扬州市郊区设施土壤障碍因子调查分析

Investigation and Analysis of Obstacle Factors of Facility Soil in the Suburb of Yangzhou

为摸清扬州市郊区设施土壤障碍因子,更好地指导耕地质量提升与作物科学施肥,在扬州市郊区设施农业园采集具有代表性的土壤样品,对采集到的70个设施土壤样品进行基本理化性状的测定。结果表明,土壤pH值较低、部分有效态微量元素含量过低、大棚连作等是影响扬州市郊区设施土壤生产功能的主要障碍因子。为提高土壤肥力,可以增施有机肥、微生物肥料和中量元素肥料来补充土壤缺乏元素,使土壤元素平衡,以此促进作物生长。

In order to clarify obstacle factors of facility soil in the suburbs of Yangzhou City,and better guide the improvement of arable land quality and scientific fertilization of crops,representative soil samples were collected in the facility agricultural park in the suburb of Yangzhou City,and the basic physical and chemical properties of 70 collected facility soil samples were determined.The results showed that the low pH value of soil,the low content of some available trace elements,and the continuous cropping in greenhouse were the main obstacle factors affecting the production function of the facility soil in the suburb of Yangzhou City.In order to improve soil fertility,organic fertilizer,microbial fertilizer and medium element fertilizer can be added to supplement soil elements lacking in the soil,and balance soil elements,so as to promote crop growth.
