Heat insulation and fertilizer conservation liquid fertilizer and preparation method therefor

Abstract

The invention discloses a heat insulation and fertilizer conservation liquid fertilizer. The liquid fertilizer is prepared from the following raw materials, by weight, 38-42 parts of rape straw carbon powder, 6-8 parts of whey powder, 5-7 parts of potassium pyrophosphate, 9-13 parts of triple superphosphate, 55-65 parts of rice bran, 40-46 parts of vinegar residues, 90-110 parts of waste livestock and poultry feathers, 4-5 parts of copper sulphate, 6-7 parts of ferrous sulphate, 5-6 parts of GM microbial preparations and a proper amount of water. Through addition of rice bran, straw carbon powder, vinegar residues and the like, the organic colloid content in the fertilizer is raised, the adsorption surface of soil can be increased greatly after long-term usage, soil particles are cemented, a stable granule structure is formed, the effects of soil on water retention, fertilizer conservation, ventilation and the like are raised, crop root growth is enhanced, the temperature buffer capability of soil is raised through a lot of organic humus, day and night temperature difference is lowered, and the crop growth environment is optimized.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a liquid fertilizer for heat preservation and fertilizer preservation 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 differ...
