| Abstract: | Objective] The aim was to explore soil quality and fertility of organic rice fields in Daizhuang Village. Method] The analysis was made based on soil samples from different areas where planting methods varied after harvest of organic rice. Result] The content of organic matter improved generally in fields of organic rice in Daizhuang. Specifically, the contents of N, P and K were not high, and the contents of N and P declined in the fields with crop rotation of organic rice Astragalus sin# cus, but the content of K increased. Conclusion] It is of great significance for soil fertility to develop and promote crop rotation of organic rice Astragalus sinicus, which also advances quality of organic rice. |
