초록
본(本) 연구(硏究)는 무저(無底) lysimeter내에서 참깨의 멀칭재배에 따른 물소모량변화를 산출하고자 농업기술연구소 토양 물리과 관개시험포장(灌槪試驗圃場)에서 1991년과 1992년에 중부지방(中部地方)의 표준파종기(標準播種期)인 5월(月) 10일(日)에 파종(播種)하여 참깨품종 "안산깨"를 시험재배(試驗栽培)하였다. 토양(土壤)은 배수(排水)가 다소 양호(良好)한 본량(本良) 사양토(砂壤土)였다. 그 결과(結果)는 다음과 같이 요약(要約)된다. 1. 물소모량(消耗量)은
Determining the actual evapotranspiration(ETa) of a crop, and appropriate water management of the crop based on the ETa are very important For increasing the yield. The present study aimed at determining ETa and crop coefficient of sesame growing under different climatic conditions with the transparent thin polyethylene film mulch(0.03 mm thick) and without this mulch. Bottomless cylindrical lysimeters(105cm in diameter, 120cm in height, protruded 20 cm above the soil surface) were installed on the field of sandy loam "Bonyang series" soil with a moderate drainage. The determination of ETa was performed by measuring each component of a model equation,
