Bibliography: | Ningyu strawberry; polynomial model; yield analysis CAI Weijian, ZHAO Mizhen, WANG Zhuangwei, YU Hongmei(Institute of Horticulture, Jiangsu Academy of Agricultural Sciences, Nanjing 210014, China) 23-1391/S 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. |
