Abstract

This study was conducted to evaluate the effects of microbial and conventional chemical fertilizers on the growth of the radish(Raphanus sativus L.) and Chinese cabbage(Brassica campestris L.). Chemical fertilizer, microbial fertilizer, and combined one of them were applied after transplantation. Subsequently, microbial fertilizer was applied every 3 days. At 5 weeks after transplantation, plants were harvested for measurement of weight and length of the aboveground and underground parts. Fresh weight of the underground part in radish was greater in the combined application of chemical and microbial fertilizer (148.9g) than those of the chemical fertilizer(112.8g) or the microbial fertilizer(143.6g). Application of microbial fertilizer(160.3g) was more effective than that of chemical fertilizer(111.1g) on fresh weight of the aboveground part in radish. Fresh weight of the aboveground part in Chinese cabbage was greater in the combined application of chemical and microbial fertilizer(316.6g) than those of chemical fertilizer(225.7g) or microbial fertilizer(232.5g). Application of microbial fertilizer($2735.9cm^2$) was more effective than that of the chemical fertilizer($2387.5cm^2$) on the leaf area in Chinese cabbage. However, the largest increase in plant growth was found using the combined application of the chemical and microbial fertilizer. These data suggest that microbial fertilizer can be used to replace conventional chemical fertilizer as an eco-friendly fertilizer. Furthermore, the combined application of the chemical and microbial fertilizer greatly improves the growth of radish plants. These results suggest a new fertilization method to produce vigorous breeding materials in radish and Chinese cabbage.

미생물제제 및 화학비료 시비에 따른 무와 배추의 생육 변화를 조사하기 위해 지상부와 지하부의 길이, 엽면적, 그리고 중량을 측정하였다. 시비 종류에 따른 무의 지하부 생체중은 미생물제제와 화학비료의 혼합 시비에서 148.9g으로 가장 높아 화학비료 처리구(112.8g)와 비교하여 약 1.3배 증가하였으며, 지상부의 생체중 역시 미생물제제와 화학비료의 혼합 시비 처리구(160.3g)에서 화학비료 처리구(111.1g)와 비교해 약 1.4배 증가하였다. 미생물제제와 화학비료를 혼합하여 처리하였을 때 생육이 가장 왕성하였으나 미생물제제 처리구도 화학비료 단독시비 처리구의 생육과 비교하여 지상부, 지하부 모두 생체중이 증가하는 것을 확인할 수 있었다. 배추의 지상부 생체중은 미생물제제와 화학비료의 혼합시비 처리구에서 316.6g으로 가장 높아 화학비료 처리구(225.7g)와 비교하여 1.4배 증가하였으며, 또한 지하부의 생체중도 미생물제제와 화학비료의 혼합시비 처리구(4.4g)에서 화학비료 처리구(3.1g)와 비교하여 1.4배 증가하였다. 배추의 엽면적은 미생물제제와 화학비료의 혼합시비 처리구, 화학비료 처리구, 미생물제제 처리구에서 각각 3567.7, 2387.5, $2735.9cm^2$로 미생물제제의 처리로 배추의 엽면적이 증가함을 확인할 수 있었다. 실험의 결과를 통해 미생물제제가 관행의 농법에서 사용되는 화학비료를 대체하여 친환경비료로 사용될 수 있을 것으로 판단된다. 또한 화학비료에 토양미생물제제를 혼용 처리하여 무와 배추의 생육을 크게 향상시킬 수 있을 뿐 아니라 건전한 육종재료를 육성하기 위한 시비 방법으로 이용될 수 있을 것으로 판단된다.
