摘　　要：以草莓新品种宁玉为试验材料,利用多项式模型拟合其产量变化规律。结果表明,宁玉在138 d采果期内,产量达到27 336.0 kg·hm-2,呈双"S"型增长;利用六次多项式拟合其产量变化,拟合精度达到0.998,效果显著;单位时间产量呈典型的双峰型,平均日产量为198.0 kg·hm-2,最高日产量为295.5 kg·hm-2;果实收获呈现出明显的两个批次,其中第一批果实产量比例高。Ningyu, a new strawberry cultivar, was used as the experimental material to analyse its yield variation fitted by polynomial model. The results showed that the yield increase followed double ＇S＇- shaped curve and the total yield reached 27 336.0 kg. hm2 during 138 d of fruit picking season of Ningyu. It was significant to use six polynomial fitting yield of Ningyu, which got fitting precision of 0.998. Yield per unit time of Ningyu showed a typical bimodal curve. Ningyu strawberry had the average daily yield of 198.0 kg. hm2 and the maximum daily yield of 295.5 kg. hm-2. There were two obvious batches of fruit ripening during fruit picking season of Ningyu, and the first batch had a higher ratio of yield.
