摘要 [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. [目的]全面了解戴庄有机水稻田土壤的质量,摸清土壤肥力状况。[方法]有机水稻收割结束后,在不同片区、不同种植方式的田块取土化验分析。[结果]戴庄有机水稻田土壤有机质含量总体提高,土壤氮、磷、钾含量总体偏低,有机水稻-红花草轮作模式土壤中氮、磷含量有所下降,钾含量略有增加;有机水稻-小麦轮作模式土壤氮、磷、钾都有所下降。[结论]大力普及发展有机水稻-红花草轮作对改善有机水稻田土壤结构,提高土壤肥力有重要意义。
