中文摘要	为探讨Arkadolith土壤改良剂对沙土理化性质以及沙生植物生长状况的改良效果,采用异地温室人工模拟试验的方法研究了改良剂不同施用率处理(CK:0%;A1:4%;A2:8%;A3:12%;A4:16%)对库布齐沙漠沙生植物群落优势种杨柴生长状况以及土壤理化性质的影响。试验结果表明,施用Arkadolith土壤改良剂能显著提高杨柴生长状况,施加改良剂4种处理新梢生长高比对照增加了4.35%~43.5%,植被叶片数呈:A4>A2>A3>A1>CK,杨柴地上生物量比对照增加了36.8%~168.5%,同时减小了植株的根冠比;施用Arkadolith土壤改良剂改善了植物体内的水分状况,增加了植株的吸水量,提高了杨柴在全天各时段的叶水势;施用Arkadolith土壤改良剂能改善土壤物理性状,降低土壤容重、提高土壤孔隙度、降低土壤渗透速度、增加田间持水量;并且能增加土壤养分储备,提高速效养分,缓解养分失衡
英文摘要	To find out the amelioration effect of Arkadolith,a new soil modifier on sandy soil physical and chemical properties and the growth ofAstragalusmongolicum,a dominant species in sandland community in Kubuqi Desert,effects of different application rate(CK:0%;A1:4%;A2:8%;A3:12%;A4:16%)of Arkadolith were compared by means of simulated experiment in laboratory.The results show that the application of Arkadolith can significantly improve the growth status ofAstragalusmongolicum,the growth of new shoots increase by 4.35%~43.5% and biomass increase by 36.8%~168.5% with the decrease of the root-shoot ratio at the same time,leaf numbers follows the order of A4>A2>A3>A1>CK.Meanwhile,use of Arkadolith increase plant water absorption,raise leaf water potential,revealing the improvement of plant water status.The total porosity of soil and field capacity increases,bulk density and soil infiltration rate decrease after application of Arkadolith,indicating that it has significantly improved soil physical properties.It also can alleviate soil nutrition imbalances by increasing soil nutrient reserves.
