Selection of Mycorrhiza Fungi with Masson Pine and Their Inoculation-Effects in the Nursery

experiment of potted seedlings of Masson Pine inoculated with different inocula of mycorrhiza fungi has been carried out. The results showed that the Masson Pines which are typical species with ectomycorrhiza displayed distinct differences on the growth and the accumulation of N, P,K, to their seedlings, owing to the different inocula used. The species of P. t and S.p were the most suitable fungi for the seedlings. The results of raising seedlings in a nursery with P. t mycorrhiza further showed that the superb-species of the fungi were more favorable to the growth of Masson Pine seedlings, which not only promoted the growth of the seedlings but also accumulated more nutrients in all the roots, stems and leaves. Hole-through method was the best one for inoculating the inocula in the nursery.
