晋西沿黄枣区新引入制干品种的试验研究

为改变晋西沿黄枣区制干枣品种单一、品质较差的状况，筛选出适宜该枣区栽培的优良制干枣品种，以引入到该枣区的12个制干枣品种为研究对象，对各品种的主要物候特性、树体生长结果表现、单株产量、抗裂性、抗缩果病性和果实品质进行了观测分析。结果表明，临黄1号、圆铃枣、相枣、赞皇大枣、陕北长枣、方木枣和木枣抗裂1号等7个品种能较好地适应该枣区的气候和土壤条件，丰产性较好，制干品质优良，并且具有较强的抗裂性和抗缩果病性，与该枣区主栽品种中阳木枣和保德油枣相比，具有明显的综合优势，可以作为替代品种进行栽培推广。

Experimental Study on Newly Introduced Dried-jujube Varieties to the Jujube Cultivation Region of Western Shanxi along the Yellow River

In order to change the singleness of dried-jujube cultivar and poor quality in the jujube production region of western Shanxi along the Yellow River,to screen the excellent varieties of dried-jujube suited to cultivation in the area,12 Chinese dried-jujube cultivars were introduced into the jujube cultivation area.The main phonological characters,performance of growth and fruiting,yield per tree,resistance to fruit cracking and fruit brown cortex and fruit quality characteristics of the cultivars were observed and analyzed.Compared with the control varieties of “Zhongyangmuzao” and “Baodeyouzao”,seven cultivars among 12 were found to adapt to the climate and site conditions of the introduced area,including “Linhuang No.1”,“Yuanlingzao”,“Xiangzao”,“Zanhuangdazao”,“Shaanbeichangzao”,“Fangmuzao” and “Muzaokanglie No.1”.They had obvious comprehensive advantages in yielding ability,good quality of dried fruit and strong resistance to cracking and fruit brown cortex,indicating that they could be used as the main cultivars for dry-jujube production in the area instead of “Zhongyangmuzao” and “Baodeyouzao”.
