摘　　要：为了解链霉菌水剂对草莓连作障碍的防治作用,进行了链霉菌(men-myco-93-63)水剂温室盆栽灌根试验和大棚栽培灌根试验。结果表明:温室盆栽链霉菌水剂处理草莓的开花率比对照高16%,平均果重高2.7g,植株死亡率下降16%,相对防效达57.1%;大棚栽培链霉菌水剂提高了单果重,植株死亡率下降17.3%,相对防效达50.6%。结论:链霉菌水剂能显著增强草莓的抗连作障碍能力。Tests of pouring root with Men-meyo-93-63 AS in field and greenhouse were conducted to know the effects of Men-meyo-93-63 AS（Aqueous Solution） on replant disease of strawberry.The results showed that the strawberry treated by Men-meyo-93-63 AS in greenhouse could not only improved the flowering rate by 16% and mean fruit weight to 2.7 g,but also reduced the plant mortality by 16 % and the control efficacy reached 57.1% compared with CK.The results of field experiment showed that the strawberry treated by Men-meyo-93-63 AS could improve the weight of each fruit and reduce the plant mortality by 17.3 %,meanwhile,the control efficacy was 50.6% compared with CK.Conclusion：it was believed that Men-meyo-93-63 AS was able to protect strawberry against replant disease remarkably.
