느타리버섯 봉지 재배의 봉지직경 및 배지량에 따른 생육특성을 비교하여 효율적인 봉지규격을 추정하고자 미송톱밥, 비트펄프, 면실박을 부피비로 50 : 30 : 20으로 혼합한 배지로 봉지 직경 $10{\sim}20\;cm$, 배지량 $600{\sim}2,500\;g$/봉지 범위에서 시험 한 결과 봉지직경이 작을수록 배지량이 많아짐에 따라 배지길이가 길어져 배양일수가 지연되었고 이에 따라 총재배기간이 길었다. 또한 2주기까지의 수량은 같은 봉지직경에서 배지량이 클수록 증가하였고 배지량이 1,200 g/봉지보다 많으면 생물학적효율은 감소하여 100% 보다 낮았으며, 같은 배지량에서 봉지 직경에 따른 수량은 큰 차이 없으나 회수율은 봉지직경이 14 cm 보다 크면 감소하였다. 따라서 재배기간, 수량, 생물학적효율 등을 고려한 효율적인 봉지직경은 $10{\sim}14\;cm$, 배지량 $800{\sim}1,200\;g$/봉지 내외로 추정되었다.

Dewatering sludge using inorganic chemicals with polymer has been evaded for reuse on account of the risks of high heavy metals contained and soil acidification. Composting feasibility of coagulation & dewatering sludges produced from livestock waste treatment plant was investigated. The results of analysis prove that dewatering sludge is valuable matter with suitable elements for composting if high quality ferric chloride ($FeCl_3$) is used for coagulation & dewatering process. In pot-cultivation of harvestes, using effects of dewatering sludge improved with lime treatment was very effective. The results of pot-cultivation proved that harms of crops according to different acid tolerances were not detected. But it was not applied to crops with weak acid tolerance or greenhouse for free from gas damage. Also, Further studies and monitorings are necessary to use sludges because results of pot-cultivation were generated differently by characteristics of soil, nutrient demand of plants, mature degree of sludge, consecutive cultivation and etc.

Background: Ginseng (Panax ginseng Meyer) is a perennial plant belonging to the Araliaceae family that is known to have various beneficial effects including improving memory loss and spatial cognitive ability, and anti-cancer and anti-diabetes activity. Its functional benefits also include improving liver function, regulating blood pressure, stress, and providing antioxidant activity. Usually, various agrochemicals are used in cultivating ginseng preventing from many diseases. Methods: FCGP (field cultivated ginseng in pot) was implemented by imitating MCWG (mountain cultivated wild ginseng). Pesticide analysis of pot cultivation was carried out and the contents of bioactive components such as ginsenoside were also analyzed. Results: FCGP ginsenoside content was higher than that of FCG (field cultivated ginseng) and MCWG. FCGP has been shown to have a relatively high antioxidant effect compared with cultivated ginseng. Conclusion: It was confirmed that ginseng can be grown for 6 years without resorting to use of pesticides. In addition, it was confirmed that effective accumulation of physiologically active ingredients such as ginsenoside is possible. Our result represents FCGP is a novel method of pesticide-free ginseng cultivation

This study was carried out to investigated the water requirement of twisted sweet peppers which are cultivated in a green house. The meteorological conditions during the experiment period was close to that of normal year except the temperature and relative humidity. The growth status was improved with the increased saturation ratio. The range of the variation of daily water requirement were very large. The peak consumption occurred in the early August. And the higher saturation ratio resulted in higher water requirement. The total water requirement were about 57.180g/d/plant for pot with 100% (P100) of saturation , about 38.700g/d/plant for pot with 80%(P80) of saturation , about 23,720g/d/plant for pot with 60%(P60) of saturation, and about 53, 390g/d/plant for field cultivation in the green house, respectively. The water requirement was correlated with average ambient temperature and growing status, while no significant correlation were found between water requirement and minimum relative humidity or intensity of solar radiation. And the higher correlation was shown as the saturation ratio was increased. The transpiration coefficients of twisted sweet pepper were 378.0g/g for field cultivation in the green house, 363.3g/g for P100, 338.7g for P80 which was the smallest among pot cultivation , and 472.1g/g for P60 , respectively.

The initial investment of rice cultivation by mechanical technique was high. This was only due to the cost of planting machine. We analysed the overall cost (without machine cost) and benefits of the two methods, it manifested that the mechanical method is very much beneficial over traditional rice cultivation technique. We observed that the requirement of soil, irrigation water, number of seeds etc. decreased in mechanical cultivation technique while net income increase by 13.07% with 80% government subsidy. Furthermore, the initial rooting was quicker, growth and development of pot raised seedlings was better than the traditional technique. Hence, this technique can give better return to the farmers with the help of government subsidy.

노루궁뎅이버섯의 재배방법에 따른 수량은 병재배로 재배하였을 때 356 g/850 ml으로, 봉지(pot)재배하였을 때의 810 g/2500 ml보다 더 높았다. 그러나 회수율은 병(850 ml)에 재배하였을 때 147.8%로 봉지(pot)에 재배하였을 때의 114.3% 보다 높았다 발이 유기시 균긁기는 하지 않은 것이 좋았으며 특히 병마개를 막아둔 상태에서 발이시키는 방법이 수량도 가장 많고 생물적 효율도 높았다. 노루궁뎅이버섯의 원목재배 수종은 참나무, 물오리나무, 포플러, 아카시나무 원목 순으로 좋았다. 참나무원목은 수량이 $1195.5\;g/0.1\;m^3$, 생물학적 효율이 17.3%, 초발이 소요일수는 69일, 개체중은 143 g이었다.

This study was performed to figure out water consumption of the twisted sweet pepper in a greenhouse. Obtained results are as follows; 1. The ambient temperature was nearly same as the normal year, while the average air temperature and the relative humidity in the green house were little bit higher than those of the outside condition. The transparency of the greenhouse roof was approximately 50%. The total amount of rainfall during the irrigation period was 1,040㎜ which is 350㎜ higher than 1997 during the same period. 2. In case of pot cultivation, as the saturation ratio was increased, the aeaf area and plant height and yield were also increased. The yield from the field cultivation was higher than the average yield from the pot cultivations which are treated by three levels of saturation ratio. 3. The variation of daily consumptive use of the twisted sweet pepper was very large in it's range. In case of the pot cultivation, as the saturation was increased, the daily and the total consumptive use were increased. 4. The daily consumptive use was strongly correlated with the ambient temperature, while it was weakly correlated with the relative humidity and solar radiation. 5. There were close correlation between plant environment; leaf area, plant height and yield, and consumptive use. As the saturation ratio was increased, the correlation between those plant factors and consumptive use was getting stronger.

본 연구에서는 생태녹화용 유묘 생산에 적합한 재배용기를 선별하기 위하여 다양한 재배용기가 자작나무 유묘에 미치는 영향을 조사하였다. 실험에 사용한 용기는 일반용기, 일반용기 내부에 융기선 5 mm와 10 mm 설치, 일반용기 표면에 세로 절개홈 있는 배광성용기, 배광성용기 내부에 융기선 5 mm와 10 mm를 설치한 용기이었다. 재배용기에 따른 유묘생장 특성은 다음과 같다. 실험결과 온실 재배에서는 관수, 온도 등 관리도가 높아 수고, 가지수, 근원경 생장의 유의차가 없었으나, 뿌리생장은 유의차를 보이며 배광성용기에서 우수했다. 일반용기는 뿌리가 나선형의 비정상으로 자란 반면 배광성용기는 뿌리가 수직으로 자랐다. 노지이식 후 재배용기 처리에 따라 유의차를 보이며, 수고, 가지수, 근원경, 뿌리생장 모두 배광성용기에서 자란 유묘가 가장 우수한 것으로 나타났다. 배광성용기에서 자란 유묘의 경우 뿌리가 수직으로 생장해 노지 이식 후 뿌리활착 및 생장이 우수했으며, 용기내부에 설치한 융기선은 5 mm이내가 적정한 것으로 나타났다. 따라서 배광성용기를 사용한 생태녹화용 자작나무 유묘에서 수고, 가지수, 근원경 및 뿌리생장에 큰 효과를 보여 배광성용기가 유묘생산에 적합한 것으로 판단되었다.

This study assessed the fertilizing value of struvite deposit recovered from swine wastewater in cultivating Chinese cabbage. Struvite deposit was compared with commercial fertilizers: complex, organic and compost to evaluate the fertilizing effect of struvite deposit. Laboratory pot test obviously presented that the struvite deposit more facilitated the growth of Chinese cabbage than organic and compost fertilizers even though complex fertilizer was the most effective in growing Chinese cabbage. It was revealed that the growth rate of Chinese cabbage was simultaneously controlled by phosphorus (P) and potassium (K). Also, the nutrients such as nitrogen (N), P, K, calcium (Ca) and magnesium (Mg) were abundantly observed in the vegetable tissue of struvite pot. Specifically, P was the most abundant component in the vegetable tissue of struvite pot. Meanwhile, the utilization of struvite as a fertilizer led to the lower accumulation of chromium ($Cr^{6+}$) than other pots, except for compost fertilizer pots, and no detection of cadmium (Cd), arsenic (As) and nickel (Ni) in the Chinese cabbage. The experimental results proved that the optimum struvite dosage for the cultivation of Chinese cabbage was 2.0 g struvite/kg soil. On the basis of these findings, it was concluded that the struvite deposits recovered from swine wastewater were effective as a multi-nutrient fertilizer for Chinese cabbage cultivation.
