Abstract

A humic acid fertilizer is produced by using humic acid from coal mine as main raw material and through mixing with azophoska and trace elements. It is produced into granulated fertilizer by the colloid of humic acid without needing of water and heating and its production of a simple and power-saving process with reduced internal antagonism. It has comprehensive nutrients and has slowly releasing effect, and one application can meet the need of plant's whole growth period. It is one cheap and efficient novel fertilizer.

Description

Full cold particle fertilizer of humic acid

The present invention proposes a kind of agricultural fertilizer and technology, promptly a kind of full cold particle fertilizer of humic acid and manufacturing process thereof.

At present, chemical fertilizer is the main fertilizer of China's agricultural.Huge effect has been played in China's agriculture production development, used chemical fertilizer for a long time, caused soil compaction, also become admitted facts.In order to address this problem, people have found multiple compound mixed fertilizer, and humic acid fertilizer is exactly wherein a kind of.Humic acids is the animals and plants remains, and through the organism that a series of physical chemistry of the earth processes form and accumulate, it can obviously improve the growth and development process of Soil structure and crop, therefore, has caused the attention of countries in the world.As far back as the fifties, Japan, USSR (Union of Soviet Socialist Republics) and East Bloc have just begun research and have used.Since the seventies, China has set up special association, carries out the development research of this respect, and multiple humic acid fertilizer has successively been released in various places.Through a large amount of experimental studies have found that, existing humic acid fertilizer exists the unreasonable and complicated two large problems of the course of processing of prescription.Unreasonable being meant of filling a prescription, the ratio of humic acids and various mixed fertilizers is unreasonable, the problem of cancelling each other occurred, and the seedling phenomenon is burnt in the also appearance that has.Said complex process refers to present various humic acid complex fertilizers and all adopts the granulation process that adds the water heating, promptly wastes energy, and makes the chemical combination modification to some extent of various fertilizer again, has increased the weight of inner antagonism.

It is complete to the objective of the invention is to develop a kind of nutrient, the rational humic acid fertilizer of filling a prescription, and propose a kind of simply energy-conservationly, reduce the complete processing of inner antagonism.

Above-mentioned purpose is realized by following technical scheme: (by weight) adopts primary humic acids 30-35 part, nitro humic acid 5-10 part, two ammonium 5-10 parts, urea 5-10 part, calcium superphosphate 10-12 part, vitriolate of tartar 4-5 part, zinc sulfate 0.5-1 part, silica flour 0.5-1 part is carried out high-speed stirring with humic acids earlier, add other various raw material blendings more successively after sticking, be squeezed into particulate state.

The humic acid fertilizer that adopts such scheme to make, reasonable ratio, nutrient is complete, and various raw materials mix, but each self-sustaining independently molecule or molecular grouping structure, thereby seldom producing antagonism and sex change, method for making is simple, saves water and energy.Prove that through 3 years simultaneous tests its fertilizer efficiency significantly improves, can keep soil from packing together effectively that there is tangible improving effect in the saltings, and have outstanding slow release effect, single-dose application can be satisfied the nutrient needs of crop whole growth phase.Be a kind of cheapness, new-type fertilizer efficiently.

By weight, get 35 parts of humic acidss, 5 parts of nitro humic acids, 10 parts of two ammoniums, 10 parts in urea, mistake

10 parts in calcium phosphate, 5 parts of vitriolate of tartar, 1 part in zinc sulfate, 1 part of silica flour.Start shaper, put into the humic acids high-speed stirring earlier and add other raw materials more successively, after stirring and the colloid of humic acids being become sticky, extrude strip, the cutting granulating can be packed.

Experiments such as vegetables, wheat, paddy rice, potato all obtain promising result.

Field experiment:

Corn, mu rate of fertilizer application 40-50 kilogram once applies.After measured, can make K fertilizer more, can make N, P, K supply time continue 100 days to the underground 3-4cm of infiltration.Soil sampling result is: pH value 5.91, and hydrolyzable nitrogen 13890.6mg/kg, rapid available phosphorus 4048.98mg/kg, available potassium 3020.81mg/kg, organic matter 37.36%, ripen in advance 5-7 days, drought resisting prolonged 7-10 days, increases production 15-20% compared with the control.

Claims

1, a kind of full cold particle fertilizer of humic acid, it is characterized in that: (by weight) adopts primary humic acids 3-5 part nitro humic acid 5-10 part, two ammonium 5-10 parts, urea 5-10 part, calcium superphosphate 10-12 part, vitriolate of tartar 4-5 part, zinc sulfate 0.5-1 part, silica flour 0.5-1 part is carried out high-speed stirring with humic acids earlier, add other various raw material powder mixings more successively after sticking, be squeezed into particulate state.
