bt, matrine etc.Cause the negative effect to environment, ecology and agricultural product quality for Pesticide use, implementing integrated pest management engineering is the effective way ensureing major experiment.Emphasis adopts five large measures; One is plant quarantine, and the strict propagation, 5 controlling quarantine harmful organisms is prolonged, and effectively intercepts the source of harmfulness Pest organism; Two is implement cultural control, reduces the pest generation radixes such as disease worm; Three is Devoting Major Efforts To Developing biotechnologys: four is improve to observe and predict means, improves and observes and predicts accuracy, promptly and accurately carry out the pesticide control of disease worm, and five is widely popularize the anti-worm of curing the disease of biopesticide, forbids the use of high poison, persistent pesticide.The object of the present invention is to provide a kind of green tea plantation disinfectant use in agriculture that can overcome existing procucts deficiency, have that antibacterial disinfection efficiency is high, has a broad antifungal spectrum, to people and poultry safety and stability, drug residue free, environmentally safe, without the green tea of the features such as damages, disinfectant use in agriculture planted to crop.

summary of the inventionmain points of the present invention are to select suitable component, and carry out rational mixture, and through heating, dissolving, mix, the technique such as cooling forms green tea and plant disinfectant use in agriculture.

The formula that the present invention selects following (component and percentage by weight % thereof): sea grass polysaccharide 10.0-15.0; Polyhexamethylene guanide 0.3-0.5; Chitin 15.0-20.0; Glycine hydrochloride 0.2-0.3; Purified water adds to 100.

Each dosage TC, TG, LDL-C level of sea grass polysaccharide sea grass polysaccharide is all lower than hyperlipidemia model group, and its HDL-C level is then all higher than hyperlipidemia model group.Sea grass polysaccharide can reduce the LDL being considered to activate arteries and veins hardening factor, raise the level being considered to the HDL of the anti arteriosclerosis factor, sea grass polysaccharide can reduce the AI of experimental rat while reducing blood fat, illustrates that sea grass polysaccharide can play certain prevention effect to coronary heart disease.The possible cause of sea grass polysaccharide effect for reducing blood fat is: on the one hand, and polysaccharide can accelerate liver and gall circulation, promotes that ketoboidies utilizes, and then promotes lipolysis; On the other hand, water-soluble dietary fiber is belonged to from polysaccharide viewed from physical property.Research shows, water-soluble dietary fiber has good effect for reducing blood fat.Long term high-fat diet can cause the fatty liver of experimental rat, and sea grass polysaccharide has antagonism to the fatty liver caused by high fat diet, and presents certain dose-effect relationship.Therefore, sea grass polysaccharide can reduce hepatocellular steatosis, keeps the normal of liver cell form, has certain prevention effect to fatty liver.Its possible cause is the lipid peroxidation injury that polysaccharide inhibits rat liver cell membrane and endomembrane system, decreases the macromolecular substances forming cell and each kinds of oxidation reaction occurs, thus prevent the generation of fatty liver.Sea grass polysaccharide is also by the activities of antioxidant enzymes such as enhancement of SOD, GSH-Px, promote the enzymatic reaction of defence lipid peroxidation, reduce interior free yl level, and then MDA content in reduction body, thus improve hyperlipemia rat vivo oxidation-anti-oxidant imbalance state, reduce because the excessive free radicals of hyperlipemia generation is to the damaging action of body.

Chitin is present in the rudimentary plant mushroom of occurring in nature, the cell of algae, the shell of crustacean shrimp, crab, insect, the cell wall etc. of higher plant is from crab, shrimp shell, apply the animality high molecular cellulose that genetic engineering extracts, by scientific circles praise for " the 6th vital principle "! Therefore functional immune substance is regarded as by American-European Zhong government.Also containing trace " chitosan " in the plant such as glossy ganoderma, Cordyceps sinensis, but content is only between 2%-7%.Chitin is the positive food fiber of unique positively charged in universe, and in the natural organic-compound that the earth exists, what quantity was maximum is cellulose, is secondly chitin, estimates the annual biosynthetic chitin of natural world 10,000,000,000 tons nearly.Chitin is the organic compounds containing nitrogen that on the earth, quantity is maximum, and next is only protein only this 2 point, is just enough to the importance that chitin is described.Chitin can directly act on immune organ candidate stem cell in human body, fully can penetrate into all cells and by cytoactive, immunocyte quantity in atomization be increased, Quality advance, improve natural curability greatly, fundamentally improve function of immune system.The field trial research of chitin coated slow releasing fertilizer shows: the stable growth that can promote crop plant compared with instant nitrogenousfertilizer better, realizes the volume increase of crop.And, CCF overcomes the shortcoming of fugitive, the violent effect of common chemical fertilizer, one time base is executed, the nitrogen nutrition needs that can meet whole breeding time eliminate the Land Consolidation Project sustainable development evaluation index system of the index composition topdressed, Hierarchy Analysis Method is adopted to determine each evaluation criterion weight, calculate Land Consolidation Project and evaluate comprehensive scores, thus provide quantizating index for the selection of county land Consolidation Project.The field trial research of chitin coated slow releasing fertilizer shows: CCF can promote the stable growth of crop plant better compared with instant nitrogenousfertilizer, realizes the volume increase of crop.And, CCF overcomes the shortcoming of fugitive, the violent effect of common chemical fertilizer, one time base is executed, the nitrogen nutrition needs of whole breeding time can be met, eliminate the difficulty of topdressing and loaded down with trivial details, while saving of labor, blindness artificial when also can avoid topdressing increases fertilizer amount, and causes the problems such as fertilizer waste, the soil salinization.The aftereffect of remaining nutrient to next crop obvious in season, thus improve utilization rate of fertilizer, for the crops obtaining high-yield high-quality lay the foundation.By tomato

-cucumber test is known, and the nitrogen utilization efficiency of CCF can reach 58%, and residual effect is obvious, has has substantially met or exceeded domestic like product level.

During glycine hydrochloride is, low effect disinfectants, as often kind of single disinfection method sterile components of compound.In this component any one folk prescription time all can not kill mycelia and the spore of bacterial spore and germ, after being mixed into compound in proportion, but can being killed mycelia and the spore of bacterial spore and germ by its synergistic characteristic, substantially increase sterilization effect.Containing Multiple components in compound disinfectant, the content ratio of each single component reduces relatively, therefore also few to the side effect such as toxicity, excitant of people, animal, crops.
