재배 생력용으로 많이 이용되고 있는 멀칭 방법이 삽주의 생육에 미치는 효과를 구명하여 최적 멀칭방법을 확립하고자 무멀칭, 볏짚, 투명비닐, 흑색비닐, 이들 비닐과 왕겨를 혼용한 멀칭이 삽주의 어린싹, 초기 및 후기 생장과 수량에 미치는 영향을 조사하였던 바 그 결과를 요약하면 다음과 같다. 1. 삽주의 어린싹 무게는 투명 비닐을 이용한 멀칭에서 가장 많았던 반면, 어린싹과 관련된 형질중에서는 엽수, 어린싹의 길이는 볏짚을 이용한 멀칭에서 가장 작았다. 2. 생장초기에는 볏짚을 이용한 멀칭시 엽수, 근수, 경수, 엽폭, 지상부 및 근경의 생체중이 가장 적었던 반면, 왕겨와 흑색비닐 혼합멀칭시 뿌리 관련 형질인 근수, 근경중 및 근중이 가장 많았다. 3. 생장후기에는 지온이 낮았던 생장초기의 멀칭효과가 고온기를 경과하면서 그 효과가 사라져 생장 및 형태적 형질에서는 멀칭처리간 차이가 거의 없었다. 4. 단위면적당 수량과 상품 수량은 볏짚 단독멀칭과 왕겨와 흑색비닐의 혼합멀칭 에서 가장 높았다.

Background: This study determined the effects of mulching, an environment friendly organic cultivation method, on antioxidant compound contents and growth in Codonopsis lanceolata, commonly known as Deodeok. Methods and Results: C. lanceolata was treated by mulching with several different methods (a non-woven fabric, biodegradable film, or rice husks) and also treated with hand weeding. A non-treatment plot was used as a control. The growth and levels of weed control in C. lanceolata were better in plants cultivated under mulching treatments (non-woven fabric, biodegradable film, and rice husks) than in those under non-mulching treatments (hand weeding and non-treatment). The contents of antioxidant compounds, such as total flavonoids, phenolics, and anthocyanins, were highest under the biodegradable film treatment, followed by the non-woven fabric treatment, rice husks treatment hand weeding, and non-treatment. There were identifiable differences in DPPH and ABTS activity in comparison to antioxidant compound content by solvent fractions. Mulching treatments resulted in higher DPPH scavenging activity in water and ethyl ether fractions and ABTS scavenging activity in n-butanol fractions than in other fractions, as opposed to hand weeding and non-treatment groups, although total activity of DPPH and ABTS did not increase with mulching treatments. Conclusions: Mulching C. lanceolata with biodegradable film and non-woven fabric is an effective method for improving plant growth and inhibiting the occurrence of weeds as well as for increasing antioxidant compound content and altering antioxidant activity.

안개초 절화 재배시 토양피복재료 및 피복방법에 따른 잡초 발생량 및 안개초 개화특성 등을 조사하였다. 잡초 발생량은 무피복 $146.2g{\cdot}m^{-2}$(건물중)인 반면 흑색과 녹색 폴리프로필렌 부직포 전면피복은 $4.1{\sim}4.2g{\cdot}m^{-2}$으로 거의 발생되지 않았으며, 제초 소요인원도 무피복은 27.9명/10a/년인데 반해 전면피복은 2.4명/10a/년이었다. 여름 절화작형시 개화는 무피복과 골 피복이 늦었으며, 화경장, 측지수, 절화장, 화수폭 및 화경 강도는 흑색과 녹색 부직포 전면피복이 우수하였고, 절화량은 흑색 PE필름, 녹색과 흑색 부직포 전면피복에서 많았다. 월하 후 안개초 고사주율은 흑색 부직포 골 피복처리에서 12.4%로 가장 낮았고, 녹색 부직포 피복처리가 19.0% 정도였으며, 흑색 PE 필름 전면 피복처리가 39.0%로 가장 높았다. 가을 절화작형 역시 화경장, 측지수, 절화장 및 화경 강도는 흑색과 녹색 부직포 전면피복이 우수하였고, 절화량은 녹색 부직포가 가장 많았다. 로젯트 발생률은 골피복보다 전면피복이 낮았으며, 피복재료별로는 녹색 부직포 전면피복이 가장 낮았고, 다음은 흑색 부직포, 흑색 PE 필름 전면피복이 낮았다. 따라서 안개초 절화재배시 녹색 부직포 전면 피복처리가 잡초 발생억제와 절화품질 향상 및 절화량 증가에 효과적이라고 생각된다.

The study was performed in order to derive the management methods of revegetation space on embankment upper in the shoulder of expressway. The pilot study was conducted in 2013 on the test road section of the Jungbu Inland Expressway (Smart Highway) and continues to be monitored until 2020. In the test, three commonly used methods for weed control were applied. In the early two to three years, most of the methods were effective in controlling weeds. However, at the end of six years, weed suppression effects were different for each treatment. Vegetation coverage was 90% in the untreated control, 70-80% wood chip mulching method, 50-60% solidification method, and 20% sheet mulching method. The sheet method was found to be the most effective given the low vegetation coverage was effective in controlling weeds. The wood chip mulching method is promoting weed growth over time, and weeds are invading as the effect of soil hardening is reduced in the place where the soil hardener is treated. Among the methods applied in the test, mulching the sheet is the most effective, but it is important to use a durable sheet. In the future, it is necessary to find ways to control weeds on road shoulders, considering both economic and environmental aspects. For the proper management in the shoulder of expressway set target zone is needed. Clear standards for weed control on expressway should be established. And the technology to be applied must be durable for 3 years or more and must be able to suppress the amount of weeds to a level of 20% or less.

A field study was conducted to determine the runoff loss of N and P in small scale of red pepper field plots (10% slope), consisting of three different plots with black polyethylene vinyl mulching (mulching), ridge without mulching (ridge), and flat without ridge and mulching (flat). Composted manure and urea as a basal application were applied at rates of $20MT\;ha^{-1}$ and $93kg\;N\;ha^{-1}$, respectively. Urea at $189kg\;N\;ha^{-1}$ and fused phosphate at $67kg\;P_2O_5\;ha^{-1}$ were additionally applied on June 25 with different fertilization methods, broadcast application in flat plot and hole injection in ridge and mulching plots. Plant uptake of N and P was positively correlated with their respective concentrations in surface soil: mulching > ridge > flat plots. The runoff loss by soil erosion was higher in flat plot than ridge and mulching plot with contour line. Nitrate loss by the runoff water had no significant differences among three surface management practices, but the higher average value in ridge and mulching plots than flat plot. Especially, the flat plot had no phosphate loss during summer season. This is probably due to low labile P content in surface soil of flat plot. In the summation of soil and water loss, flat plot was higher in N and P loss than ridge and mulching plot with contour line. Nevertheless, the nitrate and phosphate loss by runoff water could be more important for non-point source management because the water could meet the river easier than eroded soil because of re-deposition around slope land.

Enlargement of street tree planting area is the proper and effective solution to reduce carbon dioxide. This solution bases on the ability of carbon storage and uptake by tree metabolism. However, the circumstance of road side has fatal disadvantages in tree metabolism such as growth and maturity because cutting and filling of roadsides cause unnatural soil composition. In this point, early rootage of street tree is the main factor of reducing carbon dioxide. This study aimed to find a appropriate transplantation planting method for sound and rapid rootage of street tree. For the study, Korean Mountain Ash(Sorbus alnifolia) were used for experimental groups. The groups were categorized by three groups such as trees produced on container with mulching treatment, trees produced in outdoor with mulching treatment, trees produced on container with weeding treatment. Each group consisted 10 trees with same size and transplanted in experimental site. Five months after transplanting, each group was estimated the biomass and carbon storage through a direct harvesting method. According to results of the study, the carbon storage of trees produced on container with mulching treatment is 42% more than trees produced in outdoor with mulching treatment. And the carbon storage of trees produced on container with mulching treatment is 19.5% more than trees produced on container with weeding treatment. These results may imply that transplantation of container produced tree with mulching treatment is the most rapid rootage among other groups. The weeding treatment is more effective than mulching treatment for rapid rootage of street trees.

This experiment was conducted to elucidate the effects of mulching materials and removing time of the transparent polyethylene (PE) film on the growth of garlic at Uiseong experimental field, Korea. The experimental mulching materials comprised of transparent polyethylene film (0.025 mm) and net polyethylene (NPE). Plant height and leaf number of garlic were highest at PE treatment when the PE removing date was March 18 and this treatment also promoted the no. of cloves. Length of leaf sheath and bolting rate were highest and bulb weight loss rate was lowest at PE + NPE treatment when the PE removing date was March 18. But clove number was the lowest in this treatment compared to conventional PE film treatment. Conventional mulching method accelerated secondary growth rate but bulb weight loss was vice versa. There were statistically no differences in bulb diameter among treatments but conventional treatment positively focused on bulb diameter. Whenever PE film remove can suppress weeds compared to no mulching treatment but the dry weight of weeds were increasing trends as the removal dates of PE film were delayed. Transparent PE or PE + NPE treatments can be recommended to grow best quality garlic when PE film removing date is March 18.
