摘 要: | 对新疆天山北坡经济带滴灌棉田不同年限的连作耕地土壤质量演变趋势分析结果表明.研究区土壤肥力质量总体呈上升趋势。农业土壤的有机质含量先升后降,平均含量整体增加;全氮和速效磷含量呈S型上升趋势,局部地区有积累趋势;速效钾则成明显下降趋势。地区差异从时间跨度上看,土壤肥力的总体水平呈增加趋势,但在水平和变化上都存在明显的地区差异。

Abstract: | Drop irrigation of cotton field different time limit to make farmland soil quality to turn into trend analysis a result enunciation to Tianshan's north ascent economy in Xinjiang, study area soil fatty dint quality total present up-trend.The organic quality content of agriculture soil declines after rising first and the average content is whole to increase;Whole nitrogens with soon the effect Lin content present an up-trend and there is backlog trend in partial region;Soon the effect potassium then becomes to obviously descend trend.The region difference acrosses a degree to up see from time and the total level of the soil fatty dint presents increment trend, but all exists obvious region difference in level and variety tops. |
