摘  要：
[目的]调查2个泡核桃品种初果期的表现,为今后抚育管理提供参考。[方法]分别在腾冲市界头镇南、中、北产区随机抽取9年生的大泡核桃和细香核桃各3株,对其单株产量、基径、树高、综合冠幅、果形指数、单果重和出仁率7个性状进行调查分析。[结果]细香核桃与大泡核桃在界头镇全域内都能正常生长;细香核桃树体生长速度较快,单株产量、出仁率都表现优良;二者坚果形状相似,呈圆形或椭圆形,细香核桃的坚果较大泡核桃小。细香核桃更适应界头中北部较高海拔的气候,而大泡核桃较适应界头南部较低海拔的气候。[结论]应选择细香核桃为界头镇主栽品种,大泡核桃作为补充品种,在局部低海拔地区种植或作为授粉品种种植。

摘  要：
[Objective] To investigate early fruiting performance of two Juglans sigillata varieties and provide a reference for future tending management.[Method] Three strains were randomly chosen from nine years old Dapao and Xixiang walnut at the south,middle and north region of Jietou Town,Tengchong City,respectively. Seven traits were investigated such as yield per plant,basal diameter,tree height,synthetical canopy,fruit shape index,weight of single fruit and kernel percent.[Result]Xixiang and Dapao walnut grew normally at Jietou Town. Xixiang walnut grew faster than Dapao walnut,it had good properties in yield per plant and kernel percent. The shapes of two J. sigillata varieties were similar,round or oval,but Xixiang walnut was relatively smaller than Dapao walnut. Xixiang walnut was more suitable for the climate of high altitude at north and middle region of Jietou Town,when Dapao walnut was more suitable for the climate of low altitude at southern area of Jietou Town.[Conclusion]Xixiang walnut would be chosen as major variety for Jietou Town. Dapao walnut would be chosen as complement variety which planted at local low altitude area or as pollination variety.
