四种不同类型绿地土壤特征及其对植物根系活力的影响
Effects of the Soil Characteristics of Four Different Types of Green Space on Plant Root Activity
摘要
Abstract
In order to promote the management and improvement of city soil for Qingdao ,through the collection and analysis of the road green space ,the green land ,the residential green space and the park land soil samples in Chengyang district of Qingdao city ,the differences and correlation between soil compactness ,soil water content ,soil pH ,soil total N ,alkali hydrolyzable nitrogen ,soil total P ,available P ,available K ,and organic matter in different tree forest were compared and analyzed ,as well as its effect on plant root activity .The re‐sults showed that soil compactness ,soil water content ,soil total N ,alkali hydrolyzable nitrogen ,soil total P , available K ,organic matter and root activity showed some correlation ,which applied to the condition where the same kind of plants in the different kinds of greenbelt or different kinds of plants in the same greenbelt . Soil compactness was positively correlated with soil pH ,and which was negatively correlated with soil total N , alkali hydrolyzable nitrogen ,soil total P ,available P ,available K and organic matter .With soil compactness increasing ,its water content decreased ,soil pH increased ,organic matter ,total nitrogen and alkali hydrolyza‐ble nitrogen ,soil total P and available P phosphorus loss ,plant root activity decreased .关键词
