天津地区不同年限设施土壤pH及酶活性变化
Changes of pH and Enzyme Activities in Greenhouse Soils of Different Planting Years in Tianjin
摘要
Abstract
In order to provide the scientific basis of preventing soils from degradation and promoting agriculture sustainable development, soil enzyme activities and pH were studied in the greenhouse vegetable soils under different planting years( 1 ,2,3,6 and 12 year) in Tianjin with the open field soil as control. The result indicated that soil urease 、catalase and intertase activity were higher in greenhouse vegetable soils than that in open'field soil,peroxi-dase activities were opposite. Soil urease increased gradually with the cultivation years,but soil catalase,peroxidase and intertase activity increased beginning,then decreased. Soil enzyme activities decreased with soil depths. Soil pH declined with the planting years.关键词
