含氮磷高分子肥料的制备和结构研究

Synthesis and structure study of polymer fertilizers containing nitrogen and phosphorus

水溶性合成高分子聚合物能被微生物分解,是一种优良的土壤改良剂,并对土壤营养元素有良好的吸附作用,可减少元素流失,提高肥效。合成了一种营养元素高分子缓释化肥,将含氮磷的降解水溶性高分子材料引入到化肥领域,并通过实验研究不同的反应工艺条件对高分子肥料结构和含氮磷肥效的影响。

Water-soluble polymer is a good soil conditioner which can be decomposed by micro-organisms. It has a good ad- sorption to soil nutrients so that the loss of element is reduced and the fertilizer efficiency is improved. A kind of slow release polymer fertilizer with nutrient elements is synthesized by adding degradable water-soluble polymer materials containing nitro- gen and phosphorus. The effects of reaction conditions on the fertilizer structure and efficiency are studied in laboratory.
