摘    要:通过日光温室小区试验研究了连作草莓的生长发育状况及根部病害发生情况。结果表明:连作草莓生长发育不良,主要表现在株高下降、叶片数减少、生物量下降、生育期延迟、产量下降等方面。同时连作草莓根系抗病力降低,导致土传根部病害的严重发生。连作2年的草莓植株在定植1个月后,病情指数已明显高于正茬处理,生长中期病情指数为正茬处理的2 2倍,最终连作2年处理的死苗率为40 9%,减产50 1%。

关 键 词:草莓  连作  生长发育  根病

Abstract:The growth, development, and root disease of strawberry under continuous cropping were studied through greenhouse trials. The results showed that after being planted year after year in the same field, the growth and development of strawberry were depressed. Plant height was shorter, leaves became less, root biomass and canopy were smaller, development period was delayed, and yield was reduced. At the same time resistance of roots was weakened and root diseases became serious. The disease index after two years continuous cropping treatment was higher than that of first-planting treatment after beginning, and it became 2.2 times as high in the middle of the whole period. In the end of growth period, the rate of plant death and yield decreased following two years continuous cropping treatment were 40.9 per cent and 50.1 per cent respectively.
Keywords:strawberry  continuous cropping  growth  root diseases
