分析比较7种常用的一元生长模型，采用非线性最小二乘法的Marquardt迭代同步求解模型参数的方法，对冬植甘蔗新台糖1号的生长模型进行拟合，得到株高的最佳生长模型为：模型的拟合精度高、适用性强，可在儋州市那大镇附近蔗区应用（其他地区可作参考）。经模型性质分析，得出植后94d（4月下旬）甘蔗开始进入快速生长期，生长速度最快出现在植后157d（6月下旬），植后233d（9月中旬）甘蔗开始进入工艺成熟期。
Seven commonly used univariate growth models were analyzed and compared. The Marquardt iterative method of non-linear least squares was used to solve the model parameters simultaneously. The growth model of winter sugar cane Xintai 1 was fitted and the optimal growth model of plant height : Model fitting accuracy, applicability, can be used in the vicinity of the town of Danzhou that Cane applied (other areas can be used as a reference). The results showed that sugarcane began to enter the rapid growing stage 94 days after planting (late April), and the fastest growth appeared at 157 days after planting (late June) and 233 days after planting (mid September) period.
