四种环境材料单施对煤矿区土壤结构和性状的影响研究OA北大核心CSTPCD
Effects of a single application of four environmental materials on soil structure and properties in a coal mining area
为解决煤矿区土地复垦中表层土壤结构差、持水能力低和养分贫瘠等问题,通过土壤培养模拟试验,研究了单施聚丙烯酸钾、黑矾、生化腐植酸和煤基腐植酸等4种材料对土壤改良的效果,并确定了适宜的施用量.结果表明:与对照(CK)相比,4种材料中聚丙烯酸钾能显著降低土壤容重,提高孔隙度和田间持水量,其添加量5 g·kg-1施用7d时,容重较CK降低了14.02%,孔隙度、田间持水量分别提高了28.31%、54.32%;黑矾能降低土壤pH和速效养分,当添加量5 g·…查看全部>>
The purpose of this study was to address the problems caused by poor surface soil structure,low water holding capacity,and nutrient depletion during land reclamation in a coal mining area.Potassium polyacrylate,black alum,biochemical humic acid,and coal-based humic acid were individually added to improve the properties of the soil,which were evaluated with a soil incubation simulation test.For the control(CK),no materials were added.This study investigated t…查看全部>>
