野生欧洲李根蘖苗自然分布规律研究

The Study on the Natural Distribution Law of Root Sucker for the Wild European Plum

【目的】掌握野生欧洲李的无性繁殖特性,调查两个自然分布区的野生欧洲李植株及其根蘖苗的分布特征。【方法】采用实地样方调查法对野生欧洲李植株数量、树龄及其根蘖苗的数量与分布区域进行调查统计分析。【结果】野生欧洲李在新源博尔赛与巩留伊力格代的分布面积分别为3 131.4和3 784.95 m2,成龄树分别有131和30株,共有170株,根蘖苗分别为4 443和2 739株。平均每株成龄树有57株根蘖苗,根蘖苗一般分布在母株4 m范围内,最远可达7 m。【结论】野生欧洲李在两个主要分布区的分布面积大约为7 000m2,共有成龄株和根蘖苗7 400株;根蘖苗数量最多的为II级,其次为I级和III级;成龄株的数量、分布与根蘖苗的数量、分布密切相关。

[Objective] In order to understand the vegetative propagation of the wild European Plum in the state of nature,this investigation aims to surveyed the distribution characteristics and its root sucker in two natural ranges for the wild European Plum.[Method] The distribution characteristics,age and quantity of the mature tree of wild European Plum were investigated and statistical analyzed statistically by field investigation,and the distribution characteristics and quantity of the root sucker were studied by field investigation,too.[Result]The distribution areas of the wild European Plum is were respectively 3,131.4 m2 and 3,784.95 m2 in Boersai,Xinyuan County and Yiligedai,Gongliu County.The quantity numbers of the mature tree was wererespectively 131 and 30,respectively and the root suckers was were 4,443 and 2,739,respectively.A mature of tree,had have 57 root suckers.usually distribution in 4 m distance of mature tree,and furthest distance was 7 m.[Conclusion]The distribution area of the wild European Plum was about 7 000 m2,and the number of the mature tree and root sucker were totally 7400,which belonged to grade Ⅱ,followed by Grade Ⅰ and Ⅲ.The number and distribution of the mature trees were positively related to the number and distribution of the offspring.
