- 摘要:
- 采用室内盆栽方法，在连作番茄土壤中接种1.0%、2.5%、5.0%的幼套球囊霉（Glomus etunicatum）和摩西球囊霉（Glomus mosseae），确定2种丛枝菌根真菌对连作土壤中番茄幼苗生长及土壤的影响。结果表明：2.5%用量下番茄幼苗及土壤理化各项指标变化显著。该添加量下，幼套球囊霉和摩西球囊霉菌的根系侵染率达到61%和80%；与对照（CK,不接种任何菌剂）相比，2种菌根真菌的根长增加了26.8%和42.4%；根系鲜质量增加了38.1%和33.3%；根系干质量增加了17.1%和17.1%；差异均达到显著水平。与播种前的土壤微生物数量相比，细菌数量显著减少了51.4％和38.4％；放线菌数量显著增加了23.2％和21.1%。土壤的全磷含量比播种前减少了33.0%和29.9%，高于CK的减少量；摩西球囊霉促进土壤速效氮的释放。总之，2种丛枝菌根真菌均可显著促进番茄连作土壤中番茄幼苗的生长和对磷素的吸收作用，以2.5%接种量效果最好，且同添加量下以摩西球囊霉的改善效果较好。
- Abstract:
- Influences of Glomus etunicatum and Glomus mosseae on tomato seedlings growth and soil characteristics were detected by pot experiments as plant grown in continuous cropping soil.Two fungi were inoculated into tomato soil with three levels,such as 1.0%,2.5%,and 5.0% in weight ratio.The results showed that two arbuscular mycorrhizal fungi stimulated tomato seedlings growth especially with 2.5% fungi in soil,the mycorrhizal infection rates of Glomus etunicatum and Glomus mosseae on tomato root were 61% and 80%,respectively.Tomato seedlings root length with Glomus etunicatum and Glomus mosseae were longer than seedlings without incubated fungi(CK) by 26.8% and 42.4%,respectively.Root fresh weight and dry weight of seedlings with Glomus etunicatum or Glomus mosseae were more than CK by 38.1% and 17.1% or 33.3% and 17.1%,respectively.Soil bacteria population with Glomus etunicatum and Glomus mosseae decreased by 51.4% and 38.4% compared with those of before planting.The number of actinomycetes increased than before planting by 23.2% and 21.1%,respectively.The total soil phosphorus content of 2.5% level with Glomus etunicatum and Glomus mosseae decreased by 33.0% and 29.9% compared with those of before sowing.Glomus mosseae promoted the release of soil available nitrogen.In short,two arbuscular mycorrhizal fungi stimulated tomato seedlings growth in continuous cropping under greenhouse and absorbent of phosphorus.The 2.5% fungi addition was the appropriate application of fungi,and the Glomus mosseae was the better one between two fungi.
