摘　　要：湖南秋马铃薯播种正值高温干旱,病毒病发生严重。该研究以“费乌瑞它”的脱毒微型薯和小个商品薯为试验材料,研究不同时期喷施抗病毒药剂盐酸吗啉胍对马铃薯生长及产量的影响。结果表明,不同种薯级别的马铃薯产量差异不显著。其中,小个商品薯各处理的产量在14.81~17.15t/hm^(2),平均产量高于脱毒微型薯。种薯级别和抗病毒药剂共同影响马铃薯的产量,仅齐苗期喷施药剂的小个商品薯的总产量、商品薯产量和商品薯率最高,分别为17.15t/hm^(2)、15.59t/hm^(2)、90.91%。The planting of autumn potatoes in Hunan is experiencing high temperature and drought,and serious viral diseases have occurred.In this paper,we used“Favourita”virus-free mini-potatoes and small commercial potatoes as materials to study the effects of spraying antiviral agent morpholinoguanidine hydrochloride in different periods on potato growth and yield.The results showed that there was no significant difference in the output of different seed po⁃tatoes.The yield of each treatment of small commercial potato was 14.81-17.15 t/hm^(2),and its average yield is higher than that of virus-free mini-tubers.The interaction of seed tuber grade and antiviral agents had a greater impact on potato yield.Only small commercial potatoes sprayed with chemicals during the seedling stage had the highest total potato yield,commercial potato yield and commercial potato rate,respectively 17.15 t/hm^(2),15.59 t/hm^(2) and 90.91%.
