由上海化工研究提供的硝酸磷肥,主要成份为硝酸铵、磷酸一铵和磷酸二钙,是兼含氮磷两种元素的颗粒状复合化肥。小麦用的硝酸磷肥含 N20.78%,P_2O_5 20.74%,棉花用的含 N22.27%、P_2O_5 18.07%。用作基肥和早期追肥,有早发健苗、稳长增产的作用。1977—1979年试验,每公斤硝酸磷肥增产小麦2.54公斤,较施等 N 量磷酸铵、硝酸铵和硫酸铵.每公斤 N 分别多增0.13公斤、
Nitric acid phosphate fertilizer, which is provided by Shanghai Chemical Industry Research Institute, is mainly composed of ammonium nitrate, monoammonium phosphate and dicalcium phosphate. It is a granular compound fertilizer containing both nitrogen and phosphorus. Nitrogen phosphate used in wheat contains 20.78% of N, 20.74% of P 2 O 5, 22.27% of cotton and 18.07% of P 2 O 5. As a base fertilizer and early dressing, there are early health Jianmiao, the role of steady production. From 1977 to 1979, 2.54 kilograms of wheat per kilogram of nitrophosphate was produced, which was 0.13 kilograms more than N ammonium phosphates, ammonium nitrate and ammonium sulfate respectively,
