摘要
为准确模拟烟草叶片发生进程、为烟叶生产精准管控提供参考依据,2022-2023年连续2年设置不同移栽期田间对比试验,建立基于不同尺度的烟草叶片数目变化动态模型,分析不同模型的模拟精度。结果表明,叶片发生速率随移栽期推迟而加快,达到最大叶片数的时间缩短,不同移栽期最终叶片数目基本一致;烟草叶片发生模型为无稳定增长期的非典型“S”型生长曲线;生长度日模型精度高于生长天数模型,在温度变化处于适宜范围时具有一定的实用性,温光效应模型精度高于生长度日模型,但预测精度在年度间存在波动,生理发育时间模型精度高于其他模型;山东烟区在4月下旬至5月下旬的移栽时间范围内,烟草叶片数目达到最大值的时间为37.63~46.62,生长度日为440.06~483.04,温光效应值为30.17~34.36,生理发育时间为29.13~31.80。基于生理发育时间的烟草叶片发生模型具有更高的可靠性与普适性,可准确表征植株发育进程,为烟叶生产精准管理提供支撑。
In order to accurately simulate the initiation process of tobacco leaves and provided reference for precise management and control of tobacco production,field comparison experiments of different transplanting date treatments were carried out for two consecutive years from 2022 to 2023 to establish dynamic models of tobacco leaf changes based on different scales,and the simulation accuracy of different models was analyzed.The results showed that the rate of leaf initiation accelerated with the delay of the transplanting date,and the time to reach the maximum number of leaves was shortened.The final number of leaves(A value)in different transplanting dates was basically the same.The leaf initiation models of tobacco was an atypical“S”type growth curve with no stable growth period.The accuracy of the growing degree days model was higher than that of the growing day model,which had better practicality when the temperature changed in the appropriate range.The accuracy of the thermal-photo effectiveness model was higher than the growing degree days model,however,the prediction accuracy fluctuated across different years.The accuracy of the physiological development time model was higher than other models.The time for the tobacco leaves number to reach the maximum value was 37.63-46.62,the growing degree days was 440.06-483.04,the thermal-photo effectiveness value was 30.17-34.36,and the physiological development time was 29.13-31.80,in the transplanting date from late April to late May in Shandong tobacco area.The simulation model of tobacco leaf initiation based on physiological development time had higher reliability and universality,which could accurately characterize the process of plant development and provide support for the precise management of tobacco production.
