摘要
为研究间作功能植物对茶园主要害虫茶小绿叶蝉的影响,于2017-2018年在福建省泉州市安溪县茶园间作白三叶Trifolium repens L.、金花菜Medicago hispida Gaertn.、金盏菊Calendula officinalis L.,以自然留养杂草茶园为对照,用网捕法采集茶小绿叶蝉并于室内计数,镜检剥查法调查其茶梢着卵量。结果表明,在4种不同生境管理茶园网捕茶小绿叶蝉总个体数及每月个体数均无显著差异;茶小绿叶蝉个体数分别在2017年8月与2018年6月达到高峰。茶梢各节间着卵量不同,主要产卵在顶芽之下第2~5节间,以第4节着卵量最多。间作金盏菊茶园茶小绿叶蝉在茶梢第1节着卵量显著高于间作白三叶和金花菜茶园。不同生境管理茶园茶小绿叶蝉在茶梢第4节着卵量从大到小依次为间作金盏菊(8.13)、间作金花菜(7.50)、自然留养杂草(7.17)和间作白三叶茶园(6.57)。不同时间段4种不同生境管理茶园茶小绿叶蝉在茶梢各节之间的着卵量存在差异,且均在9月上中旬着卵量达到高峰。在茶园间作功能植物,短期内未见其显著降低茶小绿叶蝉网捕量和茶梢着卵量的效应。
In order to investigate whether intercropping reduced the abundance and fecundity of tea green leafhopper(TGL) on tea shoots of Tieguanyin, a tea plantation at the Juyuan tea professional cooperative, Anxi, Quanzhou was intercropped separately with Trifolium repens L., Medicago hispida Gaertn., and Calendula officinalis L. Natural ground cover was used as a control treatment. Number of nymphs and adults, as well as eggs of TGL were dissected in a tea plantation and tea shoots from 2017 to 2018. The results showed that no significant difference could be found either in the total or the monthly abundances of TGL between intercropping treatments. The two peaks of TGL were in August 2017 and June 2018, respectively. The egg density of TGL laid at different positions of tea shoot were different: TGL mainly laid eggs in the second to fifth leaf internodes, with the most eggs in fourth leaf internode. The egg density of TGL laid in the first leaf internode in tea intercropped with C. officinalis was significantly higher than that in tea intercropped with T. repens or M. hispida. The egg densities of TGL laid in the fourth leaf internode from high to low were in tea intercropped with C. officinalis(8.13), in tea intercropped with M. hispida(7.50), natural ground cover(7.17), and in tea intercropped with T. repens(6.57). The egg density of TGL in different leaf internodes of tea shoots was different in each sampling.Egg density of TGL showed one population peak, in early to mid-September. In conclusion, at least in a short-term, there was no obvious reduction in the abundance or in the egg density of TGL on the tea shoots in the intercropped treatments.
