1977年5月22日,广东省地质局七三五地质队,在三水盆地施工的水深九井发生井喷,每日喷出纯二氧化碳气500万立方米以上。第二年当地的水稻增产二成,用该井的气体对蔬菜施肥,使蔬莱增产40.9—398％,引起有关方面注意。佛山地区专门成立二氧化碳研究所,研究该井气体的综合利用问题。二氧化碳是一种肥效显著的“气肥”,国外一些先进国家已比较广泛地在温室或棚房中对作物施用二氧化碳。同时二氧化碳在工业、商业上的用途极广泛,特别是对粮食、种于、蔬菜和肉类的保鲜作用效果良好,其经济价值十倍于天然
On May 22, 1977, the Geological Team of the Guangdong Bureau of Geology, Seventy-five, produced a well blowout at the depth of 9 wells drilled in the Sanshui Basin and jetted more than 5 million cubic meters of pure carbon dioxide daily. The next year, the local rice yield increased by 20%, with the well of gas fertilizers on vegetables, vegetable yield increased 40.9-398%, causing the attention of the parties concerned. Foshan set up a carbon dioxide Institute, to study the comprehensive utilization of gas wells. Carbon dioxide is a fertilizers significant “gas fertilizer”, some foreign advanced countries have more widely in the greenhouse or greenhouse on the application of carbon dioxide. At the same time carbon dioxide in industrial and commercial use of a very wide range, especially for food, planting, vegetables and meat good effect of preservation, the economic value of ten times the natural
