Plant biomass and fruit yield in spring were larger than in autumn, due to higher growing degree days. 春季植株的总生物量和经济产量大于秋季,这是由春季生长期间高的积温所决定的。
The results show that the model can predict leaf area and total dry weight of greenhouse muskmelon more accurately than the traditional specific leaf area ( SLA ) and growing degree days ( GDD ) based models. 结果表明,本模型较用比叶面积和叶干重的SLA法及用积温与叶面积的函数的GDD法更能准确地模拟温室甜瓜的LAI和植株总干重。
