静宁县核桃适栽品种筛选及应用

Screening and Application of Suitable Walnut Cltivar in Jingning County

核桃是静宁县大力发展的经济林树种,种植品种众多,不同品种性状各异,由于品种本身特性的差异、环境因素的影响、栽培技术的不同,使各个品种表现出品质的优劣、抗性的差异。因而根据种植区域的不同,选择抗逆性强、进入结果期早、结果能力高、品质优良、耐粗放管理的品种种植是提升核桃种植效益、促进核桃产业快速健康可持续发展的重要环节之一。为此,2011-2015年对静宁县引种栽培的7个核桃品种进行了有关抗性、结果性状及品质的调查,结果表明:在适宜种植区,香玲、鲁光、西扶1号、陕核1号、辽核1号、薄壳香、温185均可种植;在能种植区可选择抗寒性强的薄壳香、辽核1号、温185种植,以减轻冻害给生产造成的损失;在边缘区则应以种植温185为主,以避免抗寒性差的品种因越界种植出现死树死枝现象,而影响产业的发展。

Walnut is a kind of economic forest tree which is vigorously developed in Jingning County.There are many culitivars and different cultivars have different characteristics.Due to the differences characteristics,environmental factors and cultivation techniques,various cultivars show differences in quality and resistance.Therefore,according to the different planting areas,selecting cultivars with strong resistance,early fruiting period,high fruiting ability,good quality and extensive management resistance are the important links to improve walnut planting efficiency and promote the rapid,healthy and sustainable development of walnut industry.Therefore,the resistance,fruit traits and quality of seven walnut cultivars introduced and cultivated in Jingning County from 2011 to 2015 were investigated.The results showed that Xiangling,Luguang,Xifu 1,Shanhe.1,Liaohe.1,Bokexiang and Wen185 could be planted in suitable planting areas.The cultivars of Bokexiang,Liaohe 1 and Wen 185 with strong cold resistance can be selected for planting to reduce the loss caused by freezing injury.In the other areas,Wen 185 should be choosen for avoiding poor cold resistance cultivars.
