摘要
【目的】近年来,山西核桃主产区晚霜冻害频发,严重影响了核桃产业的发展。因此,选择适宜山西栽培的避晚霜核桃品种尤为重要。【方法】对山西农业大学果树研究所核桃资源圃各资源结果母枝顶芽及侧芽萌发情况进行了调查,并结合产量、气象数据、物候期对抗晚霜性进行了评价。【结果】对山西农业大学果树研究所核桃资源圃中80份普通核桃种质资源进行冻害调查,筛选出了受冻害影响较小的3个品种‘秋香’‘西岭’‘fh1号’。进一步研究表明,‘秋香’和‘西岭’在山西晋中核桃主产区均表现出较强的避晚霜能力。【结论】‘秋香’和‘西岭’可作为山西晋中地区避晚霜核桃品种进行栽培推广,强调减轻晚霜对区域核桃经济林的危害有重要意义。
【Objective】In recent years,the main walnut producing areas of Shanxi have frequent late frost damage,which has seriously affected the development of walnut industry.Therefore,it is particularly important to choose walnut varieties suitable for cultivation in Shanxi.【Methods】The germination of top buds and lateral buds of the fruit branches of each resource was investigated in the walnut resource orchard of Pomology Institute,Shanxi Agricultural University,and the resistance to late frost was evaluated based on the yield,meteorological data and phenological period.【Results】The freezing damage of 80 common walnut germplasm resources in the walnut resource garden of the Institute of Pomology of Shanxi Agricultural University was investigated,and three germplasms of‘Qiuxiang’,‘Xiling’and‘fh1’were less affected by frost damage.Further research results showed that‘Qiuxiang’and‘Xiling’showed strong ability to avoid night frost in the main walnut planting areas of Jinzhong City,Shanxi Province.【Conclusion】‘Qiuxiang’and‘Xiling’can be cultivated and promoted as late frost walnut cultivars in Jinzhong area of Shanxi,and the study is of great significance to reduce the harm of late frost to regional walnut economic forests.
