Embodiment 1

[0013] Fully mix 300kg of fly ash and 100L of ethylene desulfurization waste lye; put the mixture into the reactor and heat at 120°C for 150 minutes. After the reaction, the sulfide in the obtained reaction residue mixture is reduced by 87%, the alkalinity is reduced by 55%, and the effective silicon content reaches 0.65%, and the reaction residue is taken out for use.

[0014] After stirring and mixing 250kg of reaction residue, 200kg of ordinary calcium raw meal, 400kg of urea and 150kg of potassium chloride, they are granulated by an extruder and dried into granules, which is the effective silicon-containing compound fertilizer A of the present invention.

[0015] The effective silicon-containing compound fertilizer prepared by the embodiment proves through the field evaluation of Gansu Academy of Agricultural Sciences: compared with applying the same amount of nitrogen, phosphorus, and potassium fertilizers, it has an effect of increasing the yield of wheat, and the increas...

Embodiment 2

[0017] Fully mix 300kg of fly ash and 50L of paper mill waste lye, add 250g of manganese oxide; put the mixture into the reactor, and heat at 120°C for 150 minutes. After the reaction, the sulfide in the mixture is reduced by 82%, the alkalinity is reduced by 50%, and the effective silicon content reaches 0.55%, and the reaction residue is taken out for later use.

[0018] Stir and mix 250kg of reaction residue, 250kg of ordinary calcium raw meal, 350kg of urea, and 150kg of potassium chloride, granulate through an extruder, and dry into granules, which is the effective silicon-containing compound fertilizer B of the present invention.

[0019] The effective silicon-containing compound fertilizer prepared by the embodiment proves through the field evaluation of Gansu Academy of Agricultural Sciences: compared with applying the same amount of nitrogen, phosphorus, and potassium fertilizers, it has an effect on increasing the yield of wheat, and the increase in yield reaches 4.8%...

Embodiment 3

[0021] Fully mix 300kg of fly ash and 150L of refinery desulfurization waste lye, add 250g of ferric oxide and 150g of copper oxide; put the mixture into the reactor and heat at 150°C for 150 minutes. After the reaction, the sulfide in the mixture was reduced by 81%, the alkalinity was reduced by 58%, and the effective silicon content reached 0.75%, and the reaction residue was taken out for later use.

[0022] 300kg of reaction residue, 300kg of general calcium raw meal, 300kg of urea, 100kg of potassium chloride, and 60kg of ammonium dihydrogen phosphate were mixed and stirred, granulated and dried into granules, which was the effective silicon-containing compound fertilizer C of the present invention.

[0023] The effective silicon-containing compound fertilizer prepared by the embodiment proves through the field evaluation of Gansu Academy of Agricultural Sciences: compared with applying the same amount of nitrogen, phosphorus, and potassium fertilizers, it has an effect of...

Abstract

The present invention relates to a kind of compound fertilizer containing effective silicon component, nitrogen fertilizer, phosphate fertilizer and potash fertilizer, and the compound fertilizer contains reaction residue of flyash treating waste alkali liquid 20-30%, nitrogen fertilizer 30-40%, potash fertilizer 10-20%, ordinary calcium superphosphate 15-30%. Experiment shows that the compound fertilizer has obvious effect of increasing wheat, corn and other crops and no any toxic side effect.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a compound fertilizer containing effective silicon, which utilizes industrial waste residues to produce the silicon fertilizer. Background technique [0002] Silicon is the fourth largest nutrient element needed for plant growth and has a significant effect on increasing crop yield. At present, there is a large area of ​​silicon-deficient soil in our country, which requires an average of 30-50 million tons of silicon fertilizer every year, but our country currently only has a production capacity of about 1 million tons, so the development and production of silicon fertilizer has huge market potential. At present, the silicon fertilizer production technology is mainly concentrated in the following fields: the technology developed by the Fujian Institute of Material Structure of the Chinese Academy of Sciences to use industrial waste residue and waste liquid to produce silicon fertilizer te...
