摘　　要：为明确甘肃省定西市临洮县百合不同生长期田间主要杂草种类及危害特点,本研究采用“W”形5点取样法,对百合3个主要生长期田间主要杂草种类进行调查并对其危害进行分析。调查发现临洮县百合田有14科31种杂草,其中在百合生长早期、中期、后期危害最严重的杂草均为打碗花、藜、苦苣菜、狗尾草,分别属于旋花科、藜科、菊科、禾本科杂草,这4种杂草在百合3个生长期的重要值均最高,分别在10.1%、15.0%、11.6%和8.9%以上。掌握临洮县百合田杂草的发生种类及优势杂草,为今后百合田杂草防除提供了可靠依据。To identify the main weed species and their hazard characteristics during the different growth periods of lily in Lintao County,Dingxi City,we conducted a survey using the five-point sampling method and then analyzed the main weed species in the field during the three main growth periods of lily.The investigation found that there were 31 species of weeds from 14 families in Lanzhou lily plantation base in Lintao,among which Calystegia hederacea Wall.of Convolvulaceae,Chenopodium album L.of Chenopodiaceae,Sonchus oleraceus L.of Asteraceae,and Setaria viridis Beauv.of Gramineae were the most harmful weeds in the seedling,growth,and later stage of Lilium davidii.The important values of these four weeds were the highest in the three growth periods of lily,which were above 10.12%,15.06%,11.63%,and 8.92%,respectively.The species of weeds in Lintao were complex and diverse.Understanding the occurrence types and dominant weeds in lily fields in Lintao provides a reliable basis for weed control in lily fields in the future.
