摘要
在可控环境下通过改变温度、光照强度和相对湿度的不同水平梯度组合,研究这3个因子对黄瓜叶片净光合速率的综合影响;通过最小二乘法进行多元非线性参数回归,建立黄瓜叶片净光合速率对这3个因子的响应模型。研究了模型规律,并依据生长环境最优和经济性最优原则,提出了可控温室环境优化的调控策略。
To explore the quantitative relationship between photosynthesis of greenhouse Cucumber and the microclimate,including temperature,relative humidity and light intensity,the photosynthetic characteristics in controllable condition was studied.The photosynthetic production function of cucumber was established preliminarily,with which meteorological resources can be utilized and controlled reasonably by optimizing the environmental factors.
