摘要: 【目的】研究不同改良措施下沙质土壤质地变化,为沙化土壤改良提供科学依据。【方法】以新疆南疆典型沙化土壤为研究对象,设置5种不同改良措施(种植燕麦(A1)、种植油菜+燕麦(A2)、种植燕麦+油菜秸秆翻耕+生物菌肥(A3)、种植燕麦+农家肥(A4)、种植燕麦+农家肥+生物菌肥(A5)),采用田间试验,分析不同改良措施对沙化土壤颗粒组成分形的影响。【结果】不同改良措施下土壤分形维数D值介于2.35~2.49,与对照相比,随着土层的加深,土壤的细颗粒物质的分形维数值呈增加趋势;土壤颗粒分形维数D值与黏粒呈极显著正相关,与细粉粒呈显著正相关,与砂粒呈显著负相关。【结论】农家肥或绿肥与生物菌肥配合施用,可有效改善沙化土壤的理化性状。

Abstract: 【Objective】 The objective of this work is to study the texture changes of sandy soil under different improvement measures with the view of providing scientific theoretical basis for the improvement of sandy soil in Southern Xinjiang.【Methods】 Five different improvement measures were applied to the sandy soils of southern Xinjiang, namely, planting oats (A1), planting rape + oats (A2), planting oats + rape straw tillage + biofertilizer (A3), planting oats + agrofertilizer (A4), planting oats + agrofertilizer + biofertilizer (A5), and the effect of the five different improvement measures on the sandy soils was analyzed through the field tests.【Results】 The results showed that the fractal dimension D values of the soil under different improvement measures ranged from 2.35 to 2.49. As the soil layer deepened, the fractal dimension values of fine particulate matter in the soil tended to increase compared to the control. The fractal dimension D of soil particles was positively correlated with clay particles and with fine powder particles, and negatively correlated with sand particles.【Conclusion】 Comprehensive analysis showed that the combination of farm manure or green manure with biological bacteria fertilizer can effectively improve the physical and chemical properties of the sandy soil.

Key words: improvement measures; soil particle size; fractal dimension; soil physicochemical properties
