Preparation method of grape slow-release fertilizer for improving soil and improving quality

Abstract

The invention discloses a preparation method of a grape slow-release fertilizer for improving soil and improving quality. The preparation method comprises the following steps of stirring coffee residue and a potassium hydroxide solution, filtering, drying, carbonizing, grinding, adding lignocellulose and an aqueous solution of sulfuric acid, stirring, centrifuging, adding oxalic acid and water, dispersing by ultrasonic waves, filtering, drying, and crushing, so as to obtain a first material; grinding rice husk carbon powder, sugarcane residue, corn cob powder, withered coal, coal gangue, medical stone powder, and fermented cottonseed meal, adding a sodium hydroxide solution, stirring, filtering, drying, and crushing, so as to obtain a second material; uniformly mixing the fermented soybeanmeal, rice bran, sea bird manure, and kiln ash potassium fertilizer, adding corn oil and water, stirring, adding high temperature-resistant alpha-amylase, stirring at room temperature, deactivating,adding monopotassium phosphate, triple superphosphate, potassium nitrate, urea, the second material, EDTA (ethylene diamine tetraacetic acid) chelating zinc, ammonium molybdate, [Fe(H2NCONH2)6](NO3)3,and the first material, adding glutaraldehyde, stirring, adding microcrystalline cellulose, uniformly stirring, granulating, and drying, so as to obtain the grape slow-release fertilizer for improving soil and improving quality.

Description

technical field [0001] The invention relates to the technical field of grape slow-release fertilizers, in particular to a preparation method of grape slow-release fertilizers capable of improving soil quality. Background technique [0002] Grape (scientific name: Vitis vinifera L.) is a woody vine of the family Vitis genus, with cylindrical branchlets, longitudinal ribs, glabrous or sparsely pilose, oval leaves, dense or sparse panicles, well-developed base branches , the fruit is spherical or oval, the flowering period is April-May, and the fruiting period is August-September. Grapes are a famous fruit, eaten raw or made into raisins, and brewed. The leftovers after brewing can be used to lift wine and eat acid. Grape planting has played a positive role in increasing farmers' income. At present, due to the excessive application of chemical fertilizers in the planting process, the soil is severely compacted, and the grapes produced have high nitrate content, low sugar conte...
