Humic acid type fruit bagging-free film agent and use method thereof

Abstract

The invention discloses a humic acid type fruit bagging-free film agent and a use method thereof. The method comprises the following steps of dissolving sodium alginate in water, uniformly stirring, and adding tween-20 and span-20 to form a sodium alginate solution, completely dissolving potassium humate in water, and adding glycerol to form a potassium humate solution, fully stirring the sodium alginate solution and the potassium humate solution to form an agent A, and dissolving calcium chloride in water to obtain an agent B, firstly spraying the agent A on the surfaces of the fruits, and then spraying the agent B. The humic acid type fruit bagging-free film has the characteristics of bacteria resistance, bacteriostasis, freezing resistance, insect pest resistance and the like, the film forming time is shortened, and the humic acid type fruit bagging-free film also has better film forming property; the shading performance is correspondingly improved, the characteristics of fine and smooth fruit surfaces, beautiful and gorgeous color and luster, prevention of plant diseases and insect pests, reduction of pesticide use and the like of traditional bags can be realized, and the problems of rough fruit surfaces, serious water rust, dim color and luster and the like caused by rainwater soaking, untight sealing and the like due to paper bags and the like can be solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural application, and in particular relates to a humic acid-type fruit bag-free film agent and a use method thereof. Background technique [0002] Our country introduced bagging technology in the 1980s. Fruit bagging can not only prevent fruit from dehydration and other phenomena, but also prevent pests from invading fruit. Bagging fruit once swept the entire market because of its "safety and good-looking" . However, the bagging technology has problems such as short time period, heavy tasks, strict operation requirements, and poor labor force, which greatly restrict the economic cost of fruit farmers. For the bagging technology of fruits, many utility model patents are to reduce the cost of manual bagging by adopting the method of mechanical device bagging at present, and the invention patent CN211580935U is exactly this kind. However, although this reduces the labor cost of bagging, it cannot f...

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.
