不同覆盖材料对城市树穴土壤理化性质的影响
Effects of Different Mulching Materials on the Soil Physicochemical Property of the Plant Pits in the Cities
摘要
Abstract
In this study,field experiment was employed to assess of different mulching materials (tree pit nets,turf,water permeable bricks,pebbles,and wood mulching) on the soil physicochemical properties of the plant pits after coving 2 years.The results showed that tree pits mulching had significant effect on the soil physicochemical properties at the depth 0-10 cm,the surface physicochemical property could be significantly improved (P＜0.05) with wood mulching:and soil bulk density decreased by 8.72％,the total porosity incrrased by 19.81 ％,organic matter,total nitrogen,alkali hydrolyzable nitrogen,available phosphorus and available potassium increased by 64.65 ％,60.34 ％,110.54 ％,107.08 ％ and 62.34 ％,respectively.Turf coverage could improve tree soil porosity and permeability in a certain degree.There was no significant difference in the physicochemical properties of the soil with tree pit nets,pebbles and turf.The effect of different mulching materials to 10-20 cm soil physicochemical property was weaker than that of 0-10 cm soil,soil under 20 cm had no correlation with different mulching materials in plant pits.关键词
