Embodiment Construction

[0034] The present invention can be implemented in various forms, and therefore is not limited to the embodiments described here.

[0035] Throughout the specification, when it is mentioned that a part is "connected (connected, contacted, combined)" with other parts, it includes not only the case of "direct connection" but also the case of "indirect connection" with other parts in between. Moreover, when it is mentioned that a certain part "includes" a certain structural element, if the context does not specify otherwise, it means that it may also have other structural elements, rather than excluding other structural elements.

[0036] The terms used in this specification are used only to describe specific embodiments, and are not intended to limit the present invention. Expressions in the singular include expressions in the plural unless the context clearly indicates a different meaning. In this specification, terms such as "comprising" or "having" should be understood as th...

Abstract

Disclosed are: a biodegradable coating composition for a mulching paper; and a mulching paper. Out of these, the biodegradable coating composition for a mulching paper comprises: 45-72 parts by weight of spring water, the spring water being made by immersing a mineral material powder, which has a particle size distribution of 400-700 mesh and includes a sericite powder, in water contained in a container for 10-20 days to thereby allow mineral components of the mineral material to dissolve in water; 3-8 parts by weight of a charcoal powder having a particle size of 1,000-3,000 mesh; 8-13 parts by weight of a calcium liquid; 5-15 parts by weight of a filler containing a sulfur powder, an illite powder, and an expanded vermiculite powder; 5-8 parts by weight of starch; and 10-20 parts by weight of an additive.

Description

technical field [0001] The invention relates to the field of mulch paper covering the soil surface where crops grow, and in detail, relates to a biodegradable coating composition coated on the surface of the mulch paper and the mulch paper coated therewith. Background technique [0002] Mulching refers to the act of covering the surface of cultivated land when cultivating crops. The purpose of its implementation is to prevent soil erosion, maintain soil moisture, adjust ground temperature, suppress weeds, prevent soil infectious bacteria, and prevent soil pollution. [0003] That is, as a method of covering the soil surface of the rooting cultivated crops, the mulch film has an anti-erosion effect of preventing the rooting of the cultivated crops from being lost due to floods, and to a certain extent inhibits the evaporation of water required for growth. It plays a role in regulating the water used for cultivating crops. [0004] Moreover, by physically blocking the sunligh...
