基于生物量的辣椒果实几何参数模拟分析

Simulation Analysis on Geometrical Parameters of Pepper Fruit Based on Biomass

为了对辣椒生产提供理论依据和决策支持,以黔椒4号、Y-187、火焰山和绿炬为材料,设置品种与氮素田间试验,分析了不同品种辣椒果实纵径和横径之间以及果实干重与体积之间的定量关系,引入校正系数K和M构建基于生物量的辣椒果实几何参数模型。结果表明,不同品种类型辣椒果实纵径和横径的关系可用幂指数方程表达,果实干重随体积呈线性变化。运用独立试验调查数据对模型进行初步检验,模型对辣椒果实纵径和横径动态变化规律具有较好的预测性,所建模型能较好地模拟不同生长条件下辣椒果实的主要几何参数,为构建辣椒功能—结构模型奠定了基础。

To provide support for theoretical basis and policy decision of pepper production,taking Qianjiao 4,Y-187,Huoyanshan and Lvju as the materials,a field test was conducted to analyze the relationship between vertical and transverse diameters as well as dry weight of the fruit and its volume.Then coupled with introduced correction coefficient K and M,a dynamic model of geometrical parameters of pepper fruit was developed.The results indicated that the relationship between vertical diameters and transverse diameters of pepper fruit could be expressed by power function.Meanwhile,dry weight of the fruit changed with its size in line equation.The model had a good predictability on pepper fruit vertical and diameter variation by using independent experimental data.The model could simulate the geometrical characteristics of pepper fruit under different growth conditions.The study laid the foundation for developing a pepper function and structure model.
