2013年3月从陕西省大荔县引进‘沾化冬枣’优良接穗,对米脂试验站、子洲县佛堂墕村的‘中阳木枣’‘梨枣’老品种园进行高接换头。经过连续3年的观察,该品种在当地表现良好,早果丰产,嫁接当年株结果率达35%,第2年即可全面挂果,第3年进入丰产期,平均株产10.6kg,每667 m~2产量达1 176.6 kg,且较当地主栽品种‘中阳木枣’‘临猗梨枣’抗病,裂果率下降了65.8%,适合在陕北榆林以南黄土丘陵区生长。高接换头较利用幼苗建园提早2~3年见效益,可实现无公害、优质、高产、高效的生产目标,是‘沾化冬枣’快速建园的好方法,可逐步大面积推广。
In March 2013, the fine scion of ’Zhanhuadongzao’ was introduced from Dali County, Shaanxi Province. The high-quality seedling plant of ’Zhongyang Wood Date’ and ’Lizao’ head. After 3 consecutive years of observation, the variety in the local good performance, early fruit yield, the grafting year results rate of 35%, the second year can be full of fruit, the third year into the high yield, the average yield of 10.6kg, 667 per 667 The yield of m ~ 2 reached 1 176.6 kg, which was 65.8% lower than that of the local cultivars ’Zhongyao jujube’ and ’Linli lizao’. It was suitable for growth in the loess hilly area of northern Yulin in northern Shaanxi. High take over than the use of seedlings built garden benefits 2 to 3 years earlier, to achieve pollution-free, high quality, high yield and efficient production targets, ’Zhanhuadongzao’ a quick way to build a good garden, can be gradually large-scale promotion.
