Abstract

The invention discloses a synergist for a composite / compound fertilizer, as well as a preparation method and a using method thereof. The synergist comprises N-(N-butyl)thiophosphoric triamide, 1-methylaminoformyl-3-methylpyrazole and ammonium humate. According to the synergist, the polar characteristics of molecular structures of the three components are sufficiently utilized to prepare powder with specific fineness, and the powder can effectively coat the surface of composite fertilizer or compound fertilizer. When the synergist is used, adsorption coating on the particle surface can be completed by means of simple and mechanical mixing. The synergist can be used for effectively prolonging the fertilizer efficiency, improving the utilization, can be sufficiently mixed with fertilizer particles without consuming or causing adhesion of fertilizer particles, and is simple to operate and beneficial to popularization.

Description

technical field [0001] The invention relates to a composition, in particular to a compound / compound fertilizer synergist and a preparation method and application method thereof. Background technique [0002] Chemical fertilizers play an important role in agricultural production, which is conducive to the harvest and increase of crops. Commonly used fertilizers are nitrogen, phosphorus and potash. In order to increase fertilizer efficiency and save costs, multiple fertilizers are often used in combination to prepare compound fertilizers or compound fertilizers. The simple use of chemical fertilizers has the disadvantages of rapid decomposition of fertilizers and a short period of fertilizer (only a few weeks), which cannot meet the needs of crops for more than 100 days of fertilizer growth. Frequent fertilization in order to prolong the fertilizer effect will not only significantly increase production costs. Waste, excessive accumulation of decomposition products of fertili...
