전.후작물 도입에 의한 중부지역 들깨 작부체계에 관한 연구

Abstract

To increase self-sufficiency ratio and agricultural income, six cropping systems by introducing several crops in perilla were tested from 2001 and 2002. Weed occurrence was high in barley+perilla and safflower+perilla cropping system. Pre-and post-crops in barley+perilla and safflower+perilla showed good growth. Safflower+perilla cropping system was labor-saying and cost down because polyethylene film of pre-crop was reused in post-crop. But when perilla was introduced as post-crop of sesame, delayed seed date resulted in decreased growth and grain yield. The income in barley+perilla and safflower+perilla was greater 4.1fold and 5.2fold, respectively than in perilla mono-crop system. Soil physical properties were improved in order of safflower+perilla, barley+perilla cropping system.

몇가지 전$.$ 후작물을 도입하여 들깨에 관한 작부체계 확립으로 안정생산 기반을 구축하고자, 들깨단작 등 6작부유형을 도입하여 2001년부터 2002년까지 2년에 걸쳐 시험한 결과 잡초발생은 보리+들깨, 흥화+들깨에서 많았다 보리+들깨와 홍화+들깨의 작부유형은 전$.$후작물의 생육에 지장이 없으며, 홍화+들깨는 전작물의 비닐 피복물을 후작물에서도 이용할 수 있어 생력화와 경영비를 절감할 수 있었으나, 참깨가 전작물로 도입 시에는 파종기가 늦어 생육이 부진하고 수량이 감소되었다. 소득은 들깨단작에 비하여 보리+들깨와 홍화+들깨에서 각각 4.1배, 5.2배 높았다. 작부유형별 토양 물리성 개선효과는 보리+들깨와 홍화+들깨에서 양호하였다.
