Description

Mulching paper manufacturing device using non-woven paper

The present invention is to laminate a powder sheet on a pre-made eco-friendly non-woven fabric, and then sequentially apply an application material containing a mineral and a nutrient mixture for various effects to produce mulching paper having various effects while lowering the price than before It relates to a manufacturing device that makes this possible.

In general, when herbicides and pesticides are excessively sprayed on farmland for weeding and pest eradication, problems such as contamination of farmland, disturbance of ecosystem, and inducing disease by human absorption occur.

Therefore, nitrogen fertilizer or manure is applied to farmland to protect farmland. However, nitrogen fertilizers cause water pollution. In addition, the manufacturing process of manure is complicated, and there is a problem that moisture infiltrates into the land during the manufacturing process and pollutes the water quality.

Due to this, many farmers are showing a lot of interest in growing crops through organic farming or eco-friendly farming.

Recently, mulching films such as polyethylene or polyvinyl chloride are used in farmland. Mulching film can reduce the use of herbicides by covering the surface of the soil when growing crops, retaining soil moisture and inhibiting weed growth.

However, since the conventional mulching film does not decompose naturally, there is a problem in that it must be collected one by one later. In some cases, mulching films synthesized with degradable substances are used, but polyethylene and polyvinyl chloride have a long decomposition process, so the mulching film accumulates in the soil and contaminates the land. There was a problem in that if it blows, it flies off and causes the crops to fall.

Accordingly, there is an urgent need to develop a device capable of solving these problems.
