Abstract
The present invention relates to a CO2 air fertilizer and a preparation method thereof. The CO2 air fertilizer is prepared by mixing solid sulphuric acid (the solid sulphuric acid is prepared from one portion of plant cellulose and 0.2 to 5 portions of commercial sulfuric acid) with a proper quality of carbonate. The present invention has low cost, safety and convenience, and is in accordance with the Chinese national state.
Description
The present invention relates to a kind of CO
2Gas fertilizer and preparation method thereof.
As everyone knows, in heliogreenhouse, enrich CO
2Gas fertilizer can significantly improve the output of crop.Prepare CO in the prior art
2The method of gas fertilizer has two classes, and the one, acid and carbonate reaction method, the one, organic compound combustion method.The former discloses " method for preparing carbon-dioxide gasfertilizer with solid acid " as CN1088562A, and it adopts bicarbonate of ammonia and solid sulphuric acid to react at normal temperatures and makes.This solid sulphuric acid is to adopt sulfuric acid that proportion is 60-80% in 1.15～1.25 silicate solutions and concentration and acid base indicator by sulfuric acid: silicate: indicator=1: 0.2～1.2: 0.01 (volume ratio) reacts and makes.Though this method is simple, safe ready, cost is higher in the preparation of solid sulphuric acid, and fertilizer efficiency is single.
The objective of the invention is to develop a kind of with low cost, safe ready, and the CO with multiple fertilizer efficiency
2Gas fertilizer and preparation method thereof.
CO of the present invention
2The preparation method of gas fertilizer comprises carbonate and solid sulphuric acid reaction, it is characterized in that described solid sulphuric acid preparation method forms sulfuric acid and plant cellulose reaction.It is that 0.2-5 industrial sulphuric acid doubly stirred 0.5-2 hour that plant cellulose is put into acid-resistant reactor adding weight, can obtain solid sulphuric acid.
Described plant cellulose can be wood chip, straw, straw, corn stalk etc.
The carbonate of black solid sulfuric acid powder and normal white that only needs when using in the greenhouse to pack in the plastics bag mixes can produce CO
2Gas fertilizer.Add water and can quicken CO
2Emit.
Described carbonate can be that lime carbonate, volatile salt are or/and bicarbonate of ammonia.
In order to reduce the influence of sulfate ion to soil, can in above-mentioned solid acid, add phosphoric acid salt, make a part of sulfate radical change into insoluble vitriol, phosphate transfection changes into soluble phosphate simultaneously, helps crop and absorbs.
In order to increase fertilizer efficiency and balance fertilizing, can in product, add sylvite.
CO of the present invention
2Gas fertilizer (by weight) is made up of 1 part of solid acid and 1 part of carbonate.Also can in above-mentioned prescription, add phosphoric acid salt and/or vitriolate of tartar 1-2 part (weight ratio).
The factor of created gase of above-mentioned gas fertilizer is all more than 30%.
The conspicuous advantage of the present invention is:
1. when the preparation solid sulphuric acid, adopt plant cellulose to make sorbent material, greatly reduce the cost of gas fertilizer.
2. storing safety, easy to use.
3. have compound fertilizer efficiency, the low carbon ammonium of fertilizer efficiency is changed into high thiamines of fertilizer efficiency or primary ammonium phosphate, utilization rate of nitrogen fertilizer is increased.
4. can not cause environmental pollution.
Embodiment 1
100 gram wood chips are put into the acid-resistant reactor that has agitator, add 200 gram industrial sulphuric acids then, continuously stirring 0.5-2 hour until forming the black solid powder.During use, 300 gram ammonium sulfate and above-mentioned black solid powder are mixed in a little plastic tank or Cans, can constantly emit CO
2Factor of created gase is more than 30%.
Embodiment 2
100 gram straws, 200 gram industrial sulphuric acids are made the black solid powder by the method for embodiment 1, mix with 100 gram phosphoric acid salt, 100 gram vitriolate of tartar, 100 gram salt of wormwood and 200 gram volatile salts during use, can emit CO
2, resistates is as soil application.
Embodiment 3
200 gram corn stalks, 100 gram industrial sulphuric acids are made solid-state black sulfuric acid by the method for embodiment 1, mix with 100 gram phosphoric acid salt, 100 gram vitriolate of tartar and 200 gram volatile salts during use, can emit CO
2, resistates is as soil application.
Embodiment 4
500 gram grass stalks, 100 gram industrial sulphuric acids are made black powder by embodiment 1 described method, during use, 100 gram phosphoric acid salt, 200 gram volatile salts are mixed, and can emit CO
2, resistates is as soil application.
Embodiment 5
300 gram weeds bars and 100 gram industrial sulphuric acid ammoniums are made black powder by the method for embodiment 1, mix with 100 gram volatile salts with 100 gram vitriolate of tartar during use, can emit CO
2, resistates is as soil application.
Embodiment 6
20 gram wood chips and 100 gram industrial sulphuric acids are made black powder by the method for embodiment 1, mix with 100 gram phosphoric acid salt, 100 gram vitriolate of tartar and 200 gram salt of wormwood during use, can emit CO
2, resistates is as soil application.
Claims (3)
1. CO
2Gas fertilizer is characterized by the solid sulphuric acid that is made of 1 part of wood chip, straw, straw, corn stalk or weeds bar and 0.2-5 part industrial sulphuric acid and the carbonate of 1-5 part and constitutes.
2. CO as claimed in claim 1
2Gas fertilizer is characterized in that described carbonate is lime carbonate, carbon ammonium and/or bicarbonate of ammonia.
3. CO as claimed in claim 1 or 2
