Study on the Influence of Meteorological Conditions on Sweet Potato Yield in Jiancaoping District
Sweet potato is one of the four major food crops in China.It has many varieties,wide distribution and high yield.However,environmental factors such as meteorological conditions have a greater impact on the yield and quality of sweet potatoes.To explore the impact of various meteorological factors on the yield of sweet pota-toes in Jiancaoping District,based on the daily meteorological data of Jiancaoping District for the past 43 years,the growth,development and yield of sweet potato in Jiancaoping District,China,were analyzed by the method of correlation analysis.The main meteorological conditions affecting the growth of sweet potato in Jiancaoping Dis-trict were studied.The key meteorological factors for sweet potato growth in Jiancaoping District are the average temperature of 10 cm from May to October,the average temperature of June to September,the total sunshine from September to October,and the total precipitation from July to October.The quantitative models of the meteoro-logical conditions and the yield of sweet potato were established by using the method of multiple linear regres-sion.According to the model,the corresponding agricultural suggestions are put forward,which have far-reaching significance to improve the yield and quality of local sweet potato,to increase agricultural income and to increase the efficiency of farmers.
