1) the polymer slow-release fertilizer
高分子缓释化肥
1.
Firstly, phosphoryl thiourea potassium was synthesized with the urea and potassium dihydrogen phosphate; Then the urea-formaldehyde oligomers was also synthesized by condensation polymerization between the formaldehyde and urea; eventually, the polymer slow-release fertilizer was obtained by the condensation reaction between urea-formaldehyde oligomers and phosphoryl thiourea potassium.
本研究以小分子化肥尿素和磷酸二氢钾为起始原料,通过缩聚反应,研发出一种以氮、磷、钾、碳、氢、氧六种元素为主链结构的高分子缓释化肥,同时解决了化肥工业中“多营养元素化”和“缓控释化”两个难题。
