Abstract
By cultivation in the field,under the condition of monocropping and intercropping of maize and soybeen,the comparative study has been conducted on the phosphorus amount absorbed by crop,the acid phosphatase activity in rhizosphere soil and the biomass on the ground in different growth periods.The result shows that intercropping has an obvious effect on phosphorus amount absorbed by maize,acid phosphatase activity in the root border soil and biological outputs on the ground.The amount of phosphorus absorbed by maize,acid phosphatase activity in the root border soil and biological outputs on the ground increased by 31.64%,31.46%,47.04% than the corresponding single cropping.The amount of phosphorus absorbed by soybean and biological outputs on the ground reduced by 8.18% and 10.99% than the corresponding single cropping,the difference is not prominent.
