摘要
研究在低磷的南方酸性红壤中,3种磷水平(20、40、60 m g/kg)下,接种丛枝菌根真菌G.m osseae和G lom us versif orm e对玉米营养生长的影响。结果表明,菌根的形成可使玉米的株高、鲜重增加,促进玉米的营养生长;在低磷水平下,菌根侵染率最高,玉米的株高、鲜重增加也最显著,其中接种G.m osseae的处理其株高和茎叶鲜重的增加达到极显著水平。
Inoculating with Glomus mosseae and G. versiforme of arbuscular mycorrhizal fungi （AMF） in three phosphorus levels of 20, 40 and 60 mg/kg in acid red soil of south China to study the effects of AMF on maize plant growth. The results showed that the plant height and biomass increased. The mycorrhiza promoted the vegetative growth of maize plant. The myeorrhizal colonizatioa rate was highest when phosphorus level was 20 mg/kg. Inoculated with G. mosseae, the plant height and biomass increased most significantly.
