고추에 대한 맥주오니(麥酒汚泥) 시용효과시험(施用效果試驗)(제(第)I보(報))

Effect of Beer Sewage Sludge Application on Red Pepper

토양비옥도(土壤肥沃度)가 보통(普通)인 사양토양(砂壤土壤)에서 맥주오니(麥酒汚泥)를 새로나고추에 시용(施用)하여 생육(生育)과 수량(收量) 및 토양(土壤)의 화학적성질(化學的性質)에 미치는 영향(影響)을 밝히고져 포장시험(圃場試驗)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 고추의 초기생육(初期生育)은 한발(旱魃)로 인(因)하여 오니처리구(汚泥處理區)가 극(極)히 불량(不良)하였으나 후기(後期)에는 수분공급(水分供給)으로 엽색(葉色)이 푸르고 초세(草勢)가 양호(良好)하여 초장(草長) 절간수(節間數) 및 주간고(主幹高)에서 표준구(標準區)와 큰 차이(差異)는 없었다. 2. 주당숙과수량(株當熟果收量)은 NPK와 PK+, 오니(汚泥)1200Kg, 2400Kg, 및 4800Kg구(區)가 표준구(標準區)에 비(比)하여 각각(各各) 약간(若干) 적었다. 3. 건과율(乾果率)은 NPK+, PK+오니(汚泥)1200kg 2400Kg 및 4800Kg구(區)가 표준구(標準區)에 비(比)하여 다소(多少) 높은 경향(傾向)이었다. 4. 오니(汚泥)1200Kg/10a(N=51Kg상당(相當))시용(施用)은 유기질비료(有機質肥料)로서의 비효(肥效)는 충분(充分)히 인정(認定)되었으나 시용량(施用量)의 과다(過多)로 생육조해현상(生育阻害現象)을 보였다. 5. 오니시용(汚泥施用)은 토양(土壤)의 pH를 낮게하고 토양중(土壤中)의 유기물함량(有機物含量)과 치환성염기(置換性鹽基)등을 다소(多少) 증가(增加)시켰다.

A filed experiment was carried out to investigate the effects for growth, yield of red lopper (Saelona) and properties of soil by beer sewage sludge application to the sandy loam which fertility was common. The results obtained were summerized as follows. 1. Growth of red pepper in sludge plot was very poor by drought in early stage, but color of loaves was green and growth strength was better than nontreated plot after rainfall in last stage. There were no significant differencies between plant height, number of branch on main stem and stem height in sludge and standard plot. 2. Yield of matured red pepper per plant in NPK+, and PK+ sludge 1200kg, 2400kg and 4800kg/10a plot were less than those in standard plot respectively. 3. Ratio of dry weight of matured red pepper in NPK+, and PK+ sludge 1200kg, 2400kg and 4800kg/10a were high than those in standard plot appreciably. 4. Sewage sludge application (1200kg/10a. N=51kg) was available as nitrogen source of organic fertilizer considerably, but there were some growth inhibition by excess of amount applied. 5. Sewage sludge application decreased the pH of the soil and increased the content of organic matter and exchangeable babe in the soil appreciably.
