Poduction of Organic Compost to Exclusive use in a Ginseng

인삼 전용 유기질 퇴비제조 및 시용효과

In order to the development of a new organic compost to exclusive use in a ginseng, we conducted the study of the preparation of organic fertilizer and the application effect of organic fertilizer in cultivation of ginseng. The new organic compost was composed of dryed broad leaves of acorn 40%, puffed husks of rice 40% and organic material mixture 20%. The chemical properties of the organic compost shown that the values of the total nitrogen, available phosphate, pottasium, calcium, magnesium, organic matter and C/N ratio were $17g\;kg^{-1}$, $8g\;kg^{-1}$, $11g\;kg^{-1}$, $14g\;kg^{-1}$, $4g\;kg^{-1}$, $794g\;kg^{-1}$, and 26.7, respectivly. The application effect of organic compost in the cultivation of ginseng shown that survival ratio of above ground plant of ginseng was shown the high value than control, and the ratio of root rot and red colored root were decreased. The optimal amount of organic fertilizer for ginseng seedling was $24M/T\;ha^{-1}$. The chemical properties of the ferilized soil were analyzed.
