摘要
探讨了幼龄茶树与山毛豆、花生间作及覆盖蔗叶、芦苇叶对生物多样性和茶叶产量的影响。结果显示:幼龄茶园中茶行间种豆科作物并覆盖后,能提高茶园生物多样性,特别有利于增进蜘蛛等天敌的种类与数量及对害虫的生态控制能力,从而增加茶叶产量。其中,覆盖甘蔗叶与间作山毛豆效果更好,节肢动物多样性为0.8156,蚯蚓种群数量增加显著,产量明显提高。
This paper discussed influence of intercropping between young tea tree and tephrosia,peanut and mulching by sugarcane leaves,reed leaves to biological diversity and tea yield.The result shows that intercropping with soybean and covering can increase biological diversity of tea garden.Especially benefits spiders and other predators which enhance control of pests and increase the yield of tea.Among them,covering of sugarcane leaves and intercropping with tephrosia obtain better effect.The diversity of arthropod is 0.8156 and the number of earthworm increased significantly,so obviously improve the yield.
