Abstract
This study was desinged to find out the effects of soil physical properties on root development of barley. Barley fields were selected in consideration of drainage class and texture. Soil hardness were measured at the field. Soil bulk density, air ratio and root distribution were obtained from the core samples. 1. The amount of roots were increased and the root were distributed deeper layers with better drainage class and finer soil texture. 2. Soil hardness was related to soil bulk density, and the regression coefficient was increased with clay content (Clay ;
토양의 물리적(物理的) 특성(特性)이 작물(作物)의 뿌리 발달에 미치는 영향(影響)을 구명(究明)하기 위하여 배수등급(排水等級), 토성조건(土性條件)이 상이(相異)한 대맥포장에서 토양물리성과 층위별(層位別) 뿌리 분포(分布)를 조사(調査)한 결과(結果)는 다음과 같다. 1. 배수(排水)가 양호(良好)할수록 총뿌리량은 증가(增加)되고 깊게 분포(分布)하였으며 동일(同一)한 배수등급(排水等級)에서는 토양이 세립질(細粒質)일수록 총뿌리량이 많은 경향(傾向)이었다. 2. 토양의 경도(硬度)는 가비중과 밀접(密接)한 관계가 있었으며 토성(土性)이 세립질(細粒質)일수록 유의성(有意性)이 높았다. < 식토(埴土) (
