     水溶性聚磷酸銨憑借以下優(yōu)點(diǎn)進(jìn)入液體肥料生產(chǎn)領(lǐng)域,并已在歐美等發(fā)達國家廣泛應用:


     1、是含有農作物生長(cháng)所需的氮、磷元素的高濃度肥料;

     2、肥料呈中性,對土壤和作物有較高的安全性和改善性;

     3、對金屬離子有較好的螯合作用,可以添加一些微量元素提高肥效;

    4、肥料施入土壤中,聚磷酸銨中的正磷酸根會(huì )先被植物吸收利用,土壤的理化性質(zhì)會(huì )使聚磷酸根逐漸分解,慢慢變?yōu)檎姿岣峁┲参锢?,因而肥料具有緩效作用?/span>

Water-soluble ammonium polyphosphates enter the field of liquid fertilizer production by virtue of the following advantages, and has been widely used in Europe and America and other developed countries:


1. It is a high concentration fertilizer containing nitrogen and phosphorus required for crop growth;

2. The fertilizer is neutral and has high safety and improvement to soil and crops; 

3. It has good chelation to metal ions, and can add some trace elements to improve fertilizer efficiency; 

4. When fertilizer is applied to the soil, the orthophosphate root in ammonium polyphosphate will be absorbed and used by plants first. The physical and chemical properties of the soil will cause the polyphosphate root to gradually decompose and gradually become orthophosphate root for plant use, so the fertilizer has a slow effect.
