摘要
立枯丝核菌病(Rhizoctonia solani)严重制约了马铃薯的产业化发展.本研究中通过设置马铃薯原种种薯催芽、切块及种薯质量大小处理,原原种包衣等处理探讨其对立枯丝核菌病害防控的影响.结果表明,6月17日原种催芽、整薯和大薯处理与不催芽、切块和小薯处理各发病等级占比差异不显著;原原种包衣处理的病害发病等级差异不显著.然而,6月21日原种催芽、整薯和大薯处理3级病害发病率显著降低,且原原种包衣大薯处理的病害等级显著低于包衣小薯处理.种薯包衣、催芽、整薯和大种薯处理方式能有效降低生长早期立枯丝核菌病害危害程度,间接证实了种薯芽况良好和出苗速度快对降低立枯丝核菌危害的有效性.因此,在马铃薯生产中采取适当的质量管控技术措施,可以有效控制病害,提升种薯质量.
Abstract
Rhizoctonia solani seriously hinders the industrialization of potato production.This study investigated the effect of the factors on the control of Rhizoctonia solani disease by sprouting,cutting,quality treatment and coating treatments.The results showed that there was no significant difference in the proportion of disease grade between elite sprouted potatoes,whole seed and large tuber treatment,and unsprouted treatment.Similarly,there was no significant difference in disease grade between cut seed potatoes,small tuber treatment,and elite pre-coating treatment on June 17th.The incidence of grade three diseases was significantly reduced in the treatment of elite sprouted potatoes,whole seeds,and large tubers.Additionally,the disease grade in the treatment of pre-elite coated large tubers was notably lower than that in the treatment of coated small tubers on June 21th.Therefore,treatments involving coated seeds,sprouted potatoes,whole seeds,and large tubers can effectively reduce the degree of damage caused by Rhizoctonia solani disease in the early growth stage.These results also indirectly confirm that optimal germination conditions and rapid seed potato emergence can effectively reduce the damage caused by Rhizoctonia solani.In summary,implementing appropriate technical measures for quality control in potato production can effectively manage the disease and improve the quality of seed potatoes.
