根据光温对菊花品质的影响,通过不同定植期和不同品种试验,建立了以生理辐热积(physiological product of thermaleffectiveness and PAR,PTEP)为尺度的温室标准切花菊品质预测模型,并用独立的试验数据对模型进行检验.结果表明:模型对温室标准切花菊的展叶数、单株叶面积、株高、茎粗、节间长和花径的模拟值与实测值的符合度较好,模拟值与实测值基于1∶1线的决定系数(R2)和预测相对误差(RSE)分别为0.99、0.98、0.98、0.92、0.87、0.88和5.5%、6.5%、5.9%、4.1%、11.2%、12.4%.表明该品质预测模型预测精度高、实用性强,可为温室标准切花菊生产中的光温调控提供理论依据和决策支持.
According to the influence of light temperature on the quality of chrysanthemums, the quality prediction model of greenhouse chrysanthemum with physiological product of thermaleffectiveness and PAR (PTEP) was established through different colonization periods and different varieties tests. Data were used to test the model.The results showed that the simulated values of leaf number, plant leaf area, plant height, stem diameter, internode length and flower diameter of the standard cut chrysanthemum in greenhouse were in good agreement with the measured values, and the simulation The determination coefficient (R2) and the prediction relative error (RSE) based on the 1: 1 line between the value and the measured value are 0.99, 0.98, 0.98, 0.92, 0.87, 0.88 and 5.5%, 6.5%, 5.9%, 4.1%, 11.2% , 12.4% respectively, indicating that the quality prediction model has high prediction accuracy and good practicability, which can provide theoretical basis and decision-making support for light and temperature regulation in greenhouse standard cut chrysanthemum production.
