작약 비가림 재배시 생육 특성과 수량에 미치는 영향을 구명하기 위해 시험을 수행한 결과는 아래와 같다. 비가림 재배시 노지 재배에 비해 맹아기와 개화기가 각각 9일, 15일빨랐으며 경장, 경수 등도 더 크거나 많았다. 병발생은 녹병, 탄저병, 횐가루병, 뿌리썩음병은 비가림 재배가 노지 재배에 비해 현저히 감소 되었으나 점무늬병은 비슷하였다. 근장, 근수, 근경은 비가림 재배가 노지 재배에 비해 생육이 양호하였으며 뿌리 수량도 비가림 재배가 10a당 2,395kg으로서 노지 재배의 2,201kg, 1,892kg에 비해 27%, 9% 증수 되었다. 품질면에서 뿌리 색도는 비가림 재배가 노지 재배에 비해 더 양호하였으며 상품 수량도 향상되었다.
This experiment was carried out to investigate the effect of rain shelter cultivation on growth characteristic and yield on Paeonia lactiflora Pallas. The sprouting time and flowering time of rain shelter cultivation were 9days and 15days, more quickly than that of field conditions, and stem length and number of stem per plant were many more or larger. The disease occurrence rain shelter cultivation was decreased of rust, anthracnose, powdery mildew and root rot disease compared to field conditions, and leaf spot disease was to similar. The root length, number of root and root diameter were to be good in the rain shelter cultivation. Root color and commercial ratio of rain shelter cultivation were better lighten and improved than field cultivation. Root yield of rain shelter was 2,395kg/10a, this was increased 9% and 27% respectively, compared to 2,201kg/10a, 1,892kg/10a of field A and field B.
