甘肃河西走廊酿酒葡萄晚霜冻害对葡萄品质的影响及预防措施
Effect of Late Frost on Wine Grape Quality and Preventive Measures in the Hexi Corridor of Gansu Province

针对甘肃河西走廊晚霜冻害严重的状况，研究晚霜冻害对酿酒葡萄品质的影响，分析并提出最佳预防措施，以减少晚霜冻害对葡萄产业带来的损失。通过对10多年葡萄晚霜冻害预防实践经验的总结，分析比较采取预防措施和未采取预防取措施条件下果实感官品质。结果表明，点明火并结合烟熏这一综合预防措施不仅可以有效预防晚霜冻害，经济节约，同时，采取这一措施后葡萄园产量基本未受冻害影响，与果实品质紧密相关的含糖量、单宁较其他措施有大幅度提高，同时果实感官评价得分较高。研究得出对甘肃河西走廊地区葡萄晚霜冻害预防经济有效的最佳措施，克服了目前晚霜冻害给该地区葡萄产业发展带来的制约，以进一步利用该地区得天独厚的自然条件，规模化发展葡萄种植。同时，为不同气候条件下，葡萄产区晚霜冻害的预防提供了成功经验和理论基础。
In order to study the effect of late frost on wine grape quality and analysis the best preventive measures to reduce frost damage to grape industry, the paper summarized the experience of grape frost prevention for more than 10 years, and compared fruit quality of wine grapes with or without frost-preventive measures. The result showed that a comprehensive measure of firing plus smoking is an economic and effective comprehensive measure to prevent frost damage. At the same time, the contents of fruit sugar and tannin, which closely related to fruit quality, increases greatly compared with other measures, and sensory evaluation score of fruit is high as well. So, the economic and effective measures for grape frost prevention in Gansu Hexi Corridor region proposed will be helpful to overcome the currently constraints of frost damage to the development of grape industry in the region, and can be referred for the prevention of frost damage in different climate conditions.
