摘要
本研究以7个薄壳山核桃品种为材料,从薄壳山核桃适宜品种选择、授粉树配置改良、低产林品种更新和品种组合优化等方面进行研究。结果表明,波尼品种在抗旱性、果实产量与品质方面表现良好,适宜在皖北地区栽植;采用“波尼+威奇塔+YLC29”3个品种组合配置的栽植方式,可改善主栽品种威奇塔的雌花授粉问题,同时采用高位嫁接授粉品种技术,在减少授粉树栽植的同时,扩大花粉传播半径,提高授粉率。皖北地区薄壳山核桃品种改良与组合优化技术研究可为薄壳山核桃林地的科学管理提供参考,促进该地区薄壳山核桃产业的可持续发展。
Seven varieties of Carya illinoinensis were used to explore the selection of suitable varieties,improvement of pollinating tree configuration,renewal of low-yielding forest varieties and optimization of variety combination.The results showed that Poni variety was good in drought resistance and fruit yield and quality,and was suitable for planting in northern Anhui;the planting method of“Poni+Wichita+YLC29”combination solved the pollination of the main varieties,so as to reduce the tree planting and expand the pollen propagation radius and increase the pollination rate.Through the research on the variety improvement and combination optimization technology of the pecan in northern Anhui,it provided scientific reference for the scientific management of the woodland,and promoted the high quality and sustainable development of the industry in this region.
