作者于1986-1989年连续4年在砀山果园场对芦笋茎枯病Phoma asparagi Sacc的发生规律及防治进行了研究.提出上年越冬病残体是当年茎枯病的主要初侵染源,采笋田在停采后10天左右即6月上、中旬开始发病,6月中旬至7月中、下旬为病害流行初盛期,7月下旬至9月中、下旬为病害流行盛期.降雨是茎枯病的主要影响因子,6-9月间降雨量与同期发病率或病情指数呈明显正相关.通过药剂防治使翌年芦笋产量增加50%以上,并总结出芦笋茎枯病综合防治技术要点.
The author studied the regularity and control of Phoma asparagi Sacc in Asparagus officinalis field in Qianshan orchards for four consecutive years from 1986 to 1989. It was suggested that the overwintering venereal disease in the previous year was the main source of initial infection of stem blight Shuda in about 10 days after the stop mining that is, the onset of disease in mid-June, mid-June to mid-July, late for the disease early epidemic, late July to mid September, late for the peak epidemic. Is the main influencing factor of stem blight, and the rainfall between June and September has a positive correlation with the incidence or disease index of the same period.The production of asparagus increased by more than 50% in the following year by means of chemical control, and the comprehensive prevention and control technology of asparagus stem blight Point.
