今年七月二十五日至八月七日,在北京召开了全国化肥使用座谈会。会议对当前化肥使用技术上存在的若干问题进行了分析研究。认为在肥料的使用过程中,由于施肥方法不当而造成的化肥损耗是很严重的。据典型调查,目前化肥使用后,作物只能吸收30％,其余70％都损耗了。如果我们能把现有化肥的利用率提高10％,就等于为国家增加几百万吨化肥,能多增产一至二百亿斤粮食。 July 25 this year to August 7, held in Beijing, the national fertilizer use forum. The conference analyzed and analyzed some technical problems existing in the current fertilizer use. That the use of fertilizer in the process, due to improper methods of fertilizers caused by the loss of fertilizer is very serious. According to a typical survey, the current use of fertilizers, the crop can only absorb 30%, the remaining 70% are depleted. If we can increase the utilization rate of existing fertilizers by 10%, it will mean adding millions of tons of fertilizers to our country and increasing the output of 1-2 billion kilos of grain.
