摘要:

为探明临潼区不同树龄石榴园土壤养分和肥力状况,采集临潼区6家石榴园0~20 cm和20~40 cm 2个土层共28份土壤样品,分析检测土壤大、中、微量元素含量,评价石榴园土壤肥力状况。结果表明:随着种植年限的增加,石榴园0~20 cm和20~40 cm 2个土层的pH和各养分指标未表现出明显的变化规律;石榴园土壤平均pH>7.5,为碱性土壤;20~40 cm下层土壤中的大部分养分指标低于0~20 cm表层土壤;各园区土壤有机质、土壤全氮和土壤碱解氮大多处于中等水平,土壤有效磷、土壤速效钾、土壤有效钙和土壤有效锌处于高等水平,土壤有效镁、土壤有效铁、土壤有效锰和土壤有效硼处于中低等水平。建议石榴园区增施有机肥,适当增加氮肥施用量,适宜补充微量元素。

Abstract:

To investigate the soil nutrient and fertility status of pomegranate orchards with different ages in Lintong District, a total of 28 soil samples were collected from 6 pomegranate orchards in Lintong District in two soil layers of 0-20 cm and 20-40 cm, the contents of soil macroelement, medium and microelement were determined, and the soil fertility status of pomegranate orchards were evaluated. The results showed that with the increase of planting years, the pH and nutrient indexes of 0-20 cm and 20-40 cm soil layers in pomegranate orchard did not show obvious change patterns; the soil in pomegranate orchard had mean pH>7.5, which was alkaline; most of the nutrient indexes in the lower soil layer of 20-40 cm were lower than those in the surface soil layer of 0-20 cm; the soil organic matter, soil nitrogen and soil alkaline nitrogen were mostly at medium level. Soil effective phosphorus, soil quick-acting potassium, soil effective calcium and soil effective zinc were at high level, and soil effective magnesium, soil effective iron, soil effective manganese and soil effective boron were at medium-low level. It was suggested that pomegranate orchards should increase the application of organic fertilizers, appropriately increase the application of nitrogen fertilizers, and appropriately supplement the trace elements.
