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。
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 Loll- um 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 greater potential to control M. incognita than in control pots. In general, plant identities have a plant diversity.
