为找到浙江龙游地区红肉蜜柚高接换种的良好中间砧,在椪柑、夏红桔柚、甜春桔柚和香抛等4种中间砧上高接红肉蜜柚后,对高接树的生长结果表现、适应性、果实品质等进行观测比较。结果表明,高接树的抗寒性明显增强,冬季极端最低气温≤-5.5℃的情况下,成年树冻害为1~2级,露地栽培可以正常结果。香抛、夏红桔柚、甜春桔柚高接红肉蜜柚的接口表现略好于椪柑。夏红桔柚高接红肉蜜柚的丰产性和果实品质均较好;香抛高接红肉蜜柚的丰产性较好,果实品质一般;椪柑高接红肉蜜柚的丰产性最好,果实品质稍差,需注意通过科学的管理提高品质;甜春桔柚高接红肉蜜柚的丰产性较差,果实品质一般。
In order to find a good intermediate anvil for the high yield of red meat pomelo in Longyou of Zhejiang Province, after the red meat pomelo was picked on four kinds of anvil, such as ponkan mandarin, summer red orange pomelo, sweet spring pomelo and fragrant tonic, Growth performance, adaptability, fruit quality and so on. The results showed that the cold hardiness of G. taiwanensis was significantly enhanced. In winter, when the extreme minimum temperature was ≤ -5.5 ℃, the frost damage of adult trees was from 1 to 2, and the cultivation in open field could be normal. Hong throw, summer red orange grapefruit, sweet red grapefruit high pick red meat pomelo interface performance slightly better than ponkan. The yield and fruit quality of summer red orange grapefruit high take red meat pomelo are better; the high yield of sweet red grapefruit followed by red meat pomelo is better; the fruit quality is generally; The quality of a bit poor, should pay attention to improve the quality of scientific management; sweet spring grapefruit high pick red meat pomelo poor yield, fruit quality in general.
