磷是农作物生长的三要素之一,是营养庄稼的粮食,随着我国农业的不断发展,农业生产上对磷肥的需要越来越迫切,所以磷肥的生产对当前农业的发展是急不可待的。文化大革命后,小磷肥厂遍地开花,很多社队和学校的校办工厂都就地取材,土法生产磷肥,有力地支援了农业生产。为了更好的支援农业生产,使各地土法生产磷肥的工作更普遍开展,在此把磷肥生产的硫酸用量的理论计算,以及控制硫酸用量——游离酸含量的测定的意义和方法作以介绍,可供各地土法生产磷肥参考。
Phosphorus is one of the three elements of crop growth and is the food of nutritious crops. With the continuous development of agriculture in our country, the demand for phosphate fertilizer in agricultural production is becoming more and more urgent. Therefore, the production of phosphate fertilizer is in dire need of the current agricultural development . After the Cultural Revolution, a small number of phosphate fertilizer plants flowered everywhere. Many communes and school-run school-owned factories sourced local materials, and indigenous production of phosphate fertilizer strongly supported agricultural production. In order to better support agricultural production, so that the local production of phosphate fertilizer by indigenous work more generally, here the theoretical calculation of the amount of sulfuric acid used in phosphate fertilizer production, as well as the control of the amount of sulfuric acid - the meaning and methods of determination of free acid , For all around the production of phosphate fertilizer reference.
