초록

헤어리베치를 배 과수원에서 녹비 및 피복작물로 재배하여 효과적이고 환경친화적인 과수원 관리 기술을 개발하기 위하여 시험을 실시하였다. 월동직후 헤어리베치의 지상부 건물중은 5월 하순까지 급격히 증가하였으며, 지표면이 신속하게 피복되고 성숙 고사된 후에도 잔유물이 토양에 피복됨으로서 잡초발생 억제 효과가 좋았다. 단위면적당(ha) 파종량은 70kg 정도가 적합하였으며, 1회 파종으로 3년정도 과수원 초생관리가 유지되었다. 헤어리베치의 지상부 질소 함량은 5월 초․중순에 가장 높았으며, 헤어리베치 재배후 과수원 토양을 분석한 결과 토양산도, 유기물함량, CEC, 토양 무기성분 함량이 증가되었다.

영어초록

Hairy vetch (Vicia villosa) as a legume crop was seeded 30kg, 50kg, 70kg, 90kg per ha at early September 2003 in pear orchard. The experiments of common hairy vetch were for examine the sod culture and manure effect in orchard. After wintering in early March hairy vetch with high cold tolerance showed rapid regrowth compared to other plants and the dry weight was maximized at flowering period on late May to early June. Weed control was effective highly due to hairy vetch residues after withering in summer season. The practical seeding rate per ha was 70kg for covering soil and weed control, and the sod culture by hairy vetch when is seeded one time at mid summer was maintained for 3 to 4 years. N content of aerial part of hairy vetch reached the maximum at flowering stage in late May to early June. After 4 years of sod culture of hairy vetch in orchard soil pH was changed from 5.4 in no-treatment to 5.9 in 70kg plot and CEC, organic
matter content and mineral nutrition were increased more than in no-treatment plot significantly.
