Description

A kind of novel nitrate-based compound fertilizer

Technical field:

The present invention relates to composite fertilizer's production technical field, relate in particular to a kind of novel nitrate-based compound fertilizer.

Background technology:

Nitro-compound fertilizer is the chemical fertilizer new variety that develop rapidly in China in recent years, and the modification of agricultural ammonium nitrate in recent years has further promoted the research and development of nitro-compound fertilizer production technology.Nitro-compound fertilizer product safety after modification is reliable, easy to use, good environmental protection, nutrient content is high, both retain the fundamental characteristics of original ammonium nitrate, and can meet again the demand in traditional fertilizer market, can be used for base manure and the logical fertilizer of various cash crop, oil crops, dry crop, be widely used in various types of soil, be a kind of obvious effect of increasing production, have the fertilizer of good economic benefits and social benefit, the nitro-compound fertilizer of China is in the stage of developing rapidly at present.For example, but current existing nitro-compound fertilizer still exists a lot of defects, and dissolution rate is slow, residue is more, and fertilizer efficiency is poor, can not meet plant growth needs etc. completely.

Summary of the invention:

Technical problem to be solved by this invention is to provide a kind of novel nitrate-based compound fertilizer, to solve the problems of the technologies described above.

Technical problem to be solved by this invention realizes by the following technical solutions:

A kind of novel nitrate-based compound fertilizer of a kind of novel nitrate-based compound fertilizer, is characterized in that, is made up of following feed composition:

Ammonium nitrate: 30%-40% industry one ammonium: 8%-37%

Potassium sulfate: 28%-36% xanthohumic acid: 2%-5%

KOM stoste: 0.6%-0.8%.

A production method for novel nitrate-based compound fertilizer, is characterized in that: main technological steps is:

1) electronic scale automatic control feeds intake;

2) high speed disintegrator is pulverized raw material;

3) enter tablets press; (KOM stoste is agriculture series product concentrated liquid " synergistic agent " to add steam, KOM stoste; claim again fertilizer synergist; major ingredient is multiple amino acids and multiple organic-biological enzyme and soil improvement agent; contain various middle trace elements (boron, manganese, zinc, molybdenum, calcium, magnesium, iron, silicon etc.); be rich in the macroelement such as hydrogen, oxygen, nitrogen, sulphur, carbon, biological activity acid, amino acid, L-glutamic acid, Methionin, poly-aspartic-acid isoreactivity element and nitric nitrogen, water-soluble phosphorus, potassium, amount to kind more than 70.The effect of this material be improve crop quality, improve soil, in soil the nitrogen phosphorus potassium of mineralising again decompose, second stage employ.The fertilizer synergist of joint fertilizer, volume increase, raising quality, can directly obtain on market), through propylhomoserin tubular reactor, to react, the granulation time is 3-5 minute;

4) enter dryer, one section of oven dry, 25 minutes;

5) enter two sections of oven dry, 25 minutes, the raw material that goes out tablets press removed bucket elevator;

6) be promoted to vibration sieve, enter heat screening, temperature is at 80-90 ℃, and by upper strata screen cloth but can not enter secondary sub-sieve by the qualified particle of lower screen, the small-particle after sub-sieve enters returning charge scrapper conveyor and carries out returning charge;

7) by the finished particle of screen cloth enter cooling drum carry out one section cooling, 20 minutes;

8) enter two-step cooling, 20 minutes;

9) enter cold screening, temperature is at 30-40 ℃;

10) film, metering packing, check.

Nitrate-based compound fertilizer in the application generally makees base manure, every mu of consumption 30-50 kilogram of field crop, every mu of consumption 50-100 kilogram of the cash crop such as gourd, fruit and vegetable, seed manure isolation 6-8 centimetre.15-15-15 nitrate-based compound fertilizer also can be done fertile use of steady fruit of fruit tree, can avoid the prosperous length of branch, promotes bear fruit and alleviate shedding, can promote again bud differentiation, lays the first stone for yielding positive results the coming year.The nitrate-based compound fertilizer of 16-8-21 and two kinds of 18-9-18 generally topdresses, and is especially applicable to gourd, fruit and vegetable and does fruit-promoting fertilizer and use, and can spread fertilizer over the fields, ditch spread.General every mu of consumption 30-50 kilogram of field crop, every mu of consumption 50-100 kilogram of the cash crop such as gourd, fruit and vegetable; As make base manure, need join and execute high phosphorus type composite fertilizer or two ammoniums.

Precaution:

The first, nitric nitrogen easily outflows with water in paddy field, so nitro-compound fertilizer should not be applied in paddy field, but the use of can topdressing while falling to doing in paddy field.

The second, nitric nitrogen solubleness in water is very large, is very easy to absorb airborne steam and dissolve into mud shape, so please open before use bag, does not open while being finished after bag and please tighten packing sack, and be placed on shady and cool dry place and preserve.

Three, as stored improper caking, except knocking open with waddy, fast because of nitrate-based compound fertilizer dissolution rate, can also execute with water dissolution backlash, do not affect fertilizer efficiency.

The invention has the beneficial effects as follows:

The first, nitrate nitrogen content is high

Product nitric nitrogen and ammonium nitrogen that the application's method is produced substantially respectively account for half, nitric nitrogen >=7, and nitrate-based compound fertilizer contains two kinds of nitrogenous sources simultaneously, and crop growing state is more strong compared with common S-based compound fertilizer, and output is higher, and quality is better.

The second, use safer

Crop can absorb nitric nitrogen in a large number, can not damage crop, and unnecessary nitric nitrogen is stored in vacuole for subsequent use, and excessive absorption meeting damages crop unlike ammonium nitrogen.

Three, crop quality is better

Ammonium nitrogen can suppress the absorption of crop to calcium ions and magnesium ions, and nitric nitrogen and ammonium nitrogen antithesis, can promote the absorption of crop to calcium ions and magnesium ions greatly, reduces the physiological disturbance that crop is caused because of calcium deficiency magnesium deficiency, improves crop keeping quality and quality.

Four, applied widely

A, nearly all dry crop are all liked nitric nitrogen; B, be particularly suitable for melon, really, vegetables, peanut etc. are to better effects if on the crops such as on the happiness such as fear-chlorion crop and soybean, peanut, rape, shallot, garlic, Chinese cabbage and the wild cabbage sulphur crops such as the large crop of the demand of the elements such as calcium magnesium and tealeaves, potato, sugarcane and saltings, booth; The nitre sulfenyl product that c, the application provide meets the fertile standard of tobacco completely, can on tobacco, use.

The application's production method, beneficial effect has:

1) equipment does not lump, do not stop up, can realize long-time continuous stable operation.

2) lectotype selection coupling is reasonable, production intensity is large, compared with main process equipment of the same type, more than throughput improves 25%-50%.

3) technical process is succinct, and maintenance operation and production management facility can realize tail gas qualified discharge and clean carrying out production strictly in line with rules and regulations.

4) investment operation is more economical, and compared with of the same type, investment in fixed assets can reduce more than 30%, and operation coal consumption, power consumption, steam consumption can reduce more than 25%, and fertile production cost per ton can reduce 50-100 unit.
