A kind of humic acid-type fruit bag-free film agent and its application method

Abstract

The invention discloses a humic acid-type fruit bag-free film agent and a use method thereof. Sodium alginate is dissolved in water and stirred evenly, and then Tween‑20 and Span‑20 are added to form a sodium alginate solution; potassium humate is completely Dissolve in water and add glycerin to form potassium humate solution; fully stir sodium alginate solution and potassium humate solution to form agent A; dissolve calcium chloride in water to obtain agent B, spray agent A on the surface of the fruit first when using, and then spray Agent B: The humic acid-type fruit bag-free film not only has the characteristics of antibacterial and antibacterial, antifreeze, anti-pest, etc., but also shortens its film-forming time and has better film-forming properties; the shading performance is also obtained correspondingly The improvement can not only realize the characteristics of fine and smooth fruit surface, beautiful and bright color, prevention of diseases and insect pests, and reduce the use of pesticides that traditional bagging has, but also solve the problems caused by rainwater soaking and lax sealing caused by paper bagging. Rough surface, serious water rust, dull color and other problems.

Description

Technical field [0001] The present invention belongs to the field of agricultural applications, particularly, to a bagging film formers Free fruit humic acid type and methods of use. Background technique [0002] Our country had in the 1980's on the introduction of bagging technology, not only can prevent fruit bagging fruit produce phenomena such as dehydration, also avoid pests on fruit, fruit bagging once because of "security, good-looking" swept the entire market . But because of the short period of time, heavy task, strict operating requirements, labor issues such as lack of bagging technology, which has greatly restricted the economic cost growers. For bagging fruit, many utility patent is to reduce the cost by taking bagged bagging mechanical means, i.e., that such patent CN211580935U invention. But while it reduces labor costs bagging, but can not be solved due to the presence of paper plus film bagging fruit shading serious, uneven coloring, relying solely on fruit drop ...

AI Technical Summary

Problems solved by technology

However, although this reduces the labor cost of bagging, it cannot fundamentally solve the problems of serious fruit shading, uneven coloring, fruit relying solely on leaf nutrition, and fruit taste and quality decline due to paper and film bagging.

[0003] The bag-free film is sprayed to form a film evenly and quickly on the surface of the fruit. The applicant once proposed a bag-free film with antibacterial ability in the 2017 patent number CN107155739A. This film has the characteristics of antifreeze, antibacterial, and insect pest resistance, but there are problems such as relatively long film forming time and easy to be washed away by rainwater.
