Problems solved by technology

However, the organic substances in the coating material are not resistant to high temperature, and a series of chemical reactions occur during the addition process, resulting in the formation of other substances on the surface, affecting the appearance of the product, easily causing the product to fade, numb, harden, etc., resulting in unstable product quality , and the product is easy to pulverize, disintegrates slowly, and the fertilizer effect cannot be guaranteed

Abstract

The invention provides a multifunctional stable coated fertilizer, which mainly comprises the following components (by weight): 900-1000 parts of a fertilizer nutrient raw material, 20-40 parts of a bonding aid, 40-60 parts of ammoniated humic acid, 10-30 parts of biochar, 1-10 parts of a microbial agent, and 1-10 parts of other auxiliaries. The multi-functional stable coated fertilizer of the invention can effectively solve the problem of surface fading of the fertilizer by adding the modified humic acid-ammoniated humic acid; and the carbon-nitrogen ratio can be regulated with the cooperation of biochar, and the survival rate of bacillus microorganisms can be raised. The appearance of the fertilizer can be improved, and fertilizer efficiency of the fertilizer also can be enhanced.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a multifunctional and stable coated fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an important means of production for increasing crop yield and harvest. In recent decades, due to the widespread application of chemical fertilizers, my country's grain production has doubled. However, the long-term partial application of chemical fertilizers in farmland has deteriorated the soil structure, unbalanced nutrients, and drastically reduced microbial populations, resulting in low fertilizer use efficiency and a decline in the quality of agricultural products. [0003] Applying biotechnology to develop and develop microbial fertilizers is one of the needs and choices for the sustainable development of modern agriculture. It has a history of nearly 50 years in China. It can not only fix the nitrogen in the atmosphere, dissolv...
