草莓重茬连作,会造成植株生长弱,侧芽分生少,病虫害重,果个小,品质差,产量低。这种现象称连作障碍。据调查,引起草莓连作障碍的原因,病虫害占50%,种苗带毒衰退占25%,土壤理化性状恶化和营养元素缺乏、忌地占25%。克服连作障碍的措施为:
Continuous cropping strawberries, will result in weak plant growth, fewer lateral buds, pests and diseases, fruit small, poor quality, low yield. This phenomenon is called continuous obstacles. According to the survey, the cause of strawberries continuous cropping obstacles, pests and diseases accounted for 50%, seedling poisoning recession accounted for 25% of the deterioration of soil physical and chemical properties and lack of nutrients, to avoid accounting for 25%. Measures to overcome the continuous obstacles:
