Effect of Climate Conditions on Blueberry in Dandong Open Field
Based on the ground-based meteorological data and the observed data of blueberry phenology from 1991 to 2020,the meteorological indexes of suitable areas for blueberry cultivation in Dandong were compared and analyzed,the effects of temperature,moisture and light on the growth of blueberry were studied,and the meteorological conditions in different counties were analyzed.The results showed that the climate resources of the main growing areas of blueberry in Dandong were good.Besides the low temperature in winter,the climate conditions for the growth of blueberry were basically satisfied.The temperature amplitude of April in 30 years is large,so it is necessary to prevent the influence of spring cold on the blueberry industry,water management needs to be strengthened,while late-maturing varieties need to be protected against disastrous weather condi-tions such as heavy rainfall and even overcast rain.The research results are expected to provide scientific ref-erence for the development of blueberry industry.
