英文摘要 | 为提高设施农业增施CO_2的利用效率和经济效益,减少CO_2的逸散损失,降低成本,本研究以增施CO_2利用效率计算方法为基础,分析了增施CO_2利用效率的可能影响因素,探讨了提高CO_2施肥经济效益的有效技术与方法。分析表明,影响增施CO_2利用效率的主要因素为设施的换气次数、设施内外CO_2浓度差和植物的光合能力。因此,在进行CO_2施肥时,应综合考虑植物种类、生育阶段、栽培条件及其他环境要素等条件,选择适宜的CO_2增施方法、施肥浓度和施肥时间。; To improve the utilization efficiency and economic benefits of enriched CO_2 and reduce the CO_2 leaked outside and the operation cost of protected agriculture, the possible effect factors on the enriched CO_2 utilization efficiency are analyzed based on calculations in this paper,. The effective methods and technologies to improve the enriched CO_2 utilization efficiency are discussed. The result shows that the main effect factors on the enriched CO_2 utilization efficiency are the air exchange rate, CO_2 concentration difference between inside and outside facilities and the plant photosynthetic capacity. To maximize the enriched CO_2 utilization efficiency, the optimum CO_2 enriched method, CO_2 enriched concentration and enriched time should be decided by considering plant species, growth stage, cultivation conditions, other environmental factors, etc., when the CO_2 enrichment is conducted. |
