摘  要:
广西忻城县岩溶石山土壤具有土层浅薄贫瘠、保水性差、易干旱等特点。本试验选用高效农林保水剂、农作物果树抗旱保水剂、稷丰保水剂和旱宝贝MP-3005四种保水剂在移栽金银花扦插苗时施用,探讨了它们对忻城石山土壤物理性状及金银花生长的影响。结果表明:施用保水剂能降低土壤容重,提高土壤总孔隙度和毛管孔隙度,改良土壤结构,从而提高石山土壤持水能力;在石山土壤干旱时,高效农林、旱宝贝MP-3005两种保水剂能够促进金银花二级分枝生长,提高金银花幼苗存活率,保持金银花长势良好,有助于治理荒漠化石山和改善石山地区生态环境。

摘  要:
The soil of karst tor in Xincheng County of Guangxi Province has the characteristics of thin and infertile soil,poor water retention and frequent drought.The paper selects four kind of water absorbents of Agroforestry Absorbent Polymer(AAP),NSAP Hi-swell,Jifeng,and MP-3005 during transplanting Lonicera japonica cutting seedlings and studies the influence to the physiochemical properties of soil and the growth of Lonicera japonica in Xincheng County.The outcomes show that a) applying water absorbent can reduce soil bulk density,and increase total porosity and capillary porosity,and improve the soil structure,and increase the moisture holding capacity of soil;b) under the condition of soil drought,AAP and MP-3005 can promote the growth of secondary branch,increase the survival rate of seedlings,ensure good growth of Lonicera japonica and contribute to the treatment of desertification and improve the ecological environment of tor region.
