我所在1973年利用本省中、低品位磷矿研制成磷酸铵悬浮液体肥料(简称磷铵).它是一种含氮磷的复合肥料,含N6～8%,含P_2O_520～24%,pH近中性,具有速效、高效、长效兼备的优点.从1973至1976年先后在全省6个地区、17个县、74个点上进行不同土壤、不同作物肥效试验,普遍获得不同程度的增产效果.在各类新化肥品种试验中,磷铵最受群众欢迎,肖山县贫下中农把这种“磷氮肥”称为“灵丹肥”.现将几年来试验结果综述于后.
I am in 1973 using the province’s low-grade phosphate rock developed into ammonium phosphate suspended liquid fertilizer (referred to as ammonium phosphate). It is a nitrogen-phosphorus containing compound fertilizer, containing N6 ~ 8%, containing P2O5 520 ~ 24%, pH near Neutral, with quick, efficient, long-term both advantages.From 1973 to 1976 successively in the province six areas, 17 counties, 74 points on different soil and fertilizer testing of different crops, generally gain different levels of yield Effect in all kinds of new varieties of fertilizer trials, the most popular ammonium phosphate crowd, poor peasants in Xiaoshan County, this “phosphorus and nitrogen fertilizer,” known as “Ling Dan fat.” Now the results of several years reviewed in the post.
