1978～1982年,全苏科学研究试验站研究了微量元素对马铃薯黑胫病、软腐病和其它病害的影响。于播种前将0.5％硫酸锌溶液(每吨块茎用15～20公升)喷于种薯块茎上,对照薯块喷等量清水,结果经硫酸锌处理者,加特钦斯基亩产2467公斤,较对照增产554公斤,星火和食用19也分别比对照增产328公斤和140公斤; From 1978 to 1982, the All-Su research station studied the effects of trace elements on black shank, soft rot and other diseases. 0.5% zinc sulfate solution (15-20 liters per ton of tuber) was sprayed on the seed tubers before sowing, and the equivalent amount of water was sprayed on the control tubers. As a result, the zinc sulfate-treated persons and the Gatschinsk yield 2467 kg per mu , 554 kilograms more than the control, Spark and food 19 also increased 328 kilograms and 140 kilograms respectively compared with the control;
