朝阳市龙城区耕地及果园土壤肥力状况调查

Survey on the Soil Fertility of Farmland and Orchard in Longcheng District of Chaoyang City

为摸清朝阳市龙城区的耕地质量状况,选取有代表性的土壤样品进行pH值、有机质、全氮、速效钾等16项养分指标的测试分析。分析结果表明:朝阳市龙城区土壤有机质含量稍缺,碱解氮含量较缺,有效磷和速效钾含量丰富;中量元素含量不缺;有效硼和有效铁含量缺乏,其他元素含量不缺;旱田土壤肥力高于果园土壤。

In order to make clear about the farmland quality in Longcheng district of Chaoyang city, test analysis is made on the 16 nutrient indexes of representative soil samples, including its pH values, organic matters, total nitrogen, and available potassium. The analysis results show that its soil organic matter contents are slightly insufficient, the content of alkali-hydrolyzable nitrogen is insufficient, the contents of available phosphorus and available potassium are rich, and there is no lack of secondary elements, available boron and available iron content are insufficient while there is no lack of the other elements, and soil fertility in dry land is superior to that of orchard soil.
