硫酸锌１０００倍液对肿囊腐霉与禾谷镰刀菌的抑菌半径分别为１６ｍｍ、２ｍｍ，而同一浓度的杀菌剂普力克为３４ｍｍ与０。盆栽试验结果表明，４～６ｇＺｎＳＯ４分批施入再接肿囊腐霉的发病率在２５％～１７％，接禾谷镰刀菌的发病率在１７％，均低于对照区５０％。１０ｍｌ普力克分批施入盆土内，然后分别接入两菌，均未见发病。ＺｎＳＯ４以６６７ｍ２１５～２ｋｇ的用量与其他肥料组配成种肥，在大田防治玉米茎基腐病的效果为７９６５％～８６５８％。 The antibacterial radius of zinc sulphate 1000 times against Pythium cyst and Fusarium graminearum was 16mm and 2mm, respectively, while the same concentration of bactericides Pulk was 34mm and 0. The results of pot experiment showed that the incidence of Pythium infants was in the range of 25% -17% and the incidence of Fusarium graminearum was 17% in 4 ~ 6g ZnSO4, which was lower than 50% of the control. 10ml 普利克 batches into the basin soil, and then access to two bacteria, were not seen. ZnSO4 with 667m21  5 ~ 2kg dosage and other fertilizers grouping into fertilizer, corn in the field to control stem-based rot effect of 79  65% ~ 86  58%.
