摘要
本文从蜜蜂—草莓复合农田的病虫害方面分析生态效益,以危害较为普遍的灰霉病为分析对象,调查了在整个生育期的发生动态。结果表明,在发病高峰期前,蜜蜂—草莓复合农田的灰霉病发病率一直低于对照田,而且发病高峰以后发病率下降速度较对照田缓慢。蜜蜂—草莓复合农田比对照田节肢动物群落结构相对复杂,多样性较高,优势度较低,稳定性较优。根据实验实际投入、产出核算出经济效益,蜜蜂—草莓复合农田的经济效益明显高于对照田。
In this paper, the eco-efficiency of bee compound-strawberry fields from plant diseases and insect pests were analyzed, widely prevalent Botrytis cinerea was chosen as tested objects, its occurrence dynamics in the whole growth period was investigated. The results showed that the diseased fruit rate of Botrytis cinerea in bee compound-strawberry fields was always lower than that of CK before the peak, and the diseased fruit rate fell more slowly than CK. Structure of arthropod community in bee compound-strawberry fields was complex, diversity higher, dominance index lower than CK, and the stability of insect communities was superior than that of CK. According to the actual input and output accounting benefits, the economic benefit in bee compound-strawberry fields was significantly higher than that of control.
