生物固氮对于人类生产和生活有着十分重大的意义,而生物固氮资源的开发和利用则是农业生产上的重要课题之一。近几年我国生物固氮应用研究及生产推广出现了良好的局面,发展很快。1982年12月在北京召开的全国生物固氮应用研究学术讨论会充分反映了这个方面的进展,概括起来有几个方面: 1、生产应用面积和范围不断扩大。不但有许多万亩的示范片,而且也有象辽宁省几年推广应用达到200万亩以上的典型;不但有花生、大豆等根瘤菌,而且配合国家
Biological nitrogen fixation is of great significance to human production and life, and the development and utilization of biological nitrogen fixation resources are one of the important issues in agricultural production. In recent years, China’s application of biological nitrogen fixation and production and promotion of a good situation, the rapid development. The National Symposium on Biological Nitrogen Fixation Applied Research held in December 1982 in Beijing fully reflected the progress in this aspect. To sum up, there are several aspects: 1. The area and scope of production and application are constantly expanding. Not only have many mu of demonstration films, but also have been popularized and applied in Liaoning province for several years to reach more than 2 million mu of typical; not only peanuts, soybeans and other rhizobia, but also with the country
