山西省文水县苍尔会山杏种源选育研究

Study on Provenance Breeding of Prunus Davidiana of Cangerhui in Wenshui County of Shanxi Province

笔者介绍了文水县苍尔会山杏种源的选育过程。在同等立地条件下,选择文水县苍尔会乡、交城县东坡底乡、方山县圪洞镇3个山杏种源,分别在方山县圪洞镇、交城县东坡底乡、古交市常安乡进行区试点造林对比试验。结果发现,文水县苍尔会乡山杏种源苗木成活率、生长量及抗逆性都明显优于其他种源苗木。文水县苍尔会乡山杏种源有很强的耐盐碱能力,可以适应多种土壤类型;分枝能力强,单株产种量2 kg/a~3 kg/a。

The breeding process of Prunus davidiana of Cangerhui in Wenshui County of Shanxi Province was introduced in this study.Under the same site conditions,3 Prunus davidiana provenance including Cangerhui Township in Wenshui County,Dongpodi Township in Jiaocheng County and Gedong Town in Fangshan County were selected for pilot afforestation comparative tests in Gedong Town of Fangshan County,Dongpodi Township of Jiaocheng County and Changan Township of Gujiao.The results showed that the survival rate,growth and stress resistance of Prunus davidiana seedlings from Cangerhui provenance in Wenshui County were significantly better than those from other provenances.The Prunus davidiana from Cangerhui provenance in Wenshui County had a strong ability of salt tolerance and could adapt to a variety of soil type.It had strong branching ability and with a single plant yield of 2 kg/a~3 kg/a.
