摘要
对 CROPGRO 作物生长模型进行了调整，以分析在佛罗里达州肯尼迪航天中心进行的二氧化碳水平升高（1200 微摩尔-1）条件下的大豆（Hoyt 栽培品种）实验数据。对原始 CROPGRO 进行以下调整后，模型与气体交换数据一致：输入方波温度和光合有效辐射（PAR）曲线；输入适当的水培基质 PAR 反照率；修改生物量分配和发育参数；增加第五个植株节的叶面积扩展率；减少第五个植株节后的比叶面积；增加入射漫射 PAR 分数，使其高于典型的实地值。这里展示的模型表明，随着不断发展，修改后的 CROPGRO 将成为分析和最终优化生物再生生命支持系统中豆科植物生产的有用工具。
A modified CROPGRO model for simulating soybean growth in controlled environments.
The CROPGRO crop growth model is adapted in order to analyze experimental data from a soybean (cv. Hoyt) experiment conducted at elevated CO2 levels (1200 micromol mol-1) at Kennedy Space Center, FL. The following adaptations to original CROPGRO produced model agreement with gas-exchange data: the input of square-wave temperature and photosynthetically active radiation (PAR) profiles; the input of the appropriate hydroponic substrate PAR albedo; modified biomass partitioning and developmental parameters; an increased leaf area expansion rate through the fifth vegetative node; a decreased specific leaf area after the fifth vegetative node; and an increased incident diffuse PAR fraction over typical field values. The model demonstrated here suggests that with continued development, modified CROPGRO will be a useful tool in the analysis and eventual optimization of legume production in bioregenerative life support systems.
