摘要
田野菟丝子Cuscuta campestris Yuncker是一种有潜力的可用于生物防治的全寄生植物。为了解田野菟丝子防治薇甘菊Mikania micrantha H.B.K的效果和安全性,在深圳7个森林公园的1 218hm2薇甘菊危害区投放田野菟丝子并开展野外监测,结果发现:发生危害的薇甘菊面积平均为792hm2(盖度为53%～73%),投放田野菟丝子后,其寄生率为44%～87%,薇甘菊面积减少了426hm2左右,盖度下降了21%～53%;受田野菟丝子影响的其他植物有153种,隶属43科109属,其中田野菟丝子接触微甘菊但不产生影响(0级)的植物15种,接触薇甘菊且对其他植物造成影响(Ⅰ～Ⅲ级)的植物有138种,除薇甘菊以外未发现致死种。此结果为大面积使用田野菟丝子防治薇甘菊的可推广性提供了理论与实践依据。
Cuscuta campestris Yuncker is a potential holoparasite used for biological control.To understand the efficacy and safety of Cuscuta campestris Yuncker in preventing and controlling Mikania micrantha H.B.K.The dodder C.campestris Yuncker were placed to 1 218 hm 2 area of M.micrantha H.B.K in 7 forest parks of Shenzhen and carried out filed monitoring.The results showed that the area of M.micrantha was about 792 hm 2(coverage rate 53%-73%),the rate of parasitism was 44%-87%,and the area of M.micrantha was decreased by 426 hm 2 after putting in the field of C.campestris Yuncker.The number of other plants affected by C.campestris was 153 species,belonging to 43 families from 109 genera.There are 15 species of phants were in contact with M.micrantha without harm(Grade 0).138 species of plants were in contact with M.micrantha and affected other phants(GradeⅠ-Ⅲ)without a deadly parasite plant except for M.micrantha.All results provided a scientific basis for generalizability of the control of M.micrantha in large area.
