摘要
成花坐果是影响薄壳山核桃高产稳产的关键。通过整理相关文献,总结了薄壳山核桃开花结实的物候期,阐明了其成花坐果的主要机理、影响因素以及导致落花落果的原因,并从合理配置授粉树种、修剪整形、施用植物生长调节剂、防治病虫害、加强土水肥管理等方面提出了促进成花坐果的主要措施,并指出薄壳山核桃成花坐果的分子机理将是今后的研究重点。
The flowering and fruit-setting rates are the key indicators affecting the high and stable yield of Carya illinoensis.Through collation for domestic and foreign literature,this paper has introduced the flowering and setting fruit phenophase of Carya illinoensis,elaborated the main machanisim and factors affecting flowering and fruit-setting as well as the causes resulting in flower and fruit dropping,and put forward the major measures of promoting flowering and fruit setting from the aspects of appropriate matching of pollinizers,pruning and shaping,applying plant growth regulators,controlling disease and insect pests,and enhancing fertilizer and water management.
