摘要:

在盆栽试验条件下,选取12种植物采用病土接种法,每盆种植1株番茄和4株伴生植物(1种:4株·盆-1,2种:各2株·盆-1,4种:各1株·盆-1),探究了1种、2种、4种伴生植物组合对番茄地下根结线虫及地上害虫白粉虱的控制情况。结果表明,1种植物伴生时,黑麦草所在整盆植株根结线虫卵数显著低于对照组(无伴生植物);高羊茅(Festuca arundinacea)、薄荷(Mentha haplocalyx)、芥菜(Lolium perene)、高丹草(Sorghum bicolor×S. sudanense)和万寿菊(Tagetes erecta)所伴生的番茄及伴生植物总根结线虫卵数较对照均有下降的趋势。2种植物伴生时,在11个组合中有5组伴生的番茄根结线虫卵数低于对照组;4种伴生植物组合中有3组所伴生的番茄根结线虫卵数低于对照组。另外,有伴生植物存在时,番茄地上白粉虱数量显著低于对照组。研究表明,植物物种自身特性比植物多样性在控制根结线虫方面更有潜力。

Abstract:

In the study, we selected 12 plant species to evaluate the influence of one, two and four plant species combinations on tomato growth and population suppression of the rootknot nematode, Meloidogyne incognita, and the whitefly, Trialeurodes vaporariorum in a pot trial. The addition of onecompanion plant species resulted in a lower number of M. incognita eggs in Lolium perenne and Mentha haplocalyx pots compared with control pots (without companion plants). Additionally, there was a decline in total number of the nematodes in the other companion plant treatments as well. Furthermore, the number of the T. vaporariorum was significantly lower in the presence of companion plant treatments than in control pots. In general, plant identities have a greater potential to control M. incognita than plant diversity.
