摘要
针对我国温棚面积大，温棚内ＣＯ２浓度过低，严重影响植物光合作用的现状，本项目进行了有关ＣＯ２气体肥料对温棚蔬菜效果的研究。经对多品种蔬菜试验和推广试验表明，ＣＯ２气肥可使温棚蔬菜增产２０～６０％，并可提高蔬菜品质、提高抗病能力及提早上市。
According to the large area of greenhouse in our country and low CO 2 density, it affects serious plant photosynthesis, so we have studied to CO 2 gas fertilizer. At the condition of some sorts of vegetable test and enlarge experiment, it can increases pruduction about 20～60%、improvesquality、resists plant disease and markets forwardness. The item makes use of planting for greenhouses and sheds easily.
