摘要
为了掌握野生欧洲李不同原生分布地土壤养分分布特征,从而为野生欧洲李原生分布地土壤肥力的协调与改善及栽培驯化提供理论依据。在野生欧洲李6处分布地,从14个土壤养分指标分析其不同土层养分含量的分布特征及差异性。结果表明:(1)6处原生分布地土壤p H值为8~8.35,均表现为弱碱性,有机质含量丰富,但全钾含量却远远低于土壤养分分级标准的6级标准参数值。新源交吾托海与西阿克塞分布地0~90 cm土层均表现出磷素供应不足的现象。在0~60 cm土层深度,土壤养分含量大多在新源改良场三队分布地表现较高,在60~90 cm土层深度,土壤养分均在巩留伊力格达依分布地表现较高。(2)除去巩留伊力格达依分布地其余5处分布地有效镁含量均处于肥沃状态,6处原生分布地有效钙含量均处于土壤养分分级2级标准。(3)各分布地土壤养分中各元素间具有不同程度的相关性,土壤养分改善过程中大部分元素具有良好的独立性。综上所述,6处原生分布地不同土层深度土壤养分较丰富但存在不同程度的差异。
In order to understand the distribution characteristics of soil nutrients in different primary distribution areas of wild European plum, it provided the basis for the coordination and improvement of soil fertility and cultivation and domestication of wild Europe plum. The distribution pattern of six soil nutrients in different regions of the soil was analyzed from 14 soil nutrient indicators. Results shows that： （1） The pH value of soils in the six primary distribution sites was 8 to 8.35, all of which were weakly alkaline and had rich organic matter content. However, the total potassium content was far below the standard parameter values of the soil nutrient classification standard. The 0-90cm soil layers of the Xinyuan Jiaowutuohai and Xiaksai areas all showed insufficient supply of phosphorus. At depths of 0-60cm, soil nutrient content was mostly distributed in the three teams of the new source improvement field. At the depth of 60-90cm soil layer, soil nutrients all showed higher distribution in Gongliu Iligedayi. （2） The contents of available magnesium in the remaining five locations in the distribution area of Gongliu Iligedayi were all in fertile state, and the contents of available calcium in the six primary distribution areas were all in Level 2 （medium） standard of soil nutrient grading. （3） There are different degrees of correlation among the elements in soil nutrients in each distribution area, and most of the elements in soil nutrient improvement process have good independence. It is concluded that soil nutrients in different soil depths at the six primary distribution sites are rich, but there are different degrees of difference.
