[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。
[Objective] To comprehensively understand the quality of soil in Daizhuang organic paddy soils and find out the status of soil fertility. [Method] After the rice harvesting ended, soil samples were taken from different plots and plots. [Result] The contents of organic matter in the soil of Daizhuang organic paddy soil generally increased, while the contents of nitrogen, phosphorus and potassium in the soil were generally low. The content of nitrogen and phosphorus decreased slightly and the content of potassium increased slightly in the organic rice - Soil nitrogen, phosphorus and potassium decreased in wheat rotation mode. [Conclusion] It is of great significance to popularize the development of organic rice-safflower turf to improve soil structure and improve soil fertility in organic paddy fields.
