Description

인삼재배용 백색 직조필름{White weaving film for ginseng cultivation}White weaving film for ginseng cultivation

본 발명은 인삼재배용 백색 직조필름에 관한 것이다.The present invention relates to a white woven film for ginseng cultivation.

한국 내 하우스의 피복자재는 대부분 폴리에틸렌(PE) 필름으로 시설 면적 51,226 ha 중 77.1%인 39,470 ha를 차지한다. 폴리에틸렌 필름의 점유율이 높은 데는 낮은 가격, 우수한 태양광 투과율(excellent solar light transmittance, SLT), 및 가소성이 손꼽히지만 내구성은 2년 이내로 매우 짧다. 내구적인 한계를 극복하기 위해 최근 고밀도 폴리에틸렌을 가는 실로 잇따라 짠 후 계면활성제가 첨가된 저밀도 PE을 양면에 코팅하는 과정으로 직조필름이 개발되었다.Most of the covering material for houses in Korea is polyethylene (PE) film, which occupies 39,470 ha, 77.1% of the 51,226 ha of the facility. The low price, excellent solar light transmittance (SLT), and plasticity are among the reasons for the high market share of polyethylene film, but the durability is very short, less than two years. In order to overcome the durability limitation, a woven film was recently developed by woven high-density polyethylene one after another with a fine thread and then coating both sides with low-density PE with surfactant added thereto.

최근, 소득 수준이 높아지고 건강에 대한 관심이 높아지면서, 소비자의 웰빙 식품, 기능성 식품 등 안전 농산물에 대한 관심과 소비가 크게 증가하고 있다. 이러한 식품 중, 예를 들면, 인삼의 경우 한약재 중 하나로 귀하게 취급되었고 가격도 비싸게 거래되어 왔다. 근래에는, 인삼 성분에 대한 연구가 활발히 이루어지고 가공기술도 발달하면서 인삼이 빠른 속도로 대중화되고 있다.Recently, as income levels rise and interest in health increases, consumers' interest in and consumption of safe agricultural products such as well-being food and functional food has increased significantly. Among these foods, for example, ginseng has been treated as precious as one of the herbal medicines and has been traded at a high price. In recent years, research on ginseng ingredients has been actively conducted and processing technology has been developed, so ginseng is rapidly becoming popular.

이러한 인삼은, 음지성 다년생 작물로서, 즉, 인삼을 생산하기 위해서는 종자를 직파하거나 인삼을 이식하여 4 ~ 6년간을 재배하여야 하는 작물이며, 한 장소에서 오랫동안 재배되므로 병충해 및 생리 장해에 신경을 많이 써야 하는 작물에 속한다.Such ginseng is a shady perennial crop, that is, in order to produce ginseng, it is a crop that must be grown for 4 to 6 years by direct sowing or transplanting ginseng. It belongs to the crops that need to be written.

인삼은 빛을 가리지 않으면 엽소(잎타기, leaf burn)로 수량이 감소해 차광시설이 필수적이다. 과거에는 차광재로 볏짚을 사용하였으나 썩기 쉽고 SLT이 낮아 1980년대부터 PE으로 만든 사중직 검은색 차광막(four-layered black shade net)이 널리 쓰이고 있다. If you do not block the light, the quantity of ginseng decreases due to leaf burn, so a light-shielding facility is essential. In the past, rice straw was used as a light-shielding material, but since it is easy to rot and has a low SLT, a four-layered black shade net made of PE has been widely used since the 1980s.

또한, 인삼을 생산하는 기간에는, 빗물의 누수, 폭설, 태풍, 가뭄, 침관수, 고온, 저온 등의 자연재해와, 염류장해 등에 의한 황증, 적변 등의 피해가 많아 인삼의 안정적이 생산에 어려움을 주고 있다.In addition, during the ginseng production period, there are many natural disasters such as rainwater leakage, heavy snow, typhoon, drought, flooding, high temperature and low temperature, and yellowing and red color due to salt disturbance, making it difficult to stably produce ginseng. is giving

인삼이 요구하는 적합 SLT은 13 - 17%의 낮은 수준이라서 착색물질의 종류와 첨가량에 따라 혼탁도를 조절하는 방식으로 직조필름을 제작할 수 있다. 인삼 생육을 대상으로 한 선행 연구 결과를 살펴보면 적색광(red light, R)은 형태학적 기형 및 노화를 유도하고 청색광(blue light, B)은 줄기신장을 막고, 엽록소 함량을 감소시킨다. The suitable SLT required for ginseng is as low as 13 - 17%, so a woven film can be manufactured by adjusting the turbidity according to the type and amount of coloring material added. Looking at the results of previous studies on ginseng growth, red light (R) induces morphological deformities and aging, and blue light (B) blocks stem elongation and reduces chlorophyll content.

광선택성 필름은 목적에 맞는 초장(plant height)을 위해 적외선과 근적외선의 비율을 조절하는 방식으로 개발되어 왔다. 반면 인삼과 같은 광 특이적 식물에 착색 필름은 상업적으로 가능한 수단이 될 수 있지만 연구가 미비한 실정이다.The photoselective film has been developed in a way that adjusts the ratio of infrared and near-infrared rays to achieve a suitable plant height. On the other hand, a colored film for light-specific plants such as ginseng can be a commercially feasible means, but research is insufficient.

이에 본 발명자들은 내구성 및 열차단 효과가 우수하고, 인삼의 생육에 최적인 광질 및 광량으로 조절하여 폭염에 대한 대응이 가능하여, 잎이 타는 고온 장해를 경감시킬 수 있는 필름을 개발하고 본 발명을 완성하였다.Accordingly, the present inventors have developed a film that has excellent durability and thermal barrier effect, and can respond to heat waves by adjusting the light quality and amount optimal for the growth of ginseng, thereby developing a film that can reduce the high temperature damage caused by the burning of leaves and the present invention completed.

Even in midsummer, the amount of photosynthesis can be increased by raising the light-shielding film 400 before 10 am and after 6 pm when the temperature is low. In addition, in winter, in preparation for a heavy snowfall, the light-shielding film 400 may be rolled up, and in summer, the light-shielding film 400 may be rolled up in preparation for a typhoon.

여기서, 하우스 본체(100) 내부에 10 내지 20%의 광투과율을 갖는 인삼재배용 백색 직조필름(300)을 개방부(200)를 제외하고 설치하고, 외부에 75~95%내외의 차광막(400)을 개폐가능하게 설치하는 경우, 차광막(400)을 걷어 올릴 경우 13 내지 19%의 광투과율이, 차광막(400)을 내려놓을 경우 약 3%의 광투과율이 유입되도록 광투과율을 조절할 수 있다. 이와 같은 구조를 갖기 때문에 특히 인삼 재배에 최적인 광질 및 광투과율의 조건으로 조절하여 우수한 생육 환경을 제공할 수 있게 된다.Here, a white woven film 300 for ginseng cultivation having a light transmittance of 10 to 20% is installed inside the house body 100 except for the opening 200, and a light-shielding film 400 of about 75 to 95% outside. When the light-shielding film 400 is rolled up, the light transmittance of 13 to 19% is adjusted so that when the light-shielding film 400 is put down, the light transmittance of about 3% is introduced. Since it has such a structure, it is possible to provide an excellent growth environment by adjusting the conditions of light quality and light transmittance that are optimal for ginseng cultivation in particular.

<실험예 3> 필름색상에 따른 광세기 및 산란되는 정도 확인<Experimental Example 3> Check the light intensity and the degree of scattering according to the film color

필름색상에 따른 광세기(빛의 세기)를 확인하기 위해, 실시예 2의 이중구조 하우스(백색 직조필름을 적용)와 비교예 4의 이중구조 하우스(비교예 1의 청색 직조필름을 적용) 및 비교예 2의 이중구조 하우스(상기 실시예 1-4의 투명 직조 필름을 적용)의 광세기를 분광광도계를 사용하여 파장별로 측정하였다In order to check the light intensity (intensity of light) according to the film color, the double structure house of Example 2 (applying a white woven film) and the dual structure house of Comparative Example 4 (applying the blue woven film of Comparative Example 1) and The light intensity of the double structure house of Comparative Example 2 (applying the transparent woven film of Examples 1-4) was measured for each wavelength using a spectrophotometer.

그 결과, 도 12 (a)에 나타낸 바와 같이, 청색 직조필름을 적용한 비교예 4의 경우, 청색 파장영역에서 광세기가 상대적으로 강한 것을 확인하였으나, 청색 파장 영역을 제외한 나머지 파장대에서는 실시예 2 또는 비교예 2 대비 광세기가 약한 것을 확인하였다. 또한, 실시예 2 및 비교예 2의 경우, 전체적인 파장에 걸처 비교적 고른 광세기를 나타내는 것을 확인하였다.As a result, as shown in Fig. 12 (a), in the case of Comparative Example 4 to which the blue woven film was applied, it was confirmed that the light intensity was relatively strong in the blue wavelength region, but in the other wavelength bands except for the blue wavelength region, Example 2 or It was confirmed that the light intensity was weak compared to Comparative Example 2. In addition, in the case of Example 2 and Comparative Example 2, it was confirmed that the light intensity was relatively even over the entire wavelength.

또한, 광합성유효량 광량자속 밀도(PPFD)는 분광조도계로 측정하였으며, 300 내지 800nm 사이의 광량자 밀도를 측정하였다. 인삼의 생육에서 광이 미치는 영향은 하우스 내부에 광이 한쪽으로 치우치는 것보다 광이 산란되어 하우스 내부로 골고루 들어오는 것이 인삼 생육에 최적인 조건이라 할 수 있다.In addition, the photosynthetic effective amount photon flux density (PPFD) was measured with a spectrophotometer, and the photon density between 300 and 800 nm was measured. As for the effect of light on the growth of ginseng, it can be said that the optimal condition for ginseng growth is that the light is scattered and enters the house evenly rather than the light is biased to one side inside the house.

그 결과, 도 12 (b)에 나타낸 바와 같이, 외부(태양광)의 경우, 총 PPFD와 산란된 PPFD이 큰 차이를 보이는 것을 확인하였으며, 투명 직조필름을 적용한 비교예 2의 경우와 유사한 것을 확인하였다. 반면에, 청색 직조필름을 적용한 비교예 4 및 실시예 2의 경우, 총 PPFD와 산란된 PPFD와 유사한 수준이나, PPFD 값이 청색 직조필름을 적용한 비교예 4 대비 본 발명의 백색 직조필름을 적용한 실시예 2의 PPFD 값이 더 높은 것을 확인하였다. As a result, as shown in Fig. 12 (b), in the case of external (sunlight), it was confirmed that the total PPFD and the scattered PPFD showed a large difference, and it was confirmed that it was similar to the case of Comparative Example 2 to which a transparent woven film was applied. did On the other hand, in Comparative Examples 4 and 2 to which the blue woven film was applied, the total PPFD and scattered PPFD were similar to those of the total PPFD, but the PPFD value was applied to the white woven film of the present invention compared to Comparative Example 4 to which the blue woven film was applied. It was confirmed that the PPFD value of Example 2 was higher.

따라서, 상기 실험 결과로 인해, 본 발명의 백색 직조필름을 사용할 경우, 하우스 내부로 직사광으로 들어오는 것이 아니라, 하우스 내부로 빛을 골고루 산란시키고, 높은 PPFD 값을 가져 인삼의 광합성을 촉진시켜, 인삼 생육을 촉진시키는 효과가 있는 것을 확인하였다.Therefore, due to the above experimental results, when the white woven film of the present invention is used, the light does not enter the house as direct sunlight, but evenly scatters the light inside the house and has a high PPFD value to promote photosynthesis of ginseng, ginseng growth It was confirmed that the effect of promoting
