Abstract
Experiments were carried out to study the effects of P sources on phosphatase activity of rhizosphere and mycorrhizosphere of red clover inoculated with Glomus mosseae, and cultural system with three compartments was applied. The plants were harvested after 8 weeks, and measured for dry weight and P contents as well as soil phosphatase activity of root and hyphal compartment. The results showed that acid phosphatase activity was higher than alkaline phosphatase activity, and both of them were increased slightly after inoculation, especially supplied with organic phosphorus (Na-phytate). Acid phosphatase activity was higher than alkaline phosphatase in the mycorrhizosphere of all inoculated treatments. The dry weight, P content and total P uptake of the plants increased significantly after inoculating mycorrhizal fungus. The amount of P uptake by hyphae accounted for 43.1% of total P uptake of plants under applying KH2PO4, while the value was 60.8% under applying Na-phytate.
