摘要: 黄瓜是中国温室栽培的最主要作物之一,果实负载决定着果实发育和产量,构建不同果实负载下温室黄瓜干物质分配模型对温室黄瓜栽培管理具有重要的理论意义和实践价值。根据温室黄瓜生长对光温需求,以辐热积(TEP)为尺度建立温室黄瓜干物质分配模型,并用与建模试验不同的试验数据进行模型检验。模型对温室黄瓜茎、叶和果实干质量的预测结果与实测值1∶1线回归估计标准误(RMSE)和决定系数(R2)分别为223.08、119.23、316.34 kg/hm2和0.76、0.73、0.75,模型的预测结果与实测值之间的吻合度较好。Abstract: Cucumber is one of a major greenhouse crop and an important horticultural crop in China. Cucumber production and fruit development are correlated with fruit load. Found the simulation model of greenhouse cucumber under different fruit load conditions can
