为了摸清辽西葡萄园根区土壤养分状况,2009年4月～5月,在辽西葡萄主产区选择34个代表性的葡萄园分3层采集0～60 cm根区土壤,测定了其养分含量。结果表明:辽西葡萄根区0～20 cm层土壤有机质、全氮、有效氮、速效磷和速效钾平均含量分别为:20.37 g kg-1、2.0 kg-1、162.7 mg kg-1、164.0 mg kg-1和393.6 mg kg-1;20～40 cm层分别为:14.75 g kg-1、1.6 g kg-1、121.1 mg kg-1、124.3 mg kg-1和293.5 mg kg-1;40～60 cm层分别为:14.34 g kg-1、1.4 g kg-1、96.8 mg kg-1、87.6 mg kg-1和205.4 mg kg-1。总体来看,辽西主产区葡萄园根区土壤有机质处于中等水平,全氮、有效氮、速效磷和速效钾含量处于高水平或过量水平,存在潜在的环境风险。同时,由于多年传统施肥习惯,导致养分在根区土壤表层大量累积,其中土壤有效氮含量三层之间均存在显著性差异;0～20 cm土层的有机质、全氮和速效钾含量与20～40 cm和40～60 cm土层之间存在显著性差异,但20～40 cm和40～60 cm土层之间不存在显著性差异;土壤有效磷含量0～20 cm土层与40～60 cm土层之间存在显著性差异,0～20 cm与20～40 cm土层和20～40 cm与40～60 cm土层之间不存在显著性差异。
In order to find out the soil nutrient status in the root zone of western Liaoning vineyards, from April to May 2009, 34 representative grapevines were selected in the main producing areas of western Liaoning to collect 0 ~ 60 cm root zone soils, content. The results showed that the average contents of soil organic matter, total nitrogen, available nitrogen, available phosphorus and available potassium in 0-20 cm layer in the root zone of western Liaoning were 20.37 g kg -1, 2.0 kg -1, 162.7 mg kg -1 and 164.0 mg kg-1, and 393.6 mg kg-1, respectively; and the layers of 20-40 cm were 14.75 g kg-1, 1.6 g kg- 1, 121.1 mg kg- 1, 124.3 mg kg- 1 and 293.5 mg kg- The 60 cm layers were 14.34 g kg -1, 1.4 g kg -1,96.8 mg kg -1, 187.6 mg kg -1 and 205.4 mg kg -1 respectively. In general, soil organic matter in the root zone of vineyards in the main producing areas of western Liaoning is at a medium level, and total nitrogen, available nitrogen, available phosphorus and available potassium are at high or excessive levels, with potential environmental risks. At the same time, due to many years of traditional fertilization practices, nutrient accumulation in the rootzone soil was significant, and there were significant differences among three layers of soil available N content. The content of organic matter, total nitrogen and available potassium in 0 ~ There was a significant difference between ~ 40 cm and 40 ~ 60 cm soil layers, but there was no significant difference between 20 ~ 40 cm and 40 ~ 60 cm soil layers. There was a significant difference between 60 cm soil layer and 0-20 cm soil layer and 20-40 cm soil layer and between 20-40 cm soil layer and 40-60 cm soil layer.
