Integrated application of key technology for prevention and control of frost freezing damage during pear blooming period

Abstract：In main pear-growing areas in China, the frost freezing damage during pear blooming period takes place frequently and causes certain loss to different extents, making also a severe challenge to the effective anti-frost management.At present, there are many preventive measures that have been used in the fight against frost freezing damage during pear blooming period, but it is still extremely difficult for researchers and growers to choose from them the appropriate ones or even a set of combination of techniques.In this article, the key techniques and integrated application suitable for different freezing conditions are suggested based on the current anti-frost researches, equipment development and actual preventive practice, so as to provide valuable reference for pear production.
