Humic acid urea and preparation process thereof

Abstract

The present invention discloses a humic acid urea and a preparation process thereof, wherein 1000 kg of the fertilizer comprise 420 kg of urea, 230 kg of lignite, 170 kg of bentonite, and 130 kg of fluorite powder. According to the present invention, the humic acid urea has advantages of soil physical and chemical property improving, soil pH value adjustment, soil microorganism activity promoting, soil enzyme activity increase, soil loosening, soil water, fertilizer, gas and heat condition adjustment, plant root development promoting, soil organic and inorganic fertilizer conversion rate enhancing, plant chlorophyll increase, plant photosynthesis improving, crop resistance improving, prevention of soil hardening, sandification and environment pollution caused by application of excess inorganic fertilizer on soil, plant physiological disease prevention, crop yield improving, crop quality improving, and the like.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and in particular relates to humic acid urea and a preparation process thereof. Background technique [0002] At present, mankind is facing serious challenges of population growth, decrease of arable land, desertification, environmental pollution and water shortage, in order to meet people's growing needs for human survival. In agricultural production, it is necessary to provide sufficient quantity, high quality, pollution-free organic food and other agricultural by-products to protect the environment on which human beings live, which has become a worldwide urgent task. my country is a developing country with a lot of people and little land. Since the 1980s, with the implementation of the rural joint production contract responsibility system, the enthusiasm of farmers for production has been unprecedentedly high, and the increase in chemical fertilizers has been used as 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 urease 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
