Abstract: The contradiction between the insufficient supply of calcium (Ca) and the high demand of peanut
plants has become increasingly prominent, which has become one of the most important yield limiting factors of pea⁃
nut. Arbuscular mycorrhizal fungi (AMF) can improve plant roots in soil environment, enhance the absorption of nu⁃
trients and the resistance to stress. In this study, Huayu 22 and Huayu 25 were selected to set AMF and superphos⁃
phate single and compound treated in saline and non-saline soil to study the effects of AMF and superphosphate on
peanut growth, yield, and quality. The results showed that under the same compound fertilizer treatment, the peanut
plant biomass was increased, the total pot number, full pot number, double kernel number, 100 pot weight and 100
kernel weight per plant were increased, and the yield was thus increased. In saline soil, the compound effect of AMF
and superphosphate > AMF >superphosphate; in non-saline soil, the compound effect of AMF and superphos⁃
phate > superphosphate > AMF. AMF and superphosphate could significantly increase protein and oleic acid con⁃
tent and ratio of oleic acid to linoleic acid, reduce linoleic acid content, but had no significant effect on fat content.
This study provided a theoretical basis and technical support for the application of AMF and superphosphate in the
efficient production of peanuts in different soil types.

Key words: peanut, Arbuscular mycorrhizal fungi, superphosphate, yield, quality
