摘要: 【目的】 明确供试生物菌肥对马铃薯4种土传病害病原菌(加利利链霉菌、大丽轮枝菌、尖孢镰刀菌和立枯丝核菌)的室内抑制效果。【方法】 通过菌丝生长速率法,对不同浓度生物菌肥(50、100、1 000 mg/L)处理下的马铃薯4种土传病害病原菌进行抑制效果测定,并测定了生物菌肥对4种病原菌的毒力。【结果】 生物菌肥对同种病原菌的抑制率会随着浓度的增加而增大;在浓度1 000 mg/L时对4种病原菌的抑制效果最佳,对加利利链霉菌和大丽轮枝菌的抑制率分别为97.44%和85.01%,对尖孢镰刀菌和立枯丝核菌的抑制率分别为76.62%和32.07%。生物菌肥对4种病原菌的毒力作用存在一定差异,对大丽轮枝菌和加利利链霉菌的EC50值较小,分别为18.251 mg/L和41.461 mg/L;对尖孢镰刀菌的EC50值为140.939 mg/L;对立枯丝核菌的EC50值最大,为18 632.649 mg/L。【结论】 供试生物菌肥对大丽轮枝菌和加利利链霉菌具有较强的抑制效果和毒力,对尖孢镰刀菌具有一定的抑制效果和毒力,但对立枯丝核菌的抑制效果和毒力较小。

Abstract: 【Objective】To determine the indoor inhibitory effect of the tested microbial fertilizers on the four soil-borne disease pathogens of potato(Streptomyces galilaeus,Verticillium dahliae,Fusarium oxysporum and Rhizoctonia solani).【Methods】By the method of mycelial growth rate,the inhibitory effect of four soil-borne disease pathogens of potato treated with different concentrations of microbial fertilizer(50,100,1 000 mg/L)was determined,and the effect of microbial fertilizer on the 4 pathogens toxicity was determined.【Results】The inhibition ratio of same pathogen was improved with the increase of concentration of microbial fertilizer;the greatest inhibitory effect showed when four pathogens treated with 1 000 mg/L microbial fertilizer,and the inhibition ratio of Streptomyces galilaeus and Verticillium dahliae were 97.44% and 85.01%,the inhibition ratio of Fusarium oxysporum and Rhizoctonia solani were 76.62% and 32.07%. The microbial fertilizer showed different toxicity effects on 4 pathogens,EC50 of Verticillium dahliae and Streptomyces galilaeus were smaller and were 18.251 mg/L and 41.461 mg/L;EC50 of Fusarium oxysporum was 140.939 mg/L,while EC50 of Rhizoctonia solani was the biggest(18 632.649 mg/L).【Conclusion】The tested microbial fertilizer had a strong inhibitory effect and toxicity against Verticillium dahliae and Streptomyces galilaeus,and has a certain inhibitory effect and toxicity against Fusarium oxysporum,but it has a lesser inhibitory effect and toxicity against Rhizoctonia solani.
