The Effect Of Climate Change On Winter And Spring Wheat Yield In Ningxia

At present,global warming is the most significant feature of climate change,as temperatures gradually warming,the number of rain also appeared different degree of change,the change of planting in winter and spring wheat region,will have a strong impact,and Ningxia area are the most important species is winter,spring wheat.In recent years,the Ningxia region has become a typical area where the temperature is warmer and the amount of rain is decreasing.How will the yield of winter and spring wheat be affected?.Based on this,this article through the winter wheat in Ningxia cost estimates,analysis of the regional climate change under the mode of PRECIS and A2 and B2 in wheat growing period in Ningxia scene of the scene,and the Ningxia wheat yield in future scenarios were simulated.The strategy of coping with climate change in winter and spring wheat in Ningxia was also pointed out,so as to provide a reference for the development of wheat in Ningxia.The main conclusions are as follows:1.analyze the evolution characteristics of spring wheat in the growth season,agricultural climate resources change characteristics of Winter Wheat in the growth season of agricultural climate resources and Ningxia winter and spring wheat in the utilization of agricultural climate resources on different rate,the rise in temperature will reduce the yield of spring wheat,the change of precipitation the winter wheat yield is relatively complex,in general,to shorten the production period of climate change in winter wheat,winter wheat yield decreased.2.analyze the change trend of the average temperature from 2022 to 2050 in the A2 and B2 scenarios: the average temperature in winter shows an upward trend under the A2 and B2 scenarios.The average temperature in spring fluctuates in the two scenarios,but after 2043 to 2045,the temperature fluctuates in the trend of fluctuation.Under the A2 and B2 scenarios,the average temperature of winter and spring was tested by the slip t-test,and the results were basically the same.3.continue to promote stability through the winter wheat planting,to ensure food safety;cultivation of winter wheat varieties of high quality and high yield,improve the yield potential;adjust the irrigation system,develop water-saving cultivation technology and effective strategies to help Ningxia to adapt to climate change in winter wheat.
