Abstract

This study was conducted to develop the homemade soil media adequate to raising rice seedlings for machine transplanting. A raising experiment of rice seedlings was tested on a newly developed soil medium made mainly from briquette ash compared to ones of infertile red earth and fertile paddy loams. Dry weight of rice seedlings at 36 days after seeding was slighly lower in the plot of briquette ash that in soils, however, it was quite good in the plot of briquette ash mixed with zeolite and diatomaceous earth. pH in soil media was high in briquette ash and also high in soils mixed compost compared with out compost treatment, resulting in higher occurrence of damping off or physiological disorder. Good rice seedlings could be raised in soil media without compost and briquette ash mixed with zeolite diatomaceous earth.

수도육묘용(水稻育苗用) 상토(床土)의 자가제조이용(自家製造利用)을 목적(目的)으로 상토개발(床土開發)을 연탄재를 활용(活用)하여 수행(遂行)하였으며 일반(一般) 논양토(壤土) 및 산양토(壤土)를 대조(對照)로 하여 육묘시험(育苗試驗)을 한 결과(結果) 연탄재 단독(單獨)에서는 건물중(乾物重)이 다소 떨어졌으나 연탄재+제오라이트, 연탄재+규조토(硅藻土)에서는 대조(對照)와 대등(對等)하였다. 한편 상토(床土)의 pH는 연탄재단독(單獨)과 토양(土壤)에 퇴비(堆肥)를 혼합(混合)한 상토(床土)에서 높아 립고병(立枯病)이 발병(發病)되었다. 토양(土壤)에 퇴비(堆肥)를 혼합(混合)하지 않고도 양묘(良苗)의 육성(育成)이 가능(可能)하였으며 특(特)히 연탄재를 이용(利用)하여 제조(製造)한 상토(床土)에서도 양묘(良苗)의 육성(育成)이 가능(可能)하였다.
