摘要 为摸清大洼县的耕地质量状况,选取有代表性的水稻田、蔬菜田及芦苇田土壤样品,进行pH值、有机质、全氮等16项养分指标的测试分析。分析结果表明:氮素严重缺乏,磷素含量中等,钾素含量丰富;中量元素除钙素外基本不缺;微量营养元素除硼和钼缺乏外,其他很丰富;蔬菜田土壤的肥力状况最好,其次是芦苇田土壤,水稻田土壤的肥力状况最差。 Soil samples of representative paddy fields, vegetable fields, and reed fields were selected to make test analysis of 16 nutrient indexes, including pH values, organic matters, and total nitrogen in an effort to find out the farmland quality in Dawa County. The results show that there is significant lack of nitrogen, the phosphorus content is at a medium level, the potassium content is rich, there is no lack of secondary elements except for calcium, micronutrients are abundant except for boron and molybdenum, and the soil fertility in the vegetable fields are excellent followed by that of reed fields and the soil fertility in paddy field is the worst.
