有些专家认为,稀土微肥每年可增产粮食及豆类产量近10亿公斤。 1993年以来,稀土又作为碳铵的改性剂而取得了重大突破。稀土碳铵复合肥有效地解决了碳铵有效养份含量和易挥发等问题,其肥效与尿素相当。随着稀土农用产品品种的多样化、多元化,稀土碳铵复合肥的开发生产已成为当前稀土农用的一大热点。改造一座年产3.5万吨的小碳铵厂为等量的尿素厂,需投资7000—8000万元,
Some experts believe that rare earth micro-fertilizer can increase grain and bean production by nearly 1 billion kilograms per year. Since 1993, rare earths have made major breakthroughs as a modifier for ammonium bicarbonate. The rare earth ammonium bicarbonate compound fertilizer effectively solves the problems of effective ammonium nutrient content, volatilization, and the like, and its fertilizer effect is equivalent to that of urea. With the diversification and diversification of rare earth agricultural product varieties, the development and production of rare earth ammonium bicarbonate compound fertilizer has become a major hot spot for current rare earth agricultural use. The transformation of a small-carbon ammonium plant with an annual output of 35,000 tons is equivalent to a urea plant, which requires an investment of 7,000-80 million yuan.
