Description
Technical field
The present invention relates to crop material utilization and organic fertilizer production field, and in particular to a kind of crop material organic and inorganic compound
Hefei and its production method.
Background technology
Crop is China's staple food crop, stalk enormous amount.Crop material organic matter enriches, and from farmland, leads to
Everfermentation is decomposed, gives back in farmland, is to supplement the soil organism, soil nutrient, the important fertilizer source for improving soil texture.Cause
Crop material surface covers the reason such as coating of wax matter and cellulose, hemicellulose, content of lignin height, traditional crop stalk fermentation
Decomposed, the time is long, efficiency is low, and peasant is unwilling to use mostly;In recent years, as agricultural machinery is promoted, by straw in a manner of rotary tillage
Stalk, which directly smashes, turns over embedment field, although simple and easy to do, due to not passing through desinsection, sterilization, killing the processing such as weed seed, disease
Insect pest etc. easily remains, and has the popular potential risk of huge disease, insect pest, weeds, and few places have even occurred because of straw
Stalk rotary tillage direct returning to farmland and there is disease severe epidemic situation.Meanwhile although the various nutrient elements of crop material are complete, nitrogen,
The Main Nutrients constituent content such as phosphorus is too low, and course of fermentation is slow, limits straw utilization.
The content of the invention
It is an object of the invention to overcome shortcoming and deficiency existing for prior art, there is provided a kind of crop material organic-inorganic
Composite fertilizer and its production method.
The purpose of the present invention is achieved through the following technical solutions:
A kind of crop material composite organic-inorganic fertilizer, it is formulated comprising following raw material by weight:Crop material
1000 parts, water 400-600 parts, 98% concentrated sulfuric acid solution 200-300 parts, 98% concentrated nitric acid solution 200-300 parts, calcium magnesium phosphate
450-700 parts, urea 200-300 parts, potassium chloride 100-200 parts, diatomite in powder 60-100 parts.Can according to plant growth to nitrogen,
The demand status of the nutrients such as phosphorus, potassium, soil acid-base situation etc., suitably adjust sulfuric acid dosage, nitric acid dosage, calcium magnesium phosphate dosage,
Urea, potassium chloride dosage, or even the appropriate phosphoric acid of addition participate in stalk processing;Also can add other nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and in it is micro-
Secondary element fertilizer, to meet needs of the respective crop to nutrient element.It is above-mentioned 98% concentrated sulfuric acid solution 200-300 parts, 98% dense
Salpeter solution 200-300 parts are the limitations to sulfuric acid, the total dosage of nitric acid, if concentrated sulfuric acid solution, concentrated nitric acid solution concentration have change
Changing then parts by weight can keep total amount constant with respective change.Described crop material includes rice, wheat, sorghum, rape
Etc. the stalk of various crops.
The production method of above-mentioned crop material composite organic-inorganic fertilizer, comprises the following steps:
(1) crop material prepares:
Crop material is smashed into powdered segment, preferably 0.2-0.3 centimetres of powdered segment;
(2) crop material acid treatment:
The water for being formulated dosage is added in reactor, the concentrated sulfuric acid solution of formula dosage is added slowly, after stirring
Slowly the concentrated nitric acid solution of formula dosage is added, is stirred, and acid solution is heated to 40-55 DEG C;By matching somebody with somebody through pulverization process
The crop material of square dosage is added in reactor, is mixed, is mixed thoroughly, handles 12-24 hours, is substantially deepened to stalk color, straw
Stalk fully absorbs acid solution, material without free acid solution;
(3) calcium magnesium phosphate processing is added:
The calcium magnesium phosphate for being formulated dosage is added in reactor, fully mixed with the crop material fully handled through acid solution
Close, stir, mix, calcium magnesium phosphate is fully contacted with the acid solution inside crop material and its stalk, be stirred continuously mixed processing
12-24 hours, make fully to react, no longer rise to temperature;
(4) curing, drying process:
Crop material material by above-mentioned processing can reach the high temperature of 70-90 DEG C and the above, then by 12-48 hours
Stirring, curing, and appropriate heat drying process, make the moisture of material to less than 10%;
(5) urea, potassium chloride, diatomite in powder are added, further makes compound fertilizer:
Into by fully dry material (below moisture 10%), urea, potassium chloride, the silicon of formula dosage are added
Diatomaceous earth powder, mix, obtain crop material composite organic-inorganic fertilizer.
The present invention passes through strong acid and other common things rich in nutrient element using the stalk of various crops as primary raw material
Matter, it is thorough while the main matter structures such as cellulose, the lignin of the crop material surface waxs such as rice and difficult degradation are destroyed
The harmful substance such as germ is killed at bottom, makes full use of reaction heat, and largely supplements the nutrients such as nitrogen, phosphorus, be combined with organic and inorganic and
It is easy to the mode of production of automation, scale, batch production, produces crop material composite organic-inorganic fertilizer, both containing abundant organic
Matter, and the quick-acting nutrient elements such as N P and K containing abundance, it is possible to achieve long-acting nutrient is with available nutrient, supply crop nutrition content with using
Soil supports the coordinating and unifying of soil.
The present invention is had the following advantages relative to prior art and effect:
1st, it is sufficiently destroyed and has been degraded with difficult degradation composition of the acids such as sulfuric acid, nitric acid to crop material, and
Stalk material is passed through high-temperature process, can degrade rapidly so as to effectively facilitating and ensure stalk organic matter after field is applied and
It is absorbed by crops utilization.
2nd, combined with sulfuric acid, nitric acid, take into account product nutrient and using acid dilution heat release, oxidation reaction, acid-base reaction with
Release reaction heat, promotes windrow to enter high temperature, reduces energy consumption and cost;And by the processing such as strong acid and high temperature, crop material can
The pathogeny bacterium that can carry, worm's ovum, weed seed etc. have obtained thorough killing, ensure that with fertilizer safety.
3rd, the advantages of organic fertilizer is with quick-acting chemical fertilizer has been merged, the content of organic matter is enriched, and the essential nutrient contents such as N P and K are high,
Other nutrients are complete, balanced, comprehensive, and add diatomite in powder improved soil and absorption nutrient, not only can supply crop comprehensively and support
Point, available for base manure, top dressing etc., also with improved soil, delay the effects such as nutrients release, raising plant recovery of nutrient.
4th, crop material the like waste is taken full advantage of, no waste water and dregs are produced, turned waste into wealth, and fertilizer yield is high.
5th, simple production process, it is with short production cycle, it is especially suitable for batch production, large-scale production.
