Fully degradable bacteria stick water-retaining agent and preparation method thereof

Abstract

The invention provides a fully degradable bacteria stick water-retaining agent. The water-retaining agent is composed of, by mass, 1.2% of xanthan gum; 1% of polyvinyl alcohol; 0.6% of modified starch; 0.5% of carboxymethyl cellulose; 0.3% of trisodium phosphate, and the balance of distilled water. The bacteria stick water-retaining agent is non-toxic and pollution-free, and a 0.5 mm water-retaining layer is formed on the surface of a bacteria stick and the surface of mycelium by spraying the bacteria stick water-retaining agent to achieve a water-retaining effect. And in the growth process of mushroom heads and mushroom bodies, the inclusion of plastic fragments is avoided, so that the mushroom quality is better. The bacteria stick water-retaining agent is completely degraded by microorganisms and enzymes in nature, has no residue, and does not cause white pollution of soil. And the cost is low, and batch operation and production can be achieved easily.

Description

technical field [0001] The invention belongs to the field of functional water-retaining agents, and in particular relates to a fully degradable bacteria stick water-retaining agent. Background technique [0002] The water retention effect of the ultra-thin plastic water-retaining bag on the mushroom stick is very good, and at the same time, the mushroom tooth head can break through the bag and grow normally. The fungus stick water-retaining agent sprayed on the surface of the fungus stick also has the effect of water retention, making the mushroom emerge and grow more smoothly. [0003] But the ultra-thin plastic water storage bag also has some disadvantages: [0004] 1. The head of the mushroom needs to break through the bag. During the growth process of the mushroom, the stalk grows thicker and needs to continue to break the bag. During this process, the mushroom head and the stalk are mixed with plastic chips, which affects the quality of the mushroom. [0005] 2. Aft...

Problems solved by technology

[0004] 1. The head of the mushroom needs to break through the bag. During the growth process of the mushroom, the stalk grows thicker and needs to continue to break the bag. During this process, the mushroom head and the stalk are mixed with plastic chips, which affects the quality of the mushroom.

[0005] 2. After the mushroom growth cycle is over, the mushroom sticks will be smashed and buried in the soil, and the remaining part of the ultra-thin plastic bag will cause the "white pollution" of the land
