本文研究了五种利用方式对红壤水稳定性团聚体形成的影响。结果表明,>0.25mm水稳定性团聚体含量:林地>旱地>荒地>茶园>果园。水稳定性团聚体数量以及团聚的水稳定性均与有机质的含量呈正相关。红壤开垦后,有机质分解加快或补充减少是导致团聚体稳定性下降和水稳定团聚体减少的主要原因。同理,恢复和改良红壤结构性及结构稳定性的关键是增加有机质的投入。
This paper studied the effects of five kinds of utilization methods on the formation of water-stable aggregates in red soil. The results showed that> 0.25mm water-stable aggregates content: woodland> dry land> wasteland> tea garden> orchard. The number of water-stable aggregates and the water stability of the agglomeration were positively correlated with the organic matter content. After the reclamation of red soils, the acceleration of organic matter decomposition or the reduction of supplementation is the main reason for the decrease of the stability of aggregates and the decrease of water-stable aggregates. Similarly, the key to restoring and improving the structural and structural stability of red soils is to increase the input of organic matter.
