摘要
主要针对番茄日光温室内作物光合作用相对较集中的上午CO_2浓度的变化规律进行探讨,目的在于找到比较合适的CO_2加浓时间以及加浓量,从而使日光温室内CO_2的加浓有一定的规律可循。为此,采用了数据回归的办法来拟合CO_2浓度整体的变化规律。
It is mainly discussed in this paper about the changing rule of CO2 concentration in the tomato solar greenhouse in the morning that the crop photosynthesis is relatively concentrated. The goal of the paper is to find a proper time and a proper amount for CO2 thickening, so that a rule could be followed in CO2 thickening in solar greenhouse. A regressive method is used to approach the whole changing rule of the CO2 concentration.
