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 :南京裂爪螨大于竹缺爪螨大于生理斑和真菌寄生大于竹小爪螨
The results showed that the number of silkworm nematode (Olivonychusura maehara), the number of small bamboo mite (3rd instar), the third-generation bamboo physiological speckle and fungal parasitic spot, the number of silk nests of Schizotetranychus nanjingensis MaetYuan The amount of eggshell of Aponychus corpuzaeRimando was the factor that affected the bust of Phyllostachys pubescens, and the effects of three kinds of mite damage and other factors on the bust of Phyllostachys pubescens were analyzed by the gray theory.The results showed that the sequence of damage to bamboo bust was Nanjing Cleft paw mites larger than bamboo lack of mites than physiological spots and fungi parasitic than bamboo small claw mites
