近年来，涿州市棚（室）黄瓜产量一直在１００００～１１５００ｋｇ左右徘徊不前。为了寻求进一步提高棚（室）黄瓜产量的有效途径，除指导菜农加强栽培管理外，还引进了双微二氧化碳气肥进行了试验示范、并取得黄瓜全生育期增产８．５％，增值１４．８％的好成效。 试验试范地
In recent years, Danzhou shed (room) cucumber production has been wandering around 10000 ~ 11500kg. In order to find an effective way to further increase the yield of shed cucumbers, in addition to stepping up the cultivation and management of vegetable growers, we also introduced dual micro-carbon dioxide gas fertilizers to experiment and demonstration and achieved an increase of 8.5% and an added value of 14 during the whole growth period of cucumbers. 8% good results.
