Abstract: Based on the data of temperature, precipitation, sunshine, yield, growth period and yield structure of potato in Songnen Plain of Heilongjiang Province from 1971 to 2017,Authors analyzed the effects of climate change on potato growth and yield, It also find out the significant meteorological factors in different developmental stages. It should provide scientific basis for disaster prevention and mitigation of potato production. The main conclusions are as follows: In Songnen Plain, the whole growth period of potato was extended 1987-2017, sowing time advanced and delayed later, emergence stage is advanced, branching and inflorescence formation and flowering advanced and delayed later, the harvest fluctuates frequently, accumulated temperature increased, yield was on the rise. There was little correlation between the rate of small potato and meteorological factors in each stage of development.
