本文经过四年的试验及多次的土壤调查,科学地总结出武威市川区土壤养分存在的问题是缺磷、少氮、有机质较缺。而物理性状(除土壤板结外)基本是良好的土壤物理构造。依理化现状和试验结果,提出农田土壤四级肥力指标。根据该论断可为武威市制定农业区划,进行农、林、牧合理布局,建设高产稳产农田的改土和培肥(特别是施用化肥)提供了科学依据.
After four years of experiments and several soil surveys, this paper scientifically sums up the problems of soil nutrients in Wuchuan City are phosphorus deficiency, less nitrogen and lack of organic matter. Physical properties (except for soil compaction) are generally good soil physical structures. Based on the status quo and the test results, four soil fertility indicators of farmland were proposed. According to this conclusion, we can provide a scientific basis for the formulation of agriculture zoning, the rational distribution of agriculture, forestry and animal husbandry in Wuwei City, and the improvement of soil fertility and fertilization (especially the application of fertilizers) in high and stable yield farmland.
