Granular CO2 gas fertilizer and its preparation method

Abstract

The present invention discloses a granular CO2 gas fertilizer and its preparation method. It is characterized by that it uses one limestone as main raw material, and adopts the processes of pulverizing, adding pulverized ammonium phosphate and sulfur, mixing them uniformly and high-pressure granulating so as to obtain the invented granular CO2 gas fertilizer. Its composition contains limestone 40%-50%, ammonium phosphate 30%-35% and sulfur 15%-30%. It is simple in production process, can make the cover-cultured plant strongly grow, can resist diseases and increase yield, and can provide enough CO2 for plant in the winter.

Description

(1) Technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a granular carbon dioxide gas fertilizer and a preparation method thereof. (2) Background technology [0002] At present, with the development of the "vegetable basket" project, the so-called covered cultivation such as solar greenhouse and culvert cultivation is also developing rapidly. In order to make the plants under covered cultivation thrive, people have adopted methods that require more carbon dioxide, such as using steel cylinders to Release directly, or use carbon dioxide generator, or use dry ice, or use carbonate to react with acid, or use methods such as hydrocarbon combustion. Cause greater difficulty, and some of the methods cost more. (3) Contents of the invention [0003] The object of the present invention is to provide a kind of solution that is conducive to solve the problem that covered cultivation plants can grow vigorously, resist diseases and incr...
