一种专门用于棚(室)菜保护地设施追施二氧化碳气肥的发生器,目前已批量投入生产。众所周知,由于棚(室)等保护地设施是处于相对密闭的栽培场地,往往由于蔬菜等栽培作物进行光合作用时,造成棚(室)内二氧化碳不足,而限制了蔬菜等作物的增产增收。为弥补棚(室)生产蔬菜过程中存在的这一缺欠,有利实现增产增收,近年来,国内各大中城市都在研究、试验,示范有关施用二氧化碳的有效方法。目前,经河北省农业厅土壤肥料测试中 A dedicated greenhouse (greenhouse) facilities for top-dressing carbon dioxide gas fertilizer generator, has been put into mass production. It is well-known that greenhouse facilities such as shelters are located in relatively confined cultivation areas and often result in insufficient production of vegetables and other crops due to the lack of carbon dioxide in the greenhouse due to the photosynthesis of cultivated crops such as vegetables. In order to make up for the shortcomings in the production of vegetables in the greenhouse (greenhouse), it is beneficial to increase production and income. In recent years, large and medium-sized cities in China have been studying, testing and demonstrating effective methods for applying carbon dioxide. At present, by the Hebei Provincial Department of Agriculture soil and fertilizer testing
