2018年石家庄藁城区果树花期冻害调查

Investigation on Cold Damage of Fruit Trees in flowering phase in Gaocheng District,Shijiazhuang City in 2018

2018年4月上旬,河北省中南部地区出现大风降温天气,此期正值大部分果树萌芽、开花期。这次大风降温导致部分果树遭受了不同程度的冻害,部分果园受冻严重,甚至绝产。为了摸清冻害的发生程度,我们对石家庄市藁城区的部分果园进行了调查。结果表明,不同的栽植地理条件、不同树种、不同品种、不同花期之间,其抗冻能力存在着很大的差异。在选建新园时,要综合考虑以上这些因素,科学合理选择园址。当果树花期出现降温天气时,要采取必要的预防措施。

In early April,2018,there was a strong wind and cold weather in the central and southern Hebei province,which coincided with the budding and flowering of most fruit trees.The cold wind caused some fruit trees to suffer from different degrees of frostbite,and some fruit orchards were severely frozen or even extinct.In order to find out the extent of frostbite,we investigated some orchards in Gaocheng district of Shijiazhuang city.The results show that there are great differences in frost resistance between different planting geographical conditions,different species,different varieties and different flowering periods.When selecting and building a new garden,we should take into account the above factors and choose the site scientifically and reasonably.When the temperature drops during the flowering period,necessary preventive measures should be taken.
