基于生物量的冬小麦越冬前植株地上部形态结构模型
Aboveground Architecture Model Based on Biomass of Winter Wheat before Overwintering
摘要
Abstract
The aboveground morphogenesis is an important basis of plant morphological construction and visualization for winter wheat before overwintering. For quantitatively analyzing the relationship between the aboveground architectural parameters and organ biomass of winter wheat before overwintering, field experiments with different varieties (Jimai 22, Tainong 18, and Luyuan 502) and nitrogen levels were carried out in 2013-2014 and 2014-2015 wheat growth seasons. Simulation models for above-ground architectural of winter wheat before overwintering were built with the 2013-2014 dataset of aboveground architectural parameters before overwintering and organ biomass and validated by the 2014-2015 dataset, showing the models exhibited satis-factory predictions for leaf blade length, leaf maximum blade width, leaf blade tangent angle, and leaf blade bowstring angle, except for leaf sheath length and leaf bowstring length. The models built in this study are suitable to simulate the aboveground architecture of winter wheat varieties before overwintering under different nitrogen levels.关键词
