皮墨垦区沙地枣园土壤特性分析

摘要

To provide a basis for efficient utilization of fertilizer and soil fertility cultivation measures, The Nutrient, the physical and chemical properties of sandy land in the jujube orchard in the Pimo reclamation area were measured and analyzed. Results show that the degree of the soil salinization is low. The soil is alkaline and has loose soil structure. The soil field capacity is small. The contents of organic matter, total nitrogen, total potassium, hydrolytic nitrogen and soil available phosphorus are very low. The contents of total phosphorus, available K, exchangeable Mg are medium;Exchangeable calcium content is high.%为研究沙地枣园的土壤地力培肥和水肥高效利用措施提供基础，对皮墨垦区沙地枣园土壤养分及理化特性进行分析。结果表明：试验区土壤盐渍化程度低，土壤为碱性，土壤结构疏松，田间持水量较小，土壤有机质、全氮、全钾、水解氮、有效磷含量极低，全磷、速效钾、交换性镁含量中等，交换性钙含量高。
