摘　　要：根据《云南省核桃栽培区划研究工作与调查方案》,于2015—2016年在云南省玉溪市选取新平、华宁、峨山3个县11个乡(镇、街道办)具有代表性的142株核桃标准树开展栽培区划研究。初步结果表明,玉溪市核桃主要栽培品种为华宁大白壳核桃、大砂壳核桃等,现有核桃面积10.21万hm^2,其中投产1.85万hm^2,产量866.47万kg,产值204亿元。核桃产量影响因素分析结果表明,海拔、坡向、土壤条件、品种、树龄、管理水平、病虫害、霜冻灾害等均对核桃产量有显著影响,海拔1 700~2 100 m地段为核桃最适宜栽培区。According to the Research and Survey Plan of Walnut Cultivating Regionalization in Yunnan Province,the representative 142 walnut standard trees in 11 townships（ towns,subdistrict offices） of Xinping,Huaning,Eshan were selected from 2015 to 2016. The preliminary results showed that the main cultivated varieties in Yuxi City were Juglans sigillata ＂Huaningbaike＂and ＂Dashake＂and the existing cultivated area was 102 100 hm^2 which included the production of 18 500 hm^2,the yield of8. 664 7 million kg,the output value of 20. 4 billion yuan. Altitude,slope direction,soil condition,varieties,tree age,management level,insect damage and frost disaster had significant effects on walnut production,such as the altitude of 1 700 ~ 2 100 m was the most suitable cultivation area for walnut.
