Abstract

A liquid fertilizer is prepared from urea and/or hydrolytic amino acid, potassium hydroxide, copper sulfate, iron sulfate, zinc sulfate, magnesium sulfate, manganese sulfate, calcium hydroxide, ammonium molybdate, cobalt chloride, borax, VC, acetyl salicylic acid and water through proportioning, liquefying and chelating reaction. Its advantages are low cost, high fertility and wide application range.

Description

technical field [0001] The invention relates to a chemical fertilizer, in particular to a multi-component compound liquid fertilizer and a production method thereof. technical background [0002] At present, traditional agricultural chemical fertilizers mainly include nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer, or their compound fertilizers according to the growth needs of field crops. With the rapid development of agricultural science and technology in the direction of high technology, the adjustment of agricultural structure has led to the rapid development of diversified production including special agricultural planting and horticultural flowers; the fertilization method has also developed from the traditional fertilization method to scientific and rational fertilization. Meet the growth needs of various crops. Modern agriculture needs fertilizers that include a combination of medium and micronutrient elements, which is the trend of modern agric...
