Abstract
The present invention discloses an organic potash fertilizer containing urea. Urea is added in organic potash fertilizer with the patent number 96118644.5, and the weight ratio is as follows: organic potash fertilizer: urea = 100: 1 to 37.5. The prepared organic potash fertilizer contains organic acid and inorganic nutrition of potassium and nitrogen, wherein the urea content can reach 27.3%, and nitrogen nutrition is increased by 12.56%. Therefore, the present invention is a novel liquid organic compound fertilizer, and is more suitable for the requirements of crop nutrition.
Description
Technical field
The invention belongs to the production and the preparing technical field of fertilizer, relate to a kind of organic (acid) potash fertilizer that contains urea.
Background technology
Organic (acid) potash fertilizer that present applicant produces is a kind of foliage fertilizer, and it is the patent (patent No.: ZL96118644.5) produce, become commodity according to the applicant.Product since putting on market in 1996, with its have the fertilizer efficiency height, easily absorb, consumption is few, expense is low, amount of increase in production is obvious, and characteristics such as nontoxic, harmless, noresidue have become the fertilizer brand of production " green food ", are subjected to the welcome of vast farmers deeply.
Foliage fertilizer is that a kind of novel fertilizer, particularly crop of development in recent years topdresses effect than use potash fertilizer is better separately.Organic acid is not only the acceptor of nitrogen assimilation, also can regulate the physiological function of crop, and potassium can promote photosynthesis, and both are in conjunction with better effects if.As foliage fertilizer, the organic potassic fertilizer of patent No. ZL96118644.5 contains the organic acid potassium salt with following structural:
In the formula: R is CH
3-, CH
3CH
2-, CH
3COCH
2CH
2-, CH
3CHNCH
2-, HOOCCH
2CH
2-, K is a potassium.
Above-mentioned organic potassic fertilizer blemish in an otherwise perfect thing be not contain the nitrogen element in organic (acid) potash fertilizer, if urea can be added in above-mentioned organic (acid) potash fertilizer, the better effect of performance organic acid assimilation nitrogen makes nitrogen, potassium and organic acid performance synergistic effect in the fertilizer, and its effect can be more remarkable.Do not find at present the relevant report of this respect as yet.
Summary of the invention
The objective of the invention is to, a kind of organic potassic fertilizer that contains urea is provided, this organic potassic fertilizer that makes not only contains organic acid, also contains potassium, nitrogen inorganic nutrients, is a kind of new liquid mixed organic manure kind.
In order to realize above-mentioned task, technical scheme of the present invention is:
Form by following weight ratio by organic potassic fertilizer and urea: organic potassic fertilizer: urea=100: (1～37.5), described organic potassic fertilizer contains the organic acid potassium salt with following structural:
In the formula: R is CH
3-, CH
3CH
2-, CH
3COCH
2CH
2-, CH
3CHNCH
2-, HOOCCH
2CH
2-, K is a potassium.
The above-mentioned concrete preparation method of organic potassic fertilizer who contains urea is, normal temperature in described organic liquid potash fertilizer (20 ℃) adds urea down, its weight ratio is: organic potassic fertilizer: urea=100: (1～37.5), then stir, urea fully is dissolved in the organic potassic fertilizer.
Theoretical basis of the present invention:
The solubleness of urea in 20 ℃ of following water of normal temperature is 105g/100g, and solubleness has reached 37.5g/100g in the commodity organic potassic fertilizer, and has contained 60% solute in the commodity organic potassic fertilizer.Obviously, this is a kind of very significant discovery.Through experimental results show that of applicant, urea solvability in the liquid organic potassic fertilizer is very good, organic acid and nitrogen are under the coordination of potassium element, assimilation is more remarkable, make the using value of fertilizer higher, the present invention will add certain amount of urea in organic (acid) potash fertilizer, makes it become organic (acid) potash fertilizer that adds urea.Not only containing organic acid in the fertilizer that makes, also contain potassium, nitrogen inorganic nutrients, is a kind of new liquid mixed organic manure kind.
And urea is best a kind of of nitrogenous fertilizer as foliage fertilizer, very easily absorbed by crop.Urea water-soluble fabulous, in applicant's liquid organic potassic fertilizer, add the urea of 1-37.5%, when the weight of adding when urea and the ratio of liquid organic potassic fertilizer reach 37.5%, urea content can reach 27.3% in the liquid mixed organic manure that obtains after the interpolation, nitrogen nutrition content increases 0.46%-12.55%, and potassium oxide content reduces to 17.82-13.09% by 18.0%; Relative the increasing of total amount in view of nutritive ingredient in the product (nitrogen and potassium oxide) is more suitable for the needs of crop to multiple nutrients.
Embodiment
Organic (acid) potash fertilizer that contains urea of the present invention has two kinds of approach when preparing product; A kind of approach is to keep the commodity brand of the organic potassic fertilizer that makes with patent No. ZL96118644.5 constant, promptly in the liquid organic potassic fertilizer production process of the existing above-mentioned commodity of company, product is analyzed, as the K of product
2During O%=18.5-20.0, add the industrial urea (the concrete operations index sees attached list 1) of 1.0-10%, nitrogen nutrition increases 0.46-4.18% in the product; Then stir (produce the urea solubility property winter and descend, can be heated to 40-60 ℃), whole dissolvings of urea and even back product.

As can be seen from the above table, add urea content less than 1%, K
2O% variation and nitrogen nutrition increase are all very little, and no practical significance adds the product that urea obtains under this approach, and the total mass of organic potassic fertilizer is constant, and nitrogen nutrition increases, and keeps the commodity brand of the existing organic potassic fertilizer of company.
Second kind of approach is to have added on the 1-10% urea basis at first kind of approach, continue to add urea, the weight of urea is reached in 37.5%, the product nitrogen content that obtains is risen significantly, urea content reaches 27.3%, the nitrogen nutrition content of fertilizer is increased to 12.55% from 4.18%, and potassium oxide content descends by a small margin; And total nutrient content raises, and the applicant separately as a kind of product, declares new commodity brand with the product of second kind of approach preparation.Following table provides some real example:
| K 2O％ | Add urea (%) | Add back K 2O％ | Nitrogen nutrition increases (%) |
| 18 | 15 | 15.65 | 6.00 |
| 18 | 20 | 15.00 | 7.67 |

| 18 | 30 | 13.85 | 10.62 |
| 18 | 37.5 | 13.09 | 12.55 |
Organic (acid) potash fertilizer land for growing field crops application effect that contains urea:
The applicant is at experiment base plantation wheat, the organic potassic fertilizer and the clear water thereof that adopt original commodity organic potassic fertilizer (patent No. ZL96118644.5) and contain urea have carried out simultaneous test, experiment showed, that the more original organic potassic fertilizer of organic potassic fertilizer that contains urea of the present invention has better effect of increasing production.Test and variance analysis data are as follows:
Different fertilizer is to the influence of wheat yield
