CO_2气肥技术在设施蔬菜上的应用

Application of CO_2 Gas Fertilizer on Vegetables in Facilities

CO_2是蔬菜进行光合作用的主要原料之一,直接影响蔬菜的生长发育。设施大棚CO_-2不足导致蔬菜不能进行正常的光合作用,影响蔬菜的产量和质量,同时也会影响设施蔬菜的经济效益,因此合理施用CO_-2气肥是设施蔬菜增收节支的一项有效措施。文章介绍了CO_-2气肥施用技术在设施蔬菜上的作用、施用方法、施用浓度、注意事项、施用时间等。

CO2 is one of the important raw materials for vegetable photosynthesis,which directly affects the growth and development of vegetable.Insufficient CO2 in greenhouse can easily cause vegetable not to carry out normal photosynthesis,affect the yield and quality of vegetables,but also affect the economic benefits of greenhouse vegetables.Therefore,rational application of CO2 gas fertilizer is an effective measure to increase the income and save expenses of greenhouse vegetables.This paper introduced the function,application method,application concentration and application time of CO2 gas fertilizer in greenhouse vegetable application.
