본 연구에서는 지렁이의 분립과 토양의 혼합비율이 Orchardgrass 유식물체의 생육에 미치는 영향조사함으로서 생육에 적합한 혼합비율을 추정하였다. 지렁이의 분립과 토양의 혼합비율은 100: 0, 80:20, 60: 40, 40: 60, 20: 80, 0: 100으로 하였다. 분립 60%의 혼합구에서 지상부와 뿌리의 건물중 및 생물학적 수량이 다른 혼합구보다 많아서 Orchardgrass 유식물체의 생육에 가장 적합한 흔합비율로 추정되었다. 이때 토양조건은 pH 6.16, 유기물함량 13.84%, 전질소량 0.84%, 유효인산함량 1413.9 ppm,양분보전능 me/100g 이였다. 생물학적 수량은 지상부와 뿌리의 건물중과 개체당 경수 및 1경중과 유의한 정상관이 존재하였다.

This experiment was carried out to determine the effect of mixture ratios of worm cast and soil on the growth orchardgrass seedlings, and estimate the adequate mixture ratio of worm cast for plant growth media. Mixture ratios of worm cast and soil were 100:0, 80:20, 60:40, 40:60, 20:80 and 0: 100, respectively. The resu1ts were summarized as follows; 1. The value of dry weight of shoot(SW), dry weight of root(RW), number of tillers per plant(NT) and biological yield(BY) were the highest in the mixture with 60% of worm cast. Particularly, the dry weight distribution to root in 20%-60% mixture ratios of worm cast were higher than those grown in 80%-100% mixture ratios of worm cast, it may due to the enhancement of root growth by adquate worm cast mix. 2. The orchardgrass seedlings in the 60% mixture ratio of worm cast grown in favourable soil conditions compared to those grown in other mixtrure ratios of worm cast and soil without worm cast. The soil analysis data showed that 60% mixture ratio of worm cast contained pH 6.16, 13.84% of organic matter, 0.84% of total nitrogen, 1,413.9ppm of available phosphorus and 16.7me/100g of cation exchange capacity, respectively. 3. Biological yield(BY) indicated positive significant correlation with the dry weights of shoot(SW) and root(RW). And, the dry weight of shoot(SW) had positive correlation with the number of tiller per plant(NT) and dry weight of tiller(WT).
