| Abstract: | In the greenhouse exper imen,t the grow th effect on C arnegiea gigantea seedlings wh ich w as app lied w ithAM fung i and fertilizers w as studied by Split p lo t design experimen.t The resu lts show ed that the percentage ofmycorrh izal infect ion of 3 AMF iso lates in Carneg iea gigantea w ere high, but theMycorrhizal dependency (MD ) ofCarneg iea g igantean belonged tom edium orw eak. G lomus caledonium 90036 treatm ent show ed the best mycorrhizaleffectiveness. When be ing fert ilized w ith N, P o rK w ithout inoculating w ith AMF, N app lication could markedlyimprove the he igh t grow th ofCarneg iea g igantean seed lings, butK and P didn t' indicated the same effects. How ever,the seedlings inocu lated w ith AMF couldn t' present grow th improvementwhen fertilized w ith N, and the interactionsbetw een K or P applicat ion and AMF inocu la tion w as negative. A ccord ing to the experimen,t the result thatCarneg iea g igantea inocu lated w ith AMF cou ld cut down N fertilizer app lication w as conv inced. |
