有机质与土壤肥力的关系极为密切。本文对朝阳地区主要耕地土壤的有机质含量与土壤常年产量的关系,耕地土壤的适宜有机质含量,低产、中产、高产土壤的有机质矿化率和年矿化量,有机肥料在低产、中产、高产土壤中的腐殖化系数分别作了研究,初步得到了有关指标和数据。根据试验结果,可以作为朝阳地区对有关土类指导合理施用有机肥料,保持耕地土壤有机质平衡的参考。
The relationship between organic matter and soil fertility is very close. In this paper, the relationship between organic matter content of main cultivated land and annual perennial yield in Chaoyang area, suitable organic matter content of cultivated land, organic matter mineralization rate and annual mineralization amount of low yielding, middle-yielding and high yielding soils, organic fertilizers in low, middle and high yielding soil In the humification coefficient were studied separately, initially got the relevant indicators and data. According to the test results, it can be used as a guide for the soil-based organic fertilizer management in the Chaoyang area to maintain the balance of soil organic matter in cultivated land.
