摘要
用硫酸与碳酸氢铵产生二氧化碳法，研究了不同浓度的二氧化碳对黄瓜产量的影响。结果表明，二氧化碳浓度为1000毫克／千克时，增产达30-34％，经济效益明显。
Effect of carbon dioxide at different concentration to cucumber yield was studied by sulphuric acid and ammonium bicaxhanate getting carboan dioxide.The result showed that carbon dioxide concentration of 1000 mg·L-1 and 1500 mg·L-1 could increased in cucumber yield of 30%～34% and had remarkable economic effect.
