| 摘 要： | 通过对梨树不同品种、不同树龄以及不同立地条件下对晚霜抗性差异的分析表明,不同品种对晚霜抗性有显著差异,老树抗性强于幼树,无防护林果园不同高度的树冠受冻率差异显著,有防护林果园不同高度的树冠受冻率差异不显著,采用立木式和棚架式2种栽培方式的梨树受冻率差异不显著。 |

| Abstract: | Analysis of resistance of pear to late frost on different varieties,tree age and orchard environment was carried out.The results showed that there were some significant differences in the resistance to late frost among the different varieties and age of pear trees.It was also found that degree of injury to pear was influenced by the height of tree crown and protecting belt of orchard.Main factors which result in injury to pear trees by late frost,and methods which can decrease harm of late frost have also been analyzed. |
| Keywords: | Pear tree Late frost Frost injury |
