【目的】研究不同保护性耕作措施对土壤磷组分的影响,为旱农区磷素高效利用提供理论依据。【方法】于2022年研究四种耕作措施[免耕(NT);免耕秸秆覆盖(NTS);传统耕作秸秆覆盖(TS);传统耕作(T)]对小麦农田0~60 cm土层Resin-P、NaHCO_(3)-P、NaOH-P、HCl-P和Residual-P磷组分含量。【结果】随着土层加深,各处理磷组分含量均呈下降趋势,但残留磷含量变化不明显。0~20 cm土层NTS处理土壤总磷含量和有效磷含量较T分别显著增加了9.95%和22.14%,但在20~60 cm土层土壤总磷和有效磷含量变化不明显,相关分析表明土壤有效磷含量与土壤有机碳、土壤水分含量呈正相关,与土壤pH呈负相关。【结论】免耕+秸秆覆盖有利于土壤总磷和有效磷的积累与提高,秸秆覆盖还田可能通过影响土壤有机碳和土壤水分和pH,促进土壤磷的活化,提高作物对磷的利用效率。
