摘要
通过采用以荒地退化红壤为对照,与造林、种稻、种植果树3种处理进行比较,研究在不同利用方式下对退化红壤肥力状况的影响。结果表明:不同利用方式对退化红壤的土壤养分状况、土壤酶活性等有显著的影响,其影响效果表现为:造林>水田>果园;同时还针对退化红壤提出了不同的合理利用模式。
According to the condition of fertility of the degenerated red soil on wasteland,compared with the Ⅰ-forestation,Ⅱ-growing the patty,Ⅲ-planting the fruit tree under the different exploitation methods.The effect of different application practice on condition of fertility of degenerated red soil on wasteland was studied.The results showed that the efficacy of the condition of nutrient of the soil and the activity of enzyme in soil was great by different application practices,and forestation>the paddy field>orchard. At the same time,aimed at the degenerated red soil,the different reasonable use models are put forward.
