Description
Technical field
The invention belongs to agriculture applied technology field, and in particular to a kind of humic acid is exempted from film cover bag and preparation method thereof and made
Use method.
Background technology
The Apple Bags generally used in the market are generally paper and membrane (interior black extrusion coating paper blackens plastic foil) fruit bag, hair
The fruit bag that bright patent 02128086.X is announced is as such, and paper and membrane fruit bag is imitated in terms of water conservation, fresh-keeping, weightening and chlorisis
Fruit preferably, but in its use there is also it is certain the problem of, i.e., apple is stored easily occurring to burn day and pluck apple after fruit after plucking bag
Phase is short.
Exempt from the substitute that film cover bag is plastic foil bagging, mainly highly enriched set pouch-type new high fat film pulvis sprays when using
Apply fruit face and quickly form a floor height molecule ultra-thin flexible film, although effect is significantly, the existing feature for exempting from film cover bag compares
It is single, without bacteriostasis, in addition it is also necessary to suitably spray insecticide to ensure the good growth of fruit.Humic acid is applied and is exempting from mantle
There is not yet any report on bag.
The content of the invention
In order to overcome the defect that above-mentioned prior art is present, film cover bag is exempted from it is an object of the invention to provide a kind of humic acid
And preparation method thereof and application method, this method is simple to operate, low for equipment requirements, environment-friendly;Through exempting from made from this method
Film cover bag can effective bacteria growing inhibiting, extend the Storage period of fruit, with good water conservation, fresh-keeping effect.
The present invention is to be achieved through the following technical solutions:
A kind of humic acid exempts from the preparation method of film cover bag, comprises the following steps:
1) by Nano-meter SiO_22It is dissolved in acetic acid aqueous solution, is stirring evenly and then adding into chitosan, fully adds glycerine after dissolving,
Stir, chitosan is made and is combined mother liquor;
2) take humic acid to be dissolved in potassium hydroxide solution, potassium humate solution is made, trigonella bean gum is then added, fully
Stir;
3) chitosan under agitation, is combined mother liquor and step 2) potassium humate of obtained addition trigonella bean gum is molten
Liquid is stirred, and adds glycerine, is sufficiently stirred for until it is dispersed into homogeneous system, it is female that obtained humic acid exempts from film cover bag
Liquid, is sprayed on fruit surface and obtains humic acid and exempt from film cover bag when using.
The chitosan is the chitosan that degree of acetylation is 70%~90%.
The mass concentration of acetic acid aqueous solution is 0.2%~0.6%.
Step 1) in, chitosan:Nano-meter SiO_22:Glycerine:Mass ratio=15 of water:(0.2-1.4):(0.4-1.6):30.
Step 2) in, the humic acid is fulvic acid, ulmic acid or humic acid.
Step 2) in, trigonella bean gum:The mass ratio of humic acid=(0.8-2):10.
Step 3) in add glycerine and humic acid mass ratio be (0.5-2):10.
The invention also discloses exempt from film cover bag using humic acid made from the above method.
The invention also discloses the application method that above-mentioned humic acid exempts from film cover bag, by humic acid exempt from film cover bag mother liquor add water it is dilute
100~1000 times are released, in fruit young fruit period, sprays the 1st time, was sprayed 1 time every 10-20 days later, in fruit after spraying 2-3 times
Surface forms one layer of complete diaphragm;Wherein, the time of sprinkling film forming is 0.5-2h every time.
Compared with prior art, the present invention has following beneficial technique effect:
Humic acid disclosed by the invention exempts from the preparation method of film cover bag, using humic acid, chitosan and glycerine as primary raw material,
Humic acid has the functions such as good physiologically active and absorption, complexing, exchange, it is possible to increase the effect of plant resistance, simultaneously
Due to the effect of its complexing (chelating) metal ion, the moderate-element and trace element needed for plant are easily carried to plant
In vivo, utilization rate of the fruit to various nutrients is improved, the essential element of humic acid has carbon, hydrogen, oxygen, nitrogen, sulphur and phosphorus, can be to fruit
The real nutritional ingredient provided required for growth.Preparation method is simple to operate, low for equipment requirements, environmental protection, is adapted to industrialization
Amplification production.
The obtained of the present invention exempts from film cover bag, with bacteriostasis antibiosis ability, while the growth of fruit normal health is ensured,
The use of agricultural chemicals can effectively be reduced.Humic acid using the present invention exempts from film cover bag, can protect fruit and blade, effective pre- anti-bacteria
The influence of infection and insect pest to apple development, optimizes fruit development level, while not influenceing illumination and coloring, can make fruit face
It is bright and clean, it is bright in colour.Cleaned before fruit is edible with water, film forming can automatically disengage fruit body.
Bagging is carried out to fruit using the method for the present invention, the entrance of air and bacterium can be effectively prevented, delay fruit
Real corruption, extends the Storage period of fruit, with good water conservation, fresh-keeping effect.
