本文分析比较了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,对冬植甘蔗新台精1号的生长模型进行拟会,得到株高的最佳生长模型为：模型的拟会精度高、适用性强,可在儋州蔗区应用。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,生点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。从而为蔗园生态系统的定时量调控提供了可靠的理论依据。 In this paper, we compared and analyzed seven commonly used univariate growth models. Using Marquardt’s iterative method of non-linear least squares to solve the model parameters simultaneously, the growth model of winter planting sugarcane Xintaijing No.1 was simulated to obtain the optimal growth of plant height The model is as follows: The proposed model will have high accuracy and applicability and can be applied in Qiongzhou sugarcane area. The results of model analysis showed that sugarcane began to enter the rapid growing stage 94 days after planting (late April), and the fastest point of birth occurred at 157 days after planting (late June) and 233 days after planting (mid September) Process maturity. Which provides a reliable theoretical basis for regulating the amount of sugarcane ecosystem.
