摘要
红薯是我国四大粮食作物之一,品种较多,分布广泛,产量较高,也是重要的新型能源用作物,具有良好的保健作用。然而,气象条件等环境因素对红薯的产量和品质有较大的影响,为探究各类气象因子对尖草坪区红薯产量的影响,利用太原市尖草坪区气象局所辖站点所观测尖草坪区近43年逐日气象数据,结合尖草坪区红薯生长、发育和产量情况,采用相关性分析的方法,研究了影响尖草坪区红薯生长的主要气象条件,分析表明:红薯生长的关键气象因子是尖草坪区5-10月份平均10 cm地温、6-9月份平均气温、9-10月份合计日照、7-10月份合计降水量,利用多元线性回归的方法建立了以上气象条件与红薯产量的定量模型。根据模型提出了相应的农事建议,对提高当地红薯的产量和质量,实现农业增收,农民增效有重要深远的意义。
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 potatoes 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 District 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 meteorological conditions and the yield of sweet potato were established by using the method of multiple linear regression.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.
