| 摘要: |
| 以洛川富士苹果为对象，研究了苹果在临界损伤高度以下，跌落高度对其贮藏时间的影响。采用自制跌落试验系统，测试了苹果在临界损伤高度下不同高度跌落后的硬度及贮藏时间，统计分析了苹果跌落高度对其硬度及储贮时间的影响。结果表明：在临界高度以下，苹果不会出现现时损伤，但其贮藏时间会缩短；跌落高度越高，贮藏时间缩短越明显。 |

| Abstract: |
| The influence of drop heights on apple's storage life was studied using Luochuan fushi apple as samples. The apples were dropped using the drop test system made by ourselves. The hardness and storage life of apples after drop in different drop heights were tested under below critical drop height. The data were analyzed with statistics method. The results showed that apple does not bruise under below critical; the storage life of apples is shortened after dropped; the storage life of apples decreases with drop height. |
| Key words: drop critical drop height apple storage period |
