Abstract
The experiment was conducted to find causes of rooting failure in divided crown of peony cultivation. The results were as follows : In farmer s fields, damage rate of rooting failure in divided crown of peony was 32% as non-sprouting 5.6%, withering after sprouting 20.7%, and wilting after sprouting 5.7%, repectively. Damage degree in farmer s fields was followed, above 70% by 4%, 41 to 70% by 17%, 11 to 40% by 45% per total field area, respectively. It was caused by rooting failure. Damage rate of rooting failure as affected by different planting time was 18.2% for planting in autumn, 42.9% for planting in spring, and damage in divided crown was higher than in seedling. As periods to planting were prolonged, growth and yield were larger poorly, treatment with seminal-root sterilization and soil insecticide showed good growth and rooting but untreated control was very poor. Main cause of rooting failure in divided crown of peony was disease, Cylindrocarpon sp. and low quality of seeds.
작약(芍藥) 분주묘(分株苗)의 활착불량(活着不良) 실태(實態)와 원인(原因)을 구명하기 위하여 시험 연구한 결과는 다음과 같다. 1. 작약 분주묘의 농가 포장 활착 실태 조사 결과 활착불량 피해율은 32%에 이르고 외형적 피해 실태는 무출현(無出現) 5.6%, 출현후(出現後) 고사(桔死) 20.7%, 출현후(出現後) 위조가 5.7%였다. 2. 활착불량 피해 정도별 농가 실태는 71%이상 피해를 본 필지가 4%,
