摘　　要：为筛选出最适合湘南花生产区的钙肥施用量,以湘花2008为供试品种,根据生石灰(CaO)用量设计0、20、40、60、80和100 kg/667m^(2)6种施钙浓度的大田试验,研究不同施钙量对花生农艺性状、经济性状、商品性状的影响。结果表明:施钙量与花生荚果产量、荚果饱满度和出仁率显著正相关,施钙可以提高花生的荚果产量、荚果饱满度和出仁率,通过数学建模拟合函数求得湘南花生产区的生石灰最佳施用量为121 kg/667m^(2)。In order to choose the most suitable calcium fertilizer application amount for peanut production area in Southern Hunan,six calcium gradient amount treatments (0,300,600,900,1 200 and 1500 kg/hm^(2)CaO) were set under field conditions by using Xianghua 2008as the test cultivar to analysis the effects of different calcium application amounts on agronomic,economic and commercial traits of peanut.The results showed that calcium application amount was significantly positively correlated with peanut pod yield,pod plumpness and kernelyield,and calcium application could improve peanut pod yield,pod plumpness and kernel yield.Through mathematical modeling and fittingthe function,it finds the optimal application amount of quicklime in the production area of peanut in Southern Hunan is 1 815 kg/hm^(2).
