腐植酸类肥料是一种多功能的有机矿物肥料,腐植酸铵除含有氮素可供植物吸收以外,主要含有大量的有机质,具有较高的肥效,而且还有改良土壤和刺激植物生长发育等作用。配合施用腐植酸类肥料,可养地改土,同时能提高无机化肥的肥效。据各地试验,在通常情况下,每斤腐植酸铵可增产粮食1—2斤,每斤腐植酸氮磷复合肥可增产粮食2斤左右,每斤腐植酸氮磷钾复合肥可增产粮食3斤左右。施用条件腐植酸类肥料具有喜水特性,且适用性广,对各种作物都有不同程度的增产效果,但以施于水稻、蔬菜和麦类等效果比较明显。它对果树、瓜类还具有促进生长、改进品味、增加甜度的作用。
Humic acid fertilizer is a multi-functional organic mineral fertilizer, ammonium huminate in addition to containing nitrogen for plant absorption, the main contains a large number of organic matter, with higher fertilizer efficiency, but also improve the soil and stimulate plant growth and development effect. With the application of humic acid-based fertilizers, can raise soil, while improving the efficiency of inorganic fertilizers. According to tests all over, under normal circumstances, per kilogram of ammonium ferulic acid can increase grain production 1-2 pounds per kilogram of humic acid nitrogen and phosphorus fertilizer can increase grain production about 2 pounds per kilogram of humic acid NPK compound fertilizer can increase grain 3 About jin Application conditions Humic acid fertilizer has hi-water characteristics, and the applicability of a wide range of crops have different levels of yield, but applied to rice, vegetables and wheat and other effects more obvious. It is fruit trees, melons also have to promote growth, improve taste, increase the role of sweetness.
