Abstract
The present invention relates to humic acid complex urea and a production process thereof. The humic acid complex urea is mainly prepared from 465 to 550 portions of urea and 35 to 45 portions of humic acid. The production process comprises the following steps: the humic acid is dissolved into 120 to 160 portions of water at a temperature of no higher than 25 DEG C in a reaction kettle A; the urea is dissolved into 280 to 390 portions of water at a temperature of no higher than 40 DEG C in a reaction kettle B; a humic acid solution dissolved in the reaction kettle A is added to the reaction kettle B; phosphoric acid is slowly added; the pH value is continuously detected until the pH value is between 5 and 7, so the humic acid complex fertilizer is manufactured. When the humic acid complex fertilizer is applied, the humic acid complex fertilizer is dissolved to form biuret. After application, the humic acid complex fertilizer is easy to absorb by plants; the absorption speed is high, and the effects are obvious. The humic acid complex urea is particularly suitable for a dripping and spraying irrigation cultivation mode which is currently and widely applied.
Description
Technical field
The present invention relates to a kind of complexing humic acid liquid fertilizer and production method thereof, especially a kind of fulvic acid complex liquid fertilizer and production method thereof.
Background technology
Mostly present urea in use is to use with solid-state, use under the more and more wider situation at spray drip irrigation technique at present, and all be that urea directly is dissolved in the water, dissolved speed is slow, does not also form biuret when using, slow by plant absorbing, and it is slow therefore to take effect.
Summary of the invention
Be easy to by plant absorbing, fast fulvic acid complex liquid fertilizer and the production method thereof of absorption rate after the object of the present invention is to provide a kind of using.
Fulvic acid complex liquid fertilizer of the present invention is mainly formed by the preparation of raw material of following weight part:
Urea is 465-550 part, humic acids 35-45 part.
Above-mentioned humic acids is preferably xanthohumic acid, is preferably DD-xanthohumic acid sylvite.
Its production technique is as follows:
In the A reactor, add cold water 120-160 part of≤25 ℃, add humic acids and constantly stirring;
In the B reactor, add cold water 280-390 part of≤40 ℃, slowly heat and urea is added, constantly be stirred to abundant dissolving, during temperature be controlled in 40 ℃;
Dissolved humic acid solution in the A reactor is added the B reactor;
After the dissolved humic acid solution has extracted in the A reactor, the humic acids of 20～40 parts of abundant dissolution precipitations of cold water at the bottom of still that preferably in the A reactor, adds≤25 ℃ again, and with dissolved humic acid solution adding B reactor, this process can repeat, and does not have precipitation at the bottom of still.
Slowly add phosphoric acid and constantly detect pH value, between the 5-7, promptly make fulvic acid complex liquid fertilizer of the present invention up to pH value.
Fulvic acid complex liquid fertilizer of the present invention has dissolved when using and has formed biuret, is easy to by plant absorbing after using, and absorption rate is fast, instant effect, and the cultivation mode that drips, sprays that is very suitable for present widespread use uses down.
