摘要
为研究辣椒果实生长发育与环境因子之间的关系以及建立辣椒产量预测模型,为辣椒果实的无损测定提供理论和技术支撑,对不同辣椒品种的试验数据进行处理,构建基于生理发育时间的果实纵、横径生长模型,以及果实鲜重与纵、横径关系的线性模型,并建立了以上述模型为基础的辣椒产量预测模型。运用独立试验数据对模型进行检验,结果显示:除Y187果实纵径和横径的均方根误差(RMSE)>20%外,其余模型RMSE均小于20%,表明,所建模型具有较高的预测精度,能够很好地模拟辣椒果实生长和产量形成。
To find out the relationship between fruit growth of chilipeper and environment factors, to previde a theoretical basis and technical support for the production of chilli, and to construct a prediction model of chilli yield, according to the data analysis of various chilli varieties, some models were established, such as the growth models of the fruit transverse and vertical diameters with physiological development time, linear models of fresh fruit weight with the transverse diameter and vertical diameter. The chilli yield prediction model was established as well based on the above models. Independent data were employed to verify these models. The result indicated that these models with high precision could be used to predict the fruit growth and yield.
