Abstract

The invention discloses a special corn fertilizer and a preparation method thereof. The method comprises the following steps: weighing, mixing and stirring citric acid, zinc sulphate powder, copper sulphate powder, borax powder and water at a reaction temperature of 80-90 DEG C for 40-60 minutes, weighing citric acid, zinc sulphate powder, copper sulphate powder, borax powder and water, mixing, and stirring at a reaction temperature of 80-90 DEG C for 40-60 minutes to prepare trace element chelate fertilizer liquid for spare; weighing polyvinyl alcohol, cornstarch, dicyandiamide powder and water, mixing and stirring at a reaction temperature of 80-90 DEG C for 40-60 minutes to prepare bonding liquid for spare; uniformly mixing 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, furfural residue, calcium carbonate, urea, diammonium phosphate andpotassium chloride by a screen of 100-120 meshes; uniformly mixing; adding the mixture to a pelletizer; and pelletizing in the mixed liquid so as to obtain the special corn fertilizer. The invention has the advantages of comprehensive nutrients, good slow release, and the like, fully satisfies the growth need of corn and improves the yield and the quality of corns.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to a special fertilizer for corn and a preparation method thereof. 2. Background technology [0002] Corn is a high-yielding crop, its sown area and total output rank third in the world after rice and wheat. Corn is not only a food crop, but also an economic and feed crop. It is an important raw material for hundreds of valuable industrial products. , occupies an extremely important position in the national economy. Although maize is a high-yielding crop, its potential for increasing yield is still great. Scientific and rational fertilization will be an important way to increase yield. Therefore, according to the characteristics of corn fertilizer needs, it is particularly urgent to develop a special fertilizer with comprehensive nutrients and good slow-release properties, which can fully meet the nutrient needs of corn, maximize the fertilizer effect, a...
