为研究不同密度下温室番茄的生长行为,对结构功能模型GreenLab进行改进,在提高拟合度的基础上,获得不同密度下番茄生长参数,通过参数分析将环境与番茄植株生长行为相联系。结果表明密度影响同化物产生与分配,通过外在形态,如出叶速率、叶厚、坐果率等表现,GreenLab模型可以重建这种生长行为变化。
A study was conducted at Wheat Research Institute, AARI, Faisalabad, Pakistan during 2004-05 and 2005-06 to understand dynamics of aphid infestation as affected by weather and wheat sowing time. Dai...
