探讨了博罗县下村农场坡地赤红壤的结构特征及其生产意义。结果表明,下村农场坡地赤红壤的质地较粗,土壤的团聚体含量较高,土壤的孔隙性较差;土壤粘粒、有机质,尤其是后者对土壤结构状况影响很大,土壤结构系数与土壤粘粒含量呈显著正相关,土壤1—0.05mm粗微团聚体含量、10—0.25mm水稳性团聚体及其几何平均直径值,均与土壤有机质含量呈显著正相关。坡地土壤的开发利用,应注意防治水土流失,减少团聚体的破坏,并特别注重提高土壤有机质含量,以改善土壤结构状况。
This paper discussed the structural characteristics and the production significance of the latosolic red soil on the slope farmland of Boluo County. The results showed that the hilly red soil in Xia Village was coarse in texture, with high content of soil aggregates and poor soil porosity. Soil clay, organic matter, especially the latter, had a great influence on the soil structure. The soil structure coefficient and There was a significant positive correlation between the soil clay content and soil micro-aggregates content of 1-0.05mm, water-stable aggregates of 10-0.25mm and geometric mean diameter values of soil aggregates and soil organic matter content. The slope soil development and utilization should pay attention to prevention and control of soil erosion, reduce the destruction of aggregates, with particular emphasis on increasing soil organic matter content, in order to improve the soil structure.
