二氧化碳是绿色植物进行光合作用,制造碳水化合物的重要原料。随着日光温室、大棚等设施栽培的发展,二氧化碳气肥将成为温室(棚)蔬菜生产上主要的增产措施之一。为此,我们于1994年进行该项目试验,1994年～1996年示范推广,取得了良好的经济效益和社会效益。现总结如下,以供农民朋友应用。 一、试验的基本情况与结果 1、试验的基本情况 此试验和示苑安排在皋兰县石洞乡和榆中县和平乡进行,所在温室均肥力上等管理水平良好。供试作物为黄瓜。所用材料为碳铵(榆中氮肥厂)和硫酸(工业用
Carbon dioxide is an important raw material for photosynthesis of green plants and carbohydrates. With the development of solar greenhouse, greenhouse and other facilities cultivation, carbon dioxide gas fertilizer will become one of the major stimulation measures for greenhouse vegetable production. To this end, we conducted the project test in 1994, from 1994 to 1996 demonstration and promotion, and achieved good economic and social benefits. Are summarized below, for farmers and friends to use. First, the basic conditions and results of the test 1, the basic situation of the test This test and show Court arranged in Gaolan County Shidong Township and Yuzhong County Heping Township, where fertile greenhouse fertility level management level is good. The test crop is cucumber. Materials used for ammonium bicarbonate (Yuzhong nitrogen fertilizer plant) and sulfuric acid (industrial use
