Abstract

The invention relates to the technical field of fertilizer additives, in particular to a long-acting slow release fertilizer additive and a production method thereof. The additive consists of the following raw materials in parts by weight: 10-25 parts of dicyandiamide, 5-15 parts of thiourea, 7-15 parts of lignin, 8-20 parts of polyacrylamide and 25-70 parts of auxiliary material. A nitrogen fertilizer synergist, a phosphorus activator and a water retention agent are organically and skillfully combined, so that a synergic action is realized and a more remarkable effect is achieved. The obtained additive is added into various compound fertilizers, special fertilizers, BB (Bulk Blending) fertilizers and impulse fertilizers according to the proportion of 5-20 percent, so that various corresponding novel long-acting slow release and water retention fertilizer varieties can be produced without adding any equipment or changing the original production process. The additive has long-acting slow release and water retention and drought resisting functions. By adopting the additive, comprehensive agricultural benefits including increase in yield, increase in income, fertilizer saving and labor saving, good social benefits including resource saving and reduction in environmental pollution and good environmental and ecological benefits can be achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizer additives, in particular to a long-acting slow-release fertilizer additive and a production method thereof. Background technique [0002] With the increase of population and decrease of arable land, as well as the improvement of people's living standards, agriculture is required to continuously increase production and improve product quality. Fertilizer plays an important role in agricultural production, accounting for more than 30% of the factors that increase production. my country is a big country in the production and use of chemical fertilizers. Its output and usage rank first in the world, but the product quality needs to be further improved. The main problems are low fertilizer utilization rate, short fertilizer effect period and single function. Among them, the fertilization period of nitrogen fertilizer is only 30-50 days, while the fertilizer period of general crops is 90-120 days. T...
