Liquid organic fertilizer and preparation method

Abstract

Liquid organic fertilizer comprises the following ingredients: 19% of soluble nitrogen-phosphorus-potassium raw material, 30% of humic acid agent, 20% of alginic acid agent, 10% of amino acid agent, 10% of fulvic acid potassium agent, 5% of soil conditioner and 6% of chelated medium trace element agent. The liquid organic fertilizer has the benefits that the liquid organic fertilizer can quickly supplement soil nutrition, allows a plant root system to be capable of directly absorbing organic matter and chelated medium trace elements, improves crop quality, avoids physiological diseases of crops, is green and safe, achieves agricultural production and income increase, is convenient to use and pollution-free, has good prevention and treatment effects on continuous cropping diseases and soil-borne diseases, breaks soil hardening, improves a soil microorganism ecological environment, increases the organic matter, fixes nitrogen, dissolves phosphorus and potassium, reduces the usage amount of inorganic fertilizer and protects the environment.

Description

technical field [0001] The invention relates to a liquid organic fertilizer containing animal and vegetable protein and a production method thereof, in particular to a liquid organic fertilizer compounded with various compound organic acids and trace elements in a chelated state and a preparation method thereof. Background technique [0002] For a long time, the large-scale application of chemical fertilizers has destroyed the structure of the soil and the soil microenvironment. Food safety is worrying. The status of organic fertilizers in agricultural production has also been paid more and more attention. The proportion of organic fertilizers in agricultural production will decrease getting bigger. [0003] The livestock and poultry manure produced by large-scale breeding enterprises is partially processed and produced into industrial organic fertilizers for large-scale application. However, the salt, heavy metals and antibiotics remaining in the livestock and poultry manur...

Problems solved by technology

However, for crops in the vigorous growth period and intensive production period, the supply of organic matter and trace elements in the soil obviously cannot keep up with the growth rate of the crops, resulting in a decline in crop yield and quality, and even physiological diseases

[0005] Although the liquid organic fertilizers currently available on the market can meet the growth needs of some crops, some liquid organic fertilizers still have problems such as single organic acid content, low organic matter content, a large number of harmful elements, and unreasonable formulas, which cannot fully meet the needs of agricultural production. Production needs
