摘要
实践证明，用磷铝质岩加工制成的新肥，不仅肥效显著，更有巨大的抗旱能力。据多年来的田间观测及初步研究成果可知，它的抗旱性能，主要由于共生的稀土中镧系所致。另在新肥生产中，要开展ＳＯ２的回收，并制得硫酸系列产品，提高厂家经济效益。化学肥料抗旱性能的发现，为其提供了极富前景的理论课题，并将产生明显的经济效益。
Abstract Practice shows that a new-type fertilizer which is made out of aluminiferous phosphate rocks is characteristic not only of considerable fertilizer effect but of higher anti-drought ability. Many years of cropland experiment,along with initial results in research,reveal that the anti-drought performance is due, to a great extant, to the coexistent lanthanide elements in the fertilizer. In addition, comprehensive utilization of the SO2 released in manufacturing the new- type fertilizer to produce H2SO4-seriated produce will in turn increase the economic profits ot the manufacturers.Discovery of anti-drought fertilizers will provide us with a new theoretical task of well Promising and thus possibly yeilding considerably economic profits.
