Problems solved by technology

[0002] Apple bagging commonly used in the market is generally a paper-coated film (inner black composite paper plus black plastic film) fruit bag, and the fruit bag published in the invention patent 02128086. The effects of freshness preservation, weight gain and chlorosis are good, but there are certain problems in its use, that is, apples are prone to sunburn after picking the bag and the storage period of apples after picking is short
[0003] The film-free bag is a substitute for plastic film bagging. It is mainly a high-concentration bagging type new high-fat film powder. The function of the film bag is relatively simple, and it has no antibacterial ability. It also needs to be properly sprayed with pesticides to ensure the good growth of fruits.
There has not been any report on the application of humic acid on film-free bags

Abstract

The invention discloses a humic acid bagging-free film bag and a preparing method and use method thereof. The preparing method includes: dissolving SiO2 in an acetic acid aqueous solution, adding chitosan, fully dissolving the chitosan, adding glycerinum, and acquiring a chitosan complex mother liquor; acquiring a potassium humate solution, and dissolving a certain amount of bottle gourd pakistan rubber in the potassium humate solution; mixing the chitosan complex mother liquor and the potassium humate solution with the bottle gourd pakistan rubber with stirring, evenly stirring the two solutions so as to acquire a novel high efficiency multifunctional humic acid bagging-free film bag mother solution which has an anti-freezing function, an antibacterial function, and an anti-pest function, and can provide nutriment matters, using water to dilute the mother solution, and directly spraying surfaces of fruits with the diluted mother solution to form films. The humic acid bagging-free film bag is non-toxic, is harmless, is easy to use, can avoid plastic pollution and complex operations due to the conventional bags, can allow the fruits to resist cold weather, bacteria, and pests, can provide desired nutriment matters for the fruits during a growth development process, and can effectively improve the quality of the fruits.
