Abstract:

采用盆栽试验的方法,于两个番茄品种旭日与金龙粉王育苗时分别接种G.mosseae,以明确该AM真菌在培育壮苗中的潜力。结果表明,G.mosseae显著的改善了两个番茄品种幼苗的素质,但是金龙粉王较旭日的接种效应明显。旭日与金龙粉王接种G.mosseae后,壮苗指数分别为相应不接种处理的2.38倍与3.49倍。菌根化幼苗的健壮生长在一定程度上依赖于G.mosseae对氮、磷养分吸收的显著促进作用。G.mosseae对氮吸收的菌根效应分别为47.50%与87.52%,对磷吸收的菌根效应分别为23.08%与64.74%。结果表明,将该AM真菌作为潜在的生物肥料引入设施番茄生产培育健壮幼苗是可行的。
