Humic acid urea and preparation technology thereof

Abstract

The invention discloses a humic acid urea and a preparation technology thereof. The humic acid urea (1000 kilograms) comprises 420 kilograms of urea, 230 kilograms of brown coal, 170 kilograms of bentonite, and 130 kilograms of fluorspar powder. The humic acid urea can improve the physical and chemical properties of soil, adjust the pH value of soil, increase the activity of enzymes in the soil, loosen the soil, adjust the water, fertilizer, gas, and heat situations of soil, promote the growth of plant roots, enhance the conversion rate of inorganic fertilizers and organic fertilizers in the soil, increase the plant chlorophyll, strengthen the photosynthesis of plants, and improve the resistance of crops. Moreover, the soil hardening, desertification, and environmental pollution caused by excess inorganic fertilizers are prevented, the plant diseases are prevented, and the output and quality of crops are both increased.

Description

Technical field [0001] The invention belongs to the field of agricultural fertilizers, and specifically relates to a humic acid urea and a preparation process thereof. Background technique [0002] At present, mankind is facing serious challenges such as population growth, reduction of arable land, desertification, environmental pollution and water shortage, for the survival of mankind and to meet the increasing demands of people. In agricultural production, it is necessary to provide sufficient quantity, high-quality, pollution-free organic food and other agricultural and sideline products to protect the environment on which mankind depends. This has become a worldwide urgent task. my country is a developing country with more people and less land. Since the 1980s, with the implementation of the rural joint production contract responsibility system, farmers’ enthusiasm for production has risen unprecedentedly. Increasing the application of chemical fertilizers has been the main m...

Problems solved by technology

But the disadvantages are fast volatilization, low utilization rate, less absorption by plants, and impact on the environment

Urea is an ammonium nitrogen fertilizer. The nitrogen contained in it needs to be decomposed and converted into ammonium nitrogen by the urea enzyme secreted by urea bacteria before it can be absorbed by plants. The utilization rate is generally 30%-40%. Disadvantages of volatilization, deposition, environmental pollution, burning seedlings and leaves, and compacting soil
