preparation example Construction

[0040] Based on the above-mentioned granular fertilizer, the embodiment of the present invention also provides a preparation method of the above-mentioned granular fertilizer. The preparation method technology of described granular fertilizer is as figure 1 As shown, it includes the following steps:

[0041] S01: Mix the synergist mentioned above with the components of the granular fertilizer base to obtain a fertilizer mixture;

[0042] S02: Granulating the fertilizer mixture.

[0043] Wherein, the synergist and the composition of the granular fertilizer base in the step S01 are as described above in the granular fertilizer example, specifically, the synergist is the synergist described above. The granular fertilizer base component may be a fertilizer base component suitable for preparing granular fertilizer. In one embodiment, the synergist is mixed with the granular fertilizer base components at a ratio of 3wt%-6wt% of the synergist in the granular fertilizer.

Abstract

The invention provides a synergist for enhancing the strength of fertilizer granules, a granular fertilizer, a preparation method thereof, and a fertilization method of the granular fertilizer. The synergist includes the following components in weight percentage: 20%-50% of bentonite, 40%-60% of modified metal silicate, and 10%-20% of polyvinyl alcohol. The granular fertilizer includes granular fertilizer base components, the granular fertilizer also includes the synergist of the present invention, and the synergist forms a mixture with the granular fertilizer base components. The granule fertilizer of the present invention has high granule internal force and high strength, and the granule does not shed powder, has good anti-caking effect, and does not cause bad phenomena such as broken and blocked grooves. The process conditions of the granular fertilizer preparation method are easy to control, the conditions are mild, and can effectively The performance of the prepared granular fertilizer is ensured to be stable, the preparation efficiency is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a synergist for enhancing the strength of fertilizer granules, a granular fertilizer containing the synergist, a preparation method thereof, and a fertilization method of the granular fertilizer. Background technique [0002] With the acceleration of the land transfer process across the country and the exacerbation of the rural labor force loss caused by farmers migrating to cities, the state vigorously promotes large-scale agricultural production, and the level of agricultural mechanized production continues to improve. According to the latest statistics, the comprehensive mechanization level of crop cultivation in China was 45.8% in 2008, and 65.2% in 2016, an increase of 19.4% over 2008. In recent years, the state has increased subsidies for agricultural machinery, and agricultural mechanized production is accelerating. Agricultural mechanization includes machine fertiliz...
