| 摘 要： | 从湖北省大悟县1994—2010年逐年花生产量资料中分离出随气象因素变化的气象产量,分析了花生气象产量率和气温、降水量、日照时数等气象要素的相关关系,并且建立了基于气象因子的大悟县花生产量预测模型。研究表明,播种期热量不足,始花期日照过量是影响花生产量的主要因素;下针期充足热量、适量降水和日照有助于花生增产。夏花生播种的起始气温为22.2°C,始花期日照时数临界值为53.2 h,下针期气温临界值为28.9℃,降水量临界值为45.7 mm,日照时数临界值为83.8 h。

| Abstract: | Based on the 1994-2010 annual peanut production data in Dawu county, the relationship between peanut production and meteorological factor was analyzed, and a forecasting model for peanut production was established based on the meteorological factor. The results show that the peanut production will decreases due to the shortage of heat in seeding period and abundant sunshine in early flowering period. sufficient heat, appropriate precipitation and sunshine in ending flowering period is helpful to improve the peanut production. The sowing temperature for summer peanut is 22.2 ℃, and the critical value of sunshine in early flowering period is 53.2 h. The critical values of air temperature, precipitation and sunshine in ending flowering period are 28.9 ℃, 45.7 mm and 83.8 h respectively. |
