摘 要:选取阿拉尔垦区绿洲不同地理位置的枣园土壤为研究对象,采取实地调查结合室内分析方法,以期了解枣园土壤现状,为后续施肥及其他农事生产活动提供参考。结果表明:各试验地土壤容重均为1.36 g/cm 3,属于过紧状态,土壤孔隙度在44.96%~46.35%之间,总体偏小,需要深翻土壤。土壤pH值在8.12~8.24之间,总体偏碱,不利于铵态氮肥的施用,需添加一定的酸性和钙质化肥来缓解土壤性状或建设高效科学的农业排碱设施。土壤表层含水率偏低,在5.93%~14.45%之间,可适当生草、增加供水。枣园土壤全磷含量(1.19~2.45 g/kg)偏高,但土壤全氮含量(0.24~0.81 g/kg)相对较少,为此,建议:适当深施、多施氮肥,由绿洲内部到绿洲边缘需按枣园实际情况逐渐增加氮肥的施用量。The soil of jujube orchards in different geographical locations of oases in Aralken District was selected as the research object,and field investigation combined with indoor analysis methods were adopted to understand the soil status of jujube orchards and provide reference for subsequent fertilization and other agricultural production activities.The results showed that the soil bulk density of each test site was 1.36g/cm 3,which was too tight.The soil porosity was between 44.96%~46.35%,which was small overall,and it was necessary to turn the soil deeply.The soil pH value is between 8.12~8.24;the overall alkali is not conducive to the application of ammonium nitrogen fertilizer,and it is necessary to add certain acidic and calcareous fertilizers to alleviate soil properties or build efficient and scientific agricultural alkali drainage facilities.The water content of the soil surface layer is low,between 5.93%~14.45%,which can properly grow grass and increase water supply.The soil total phosphorus content(1.19~2.45 g/kg)in jujube orchards is high,but the soil total nitrogen content(0.24~0.81 g/kg)is relatively small.It is recommended to apply more nitrogen fertilizer,and gradually increase the application amount of nitrogen fertilizer from the inside to the edge of oasis according to the actual situation of jujube orchard.
