Liquid fertilizer capable of preventing soil-borne diseases and preparation method therefor

Abstract

The invention discloses a liquid fertilizer capable of preventing soil-borne diseases. The liquid fertilizer is prepared from the following raw materials, by weight, 36-40 parts of biogas residue mud, 5-7 parts of sodium potassium tartrate tetrahydrate, 6-8 parts of citric acid, 40-50 parts of corn germ meal, 15-19 parts of urea, 55-65 parts of dry chicken manure, 120-140 parts of waste livestock and poultry feathers, 6-7 parts of copper sulphate, 4-6 parts of ferrous sulphate, 4-5 parts of GM microbial preparations and a proper amount of water. Biogas residue mud, chicken manure and the like are employed in the raw materials of the liquid fertilizer and contain a lot of microbes with various kinds, the GM microbial preparations are added to raise the beneficial bacterium content, thus the liquid fertilizer becomes a microbe resource base, the soil microbial community structure can be adjusted after drip irrigation and spraying of the liquid fertilizer, the soil microbial diversity is raised, the soil micro-ecological environment is improved, the survival scope of plant pathogens is narrowed, and therefore the purpose of preventing soil-borne diseases is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a liquid fertilizer capable of preventing and treating soil-borne diseases and a preparation method thereof. Background technique [0002] As a large agricultural country in my country, agricultural production plays a vital role in the national economy, and fertilizer is an important factor affecting the output and quality of agricultural production. However, most fertilizers currently on the market have deficiencies in nutritional components, that is, while increasing yields, certain nutrients cannot keep up with demand, or focus on stimulating crop growth, leading to nutrient deficiencies, etc., resulting in poor stress resistance of crops and low yield. The reduction and quality decline cannot meet the needs of agricultural production at this stage. [0003] Compost extract refers to the water extract obtained by composting and decomposing organic materials extracted by d...
