| 中文摘要: |
| 冻害是柑桔北缘产区主要自然灾害之一。2018年1月湖北省当阳市先后经历了两次较强雨雪霜冻天气过程,部分柑桔园出现不同程度的落叶及枝稍枯死现象。对当年产量和经济效益产生了一定影响。实地调查发现柑桔冻害程度除了与品种、树龄、树势等有关外,不同立地条件对柑桔冻害的发生也有较大影响。掌握这些规律对于指导柑桔园地选择及高标准建园具有一定的意义。 |
| 英文摘要: |
| Freezing damage is one of the major natural disasters in the northern region of citrus production. In January 2018, the city of Dangyang, Hubei Province,experienced two strong rain, snow, and frost weather processes. Citrus showed varying degrees of deciduous and dead leaves. As a result,the productions and economic benefits of this year had been influenced。By field surveys we found that, it was not only tree species, tree age, tree vigor, etc,but also different site conditions thatcouldhave a greater impact on the occurrence of citrus frost damage. Grasping these laws has a certain significance for guiding the choice of citrus gardens and the establishment of high-standard orchards. |
