一、光合作用与气肥农作物产量95%以上来自光合作用。即植物利用太阳光,将CO_2和水合成为有机物。空气中CO_2含量仅为330ppm,太低。因此,在温室或塑料大棚中增施co_2气(俗称施气肥)可以大幅度增加蔬菜产量(如可增产西红柿几倍)。这已成为发展高产优质农业的重要技术。二、气肥的施用方法1、用碳酸氢铵(化肥)加废硫酸混合,产生CO_2气体和硫酸按。一亩地大栩每次用约4公斤碳酸氢按混合2公斤废硫酸,搅拌均匀,在早晨和下午关闭大棚通风口后施放,从小苗6～7片叶连施30～60天。2、施“全福固气颗粒肥”(山东省农科院原子能所生产),均匀撤入土壤中,每亩用40公斤,撤一次可连续供气约40天。三、CO_2检测仪的研制
First, photosynthesis and gas fertilizer crops yield more than 95% from photosynthesis. That is, plants use sunlight to convert CO 2 and water into organic matter. Air CO 2 content of only 330ppm, too low. Therefore, adding greenhouse gas or plastic greenhouse co2 gas (commonly known as gas fertilizer) can greatly increase the yield of vegetables (such as tomatoes can increase the production several times). This has become an important technology for developing high-yield and high-quality agriculture. Second, the application of gas fertilizer 1, with ammonium bicarbonate (fertilizer) plus waste sulfuric acid mixed to produce CO 2 gas and sulfuric acid press. Large acres of acres of land each with about 4 kg of hydrogen carbonate by mixing 2 kg of waste sulfuric acid, stir, in the morning and afternoon after closing the greenhouse vents release from seedlings 6 to 7 leaves with 30 to 60 days. 2, Shi “Quan Fu solid gas fertilizer ” (Shandong Academy of Agricultural Sciences atomic energy production), uniform withdrawal into the soil, with 40 kg per mu, withdrawal can be a continuous supply of about 40 days. Third, CO_2 detector development
