生物高效复合肥是由北京大学技术物理系、生物系联合固氮科研组经多年研制成功的一种新型世界领先肥料,1991年被专家们评为国内先进水平,同年荣获北京第二届国际博览会生物肥唯一的金奖。昌黎县从1990年开始连续三年进行试验。昌黎镇农技站近二年来曾对小麦、蔬菜、果树作了多点试验,增产效果明显,其中小麦拌种试验14户,平均增产15.5％。推广示范面积200多亩,每亩只花1.5元就可多收小麦30—50公斤。该肥施用方法简单,易被群众掌握。
Bio-Efficient Compound Fertilizer is a new type of world-leading fertilizer successfully developed by the Department of Technical Physics of Peking University and the Department of Biology of Combined Nitrogen Research and Development. In 1991, it was appraised as the advanced domestic level by experts. In the same year, Bio-Efficient Compound Fertilizer won the prize of the second Beijing International Exposition Biological Fat only gold medal. Changli County for three consecutive years since 1990 experiments. In the past two years, Changli Agricultural Technology Station made many experiments on wheat, vegetables and fruit trees, with obvious stimulation effect. Among them, 14 were wheat seed dressing trials, with an average yield of 15.5%. Demonstration area of 200 mu to promote, only 1.5 yuan per acre can receive more wheat 30-50 kg. The fertilizer is simple, easy to grasp by the masses.
