摘要
[目的]筛选大理低海拔地区规模化发展生态抗逆性强的优良核桃品种.[方法]采用群众荐优和实地调查相结合的方法,对云南大理低海拔地区188棵不同树龄(不小于15 a)的核桃树进行调查.[结果]经预选、初选、复选和决选,最终选出3株低海拔地区生态抗逆性核桃优良单株.单果重为7.6～10.3 9,壳厚为0.73～0.96 mm,出仁率为51.09％ ～ 62.46％.各决选优株果实成熟期较漾濞大泡核桃早.[结论]核桃品种表现为成熟早这一价值特性,在大理低海拔核桃生产中有较高的推广应用价值.
Abstract
[Objective] Select of superior walnut varieties with high ecological stress resistance in Dali.[Method] The 188 trees of different ages (not less than 15 a) of the walnut tree in Dali of Yunnan were surveyed by method of the people commend and on-the-spot investigation.[Result] Ultimately selected 3 trees of ecological resistance in low altitude areas of walnut fine plant though qualifying,the primaries,check and runoff.The fruit weight was 7.6-10.3 g,the shell thickness was 0.73-0.96 mm,kernel rate was 51.09％-62.46％.The runoff superior trees of fruit maturity than the Yangbi bullae early.[Result] Walnut varieties showed the value of early maturity,which has a high value in the promotion of low altitude walnut production in Dali.
