Humic acid urea and preparation process thereof

Abstract

The invention discloses humic acid urea and a preparation process thereof. The fertilizer comprises the following components by weight of 1000 kg: 420 kg of urea, 230 kg of lignite, 170 kg of bentonite and 130 kg of fluorspar powder. The humic acid urea has the advantages that physical and chemical properties of soil are improved, soil acidity and alkalinity is regulated, activity of soil microorganisms is promoted, activity of soil enzyme is improved to enable the soil to be loose, conditions of water, fertilizers, gas and thermal of the soil are regulated, development of root systems of plants is promoted, the speed of conversion of organic fertilizers into inorganic fertilizers in the soil is increased, plant chlorophyll is improved, plant photosynthesis is improved, resistance of cropscan be improved, soil caking, desertification and environment pollution due to application of inorganic chemical fertilizers in soil are prevented, physiological diseases of plants can further be prevented, the yield and quality of crops are improved 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 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
