山东乐陵河口地区土壤质量评价与地力提升技术研究
摘要
Abstract
Based on geochemical data obtained from the national proj ect about the prevention and control of soil contamination,soil chemical elements in Laoling Hekou area in Shandong province have been stud-ied.It is showed that among the first level nutritive elements in soil,organic matter,nitrogen and phos-phorus were relatively deficient,while potassium was rich.Meanwhile,in the second level nutritive ele-ments ,calcium oxide and magnesium oxide were relatively short and sulfur content was abundant.In other beneficial and trace nutritive elements,iron oxide,manganese,molybdenum and boron were deficient, while the content of chlorine was high and hardly lack.The main barriers for improving land productivity were soil salinization and soil heavy metal contamination.According to the values of soil integrated fertility index,combining with basic surveying results,some countermeasures are put forward to improve land pro-ductivity,such as scientific fertilization,elimination of soil obstacle,remediation of heavy metal con-taminated soil and other effective counermeasures.It will provide a good technological support for the planning and development of good quality and high benefit agriculture.关键词
