摘要:
 以国槐树穴土壤为研究对象，进行树篦子、草皮、透水砖、鹅卵石、木片和无覆盖6种覆盖处理，2 a后测定树穴土壤理化性质。结果表明，树穴覆盖对0~10 cm土层的土壤理化性质影响较大，其中木片覆盖能显著改善土壤理化性质，使土壤容重降低8.72%，总孔隙度提高19.81%，有机质、全氮、碱解氮、速效磷和速效钾含量分别提高64.65%、 60.34%、110.54%、107.08%、62.34%；透水砖覆盖会压实树穴土壤；树篦子、鹅卵石和草皮覆盖对土壤理化性质无显著影响。树穴覆盖对10~20 cm土层土壤理化性质的影响程度较0~10 cm土层有所减弱，对20 cm以下的土壤理化性质无显著影响。
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.
