| 摘 要： | 采用车箱理论方法，根据棉花生长发育过程中光合产物的源、库、流关系和供需平衡，定量模拟了不同品种、播期棉花蕾铃发育和脱落动态。结果显示，棉花单株蕾数、成铃数、吐絮铃数的模拟值与观察值之间的RMSE分别平均为3.36、1.57和1.04（个）；单铃重的RMSE为0.15 g；脱落率的RMSE为8.15%。表明应用本系统模拟蕾铃发育和脱落

| Abstract: | This simulation model applied escalator boxcar train method to simulate cotton boll development and abscission for different cultivars and sowing dates based on the relationship of assimilation source, flow, sink and the balance of supply and demand during cotton growth and development.The results showed that the average RMSE between simulated and observed values for numbers of square, big boll and open boll per plant were 3.36, 1.57 and 1.04, respectively.The RMSE for single boll weight and abscission ratio were 0.15 g and 8.15%.Thus, this methodology for simulating boll development and abscission process is precise and reliable. |
