본 발명은 멀칭재 제조 방법에 관한 것으로, 보다 상세하게는 반탄화 목분으로 이루어져 자연 분해가 손쉽게 이루어지도록 하면서 토양오염을 야기하지 않고 별도의 수거 작업이 필요 없는 반탄화 목분을 이용한 멀칭재 제조 방법에 관한 것이다.The present invention relates to a method for manufacturing a mulching material, and more particularly, to a method for manufacturing a mulching material using torrefied wood powder, which is made of torrefied wood powder so that natural decomposition is easily achieved, does not cause soil contamination, and does not require a separate collection operation. will be.
일반적으로 멀칭(mulching)은 농작물을 재배할 때 경지토양의 표면을 덮어주는 것으로, 토양침식방지, 토양수분유지, 저온조절, 잡초억제, 토양오염방지 등의 목적으로 사용되고 있다.In general, mulching is used to cover the surface of cultivated soil when cultivating crops, and is used for purposes such as preventing soil erosion, maintaining soil moisture, controlling low temperatures, suppressing weeds, and preventing soil contamination.
이를 보다 상세하게 설명하면, 뿌리를 내리고 있는 재배 작물의 토양 표면을 덮어주는 방법으로, 고랑부분(재배작물이 뿌리를 내리고 있는 부분)이 수해로 유실되는 것을 방지하는 침식방지 기능을 수행하고, 또한 생육에 필수적인 수분증발을 일정부분 억제하여 일정 범위내에서 재배작물을 위한 수분조절 역할을 수행하기도 하였다.To explain this in more detail, it is a method of covering the soil surface of cultivated crops that are rooted, and performs an erosion prevention function to prevent the furrow (the part where cultivated crops are rooted) from being lost due to flood damage, and It also played a role in controlling moisture for cultivated crops within a certain range by suppressing a certain amount of moisture evaporation essential for growth.
이와 같은 멀칭에 사용되는 멀칭재로는 초기에는 볏짚, 조릿짚, 목초 등과 같은 친환경 재료를 사용하였으나, 오늘날에 이르러 작업이 간편하고 확보가 용이한 폴리에틸렌이나 폴리염화비닐과 같은 비닐 재료를 많이 사용하고 있다.As a mulching material used for such mulching, eco-friendly materials such as rice straw, straw straw, and grass were used in the early days, but today, vinyl materials such as polyethylene or polyvinyl chloride, which are easy to work with and easy to secure, are widely used. there is.
그러나, 상기한 비닐 재료들은 지면에 노출되어 있는 비닐하우스용 비닐과 달리 흙 속에 묻은 후에 수거하는 작업을 거쳐야 하는데, 회수를 위한 작업강도가 매우 높을 뿐만 아니라 농촌인력의 노령화로 인하여 완력으로 제거되기가 어렵고 대부분의 비닐 멀칭지가 흙 속에 영구적으로 남게 되는 문제가 있었다.However, unlike vinyl for greenhouses exposed on the ground, the above-mentioned vinyl materials have to be collected after being buried in the soil. It was difficult and had the problem of most vinyl mulches being left permanently in the soil.
특히, 흙 속에 잔존하는 비닐 멀칭지는 재질의 특성상 통기성이 매우 불량하여 토양오염의 주요 원인이 되는데, 이처럼 제거되지 않는 비닐 멀칭지가 해마다 더욱 늘어난다는데 더욱 큰 문제가 있고 더욱이 회수율도 55% 미만에 그치고 있다.In particular, the vinyl mulching paper remaining in the soil is very poor in air permeability due to the nature of the material, which is a major cause of soil contamination. .
이러한 문제를 해결하기 위하여 자연 상태에서 자연분해가 가능한 멀징재에 대한 연구가 진행되고 있는데, 이런 자연 분해 가능한 멀칭재도 베이스폴리머로서 합성수지를 이용함으로써 토양 미생물에 의한 자연분해에 한계가 있다는 문제점이 있었다.In order to solve this problem, research on mulching materials that can be naturally degraded in nature is being conducted. However, since these naturally degradable mulching materials use synthetic resin as a base polymer, there is a problem in that there is a limit to natural degradation by soil microorganisms.
이에 본 발명은 상기와 같은 종래의 제반 문제점을 해소하기 위해 안출된 것으로,Accordingly, the present invention was made to solve the above conventional problems,
