Lignin organic slow-release liquid fertilizer for wheat and preparation method thereof

Abstract

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.

[0002] my country is a big wheat producing country. Wheat plays a very important role in the national economy. Chemical fertilizers are needed in the process of planting wheat. At present, inorganic fertilizers are mostly used, but long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil quality deterioration. Hard, thus affecting the growth of wheat, the promotion effect on wheat growth is not obvious, and for organic fertilizer, although it is rich in organic matter, the release of nutrients is slow, the absorption of wheat is slow, the fertilizer efficiency is low, and the effective balance between various effective nutrients cannot be achieved

At present, the method of increasing nitrogen fertilizer is generally used in rural areas to increase wheat yield. However, long-term large-scale application of inorganic nitrogen fertilizer will exceed the absorption capacity and soil retention capacity of crops, resulting in soil nitrate nitrogen leaching into the deep soil layer with precipitation and irrigation water, below the root zone. Soil accumulation, causing nitrogen leaching
