作者1987—1989年对芦笋茎枯病Phoma asparagi Sacc的发生规律及防治技术进行研究,提出济南地区无论在地表或土内的病株残体上,该病病菌均能越冬成活。未采笋田发病始期为5月18—25日,流行初盛期在7月中、下旬;采笋田一般在放笋后10天左右查到病株,流行初盛期在7月底到8月上、中旬,盛期在8月中、下旬至9月上旬。发病与降雨关系密切,5—8月降雨日数与同期病情指数呈明显正相关,在试验的基础上制定了“芦笋茎枯病综合防治技术规范”,经大面积推广,使济南地区的芦笋实际总产量由1987年的275万公斤上升到1989年的425万公斤。
The author studied the occurrence regularity and control technology of Phoma asparagi Sacc in Asparagus stem blight from 1987 to 1989, and proposed that the pathogen could survive in winter in either the surface or the soil in Jinan. Undead bamboo field incidence of May 18-25, the prevalence of early July in mid-late; mining bamboo shoots are generally found in about 10 days after the shooting of diseased plants, the prevalence of early July to the end of 8 On the moon, mid, peak in mid-August, late to early September. There was a close relationship between the incidence and rainfall. The number of rainy days in May-August was positively correlated with the disease index in the same period. On the basis of the experiment, the “Technical Code for Comprehensive Prevention and Control of Asparagus stem Blight” was formulated. After large-scale popularization, the actual asparagus in Jinan The total output rose from 2.75 million kg in 1987 to 4.25 million kg in 1989.
