| 摘 要： | 通过对苹果树休眠枝条含水量的比较研究,探讨了黄土高原沟壑区不同地形、不同农艺措施处理对果树枝条受冻害“抽干”程度的影响。结果表明,沟坡地形热量状况最好、果树受冻害程度最轻,台坪次之,塬面受冻害程度最重;生育期灌溉和果园深翻可以明显降低枝条受冻害程度。

| Abstract: | Study was conducted with the young trees of Qinguan variety planted on the different land features in loess plateau region and treated with or without irrigation and deep dig. Water con-tent and winter freezing injury of the dormant branch (consisting of spring and autumn shoot) were measured . Results showed there was less winter freezing injury for the trees grown on the wide terrace , and the irrigating in the growing season and deep dig of the soil could reduce the win-ter freezing injury. |
