耕地土壤中量元素和微量元素的丰缺是反映土壤肥力的重要标志之一。2007—2011年对全县农用耕地耕层土壤进行了全面取土化验,将各种中微量元素含量水平进行分级,分析各级别所占比重,初步掌握了耕地土壤中量元素和微量元素含量水平,为中、微量元素的施用决策提供了科学依据。一、土壤中微量元素含量水平与分级状况按照全国土壤养分含量分级标准,新野县土壤中、微量元素各等级面积和所占比重见表格。二、有效硫分级评价与施肥决策全县土壤有效硫含量变幅在3.4～95.9mg/kg,平均含量16.2mg/kg。整体来讲,有效硫含量中等偏下,要进一步提高作物的 Soil fertility and quantity of trace elements and trace elements in soil are one of the most important symbols of soil fertility. In 2007-2011, the soil testing of farmland plowed soil was carried out comprehensive soil testing to classify the contents of various trace elements, the proportion of each grade was analyzed, and the content of trace elements and trace elements in cultivated land was preliminary mastered , Which provided a scientific basis for the decision-making of the application of trace elements. First, the soil trace element levels and grading status According to the national soil nutrient content grading standards, Xinye County soil, trace elements of each grade area and the proportion see the table. Second, the effective sulfur classification and fertilization decision-making The county soil available sulfur content range of 3.4 ~ 95.9mg / kg, the average content of 16.2mg / kg. On the whole, the available sulfur content is moderately lower, and the crop needs to be further improved
