根据杨梅发育对光温的反应过程,利用不同的地点、年份和品种试验资料,建立了以光温效应(Photo-thermal effectiveness,PTE)为尺度参数的杨梅生育期模拟模型,并运用独立的数据对其进行验证。结果表明,模型对杨梅雌花序出现、雌花开放、展叶、坐果、果实成熟等生育期所需天数的模拟值与实测值之间的回归估计标准误差(RMSE)分别为2.51、1.83、2.68、2.70和2.45 d;与以有效积温法(RMSE分别为8.02、7.81、5.46、5.40和11.83 d)和PAR日积分法(RMSE分别为8.28、11.0、8.52、5.56和6.87 d)为尺度的发育模型相比,模拟精度分别提高了8.6%和10.2%。
According to the reaction process of Yangmei development to light temperature and temperature, the simulation model of Yangmei growth period with Photo-thermal effectiveness (PTE) as the scale parameter was established by using the data of different locations, years and varieties of test data, and the independent data Verify it. The results showed that the standard error of regression (RMSE) between the simulated and measured values for the number of days required for female inflorescences of Myrica rubra, such as female flower opening, leaf opening, fruit setting and fruit ripening, was 2.51, 1.83, 2.68, 2.70 and 2.45 d, respectively. And the developmental models based on the effective accumulated temperature (RMSE 8.02, 7.81, 5.46, 5.40 and 11.83 d) and PAR daily integral method (RMSE 8.28, 11.0, 8.52, 5.56 and 6.87 d) Compared with the simulation accuracy increased by 8.6% and 10.2%.
