%X By using the principles and methods of niche, this paper studied the mineral nutrition niche of rice sheath blight fungus. The results showed that the mineral nutrition niche breadth of the fungus at rice tillering, booting, heading, and waxing stages was 0. 2710, 0. 3865, 0. 4252 and 0.4817, respectively, i. e. , increased with rice growth, but still comparatively narrower, indicating that rice sheath blight fungus only utilized smaller parts of mineral nutrients at various growth stages of rice. The fungus always gave priority to occupy the nutrition niches where Mg, Zn and Si contents were lower, suggesting that Mg, Zn and Si contents had close relations to the resistance of rice against rice sheath blight.
