Abstract

The invention relates to a humic acid water-retention sustained and controlled organic-inorganic fertilizer made from waste of sugar refineries and alcohol plants. The fertilizer comprises active humic acid, a water retention agent, an organic fertilizer and an inorganic fertilizer. Moreover, a fertilizer composition can contain a sterilizing agent. The fertilizer composition disclosed by the invention can effectively promote rooting of crops and increase the yield.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a humic acid-type water-retaining slow-release and controlled-release organic-inorganic fertilizer utilizing waste from sugar factories and alcohol factories. Background technique [0002] Sugar factory alcohol waste liquid is a kind of acidic waste liquid left after alcohol is prepared with residual molasses from sugar cane sugar factories, beet sugar factories and other sugar factories. This type of waste liquid contains a large amount of organic matter and beneficial elements. my country currently discharges millions of tons of this waste liquid every year, which has caused serious environmental pollution problems. At present, the main utilization method of this waste liquid is still direct irrigation. On the one hand, this extensive application method is not conducive to the effective utilization of nutrients; on the other hand, due to transportation and other restrictions, this ap...
