Abstract
The present invention discloses a calcium-magnesium-phosphorus fertilizer in the form of granules. The present calcium-magnesium-phosphorus fertilizer presents powder shape and is easily dispersed with wind in use; thus, environment is polluted and the fertilizer is wasted because of dispersion. In the present invention, the calcium-magnesium-phosphorus fertilizer is prepared into granular shape by adding magnesium sulfate solutions for mixture; thus, the calcium-magnesium-phosphorus fertilizer in the form of granules is easily dissolved in contact with water after being used and has the advantages of easily released effective component, quick absorption by crops, convenient use and long fertilizer effect. The addition dosage of the added magnesium sulfate is few; the original component proportion and the structure of the calcium-magnesium-phosphorus fertilizer are not changed; the mixture of the magnesium sulfate the calcium-magnesium-phosphorus fertilizer has synergistic function; the operation is easy because of the easily grasped quality standards.
Description
One, technical field
What the present invention relates to is a kind of granular calcium magnesium-phosphorus fertilizer.
Two, background technology
Fused(calcium magnesium)phosphate is the chemical fertilizer of using always, uses extensively, and its commodity property is Powdered, thereby dust can fly away with the wind when using, and causes environmental pollution, and fertilizer scatters and disappears and causes waste again, and has increased labour intensity.Present solution is to add water before using or mix particulate state with the material of humidity to use.This method obviously is not the ideal method, and the particle that this method is made is done easily caking of back, and composition is difficult for disengaging, and the various component contents in the fertilizer are inaccurate, and quality standard is difficult for grasping.Publication number is 1067045 Chinese invention patent application; a kind of particulate state phosphate fertilizer and preparation method thereof is disclosed; its major technique feature be with the attapulgite raw ore as binding agent, mix the attapulgite original ore powder in process of production, in tablets press, prepare particle after the mixing together.Though this method also can prepare particulate state phosphate fertilizer, owing to added more additive, changed the content of various compositions in the original fertilizer, when using, also change the constituent structure of soil in addition, thereby still existed certain deficiency.In addition yet there are no the report of ideal granular calcium magnesium-phosphorus fertilizer.
Three, summary of the invention
Purpose of the present invention prepares a kind of granular calcium magnesium-phosphorus fertilizer exactly, prepares the existing deficiency of granular calcium magnesium-phosphorus fertilizer to overcome Powdered fused(calcium magnesium)phosphate and to have the preparation method now.
For achieving the above object, the present invention has taked such measure, and a kind of granular calcium magnesium-phosphorus fertilizer is prepared from ordinary method by the following weight proportion raw material:
Fused(calcium magnesium)phosphate 1 weight part
Mix Adlerika 0.11-0.15 weight part
Described mixing Adlerika refers to: sal epsom is dissolved in the solvent, in the time of 50-60 ℃, detect the relative proportion of solution, when degree Beaume dissolve in during for 13-20 account for the carboxymethyl cellulose that solvent ratios is 0-1.5% after the solution of gained, described solvent refers to water.
The preferred version of described mixing Adlerika refers to: sal epsom is dissolved in the solvent, in the time of 50-60 ℃, detect the relative proportion of solution, when degree Beaume dissolve in during for 13-20 account for the carboxymethyl cellulose that solvent ratios is 0.2-1.5% after the solution of gained, described solvent refers to water.
Described sal epsom, carboxymethyl cellulose are commercial sulphuric acid magnesium and industrial carboxymethyl cellulose.
Take the present invention of above-mentioned measure, use sal epsom as additive, under its effect, fused(calcium magnesium)phosphate can be prepared into particle, uniform particles, solid, in transportation, be difficult for pulverizing, use well, use the back and contact easily dissolving with water, effective ingredient easily discharges, crop absorbs fast, and easy to use, fertilizer efficiency is lasting.The sal epsom addition that is added is few, does not change fused(calcium magnesium)phosphate original composition ratio and structure, with fused(calcium magnesium)phosphate synergy is arranged, and quality standard is easily grasped, and implements easily.
