东营市农高区果树产地土壤环境状况分析

Analysis of Soil Environment Quality of Fruit Tree Producing Area in Dongying Agricultural High-tech Demonstration District

为摸清东营市农业高新技术产业示范区果树产地质量状况,指导当地果蔬农产品安全清洁生产,对东营农高区果树产地的土壤有机质、pH、容重、粒径组成、盐分、速效养分及重金属等指标进行了抽样调查分析。结果表明,土壤有机质含量0.61%-1.01%,有机质含量不高,且高钾低氮低磷,需要培肥土壤。土壤pH均高于8.25,盐分含量0.12%-0.18%之间,说明调查区土壤轻度盐渍化。土壤中细沙粒比例较高,属于砂质壤土。调查点土壤重金属镉、汞、铜、铅、铬及砷含量均低于《绿色食品产地环境质量标准》中规定的重金属含量限值,可以实现果品的清洁安全生产。

In order to inspect soil environment quality in fruit tree producing area in Dongying agriculturalhigh-tech demonstration district and guide the safety and cleaner production of local fruit and vegetable, soilorganic matter, pH, bulk density, particle size, salt, available nutrient and heavy metal content were analyzedby sampling survey. The results showed that soil organic matter content was low with the range of 0.61% to1.01%, K content was high while N and P content were low, which indicating the need for enriching the soilfertility. The pH was higher than 8.25 and the content of salt was between 0.12% and 0.18%, which suggestedthat this area was of light salinization. The ratio of sand grain was relatively high and the soil belonged to sandyloam. Contents of Cd, Hg, Cu, Pb, Cr and As were lower than the limit value of＂Environmental QualityStandard of Green Food＂, which could realize safety and cleaner production of fruit.
