Abstract:

Taking‘ Anqiudajiang’ as experimental material，this paper studies the effects of 5
bactericides spread on different ginger growth periods on controlling ginger bacterial wilt. The results indicated
that no remarkable influence on ginger seedling sprouting rate after soaking mother ginger in the bactericides
of Jiangwenjing AS（ astragalus polysaccharide，berberine，alkannin≥2.8%），45% Amobam AS，72%
streptomycin sulfate SP，3% Kejunkang WP，20% Saisentong SC before sowing. It is good for controlling ginger
bacterial wilt after using these 5 bactericides. The control effect of Jiangwenjing AS is the best reaching 92.6%，
and that of 3% Kejunkang WP takes the second place，reaching 90.5%. The income of using Jiangwenjing AS is
the highest，compared with the other treatments. It can reach 350，229 RMB·hm^-2.

摘要：

以安丘大姜为试材，研究在生姜不同生长期施用5 种药剂对姜瘟病的防治效果。试验结果表明，生姜播种前用姜瘟
净水剂（黄芪多糖、小檗碱、紫草素≥ 2.8%）500 倍液、45% 代森铵水剂600 倍液、72% 农用硫酸链霉素可溶粉5 000 倍液、
3% 克菌康可湿性粉剂600 倍液、20% 噻菌铜悬浮剂500 倍液浸种，对生姜出苗率没有显著影响。浸种后在生姜出苗、三股杈、
大培土时用上述药剂进行灌根处理，对降低姜瘟病发病率均有效果，其中以姜瘟净水剂防治效果较好，达92.6%；3% 克菌
康可湿性粉剂次之，为90.5%。除去用药成本，生姜收益以姜瘟净最高，每667 m² 为23 348.6 元。
