Fulvic acid organic fertilizer and preparation process thereof

Abstract

The invention relates to a fulvic acid organic fertilizer and a preparation process thereof. The fulvic acid organic fertilizer comprises the following available nutrients by weight: 2 to 6% of nitrogen, 2 to 6% of phosphorus, 2 to 6% of potassium, 8 to 12% of amino acid, 30 to 40% of organic matter, 10 to 20% of fulvic acid and 5 to 10% of a plant-growth regulator. The humic acid organic fertilizer contains strong-activity organic components which can activate soil and enables microbes to be multiplied in quantity and to have enhanced vitality, and also contains a plurality of inorganic quick-acting nutrients; the humic acid organic fertilizer exerts fertilizer effect and has a plant growth regulating function; and when applied to soil, the humic acid organic fertilizer can immediately provide quick-acting nutrients needed by plant growth, improves soil and soil fertility, exerts especially obvious effect on uncultivated land, saline land and barren land, and is capable of adsorbing and chelating heavy metal ions in soil, mitigating soil contamination, realizing sustained, high-efficiency and pollution-free production of agriculture, preventing pollution to agricultural products and enhancing the quality of agricultural products.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and in particular relates to a fulvic acid organic fertilizer and a preparation process thereof. Background technique [0002] In recent years, with the improvement of farmers' living standards, farmers have increasingly neglected the use of organic fertilizers. Agricultural production basically uses convenient, industrially produced chemical fertilizers, resulting in soil structure damage, reduced production potential, fragile ecological environment, and more serious It also pollutes the soil and agricultural products and increases agricultural production input, which runs counter to the country's advocated development of ecological agriculture and the realization of pollution-free production. Although traditional farmyard manure has many advantages, it is dirty, smelly, and difficult to produce, transport, and apply. Problems such as laborious and laborious, make the farmer not ...
