肥料級磷酸氫鈣俗稱白磷肥或者白肥,是生產(chǎn)飼料級磷酸氫鈣的副產(chǎn)品,主要用作配置復(fù)混肥的原料,也可直接施用于農(nóng)田。白肥施入土壤后,滿足作物前期生長需要,為作物的中后期生長提供養(yǎng)分;與重鈣和過磷酸鈣相比,水分含量低,易于復(fù)混肥生產(chǎn)控制;顆粒細,提高復(fù)混肥外觀質(zhì)量。肥料級磷酸氫鈣溶于土壤中,釋放多種微量元素,可作為各種微量元素的補充。
Fertilizer-grade calcium hydrogen phosphate, commonly known as white phosphate fertilizer or white fertilizer, is a by-product of the production of feed-grade calcium hydrogen phosphate. It is mainly used as raw material for compounding fertilizer, and can also be directly applied to farmland. When white fertilizer is applied to soil, it can meet the needs of early crop growth and provide nutrients for the middle and late crop growth. Compared with heavy calcium and superphosphate, it has low water content and is easy to control the production of compound fertilizer. It has fine particles and improves the appearance quality of compound fertilizer. Fertilizer-grade calcium hydrogen phosphate dissolves in the soil and releases many trace elements, which can be used as a supplement to various trace elements.
