摘 要:为充分阐明草皮生产对其生产基地土壤质量的影响,对长春市二道区朝阳沟草皮基地连续草皮生产7年土壤;哈尔滨市松北区乐业镇魏家屯连续草皮生产8年土壤40个样本进行了土壤性质测试分析与探讨。结果表明:连续7、8年草皮生产后,其基地土壤比表面增加;微团聚体组成中,<0.001 mm,0.001~0.005 mm粒级均增加,0.01~0.05 mm粒级均降低。pH值、CEC(阳离子交换量)、EC(电导率)变幅不大;有机质含量降低,降低幅度达20.00%以上。土壤腐殖质的胡敏酸碳/富里酸碳(HA/FA)比降低。土壤速效氮、磷、钾含量均降低,以磷、钾含量降低幅度较大,分别高达80.00%、65.00%以上。提高了外源施入氮、磷、钾素的吸附能力,降低其释放能力,特别是磷、钾素。调查结果,表明连续7、8年草皮生产对土壤物理性质及土壤肥力造成严重破坏。Soil properties of 40 samples were analysed and investigated about 7-8 years traditional sod-production soil from changchun and harbing to fullly illuminate effect of continuous annual carpet sod production on soil properties in this paper. The results showed after traditional 7 -8 years sod-production. Compared with the control, soil specific surface area (SSA) were increased,〈0. 001 mm,0. 001-0. 005 rnm grades of the content of gread group enhanced,while 0. 01-0. 05 mm grades decreased. Sod-production had no distinct effect on pH, electronic conduc-tivity, cation exchange capacity. Yet organic matter, available Nitrogen Phosphorus and Potassium were reduced through 7-8 years sod-pro- duction, organic matter was decreased to above 20. 00% ,and H/F decreased, available phosphorus was decreased to above 80. 00% and potassium was decreased to above 65.00%. After they added to sod-production soil, the adsorption capacities of Nitrogen Phosphate and potassium in sod-production of 7-8 years were increased, while the desorption capabilities of Nitrogen phosphate and potassium were decreased, especially phosphate and potassium. The results showed soil quality was severely damaged after continuous 7-8 years sod production.
