Abstract:
Taking the soil with different planting years in the main production areas of protected cucumber in 8 counties of Hebei Province as the research object,the changes of physical and chemical properties of main root layer soil (0-40 cm) in different areas were investigated and studied by using the method of field investigation and indoor analysis,and the relationship between the changes of soil physical and chemical properties and planting years was analyzed,in order to provide reference basis for scientific water and fertilizer management of regional protected cucumber.The results showed that that there was excessive accumulation of soil nutrients in root layer of 8 regions,especially in Laoting.The content of nitrate nitrogen was 278.20 mg?kg-1,available phosphorus was 186.10 mg?kg-1,available potassium was 734.73 mg?kg-1,pH was 6.85,EC value was 769.97 μS?cm-1.The pH of root soil with planting years over 10 years showed a decreasing trend compared with that before 10 years.Soil salinization did not occur in other areas except greenhouse soil in Yongqing County.Soil acidification by furrow irrigation under mulch.Soluble salt content of root soil was increased by drip irrigation under mulch.
