中国唯一国家缓控释肥工程技术研究中心日前落户山东金正大集团。“杂交水稻之父”、中国工程院院士袁隆平为中心题词。据了解,为确保粮食增产,中国大量使用化肥,消费了世界35%的化肥。但到上世纪90年代初,在化肥用量直线增长的同时,粮食产量却增长缓慢。造成这一尴尬局面的原因是传统化肥利用率低。
China’s only state controlled release fertilizer engineering technology research center recently settled in Shandong Jinzheng Group. “Father of hybrid rice ”, Yuan Longping, academician of Chinese Academy of Engineering as the center inscription. It is understood that in order to ensure grain production, China makes extensive use of fertilizers and consumes 35% of the world’s fertilizers. However, by the early 1990s, while the amount of fertilizer used had risen linearly, the output of grain increased slowly. The reason for this embarrassing situation is the low utilization rate of traditional fertilizers.
