本文对黑龙江省南部地区两种水稻土的有机质变化动态进行了模拟试验,建立土壤有机质动态变化的数学模型。结果表明,土壤有机质与肥力特性有很好的相关性,在分析预测的基础上提出保持土壤有机质宜适值的必要性和可能性。
In this paper, the dynamic changes of organic matter in two paddy soils in southern Heilongjiang Province were simulated to establish a mathematical model of the dynamic changes of soil organic matter. The results showed that there was a good correlation between soil organic matter and fertility characteristics. Based on the analysis and prediction, the necessity and possibility of maintaining proper soil organic matter were put forward.
