Effects of Arkadolith Soil Modifier on Sand Soil＇s Properties and Growth of Astragalus Mongolicum
摘要
Abstract
To find out the amelioration effect of Arkadolith,a new soil modifier on sandy soil physical and chemical properties and the growth of Astragalus mongolicum,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 of Astragalus mongolicum,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.关键词
