腐植酸复肥(简称腐肥)是由辽宁省化工研究所与瓦房店化工厂研制成的配成复合肥。它是以草炭、尿素、过磷酸钙、硫酸钾等为原料按一定养分比例经工艺加工配制而成的。含N8～10%、磷(P_2O_5)8～10%、钾(K_2O)3～6%、腐植酸(HA)4～6%,是一种有机与无机相结合的颗粒肥料,因有养分含量高(20%以上),物理性状好(颗粒状),便于贮运与施用等优点,受到生产者普遍欢迎。特别是其在果树上可以实现年生长周期1次投肥,既省工、省力又效果明显、格外受到果农的青睐。
Humic acid compound fertilizer (referred to as rotten fertilizer) by the Liaoning Provincial Institute of Chemical and Wafangdian Chemical Plant developed into compound fertilizer. It is based on peat, urea, superphosphate, potassium sulfate as raw materials by a certain proportion of nutrients formulated by the process. Containing N8 ~ 10%, phosphorus (P_2O_5) 8 ~ 10%, potassium (K_2O) 3 ~ 6%, humic acid (HA) 4 ~ 6%, is a combination of organic and inorganic particulate fertilizer, due to nutrient content High (more than 20%), good physical properties (granular), easy storage and application, etc., are generally welcomed by producers. In particular, its fruit trees can achieve annual growth cycle 1 fertilization, both labor-saving, labor-saving and effective, exceptionally favored by the farmers.
