据测定 ,一般作物生长所需二氧化碳的适宜浓度为１０００～１５００ｍｇ／ （毫克／公斤） ,而棚（室）内二氧化碳的浓度却远远低于这个标准 ,一般仅为１００ｍｇ／ 左右。所以棚（室）蔬菜在生产过程中必须施用二氧化碳气肥 ,才能获得增产增收。那么在使用二氧化碳发生器过
It is determined that the appropriate concentration of carbon dioxide required for crop growth generally ranges from 1000 to 1500 mg / kg, while the concentration of carbon dioxide in the greenhouse is far below this level, typically only about 100 mg / kg. So shed (room) vegetables in the production process must use carbon dioxide gas fertilizer, in order to obtain increase production and income. Then use carbon dioxide generator too
