摘要:
<正>在自行研制的人工气候室内,以日本无刺槐木(Aralia elata var. inermis)休眠枝条离体茎段为试验材料进行了水培人工促成产芽实验。结果表明:不同的茎段长度处理,以20cm茎段产芽最好,差异极显著;不同的遮光处理,以遮光处理为好,但差异不明显;不同的营养条件处理,以50mL水+50mL全成分营养液处理最佳,但与100mL全成分营养液无显著差异;不同的直径茎段处理,以最粗直径(平均直径12.3mm)最佳,与最细直径之间差异极显著;不同的树龄相同直径处理,以2年生的产芽量最大,但差异不显著;同一茎段不同的芽位处理,以两侧芽产芽较好,但无显著性差异。
Abstract:
The root rot disease of peony is one of the serious diseases. Average infected individual plant rates in old and’ new peony garden were up to 35% and about 20% respectively in the cultivation region in Heze, Shandong Province. According to the culturing characters and morphological properties of 137 isolates came from 64 infected root samples among 9 batches after selecting, purifying, re-inoculating testing, the pathogenic fungi of peony root rot disease was finally identified as the Fusariurn solani. Overwinter of pathogen mainly depended on mycelia and conidia in the root, the disease was prevalent from May to July. The occurrence of disease had a close relation with those factors including layer stubble and soil acidity and alkalinity. The Ltiheng 1,Ltiheng 2 and 50% Duofu were proved to be the effective fungicides for controlling peony root rot by laboratory toxigenicity testing and field fungicides efficacy. The control effect in new and old peony garden was about 90% and 80% respectively while the disease indices of them were controlled about 5 and 10 respectively, by applying 4 times from middle March, the pre-leafing date of peony through middle July. The paper provides a profound and systematic study on the peony root rot disease and will help to promote the development of industrialization of the peony.
