摘　　要：秸秆中植病生防菌埋入后,有效地解决了连作草莓由于土传病害而导致死苗严重的问题,同时也促进了草莓的生长.在初果期时,株高增加了12.5%,单株平均叶面积增加了22.0%,单株平均叶片数增加71.78%,每花茎平均果数增加47.4%,平均单果重增加39.2%,死苗率降低77.83%,产量提高了126.4%.Burying straws and biocontrol fungi into soil solved effectively the problem that soil transmitted diseases caused the severe strawberries death.And it also promoted the growth of strawberry.In the early period of fruiting stem length increased by 12.5%,average leaf area of each strawberry increased by 22.0%,the quantity of leaves increased by 71.78% on average,flowering stems increased by 47.4% in fruiting buds and 39.2% in fruit weight,seedling death percents lowered by 77.83% and the output increased by 126.4%.
