1.生物固氮研究将导致肥料施用技术的变革 利用固氮微生物与藻类,将是建立作物营养综合体系(IPNS)的一大领域。由于生物固氮研究有着重要意义。20多年来一直是美、英、法、德、澳、日等国家的重点科研项目。目前,我国山东大学用植物生长激素处理由愈伤组织分化出来的小麦幼苗根部,培养出世界上第一个人工小麦根瘤,在接种适当的固氮微生物后,根
1. Biological nitrogen fixation research will lead to changes in fertilizer application technology The use of nitrogen-fixing microorganisms and algae will be a major area for the establishment of an Integrated Crop Nutrition System (IPNS). Because of biological nitrogen fixation research is of great significance. For more than 20 years, it has been a key scientific research project of the United States, Britain, France, Germany, Australia, Japan and other countries. At present, our country Shandong University of plant growth hormone treated callus differentiated from the roots of wheat seedlings, cultivate the world’s first artificial wheat nodules, after inoculation of appropriate nitrogen-fixing microorganisms, roots
