摘　　要：为评价集约化农业经营模式对土壤养分的影响,以广东省惠州市平潭某农业为研究区,采用传统耕作方式下和集约化经营模式下的土壤样品为研究对象,基于单因素分析方法,建立数据统计分析模型,对土壤的养分变化进行评价.研究发现:集约化的管理模式更容易导致农田中的酸性增强,尤其是在塑料大棚中集约化耕作,土壤偏酸性明显.集约化的耕作是否会影响土壤容重与耕作的农业机器有关,研究区域多采用小型农业机器,对土壤压实作用不明显.受到气候和成土母质的影响,南方地区的土壤中铵态氮和速效磷等含量总体偏低,而集约化的种植会减少养分的淋失,加上人为的精准施肥,使土壤中的氮、磷更容易富集,土壤生产力更高.In order to evaluate the impact of intensive agricultural management model on soil nutrient,the Pingtan Four Seasons Green Base in Huizhou of Guangdong Province,was used as the research field,and the soil samples in the traditional farming mode and the intensive management mode,were used as research objects based on the single factor analysis method.We also build a statistical analysis model of the data to evaluate the nutrient changes in the soil.The study found that the intensive management model is more likely to lead to acidity enhancement in farmland,especially in intensive farming in plastic greenhouses,which makes the soil more acidic.Whether intensive farming will affect soil bulk density is mainly related to farming agricultural machinery.Small agricultural machines are used in the area of study,and soil compaction is not obvious.Affected by climate and soil parent material,ammonium nitrogen and available phosphorus in the soil in the south are generally low,while intensive planting reduces nutrient leaching,and artificial precision fertilization is nitrogen in the soil.Phosphorus is more easily enriched and soil productivity is higher.
