为研究6%抗坏血酸水剂对马铃薯晚疫病的防治效果和对马铃薯产量的影响,在贵阳和毕节马铃薯种植地,于马铃薯生长幼苗期、块茎形成期和块茎膨大期喷施不同浓度的6%抗坏血酸水剂。结果表明:6%抗坏血酸水剂1000倍液的防治效果较好,施药后第14~21 d 时平均防治效果可达75.09%~80.74%,显著降低了马铃薯晚疫病的发生,同时能增加单位面积的块茎产量,平均增产21.59%。
為研究6%抗壞血痠水劑對馬鈴藷晚疫病的防治效果和對馬鈴藷產量的影響,在貴暘和畢節馬鈴藷種植地,于馬鈴藷生長幼苗期、塊莖形成期和塊莖膨大期噴施不同濃度的6%抗壞血痠水劑。結果錶明:6%抗壞血痠水劑1000倍液的防治效果較好,施藥後第14~21 d 時平均防治效果可達75.09%~80.74%,顯著降低瞭馬鈴藷晚疫病的髮生,同時能增加單位麵積的塊莖產量,平均增產21.59%。

Potato plants were sprayed with different concentration of 6% ascorbic acid at seedling stage,tuber formative stage and tuber expansion stage in potato fields of Guiyang and Bijie City to study control effects of 6% ascorbic acid against potato late blight and yield of potato.The results showed that the average control effect of 6% ascorbic acid WA 1 000 on potato late blight reaches 75.09%~80.74%14~21 d after spraying,which can reduce occurrence of potato late blight significantly and increase potato tuber yield per unit area with 21.59% averagely.
