| 为了综合评价秸秆配施蚯蚓对设施次生盐渍土的改良效果,采用室内土柱不同深度(0~10、10~30 cm和30~50 cm)原位土壤模拟实验,设置不同秸秆添加量及有无配施蚯蚓,从土壤养分、盐分离子含量方面阐述其对次生盐渍化温室土壤的改良效果,并给出研究区域最适宜的改良方法。结果表明,土壤Mg2+、SO42-、Cl-、Ca2+和Na+是供试土壤主要可溶性盐离子,土壤盐分和养分含量主要集中在0~10 cm土层。蚯蚓的添加可以促进秸秆降低0~10 cm土壤电导率(EC),但是盐分会汇聚到土壤深层。对比其他实验组,S2E(秸秆5 kg·m-2+蚯蚓50条·m-2)处理使0~10 cm土壤EC显著降低了56.04%。S2E处理主要通过降低0~10 cm土壤SO42-、Ca2+、Mg2+、K+、Na+含量和提升HCO-3含量来改变土壤主要盐分离子组成。蚯蚓可以促进秸秆提升0~10 cm和10~30 cm土壤的速效磷(AP)含量。低剂量秸秆配施蚯蚓有助于提升10~30 cm和30~50 cm土壤碱解氮(AN)含量。高剂量秸秆配施蚯蚓是10~30cm和30~50 cm土壤速效钾(AK)含量提升的主要原因。秸秆的添加是10~30 cm土壤有机质(OM)含量升高的主要原因。灰色关联度分析表明:S2E处理对0~10 cm和10~30 cm设施次生盐渍化土壤性质的改善效果最佳。S1E处理(秸秆2.5 kg·m-2+蚯蚓50条·m-2)对30~50 cm设施次生盐渍化土壤性质的改善效果最佳。研究表明,秸秆配施蚯蚓有效降低了次生盐渍化土壤盐分、增加了土壤养分含量,秸秆5 kg·m-2+蚯蚓50条·m-2对设施次生盐渍土(0~10 cm和10~30 cm)性质的改善效果最明显。 |

| To evaluate the effectiveness of integrating straw with earthworms for the remediation of secondary saline soils under controlled conditions, this study conducted simulation experiments employing indoor soil columns with in-situ soil at various depths(0-10, 10-30 cm, and 30-50 cm). This investigation focused on the impacts of the straw-earthworm combination on salinized greenhouse soil by analyzing soil nutrient concentrations and salt ion profiles, providing insights into optimal remediation strategies for the region. The results showed that the primary soluble salt ions were Mg2+, SO42-, Cl-, Ca2+, and Na+, with highest concentrations observed in the 0-10 cm layer. The introduction of earthworms reduced electrical conductivity(EC)within the 0-10 cm layer, although it caused salt to accumulate in deeper layers. Specifically, the S2E treatment(5 kg·m-2 of straw coupled with 50 earthworms·m-2)reduced EC in the 0-10 cm layer by 56.04% compared to other treatments. Moreover, the S2E treatment primarily altered the composition of major salt ions in the soil by reducing the concentrations of SO 2 4- Ca2+, Mg2+, K+, and Na+ in the 0-10 cm layer, while increasing HCO - 3 levels. Additionally, earthworm activity was associated with an increase in available phosphorus(AP)in both the 0-10 cm and 10-30 cm layers. A lower straw application rate in conjunction with earthworms enhanced ammonium nitrogen(AN)concentrations in the 10-30 cm and 30-50 cm layers, while a higher straw dosage primarily increased available potassium(AK)levels at these depths. The increase in organic matter(OM)in the 10-30 cm layer was primarily attributed to straw application. Grey relational analysis demonstrated that the S2E treatment significantly improved soil properties in the 0-10 cm and 10-30 cm layers, whereas the S1E treatment(2.5 kg·m-2 of straw with 50 earthworms·m-2)was most advantageous for the 30-50 cm layer. In summary, the synergistic application of straw and earthworms effectively reduced soil salinity and enhanced nutrient profiles, with the S2E treatment showing the most significant improvements in soil characteristics at the 0-10 cm and 10-30 cm depths. |
