Problems solved by technology

At present, most of the earthworm boxes on the market are plastic earthworm boxes, which are non-degradable materials. After people fish, the bait and storage boxes will be discarded, and throwing them in the soil or water will cause a burden and harm to the environment.

Embodiment

[0033] A preparation method of corn husk degradable earthworm box, comprising the following steps:

[0034] Step S1, pruning and cleaning

[0035] Cut off the part of the corn husk whose thickness is less than 0.15mm to obtain corn husks with a length of 80-150mm, the thickness of the base of the corn husks is 0.45-1.55mm, and then carry out surface cleaning treatment on the corn husks to remove impurities on the inner and outer surfaces;

[0036] Step S2, softening and flattening treatment

[0037] After step S1 is completed, the corn husks are subjected to hydrothermal softening treatment in a constant temperature water bath at 50-70°C for 1-3 hours, and then stress grooves are opened on the inner surface of the corn husks along the fiber direction, so that the corn husks become unfolded flakes material, the adjacent spacing of the stress grooves is 10-20mm, the width is 0.1mm, and the thickness is 1 / 4-1 / 3 of the corn husk thickness;

[0038] Step S3, weak alkali treatment...

Abstract

The invention discloses a preparation method for a degradable earthworm box made of corn bran. The method comprises five steps of pruning and cleaning, softening and flattening, weak alkali treatment,sizing and shaping, and softening and box preparing. The invention also discloses a degradable earthworm box made of corn bran which is prepared by the above preparation method. The preparation method is simple, the prepared degradable earthworm box made of corn bran has excellent mechanical performance and good environmental protection performance, and reuse of waste is realized.

Description

technical field [0001] The invention specifically relates to a corn husk degradable earthworm box and a preparation method thereof. Background technique [0002] Corn stalks are one of the main categories of crop waste today. They are burned or buried nearby, which not only pollutes the environment but also wastes renewable resources. However, there are few studies on the utilization of corn husks. As a part of corn stalk, the husk will have great ecological significance if it is fully utilized. On the one hand, as a natural degradable and renewable resource, corn husk has the characteristics of long fiber, strong tensile force, flexibility and whiteness. It is a good crude fiber material and can be degraded naturally. If corn husk is widely used , not only has greater economic benefits, but also protects the environment, which is in line with the green and sustainable development strategy. [0003] On the other hand, fishing is an entertainment project that the whole peop...
