Abstract

The invention discloses a fertilizer special for soybeans and a preparation method thereof. The method comprises the following steps: weighing, mixing and stirring citric acid, zinc sulphate powder, manganese sulphate powder, borax powder, ammonium molybdate powder and water at a reaction temperature of 80-90 DEG C for 40-60 minutes to prepare trace element chelate fertilizer liquid for spare; respectively weighing and stirring polyvinyl alcohol, cornstarch, dicyandiamide powder and water at a reaction temperature of 80-90 DEG C for 40-60 minutes to prepare bonding liquid for spare; uniformlymixing the trace element chelate fertilizer liquid and the bonding liquid according to a mass ratio of 1:4 for spare; respectively weighing, drying, crushing and screening pyrobituminous shale residue, calcium carbonate, magnesium sulphate, urea, diammonium phosphate and potassium sulphate by a screen of 100-120 meshes; uniformly mixing; adding the mixture to a pelletizer; and spraying the mixed liquid to granulate so as to obtain a the fertilizer special for soybeans. The invention has the advantages of comprehensive nutrients, good slow release, and the like, fully satisfies the growth needsof soybean and improves the yield and the quality of the soybean.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to a special fertilizer for soybeans and a preparation method thereof. 2. Background technology [0002] Soybean is the main oil crop in Northeast China. Traditional soybean fertilization is extremely unreasonable. It only focuses on the application of farmyard manure and phosphorus fertilizer, while ignoring the application of nitrogen and potassium fertilizers, let alone other medium and trace element fertilizers. Due to organic fertilizers The application of soybeans has been decreasing day by day, and the yield per unit area of ​​soybean has been low, generally 2250kg / hm 2 , which has a great potential to increase production, scientific and rational fertilization will be an important way to increase production. Therefore, according to the characteristics of soybean fertilizers, it is particularly urgent to develop a special fertilizer with comprehens...
