摘要
本研究选择了玉米-向日葵轮作(CS)与向日葵连作(SS)耕地两种种植模式进行试验研究。结果表明:在SS种植方式下,土壤pH值、碱化度均随时间呈上升趋势,水溶性总盐随时间呈下降趋势。在CS种植模式下,土壤pH值、碱化度和水溶性总盐均随时间变化呈下降趋势;CS下土壤盐碱特性随时间变化相比于SS有较为稳定。这些结果预示着河套灌区整体上土壤盐含量随时间逐渐降低,SS下土壤碱性随时间升高,CS下土壤碱性随时间降低。
Abstract
This study selected two lands with different cultivating methods (Corn-Sunflower Rotation (CS) and Sunflower continuous crop (SS)) in the HID. Results showed that the soil pH and exchange sodium percentage (ESP) had an increasing trend over time under the SS land, and total water-soluble salts had a decreasing trend over time. Under the CS land, the soil pH, ESP, and total water-soluble salts decreased with time; The changes in soil salinity and pH and ESP over time under the CS land were more stable than those under the SS land. These findings indicated that the overall soil salt content in the HID gradually decreased with time, and the soil pH and ESP increased with time under the SS land. Soil pH and ESP decreased with time under the CS land.
