지렁이 분립을 첨가한 유기상토가 벼의 유식물체 생육에 미치는 영향 -느타리버섯 폐배지로 생산한 분립의 첨가-

이주삼,김인수,Lee, Ju-Sam,Kim, In-Soo 한국유기농업학회 2009 韓國有機農業學會誌 Vol.17 No.1

저면도포 무처리구에서 유기상토에 느타리버섯 폐배지로 생산한 분립 4-6%의 첨가비율에서 벼의 유식물체의 생육이 가장 좋았다. 저면도포 처리구에서는 대조구(유기상토 100%)에서 벼의 유식물체의 생육이 가장 좋았는데, 이는 신장된 뿌리가 토양표면에 시용된 분립으로부터 생육에 필요한 양분을 흡수하였기 때문으로 추정된다 따라서 장기간 육묘할 경우에는 유기상토에 분립을 혼합하지 않고 토양표면에 분립 100%를 시용하는 저면도포 방법이 효율적이라고 생각된다. 느타리버섯 폐배지로 생산한 분립은 중금속 함량이 낮아서 안전성이 높고. 양분공급능력이 높은 유기상토재로서 이웅 가능성이 높다고 판단된다. 유기상토의 양분공급능력을 높여 유식물체의 생육을 촉진하기 위해서는 분립과 같은 상토재의 첨가를 통하여 질소함량은 높이고, 탄질율은 낮추는 것이 필요하다고 판단된다. In this paper, we assessed the growth of rice seedlings(Chucheong variety) in commercial organic growth medium that was substituted with different ratios of vermicast of oyster mushroom waste grown under potting alone, and potting and floor layering treatment. The commercial organic growth medium was substituted with vermicast at ratios of control, 2%, 4% and 6%, respectively. The control consisted of commercial organic growth medium alone without vermicast. Incorporation of $4%{\sim}6%$ vermicast of oyster mushroom waste into a commercial organic growth medium enhanced the growth of rice seedlings significantly as compared to commercial organic growth medium alone(control), and 2% amended with vermicast in potting treatment. This results demonstrate that substitution with low ratios of vermicast($4%{\sim}6%$) will promote growth of rice seedlings. The growth of rice seedlings in commercial organic growth medium alone without vermicast was enhanced significantly as compared to the substituted with vermicast in floor layering treatment, it may due to nutrient uptake by elongated root from the vermicast when applied to on the floor layering. Floor layering treatment is an effective method for potting processing of vermicast. The vermicast of oyster mushroom waste should have a high safety and great potential as materials of growth media for increasing plant growth, either as soil conditioner, or as substitution or amendments to commercial organic growth medium. For the enhanced growth of rice seedlings, demand to increase with total nitrogen, and decrease with the carbon and nitrogen ratio(C/N) of commercial organic growth medium supplied by such as vermicast.

This experiment was carried out to the effects of population density and C/N ratios of feed on the growth, reproductive effciency and cast producation of the earthworm(Eisenia foetida). The population densities of 50, 100, 150, 200 and 250 individuals of the earthworm fed with different C/N ratios of 25, 35, 45 and 55 cow manures were studied in rearing box($6,400cm^3$), and at the fertility stage during a period of 60 days. The results were summarized as follows; The survial rate(SR), increasing rate(IR), reproductive efficiency(RE) and cast production of the earthworms showed highest values in C/N ratio of 25. These results may indicate that C/N ratio of 25 is a very favourable feed for the growth of the earthworms. The survial rate(SR) indicated significant positive correlation with reproductive efficiency(RE) in different C/N ratios of feeds. The survial rate(SR) showed highest values in population densities of $50{\sim}100$ worms/$6,400cm^3(64.0{\sim}128.0cm^3/worm$). On the contrary, increasing rate(IR) tended to decreased with the increased population densities. The survival rate(SR) indicated significant negative correlation with reproductive efficiency(RE) in different population densities of the earthworms. The cast production estimated were $31.6mg{\sim}67.4mg/day/worm$ grown in optimum population densities($50{\sim}100\;worms/6,400cm^3$). The earthworm casting are an excellent soil conditioning material or organic fertilizer sources with a high chemical composition and their physical properties.

N/A This experiment was carried out to compare the varietal differences in regrowth capacity of three varieties of meadow fescue, basing on the data of the dry weight of a plant(DW) of the tad cutting and its related characters of the 1 st cutting. The results are summarized as follows; 1. The dry weight of a plant(DW) of the 2nd cutting showed positive significant correlations with leaf weight of a plant(LW), stem weight of a plant(SW), weight of a tiller per plant(WT), leaf area per plant(LA), stem area per plant(SA), stem thickness(ST) and the efficiency of dry matter production per leaf area(DW/LA) of the 1st cutting. 2. Specific leaf weight(SLW) and the efficiency of dry matter production per leaf area(DW/LA) at the 1st cutting became to have more influence on the increase of specific stem weight(SSW) and the efficiency of dry matter production per stem area(DW/SA) at the 2nd cutting. 3. Specific stem weight(SSW) of the 1st cutting in M variety had positive significant correlations with the number of tillers per plant(N`I~ and the dry weight of a plant(DW) of the 2nd cutting. 4. The values of the efficiency of specific stem weight on the regowth(ESSW) were 4.09, 3.60 and 2.13 in M, Leto and Bundy, respectively. 5. The relationship between the dry weight of a plant(DW) of the 2nd cutting and the efficiency of spec stem weight on the regrowth(ESSW) was non-significant correlation(r = 0.0541). But, there was negative significant correlation in M(r=-0.9197^(**)) and in Leto(r=-0.8660^*), but non-significant correlation in Bundy(r = -0.3802), respectively. 6. The efficiency of specific stem weight on the regrowth(ESSW) is an effective functional factor fox the decision of regrowth capacity of the varieties.

이주삼,이필원,Lee, Ju-Sam,Lee, Pil-Won 유기성자원학회 2002 유기물자원화 Vol.10 No.4

본 연구는 vermicomposting에 의하여 한우분을 처리할 경우, 지렁이의 생육과 분립생산에 알맞는 적정한 인과 칼슘의 첨가수준을 추정하였다. 인 2%수준에서 실험 종료시 생체중, 증체속도가 높았지만, 칼슘 첨가수준간에서는 유의한 차이가 인정되지 않았다. 분립의 유효 인 함량과 칼슘함량의 비율은 인 2% 수준에서 1.04-1.20:1의 범위였고, 인 4%수준에서는1.28-1.37:1의 범위를 나타내었다. 유기물의 체 조직으로의 전환율은 인 2%수준에서 0.35%-0.41%의 범위, 4%수준에서는 0.25%-0.40%의 범위를 나타내었다. The purpose of this study was estimate the optimal phosphorus and calcium levels of Korean native cow manure on the growth and cast production of earthworm(Eisenia foetida). Phosphorus and calcium levels supplemented to cow manure were 0%(without earthworm), 2% and 4%, and 0.01%, 0.02%, 0.04% and 0.06% of the cow manure by weight, respectively. The maximum fresh weight and increasing rate of earthworm were obtained with 2% phosphorus level, but there was not significant differences between calcium levels. The ratios of available phosphorus to calcium contents of cast were 1.04-1.20:1 with 2%, and 1.28-1.37:1 with 4% phosphorus levels. Conversion rate of organic matter to earthworm tissue were 0.35-0.41% with 2%, and 0.25-0.40% with 4% phosphorus levels.

This experiment was carried out to investigate the effect of supplementing phosphorus to Korean cow manure on the growth and cast production of earthworm(Eisenia Foetida), and to estimate the optimal phosphorus level for the growth and cast production of earthworm and ratios of available phosphorus and calcium content of cast in optimal phosphorus levels. Phosphorus supplementing ratios to Korean native cow were 0, 1%, 2%, 4% and 8A%, respectively. The volume of raising box was 3375cm$^3$(15$\times$15$\times$15cm), and 500g of cow manure filled up to 10cm layer. Raising density was 90㎤ per worm during the experimental period(60 days). The maximum fresh weight and cast production of earthworm were obtained at 2~4% and 1% levels of phosphorus supplementation to Korea native cow manure. The total phosphorus and available phosphorus contents of earthworm tissues were not significant among in all treatments. There was a positive significantly differences between total phosphorus and available phosphorus of cast and residual matters. Available phosphorus content of cast were ranged from 9.3mg/g to 17.3mg/g at 1~4% levels of phosphorus supplementation. Ratios of available phosphorus and calcium contents of cast were 1.94~3.15:1 and 0.87~1.33:1 at 2~4% and 0~1% levels of phosphorus supplementation.

Vermicomposting 조건에서 분리한 Phytase의 활성화의 인 함량에 미치는 영향

이주삼 한국축산환경학회 2000 축산시설환경학회지 Vol.6 No.1

지렁이, vermicomposted com manure(처리구)와 composted cow manure(무처리구)에서 각각 순수 분리한 미생물의 exo- 및 endo-cellular phytase의 활성을 측정하고 처리구와 무처리구 간의 인의 함량을 비교함으로써 지렁이가 우분 내 인산가수분해효소의 활성과인의 함량에 미치는 영향을 검토하였다. 1. 미생물의 exo-cellular phytase의 활성은 EW-3,9, CT-2,4,5, SO-2,3,5 등에서만 확인되었으며 지렁이, 처리구와 무처리구 간에는 비슷한 활성을 보였으나 가장 높은 활성을 나타난 균주는 지렁이 분리한 EW-3이었다. 2. 미생물의 endo-cellular phytase의 활성은 모든 균주에서 확인되었고 지렁이와 처리구에서 분리한 균주의 효소활성이 무처리구에 비해 비교적 높은 경향을 보였으며 가장 높은 활성을 나타낸 균주는 처리구에서 분리한 CT-3이었다. 3. 가장 높은 phytase 활성을 나타낸 EW-3과 CT-3균주는 각각 Microbacterium sp.와 Corynebacterium sp.인 것으로 확인되었다. Vermicomposted cow manure의 총 인과유효인의 함량은 composted cow manure에서 보다 약 41.0%, 36.4% 정도 각각 감소하였다. The effect of earthworm on the recycling or control of organic P in environment has been investigated. The activity of phytase(myo-inositol hexaposphate phosphohydrolase, EC 3.1.3.8) produced by isolated microoganisms from vermicomposted cow manure was usually higher than that of phytase produced by isolated microorganisms from composted cow manure. However the activity of phytase excreted by seperated earthworm(Eisenia foetida) was not detected. The concentration of total P and available P was revealed 2.88%, 0.22% in composted cow manure and 1.70% 0.14% in vermicomposted cow manure.

This experiments was carried out to evaluate the potential winter hardiness of tall fescue varieties based on the data of dry weight of plant per relative tiller appearance rates(DW/RTAR) in mountainous pastures of Taekwalyon area. The results obtained were as follows; I . The varieties were classified into 2 groups by dry weight of plant per relative tiller appearance rates (DWIRTAR). Thus, Forager and Fuego belong to the group with more than 2.0 in DW/RTAR but Barcel. Barvetia. Demeter, Enforcer, Johnstone. Safe and Stef belong to the group with less than 2.0 in DW/RTAR respectively. 2. The dry weight of plant per relative tiller appearance rates(DM/RTAR) and dry weight of plant(DW) of 1st cutting were significantly positive corrclated with number of heading tillers and dry weight of heading tillers. 3. The dry weight of plant per relative tiller appearance rates(DW/RTAR) was significantly positive correlated with dry weight of plant(DW) of final cutting and of 1st cutting. 4. The varieties with high DW/RTAR showed a high dry weight of plant(DW) of 1st cutting. Accordingly, it was concluded that DW/RTAR is a valuable character for evaluating potential winter hardiness of tall fescue on mountainous pastures of Taekwalyon area.
