玉溪市大豆种植气候条件分析及生产潜力研究

Research on Production Potential and Analysis of Climatic Conditions of Soybean Planting in Yuxi City

为充分利用气候资源,挖掘玉溪市大豆生产潜力,文章以玉溪市9个不同海拔高度大豆主栽区域为研究对象,探讨大豆种植气候条件及生产潜力。结果表明,玉溪市大豆主栽区的日照时数、平均气温、降雨量、太阳总辐射量等气候条件适宜大豆生长,但存在春作降雨量不足,夏秋作降雨量过多问题。运用温度、降水、蒸散等指标测算玉溪市大豆气候资源利用率为0.646,表明玉溪市大豆生产上光、热、水资源的可利用潜力较大。通过提出玉溪市大豆高产栽培技术措施,助力玉溪市大豆产业发展。

In order to make full use of climate resources and tap the potential of soybean production in Yuxi City,Nine different altitudes soybean planting areas in Yuxi City were taken as the research object,the climatic conditions and production potential of soybean planting were explored.The results showed that the climatic conditions such as sunshine hours,average temperature,rainfall and total solar radiation in the main soybean planting area of Yuxi City were suitable for soybean growth,but there were also some problems,such as insufficient rainfall in spring and excessive rainfall in summer and autumn.Using temperature,precipitation,evapotranspiration and other indicators,the utilization rate of soybean climate resources in Yuxi City was 0.646,which indicating that the utilization potential of light,heat and water resources in soybean production in Yuxi City was great.The technology measures of high-yield cultivation measures of soybean were put forward to help the development of soybean industry in Yuxi City.
