研究施用不同浓度的植物源复合杀虫剂KKY对石榴园节肢动物群落的影响。结果表明,对照株及低浓度喷施株(600倍、700倍)的优势集中性表现为高-低 -高变化;高浓度喷施株表现相反趋势,为低 -高 -低;多样性水平低浓度喷施株高于高浓度喷施株。
The effects of KKY, a plant-source complex insecticide, on the arthropod community in pomegranate orchard were studied. The results showed that the dominant concentration of the control strain and the low concentration sprayed plants (600-fold and 700-fold) showed high-low-high change; the high-concentration sprayed plants showed the opposite trend of low-high-low; Spraying plants at low concentrations were higher than those at high concentrations.
