| 摘 要： | 通过长期田间小区试验研究发现，在稻麦轮作土壤中，蚯蚓活动并不降低土壤全磷含量，有效磷含量呈直线上升趋势。在秸秆混施时，蚯蚓活动提高了树脂磷、NaOH磷含量，而超声磷含量降低，就总体而言，易于作物吸收的无机磷(如树脂磷和NaHCO，磷)含量有所升高。

| Abstract: | We have studied effects of earthworm activity on soil phosphorus in a wheat- rice soil in enclosures for a long period. It was found that earthworm had no significantly influence on total P, but available P raised steadily. When corn straw was incorporated into surface soil, both Resin- P and NaOH- P increased, while supersonic- P decreased. In a simply word, the content of inorganic phosphorus absorbed easily by crop increased such as Resin- P and NaHCO3- P. |
