摘要
以 2龄竹竹小爪螨 (OligonychusuramaEhara)量、3龄以上竹竹小爪螨量、3龄以上竹生理斑和真菌寄生斑、3龄以上竹南京裂爪螨 (SchizotetranychusnanjingensisMaetYuan)丝巢数、3龄以上竹竹缺爪螨 (AponychuscorpuzaeRimando)卵壳量为影响毛竹胸围的因子 ,应用灰色理论分析 3种螨害及其它因素对毛竹胸围的影响 .结果表明 :对毛竹胸围的危害大小序列为
selecting the amount of Oligongchus.urama in 2-aged bamboo,in over 3-aged bamboo,the amount of brown spot in over 3-aged bamboo,Schizotetranychus nanjingensis nest in bamboos more than 3 years old,Aponychus corpuzae egg crust in over 3-aged bamboos as effect factors on bamboo's bust,the paper analysed the relations between the factors and the bamboo's bust by gray theory.The results indicated that their sequence of damaging the bamboo was Schizotetranychus nanjingensis,Aponychus corpuzae,disease spots,and Oligongchus.urama.
