| 摘 要： | 为了解2020/2021年寒害对贵州芒果主产区主栽品种的影响，促进贵州芒果的产业结构调整，于2021年2月基于不同产区、品种、海拔高度对贵州芒果主产区芒果冬季寒害受害情况进行了调查。结果表明，基于产区，望谟地区受寒害程度较轻，贞丰地区受害程度最重。基于品种，金煌芒抗寒性较好，凯特芒抗寒性较差。基于海拔，凯特芒随海拔高度升高寒害指数明显升高，金煌芒随着海拔高度升高寒害指数无明显提高。贞丰产区为寒害重灾区，应调整产业结构，种植抗寒性高的芒果品种，并加大防寒投入，以减少寒害带来的影响。

Investigations on chilling injury of Mountainous Mango in Guizhou in 2020/2021 |
| |
| Abstract: | In order to find out the damage of chilling injury in 2020/2021 on major mango cultivars of main producing areas in Guizhou, to promote the mango industrial structure adjustment, the effect of cold injury on main mango cultivars was investigated in different producing areas and latitudes. Experiment results showed that among three main producing areas, the damage degree in Wangmo was the lightest , and the damage degree in Zhenfeng was the heaviest; among mango cultivars, the cold resistance of Jinhuang was best, the cold resistance of Kaite was worst; the chilling damage indexes of Kaite increased significantly with latitude, those of Jinghuang had no significant increase. Zhenfeng producing area was a heavy disaster area, industrial structure adjustment should be progressed, high cold resistance cultivars should be planted, and the investment of cold protection should be increased, to reduce the effect of chilling injury on mango. |
