Effect, uses protective film as carrier, both ensure that nuisanceless.
The molecular formula of the chitosan is (C6H11NO4) N, molecular weight 161.2, active principle content is not less than 99%.
Chitosan provided by the present application uses marine organisms shrimp and crab shells extract, belongs to pure biological source -- chitin raw material.This product be with
Shrimp, crab shell are primary raw material.The macromolecule polysaccharide liquid-state mulch film extracted through biochemical technology.It is a using bioprocess technology
Biological product.Chitosan has good film forming, gas permeability, bio-compatibility.It forms film in skin surface, due to this
Film is space network, and various moisturizing factors, physiological function substance can embed wherein, and have Continuous slow release effect.Shell is poly-
The film forming mechanism of sugar has toughness by chitosan hydroxyl, chitosan solution, is easy to the characteristic to form a film.It is easy to using chitosan
The characteristic of film forming can be fabricated to have the water-retaining agent for cultivating plant or microorganism by the liquid-state mulch film that biology or enzyme are degraded.It should
Chitosan does not dissolve in general soda acid, and chemical property is highly stable, this is to restrict its major reason that cannot be developed for a long time.Through
Chitosan after deacetylation, white to flaxen powder, though it is also insoluble in water, aqueous slkali and organic solvent, it can
It is dissolved in dilute acid soln, including dilute mineral acid (hydrochloric acid, nitric acid etc.) and organic diluted acid (acetic acid, lactic acid, formic acid, ascorbic acid, fruit
Real acid etc.) in.Then be the dissolution when heating high temperature in the aqueous solution of the multivalence organic acid such as citric acid, tartaric acid, at a temperature of
It is then in gel after drop.Chitosan is wide to plant adaptability, and compatibility is good, without any toxicity and side effects, being capable of biology to person poultry harmless
Degradation, not hardened soil, can slowly be degraded to small molecule carbohydrate in the soil, nuisanceless to environment, be a kind of excellent
Pure natural ecological preparation.It can promote vegetable seeds advance germination.Well developed root system, root hair, fibrous root, secondary root quantity increase
Add.Root is plant sheet, and rhizosphere is flourishing, can enhance the suction fertilizer water absorbing capacity of plant, enhances drought resisting, lodging tolerance, and enhancing is exempted from
Epidemic disease power reaches the purpose of sturdy more results.Chitosan energy sufficiently activating rhizosphere state, dissolve nutrients molecule, quickly forms soil
Solution enables the nutrients such as nitrogen, phosphorus, potassium to obtain plant and substantially effectively absorbs.Make additive using chitosan, soil can be made beneficial
Bacterium such as actinomyces increase by 1000 times, harmful bacteria such as sickle-like bacteria and Nemata etc. substantially reduce, enhance soil supplying nutrient capability, from basic
Upper improvement soil eradicates hardened, raising soil organic matter content, convenient for continuous cropping.Chitosan can improve crop yield, improve crop
Quality, and so that it is restored natural flavor, resistance to storage, resistance to fortune, while reducing persticide residue (below international standard), it can be by green
Chrominance channel outlet.
The embodiment of the present application can also provide a kind of system using the chitosan biological liquid foliar nutrition protective film
The chitosan biological liquid foliar nutrition protective film that Preparation Method is prepared.
When in use, suitable foliar nutrition protective film is sprayed on blade face to be protected for the foliar nutrition protective film, from
So air-dry.It is infected with film protection fruit face isolation germ, due to being by spraying, plant protection film is very thin, blade face can be made normally to exhale
It inhales.The foliar nutrition protective film, as film forming main body, is cooperated the substances such as gelatin or glycerol, made using natural free of contamination chitosan
It is obtained with good film forming, the protective film of formation can be used as the carrier of nutrient, Fungicidal substance and insect killing substance
It uses, can uniformly be wrapped in blade exterior and form protective film, effectively improve the disease-resistant performance on blade face, prevent blade face by insect etc.
Invasion.The protective film can be with natural degradation, and the substance after degradation can be used as fertilizer by Foliage Absorption.
