广州地区草坪线虫初步调查鉴定

Preliminary survey and identification of grass carpey nematode in Guangzhou region

为了解广州地区草坪线虫种类的分布情况,从广州市12个不同地点的运动型、观赏型、游憩型草坪和草圃采集草根样品,经贝曼漏斗法分离线虫,用TAF固定液杀死,依甘油慢法制作玻片,采用deMan公式测量计算,按T Goodey和J B Goodey的分类系统进行鉴定,初步鉴定出线虫23种,其中6种为中国地理新记录。这些线虫种类中植物寄生线虫8种、植物病原线虫3种、食肉线虫5种、食菌线虫9种、食腐线虫6种,表明广州地区草坪线虫种类资源丰富,生物习性多样。

For get a clear idea of distribution of nematodes species existed on grass roots in Guangzhou, nematode specimens were extracted by Bearmann's funnel from grass roots of 12 different sports lawns in Guangzhou, killed with TAF stationary liquid, made into slides through glycerin slow method, measured according to deMan' formula 23 species of nematodes were identified using TGoodey & JBGoodey's classification system,which are 6 saprophagous, 9 feeding on fungal hyphae or bacteria, 5 sarcophagous, 3 plant pathogens, 8 plant parasites and 6 China new geography records The result showed the nematode species of grass lawn in Guangzhou are rich and its biological habits are multiple
