摘　　要：为给陕西省平欧杂种榛引种栽植提供依据和参考,在陕西省主要地理与气候环境区,分别选择代表性强的地域进行了5个平欧杂种榛优良品种引进和栽植试验,结果表明:(1)引种的5个平欧杂种榛品种在三个试验区的成活率从高到低顺序为:眉县>宁陕县>南泥湾林场,“辽榛7号”“玉坠”栽植成活率都超过90%,从栽植成活率指标看,5个品种都适于在秦岭北麓眉县栽植,秦岭腹地宁陕县除“达维”外的其它4个品种都可栽植,在陕北黄土高原南泥湾只有“玉坠”“辽榛7号”可栽植。(2)5个品种在3个试验点都可完成生命周期,品种间生育期差别较小,在眉县生育期250 d左右,3月初芽膨大,4月下旬至5月上旬挂果,8月上中旬果实成熟。(3)在眉县“辽榛8号”栽植后第三年开始挂果,其它品种第四年开始挂果,单株产量“辽榛8号”“达维”“玉坠”相对较高。(4)陕西省平欧杂种榛栽植品种优先选择秦岭腹地是“辽榛8号”“玉坠”,秦岭北坡是“辽榛8号”“玉坠”和“达维”,延安黄土高原是“玉坠”和“辽榛7号”。The survival rate,growth increment,phenological period and other growth conditions of five main varieties(lines)of Corylus hesterophylla×C.avellana were preliminarily analyzed and evaluated after introduction to Shaanxi.The results showed that:(1)The order of the survival rate of five introduced hybrid hazelnut varieties in the three experimental areas from high to low was Meixian>Ningshan>Nanniwan Forest Farm,and the variety Liaozhen No.7 had the highest survival rate;(2)all the varieties completed their growth periods in the three experiment areas.In Meixian County,the growth periods last for around 250 d,with budding in March,bearing fruits in late April and early May and fruit ripening in August;(3)in Meixian Liaozhen No.8 began to bear fruits three years after planting,whereas the other varieties four years after planting.Liaozhen No.8,Dawei and Yuzhui had higher yield of fruits;(4)five different varieties(lines)of Corylus hesterophylla×C.avellana grew well after introduction to Shaanxi,which could preliminarily adapt to the natural climate and other conditions in Shaanxi,with Liaozhen No.8 and Yuzhui well adapted to Qinling Mountains,and Liaozhen No.8,Yuzhui and Dawei well adapted to the north slope of Qinling Mountains,and Liaozhen No.7 and Yuzhui also well adapted to loess plateau area.
