Description
Technical field
The invention belongs to functional composite material and fruits and vegetables or crop bagging fields, and in particular to a kind of spraying film-forming type fruit
Vegetable or crop bagging composite material and preparation method and application.
Background technique
Current era, bag fruit and vegetables are increasingly welcome and like by masses, not only due to by protected by bagging
Fruits and vegetables crispy is sweet, and bagging facilitates fruits and vegetables and prevents disease pest from encroaching on, and pesticide application number is reduced, to reduce pesticide
Residual.But so well received fruit-vegetable covering bag use is extremely troublesome, needs artificial ladder or climb up fruit tree one by one to cover fruits and vegetables
Bag and tie up.By the huge restriction of use environment, manpower and cost, in addition, existing fruit-vegetable covering bag material generallys use nonwoven
Cloth, plastics, paper etc. are easy to be detained rainwater, dew, usually to cover in the environment that the fruits and vegetables pricked are in moist, easily grow
Plant germ, leads to diseases of garden stuff, and in order to avoid harmful microorganism breeding, some baggings are coated with or have impregnated long-acting in internal layer
Sustained-release pesticides undoubtedly increase fruits and vegetables pesticide seriously remaining risk.Therefore, the good fruit vegetable set of property easy to use, safe
Bag technique needs to develop.The utility model fruit-vegetable covering bag technology is aimed to solve the problem that since pest and disease damage takes place frequently and domestic labour is increasingly reduced
Social overall background under, bagging causes fruits and vegetables to have no harvest or quality decline not in time, the problem of economic benefit is badly damaged.
Spraying pesticide is the disease-resistant main means of insect prevention before fruit-vegetable covering bag or after bagging, due to pesticide dosage is big, point
Solution is slow, is easy to accumulate in crops, constitutes huge threat to human health.And due to the anti-medicine of pest, germ etc.
Property be continuously increased, apply the insect prevention disease resisting effect decline of conventional pesticide, high-toxic pesticide continued on, and causes vicious circle, ring
Border pollution is increasingly serious.With the continuous enhancing of health of people idea, demand of the people to green food is continuously increased, it is novel not
It is welcome deeply by society using the disease-resistant new tool of pesticide realization fruits and vegetables and crops insect prevention, new material.
Agricultural production practice shows to spray insect repellent agent or the plant extracts with antibacterial ability is to realize crops
The good method of the disease-resistant safety and environmental protection of insect prevention.
Allicin, matrine, camphor, citronella oil, limonoid, the leaf of chinaberry, fruit, core etc. are long-term existence in certainly
Right boundary, effective insect prevention antiviral agents and efficient anti-feedant have anthelmintic activity, bactericidal effect, coordinate plant growth etc. more
Kind function, and can be decomposed rapidly in the Nature, it is finally decomposed to carbon dioxide and water.And a variety of chemical substances in them
Synergistic effect, does not easily lead to pest and develops drug resistance with germ, can be used for a long time.Since they will not be direct to corresponding pest
Poisoning, but pest biotic population quantity is controlled, and the natural enemy that will not kill off the insect pests.They were answered agriculturally extensively in recent years
With having good control efficiency to pest and disease damage, be low toxicity, low-residual, environment-friendly type insect prevention antiviral agents.
The aldehyde materials such as antibacterial antiviral agents cinnamic acid similar to the above, vanillic aldehyde, anisaldehyde and salicylic acid, sorbic acid,
The organic acids such as caffeic acid are the natural materials with specific stimulation smell and special aroma generated in plant.Industrially
It is widely used as pest repellant, culicifuge, refrigerator deodorizer, antistaling agent etc.；There is sterilizing anti-corrosion in field of medicaments, resist and burst
Ulcer, antivirus action；It is usually used in flavorant in field of food industry, preservation and antisepsis is mould proof etc.；It can be also used for preparing fragrance
Essence prepares health care product etc..These substances are harmless, are readily biodegradable, and bacteria resistance function is significant, can also apply
It is antibacterial disease-resistant in crops.
Polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), polyethylene glycol (PEG), sodium alginate, chitosan, Guar
Glue, carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC)
Equal cellulose derivatives, starch derivatives, the lignin derivatives such as lignosulfonate, nitration of lignin, the macromolecules such as humic acid
Material is that nature is widely present or the artificial fully synthetic or semi-synthetic obtained product of warp, tasteless, odorless, nontoxic
Property, it has a wide range of applications.They have preferable biological safety, biodegradability etc., are widely used in agricultural, doctor
The numerous areas such as medicine, food, chemical industry, cosmetics, water process, METAL EXTRACTION and recycling, biochemistry and biomedical engineering.And it
Have the function of certain film forming, carry this medicine is mild controlled release, be good film forming and controlled release drug carrier materials.
The natural minerals such as diatomite, graphene, graphite, clay, mica, kaolin are existing for nature or to pass through
Process obtained widely used inorganic material.They are with porosity is big, absorbability is strong, sustained release performance is good, chemical property is steady
The features such as fixed, wear-resisting, heat-resisting, and energy toughening, enhancing, raising adhesive force, there is biggish pore volume, film can be made to shorten dry
The dry time.It is had a wide range of applications in fields such as medical sustained release field, feed, papermaking, chemical fillers.At present using papery, modeling
Expect to absorb existing for the solid types fruit-vegetable covering bags such as film, non-woven fabrics using cumbersome, pesticide residue, easily and is detained rain and dew water growth germ
The problems such as be need it is urgently to be resolved.
Summary of the invention
In order to overcome the disadvantages and deficiencies of the prior art, the primary purpose of the present invention is that providing a kind of spraying film-forming type fruit
Vegetable or crop bagging composite material.The material uses polyvinylpyrrolidone (PVP), sodium alginate, cellulose derivative, fruit
The film formings such as glue, resin substance carries medicine and reinforcing material as substrate, compound diatomite, graphene, kaolin etc., loads garlic
Element, the insect prevention such as matrine, salicylic acid, cinnamic acid antiviral agents and dyestuff obtain multiple color and have good insect prevention disease resistance
Can composite material, mixed system solution is sprayed air-dried on fruits and vegetables or crop surface after, at being adhered to fruits and vegetables or crop table
The film in face generates novel fruits and vegetables or crop adhesive type film bagging, does not influence fruits and vegetables or plant growth, and nontoxic secondary work
With, and can long-acting slow-release go out insect prevention disease-resistance substance.The technology simplifies traditional fruit-vegetable covering bag technology, by film type " sack "
It is sprayed on required fruits and vegetables by spraying mode, then condensation film forming, time saving and energy saving.The technology can form a film in crop surface
(being equivalent to crop surface bagging) plays the disease-resistant effect of insect prevention, reduces the use of pesticide to a certain extent, solve crop
Pesticide Residue.
Another object of the present invention is to provide the preparation sides of above-mentioned spraying film-forming type fruits and vegetables or crop bagging composite material
Method.
It is yet a further object of the present invention to provide the applications of above-mentioned spraying film-forming type fruits and vegetables or crop bagging composite material.
The purpose of the invention is achieved by the following technical solution:
