Abstract

The invention discloses a production method of long-acting ammonium phosphate salt slow release fertilizer granules. The production method is characterized in that a phosphorous material, a magnesian material, a calcareous material, ammonia water and the like react to generate MgNH4PO4.xH2O and CaNH4PO4.xH2O which are insoluble in water but soluble in acid; acid rain contains a trace amount of acid radical ions such as sulfate ions and nitrate ions, which can be slowly dissolved MgNH4PO4.xH2O and CaNH4PO4.xH2O and corrode crop waste particles in the granules; various absorbable nutritional elements such as N, P, K, Ca, Mg, C and H are provided for plant growth for a long time; harmful ions in the acid rain are consumed; a beneficial way is provided for recycling of crop wastes.

Description

technical field [0001] The invention relates to the technical field of fertilizer production for plants and vegetation soil. Background technique [0002] Vegetation soil is a necessary material for urban traffic landscape and road slope greening. For urban traffic landscape green belts, manual maintenance such as watering and fertilization is easy to achieve. For traffic green belts and road slope green vegetation far away from the urban area, artificial spreading It is very difficult to maintain chemical fertilizers, etc., and the commonly used chemical fertilizers are basically fast-acting fertilizers. The short-term effect is obvious, but the validity period is short. After a period of time, the chemical fertilizers that have not been absorbed by plants will decompose and volatilize, losing their efficacy, and it is difficult to control the amount of fertilizer accurately. The amount of fertilizer applied is insufficient , Vegetation will affect the normal growth due to ...
