摘要
通过典型采样和室内理化分析,从土壤剖面构型、颗粒组成、养分特征、环境特性及适宜性等级等5个方面分析了典型紫色土的肥力特征,在此基础上,提出了紫色土持续利用的途径与对策。
Typical samples of purple soil in the middle part of Sichuan Basin were taken and used for physico - chemical analysis. The profile patterns, particle composition, nutrient characteristics, environmental characteristics and suitable grade of the soil were analyzed. Based on the results, some measures are proposed for its sustainable utilization
