摘　　要：目的以喷施4种杀菌剂防治马铃薯Y病毒病的样品为试验原料,研究防效与干物质、淀粉、还原糖和维生素C含量之间关系,分析各营养成分之间的相关性。方法在国家标准基础上稍加改动测定营养成分,采用矩阵散点图、标准化残差P-P图、一元线性回归分析防效与营养成分及各营养成分之间的相关性。结果防效与干物质、维生素C和淀粉含量之间呈正相关,干物质含量与淀粉含量、维生素C呈正相关,维生素C含量与淀粉含量呈正相关,还原糖含量与维生素C含量、淀粉含量、干物质含量和平均防效四者之间无显著相关性。结论4种杀菌剂中防效最好的为喷施5%氨基寡糖素水剂中剂量,且采收该小区马铃薯干物质含量、淀粉含量和维生素C含量最高。研究结果可为种植马铃薯防治Y病毒病筛选最佳药剂,为马铃薯病害防治与营养成分之间相关性提供数据支撑。Objective To study the relationship between control effect and content of dry matter,starch,reducing sugar and vitamin C,and analyze the correlation between the nutrients,using the samples sprayed with 4 fungicides against Solanum tuberosum virus Y disease as test materials.Methods On the basis of the national standard,the nutritional components were determined with a little modification,the correlation between the control effects and nutrient composition and each nutrient ingredient were analyzed by matrix scatter plot,standardized residual P-P plot and unary linear regression.Results The control effect was positively correlated with dry matter content,vitamin C content and starch content,dry matter content was positively correlated with starch content and vitamin C content;vitamin C content was positively correlated with starch content;while there was no significant correlation between reducing sugar content and vitamin C content,starch content,dry matter content and average control effects.Conclusion Among the 4 kinds of fungicides,the best control effect is spraying 5%amino-oligosaccharide at the medium dose,and the Solanum tuberosum dry matter content,starch content and vitamin C content are the highest in the harvesting plot.Research results can be used to screen the best pesticides for planting Solanum tuberosum to prevent and control Y virus disease,provide data support for the correlation between Solanum tuberosum disease control and nutritional components.
