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 fertilizer particle strength, a granular fertilizer, a preparation method thereof and a fertilization method of the granular fertilizer. The synergistcomprises the following components in percentage by weight: 20-50% of bentonite, 40-60% of modified metal silicate and 10-20% of polyvinyl alcohol. The granular fertilize comprises a granular fertilize matrix component, the granular fertilizer also comprises the synergist, and the synergist and the granular fertilizer matrix component form a mixture. The granular fertilizer has high internal forceof particles, high strength, no powder falling from the particles, good anti-caking effect and no bad phenomena such as crushing, slot blocking and the like. The preparation method of the granular fertilizer is easy to control and mild in conditions, can effectively ensure the stable performance of the prepared granular fertilizer particles, effectively improves the preparation efficiency and reduces the production cost.

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...
