在我国人口众多可耕地有限的情况下,必须大力抓好农业科学技术的推广应用工作,以推动农业的可持续发展。其中一个突出问题,就是要抓好优质肥料以提高单产。姜春云副总理作了批示:“应当十分重视生物肥料的开发应用。拟专门开一次有机肥经验交流现场会,专题讨论,作出部署”。为了更好地领会和贯彻春云同志的指示精神,现就生物肥料的推广应用问题谈一点看法。“庄稼一枝花,全靠肥当家”。传统农业依靠农家肥,而现代农业更多地依赖化肥。一个世纪以来,随着化肥工业的兴起和发展、农田化肥施用量的增加,农作物的产量有了很大增长。毫无疑问,化肥为人类作出了巨大的贡献。但是,化肥有很多副作用.在目前的施肥技术和水平下,施入农田的化学肥料的作物利用率通常仅为30%-50%。其中旱地损失量在 Under the circumstance that our country has a large population and limited arable land, we must vigorously promote the popularization and application of agricultural science and technology in order to promote the sustainable development of agriculture. One of the salient issues is to focus on good quality fertilizers to increase yields. Vice Premier Jiang Chunyun made a commendation: “We should attach great importance to the development and application of biological fertilizers. We are going to open a special meeting on site exchange and discussion on organic fertilizer experiences and make arrangements for the deployment.” In order to better understand and implement Comrade Chun Yun’s instructions, we now talk about popularization and application of biological fertilizers. “A crop of flowers, all by the fat home”. Traditional farming relies on farmyard manure, while modern agriculture relies more on fertilizers. Over the past century, with the rise and development of the fertilizer industry and the increase of the amount of chemical fertilizers applied to farmland, the output of crops has greatly increased. There is no doubt that fertilizer has made a huge contribution to mankind. However, there are many side effects of chemical fertilizers, which are usually only 30% -50% of crop utilization under current fertilizer technologies and levels. The amount of dry land loss in the
