Comprehensive Evaluation of Soil Quality of Fruit and Vegetable Bases in Raoyang County,Hebei Province
[Objective]To reveal the present situation and problems of soil in Beijing-Tianjin-Hebei fruit and vegetable base.[Method]Taking soil of Raoyang fruit and vegetable base as the evaluation object in Hebei Province,12 soil samples were collected,the main physical and chemical property indicators were determined,the soil salinity was evaluated,and correlation analysis was carried out;the fuzzy evaluation method was used to evaluate the soil fertility;the status of soil heavy metals was evaluated by the comprehensive quality impact index evalua-tion method.[Result]The soil in Raoyang fruit and vegetable base was alkaline,and the soil appeared weak secondary salinization.The electri-cal conductivity increased with the increase of salt content,and the phenomenon of alkalization occurred at the same time as the salinization.The soil fertility level was at a moderate level.The evaluation results of soil heavy metal pollution showed that different degrees of heavy metal accu-mulation occurred in the study area,which may be related to the unreasonable fertilization methods,which had potential risks and needs to be paid attention to.The conversion of orchards to greenhouse vegetable cultivation significantly reduced the content of soil organic matter and in-creased the risk of soil salinization.[Conclusion]The research results provide scientific basis for the rational use of land,rational fertilization,soil nutrient management and high-quality fruit and vegetable production in the fruit and vegetable base of Raoyang County.
