摘要
为探究承德市围场县沙荒地和河滩地两种不同立地条件下土壤对宇璐沙棘生长及果实品质的影响,对沙荒地和河滩地上生长的宇璐沙棘的生长情况、果实品质及其土壤理化性质进行了测定.结果显示:与沙荒地相比,河滩地宇璐沙棘的株高、地径、活枝数、当年生枝生长量明显提高,河滩地的宇璐沙棘长势壮;河滩地宇璐沙棘果实产量显著高于沙荒地,果实营养成分低于沙荒地;河滩地的土壤含水率、pH、毛管持水量、毛管孔隙度等指标均高于沙荒地,但土壤有机质含量、速效磷含量和碱解氮含量显著低于沙荒地.研究结果为宇璐沙棘标准化生产和管理提供参考.
Abstract
In order to investigate the effects of soil physicochemical properties on the growth and fruit quality of Hippophae rhamnoides'Yulu'under two different site conditions in Weichang County,Chengde City.The growth,fruit indexes and soil physical and chemical properties of Hippophae rhamnoides'Yulu'growing on sand and flood land were determined.The results showed that compared with sand wasteland,wasteland indicators suchas plant height,ground diameter and number of live branches of Hippophae rhamnoides'Yulu'were significantly increased in flood land,the growth of Hippophae rhamnoides'Yulu'was strorger.The yield of Hippophae rhamnoides'Yulu'was significantly higher than that of sand wasteland,and the nutrient was lower than that of sand wasteland.The soil moisture content,pH,capillary water capacity and capillary porosity of the flood land were higher than those of the sand wasteland,but the soil organic matter content,available phosphorus content and alkali-hydrolyzed nitrogen content were significantly lower than those of the sand wasteland.The results of this study can provide reference for the standardized production and management of Hippophae rhamnoides'Yulu'.
