盆栽试验表明,在肥力较低的灰棕紫泥沙土中接种VA菌根真菌(Glomus epigaeus 9)对蚕豆(Vicia faba)的磷、氮营养和生长以及产量、品质有明显的正连效应.接种VA菌根真菌的植株含磷、氮量都高于未接种VA菌根真菌的植株,表明VA菌很真菌能加强蚕豆对磷、氮的吸收.各处理间主根长,结荚数的差异均达显著水平.P+VAM与P处理之间以及VAM与对照之间须根着生密度、根粗、根干重、植株总高度、叶片总数分枝数、茎粗、茎数、茎干重、开花数、籽粒产量等的差异均达显著水平.其中以P+VAM处理的植株为最优,VAM处理的植株次之,表明在肥力较低的土壤上供给少量磷素,VA菌根真菌的效应更加显著.
Pot experiments showed that inoculation of VA mycorrhizal fungi (Glomus epigaeus 9) in low fertility limy purple soil had a significant positive effect on phosphorus, nitrogen nutrition and growth, yield and quality of Vicia faba. The plants with VA mycorrhizal fungi had higher phosphorus and nitrogen contents than those without VA mycorrhizal fungi, indicating that VA fungi could enhance the absorption of phosphorus and nitrogen in broad bean plants. Reached the significant level.P + VAM and P and between the VAM and the control must be based on the density, root thickness, root dry weight, total height of the plant, the total number of leaf branches, stem diameter, stem number, stem weight , Flowering number, grain yield, etc. Among them, plants treated with P + VAM were the best, followed by VAM plants, which indicated that a small amount of phosphorus, VA mycorrhizal fungi The effect is more pronounced.
