摘　　要：旨在满足马铃薯生产中茬口衔接、机械化生产技术应用、不利气候下稳产等对马铃薯出苗早、齐、壮的需求,以‘费乌瑞它’为供试品种,用基于有益活菌或工程菌提取物的5种生物制剂进行种薯处理,对多重性状进行了对比分析。5种生物制剂较常规化学制剂,均能够不同程度地促进种薯萌芽和芽根同生,出苗期提前2~7天,播种后49天的出苗率提高3.33%~17.78%。其中,表现最好的为酵母核苷酸衍生物和VDAL,种薯萌发和生根均显著高于对照。霜冻后,生物剂拌种处理在恢复前期促进植株生长,由此促进恢复后期的块茎发育,较常规化学处理增产8.39%~24.03%,体现了不同程度的保产效果。多马道黑、酵母核苷酸衍生物、根肽和VDAL体现出较好的保产效果,可作为种薯处理剂投入马铃薯生产。To meet the need of early-orderly-strong emergence of potato seedlings during season connection,the application of mechanized production technology and yield stability under adverse climatic conditions,‘Favorita’was chosen as the test material, and five biologicals based on beneficial bacteria and engineering bacteria extracts were selected as the seed dressing, and the multiple characters of potato were analyzed. The five biologicals could promote the germination of seed tuber and the growth of both bud and root, advance seedling emergence for 2-7 days, and increase the emergence rate 49 days after sowing for 3.33%-17.78%compared with the control group. The best two are the ramification of yeast nucleotides and VDAL, whose effect on germination and root growth of seed tuber are significantly better than that of the control. The bioagent dressing could accelerate the recovery of plants as well as the development of tubers after frost, with a yield-increasing of 8.39%-24.03% than that of the control, showing different levels of yield-stability effect.Four biologicals including Duomadaohe, ramification of yeast nucleotides, Gentai and VDAL are beneficial in stable production after frost and drought, and could be selected as seed tuber dressing in potato cultivation.
