Effect of Climate Change on Yield of Main Crops in Fuyang Area
Using the daily precipitation, temperature and sunshine data of Fuyang City during 1986-1505, the trend of climate change was analyzed.Taking the main crop winter wheat as an example, the effect of climate change on crop yield in this area was analyzed,and the countermeasures were put forward to address the climate change in agricultural field.The results showed that the heat resources in Fuyang area was increased in the past 30 years, but the precipitation and sunshine hours were decreased slightly.The distribution of precipitation was uneven, especially the amount of precipitation at jointing and booting stage was the limiting factor of winter wheat yield.The increase of ≥10 ℃ accumulated temperature in overwintering period would help the winter wheat safety winter, but also increase the population density, which would lead to the increase of pests and diseases and the spread of weeds.We should respond to the adverse effects of climate change on crops from the aspects of adjusting the planting system, strengthening new varieties breeding, strengthening agriculture meteorological disaster prevention, strengthening agricultural infrastructure construction and so on.
