Effect of continuous cropping on the rhizosphere soil and growth of common buckwheat
Common buckwheat is a health-care crop, and continuous cropping is one of the main factors restricting its high-yielding. In order to clarify the mechanism of continuous cropping of buckwheat, 4, 5and 6 years continuous cropping treatments were set up. We obtained the following results. The availabl...

Common buckwheat is a health-care crop, and continuous cropping is one of the main factors restricting its high-yielding. In order to clarify the mechanism of continuous cropping of buckwheat, 4, 5and 6 years continuous cropping treatments were set up. We obtained the following results. The available nutrients content in rhizosphere soil, soil enzyme activity, leaf area, chlorophyll and soluble protein content, the peroxidase(POD) activity of leaves, agronomic traits, root index (except average diameter) of Fengtian1(FT1) decreased significantly with the increase of continuous cropping years. While, soil pH and the number of fungi in rhizosphere soil increased significantly, the number of bacteria in rhizosphere soil and the activity of catalase (CAT) and superoxide dismutase(SOD) in leaves first increased and then decreased. The yields of continuous cropping for 6 years were 12 times lower than the control crop. In conclusion, continuous cropping has certain effects on growth and yields of buckwheat. |
