The invention relates to a
lignin organic slow-release liquid
fertilizer for wheat and a preparation method thereof, belonging to the technical field of organic slow-release fertilizers. The
lignin organic slow-release liquid
fertilizer for wheat is prepared from the following raw materials in parts by weight: 20-35 parts of
lignin, 10-20 parts of a high molecular
polymer, 2-8 parts of
cellulose mud cakes, 3-7 parts of organic
abamectin, 10-15 parts of acidic
hemicellulose liquid, 10-15 parts of alkaline hemicelluloses liquid, 8-13 parts of a
nitrogen fertilizer, 10-15 parts of a
phosphorus fertilizer, 12-16 parts of a
potassium fertilizer, 5-10 parts of
nitric acid, 10-20 parts of
plant cytokinin, 16-20 parts of
zeolite powder, and 5-10 parts of
activated carbon. The
raw material components in the lignin organic slow-release liquid fertilizer for wheat coordinate with one another to achieve a synergistic action, the
nutrient proportions of the raw materials consider the total
nutrient requirement in the whole growth period of the wheat to ensure that the
nutrient elements required by the growth and development of the wheat can be comprehensively supplied, so that the lignin organic slow-release liquid fertilizer is complete in
nutrition, more in function, high in comprehensive
fertility and great in potentiality and is special for the wheat.
