摘要
为探究AMF对番茄植株生长的影响及对根结线虫的抑制作用,通过温室盆栽试验,在番茄幼苗期接种摩西球囊霉(Funneliformis mosseae)与南方根结线虫2龄幼虫,并以不添加摩西球囊霉处理为对照.结果表明,与CK相比,接种AMF后,番茄幼苗地上部鲜、干质量均显著增加,分别增加18.1%、24.8%;根结线虫病病情指数降低 29.5%;植株中N、P、K含量分别增加6.9%、80.5%、63.0%;土壤铵态氮、硝态氮、有效磷、速效钾含量分别增加 6.8%、20.7%、8.1%、7.8%.可见,接种AMF具有促进番茄生长、抑制番茄根结线虫病的发生、增加植株养分及土壤速效养分含量的作用.
Abstract
To investigate the effects of arbuscular mycorrhizal fungi(AMF)on tomato plant growth and its inhibitory effect on root-knot nematodes,a greenhouse pot experiment was conducted.The Funneliformis mosseae was inoculated in tomato seedlings along with second-stage juveniles of southern root-knot nematodes,while a control group without AMF inoculation was set up.The results showed that compared to the control group,the aboveground fresh and dry mass of tomato seedlings significantly increased by 18.1%and 24.8%,respectively,after AMF inoculation.The disease index of root-knot nematode infection decreased by 29.5%.The content of N,P,and K in plants increased by 6.9%,80.5%,and 63.0%,respectively.Additionally,soil ammonium nitrogen,nitrate nitrogen,available phosphorus,and available potassium content increased by 6.8%,20.7%,8.1%,and 7.8%respectively after AMF inoculation.Overall,these findings demonstrate that AMF inoculation promotes tomato growth,suppresses the occurrence of root-knot nematode disease in tomatoes,and increases nutrient levels in both plants and soil.
