This study was conducted to investigate the effect of different concentrations of microbial products on growth of chinese cabbage and microorganisms in soil. Two different levels of microbial products, such as 50 times and 100 times diluted solutions of chitosan, wood vinegar and EM activity liquid, were treated for foliar application. The results were summarized as follows : Among foliar applications of microbial products, 100 times diluted solution of chitosan was effective on growth of chinese cabbage comparing to other levels of dilutions and untreated control plot. The number of microorganism in the soil tended to increase under the treatment of microbial products compared to control plot. Especially, the numbers of the bacteria and actinomycetes were estimated 73.67×103 CFU/g and 34.00×103 CFU/g, respectively, under the treatment of 100 times diluted solution of chitosan. 본 시험은 배추로 하였고, 미생물제제인 키토산, 목초액 및 EM 활성액을 처리하여 2003년 9월부터 동년 12월까지 동아대학교 부속농장의 시설 하우스내에서 미생물제제의 처리농도에 따른 효과를 검정하기 위하여 실시한 결과는 다음과 같다. 미생물제제 처리에 따른 배추의 생육은 전반적으로 무처리구인 대조구에 비해 미생물제제 처리구에서 비교적 양호하였으며, 미생물제제간에는 키토산 처리구에서 다소 양호하였다. 특히 키토산 100배액 처리구에서 배추의 엽장 및 주중이 각각 32.96㎝ 및 5.60㎏으로 다른 처리구에 비해 양호하였다. 토양 미생물상 변화는 무처리구에 비해 미생물제제 처리구에서 다소 증가하는 경향을 보였고, 특히 키토산 100배액 처리구에서 세균 및 방선균수가 각각 73.67×103 CFU/g 및 34.00×103 CFU/g로 다른 처리구에 비해 증가한 경향을 보였다.

This study was conducted to investigate the effect of microbial product on microorganisms in soil and the growth of leaf lettuce. The test material were treated with chitosan, wood vinegar and EM activity liquid, and treatment concentration was 50 times solution and 100 times solution level with foliar application. The results were summarized as follows : Among foliar application of microorganisms treatments diluted by chitosan 100 times solution level was effective considering growth of leaf lettuce as compared other dilutions and control plot. Change of microorganism number in the soil for cultivation of chinese cabbages and leaf lettuce was increased with microorganism treatment plot as compared with control plot. Specially chitosan 100 times solution level showes the most significant effect. 본 시험은 공시작물을 잎 상추로 하여, 키토산, 목초액 및 EM 활성액을 각각 처리하여 2003년 3월부터 동년 5월 30일까지 동아대학교 생명자원과학대학 옥상 플라스틱 하우스 내에서 Pot시험을 실시한 결과는 다음과 같다. 키토산, 목초액 및 EM 활성액 처리에 따른 잎 상추의 생육은 전반적으로 무처리구인 대조구에 비해 비교적 생육이 양호하였으며, 처리간에는 키토산 처리구에서 다소 양호하였다. 특히 키토산 100배액 처리구에서 잎 상추의 엽면적 및 생체중이 각각 337.85㎠ 및 53.79g으로 다른 처리구에 비해 높게 나타났다. 키토산, 목초액 및 EM 활성액 처리에 따른 잎 상추내 엽록소함량의 경시적 변화는 생육기간이 길수록 엽록소함량이 증가한 경향을 보였고, 처리간에는 키토산 100배액 처리구에서 다소 엽록소함량이 많은 것으로 나타났으나 큰 차이는 없었다. 토양 미생물상 변화는 무처리구에 비해 키토산, 목초액 및 EM 활성액 처리구에서 다소 증가하는 경향을 보였고, 특히 키토산 100배액 처리구에서 세균수가 46.33×103 CFU/g로 다른 처리구에 비해 증가한 경향을 보였다.

A research was conducted to investigate the effect of treatment of woody charred materials such as wood vinegar, charcoal, and mixture of wood vinegar and charcoal on the growth and components of tomato and chinese cabbage. The effect of treatment of woody charred materials on the growth and components of tomato the research findings are as follows. The total number of soil microorganisms increased in the groups treated with woody charred materials compared with the control. The fruit number, fruit length, fruit diameter, fruit weight, hardness and sugar contents of tomato did not show significant difference in all plots treated with woody charred materials, but the plot treated with wood vinegar + charcoal showed relatively higher values in general. Vitamin C contents were shown higher in the plots treated with woody charred materials than the control, and among the treatment plots. The effect of treatment of woody charred materials on the growth and components of chinese cabbage the research findings are as follows. The soil chemical components did not change before and after the treaiment of woody charred materials. The total number of soil microorganisms increased in the treatment plots compared with the control, The leaf length, leaf width, inner leaf number, plant weight, and head weight of Chinese cabbage treated with woody charred materials were in general larger than the comtrol. Among the treatment plots, the plot treated with wood vinegar + charcoal showed slightly higher values. The contents of minerals in chinese cabbage such as Ca, Fe, K, Mg and Mn were higher in the treatment plots than the control.

For this study, Smilex powder, a pesticide, was sprayed on the Altari radish, and then underground water, Chitosan solution (×500), and wood vinegar solution (×1000) were evenly sprayed on the Altari radish respectively. Samples of Altari radishs for residual pesticide analysis were taken two hours, 1 day, 7 days, and 15 days after treatments, and the detectable concentration and degradability of procymidone, the pesticide residue, were measured. The results obtained are as follows: 1. When detectable concentration of procymidone within the altari radish was measured, treatment plots sprayed with underground water, Chitosan solution (×500), and wood vinegar solution (×1000) were found to show lower detectable concentration than the non-treatment plot which was sprayed with pesticide only. Especially, the treatment plots sprayed with Chitosan solution (×500), and with wood vinegar solution (×1,000) showed lower values than the average. 2. When the degradability of procymidone within the Altari radish was measured, the plot treated with Chitosan solution (×500) and the plot treated with wood vinegar solution (×1,000) were found to have relatively higher degradability of procymidone. There were not much differences among testing materials in the degradability of residual pesticides. However, the plot treated with Chitosan solution (×500) showed higher degradability. In terms of average degradability with time, degradability increased sharply 7 days after the foliar application of testing materials. 3. When the daily far-sighted view survey was conducted in order to find out growth disorder and damage on the Altari radish plants by the treatment of underground water, Chitosan solution (×500), and wood vinegar solution (×1,000), no symptomatic physiological disorders was observed on all the plants tested during the whole growing season at the tested concentration level.

From the experiments on the effect of chitosan and wood vinegar, which are environment-friendly materials, on the growth of eggplant and leaf lettuce, the following results were obtained. 1. The effect of chitosan and wood vinegar treatment on the growth of eggplant 1) There was no difference in soil component elements before and after treatment with chitosan and wood vinegar. The total number of microorganisms tended to increase after treatment with chitosan and wood vinegar, while the number of bacteria increased among microorganisms. However, there was no consistent tendency in the number of Acinomycetes, fungi, and trichodema between treatments. 2) The growth and the yield of eggplant increased compared with the control plot in both the chitosan-treated plot and the wood vinegar-treated plot. However, there was no significant difference between the treatments. The yield of eggplant per 10a increased in chitosan- and wood vinegar-treated plots compared with the controlled plot. There was no significant difference in treatments, however, the plot treated with 800 times-diluted solution showed a higher growth. 2. The effect of chitosan and wood vinegar treatment on the growth of leaf lettuce 1) There was no difference in soil component elements before and after treatment with chitosan and wood vinegar. The number of bacteria increased among microorganisms. However, there was no consistent tendency in the number of Acinomycetes, fungi, and trichodema between treatments. 2) The growth of leaf lettuce in both chitosan-treated plot and wood vinegartreated plot increased compared with the control plot, however, there was no significant difference between the treatments. On the whole, the plot treated with greater concentration showed a higher growth.
