1992年北京市土肥站与海淀区土壤分析仪器厂合作试制14台二氧化碳发生器,分别在郊区县试用,效果良好。1993年已有8个县(区)近200台。最近,土肥站到郊区昌平县南邵乡考察使用情况表明,这种发生器使用简便、省时、省力、安全可靠,很受欢迎。1992年北京市推广二氧化碳施肥300亩,增产蔬菜448.5公斤,增加收入132.28万元。二氧化碳发生器的研制成功,将使郊区保护地蔬菜的施肥技术更加科学化。
In 1992, Tucheng Fertilizer Station of Beijing and Haidian District Soil Analytical Instrument Factory collaborated to produce 14 sets of carbon dioxide generators, which were tested in suburban counties with good results. In 1993, there were nearly 200 counties (districts) in eight counties. Recently, the application of soil fertilizer stations to the south Shao Township in Changping County of the suburbs indicated that this generator is very easy to use, time-saving, labor-saving, safe and reliable, and very popular. In 1992, Beijing promoted 300 mu of carbon dioxide fertilization and added 448.5 kilograms of vegetables to increase revenue of 1,322,800 yuan. The successful development of the carbon dioxide generator will make the fertilization technology of vegetable in suburban protected areas more scientific.
