Description
Technical field
The present invention relates to fertilizer preparing technical field, and in particular to a kind of special drip irrigation fertilizer of the eggplant kept soil from packing together and
Its preparation method.
Background technology
Drip irrigation fertilizer, is a kind of fertilizer applied with pouring, there is easy to use, crop easily to absorb due to drip irrigation fertilizer, fertilizer
The features such as effect is prominent, receives the welcome of vast farmerses；
Eggplant is the traditional vegetables of China, not only containing containing protein, fat, carbohydrate, vitamin and calcium,
The multiple nutritional components such as phosphorus, iron, the content of citrin is very high in eggplant, per 100 grams in i.e. contain 750 milligrams of citrin.Can increase
Adhesion between strong man's body cell, strengthens the elasticity of capillary, lowers fragility and permeability, prevents microvascular bleeding,
Various alkaloids such as trace element and choline, trigonelline, stachydrine, solanine such as eggplant is also phosphorous, calcium, potassium are especially purple
Vitamin content is higher in color eggplant, can suppress the increment of tumor in digestive tract cell, because eggplant has higher edible valency
It is worth and medical value, therefore how cultivates best in quality, nutritious healthy eggplant and has great importance, the cultivation of eggplant
Training wherein it is of paramount importance be fertilizer administration, growing way that it is directly connected to eggplant, the absorption to nutrient and to growth
The demand of environment, but traditional fertilizer in application often be merely able to ensure crop growth demand, it is impossible to solve by
The nutrient caused in fertilising utilizes imperfection, causes the problem of soil compaction, and it is dirty to solve heavy metal-polluted soil
The problem of dye, it can be seen that how developing one kind can either improve nutrient utilization rate, can effectively solve the problem that soil again
Earth is hardened, the fertilizer of heavy metal pollution of soil problem is modern agricultural development in the urgent need to for this purpose, the present inventor is by a large amount of
Experiment and research provide special drip irrigation fertilizer of a kind of eggplant kept soil from packing together and preparation method thereof.
The content of the invention
To solve above-mentioned technical problem, the invention provides a kind of special drip irrigation fertilizer of eggplant kept soil from packing together and its system
Preparation Method.
The present invention is achieved by the following technical programs：
A kind of special drip irrigation fertilizer of the eggplant kept soil from packing together, it is made up of following raw material：Urea 45-65 parts,
It is ammonium nitrate 11-17 parts, potassium dihydrogen phosphate 13-19 parts, sulfate 10-20 parts, reaction promoter 15-21 parts, auxiliary material 9-15 parts, additional
Agent 6-10 parts.
The special drip irrigation fertilizer of the eggplant kept soil from packing together is made up of following raw material：Urea 50-60 parts, nitric acid

7-9 parts.
The special drip irrigation fertilizer of the eggplant kept soil from packing together is made up of following raw material：55 parts of urea, ammonium nitrate
14 parts, 16 parts of potassium dihydrogen phosphate, 15 parts of sulfate, 18 parts of reaction promoter, 12 parts of auxiliary material, 8 parts of additive.
It is 1 according to mass ratio that the sulfate is potassium sulfate, magnesium sulfate:1 proportions are formed.
The reaction promoter is potassium thiosulfate.
The auxiliary material is the one kind in ammonium sulfate, boric acid, ferrous sulfate.
The additive is amino acid, humic acid, yellow humic acid, alginic acid, plant growth regulator, the one of herbicide kind
Plant or several；
The plant growth regulator is at least one in brassinosteroid, triacontanol, indolebutyric acid；
The herbicide is the one kind in Acetochlor, napropamide, Oxyfluorfen.
Present invention also offers the preparation method of the special drip irrigation fertilizer of the above-mentioned eggplant kept soil from packing together, the method include with
Lower step：
A, raw material are crushed：Respectively urea, ammonium nitrate, potassium dihydrogen phosphate, sulfate, auxiliary material are crushed into 50-60 mesh；
B, raw material mixing：Urea, ammonium nitrate, potassium dihydrogen phosphate, sulfate, the auxiliary material that crushing is completed is in order successively
It is added in the mixing channel containing water and mixes；
C, stirring：Steam is passed through in mixed process for 60-80m/s according to flow velocity to be stirred, add additive thorough
Bottom stirs, and after liquid cooling to be mixed slip is obtained；

With reference to specific experiment example, the present invention is described further：
Experimental example 1
This drip irrigation fertilizer field demonstration test, experimental field ground is in Guizhou, has a moderate climate, with heavy rainfall, using every mu of field
Label is tested, and 10 mu of fields, the drip irrigation fertilizer prepared using conventional fertilizer application and conventional fertilizer application+the present embodiment 1-9 are selected altogether
Eggplant cultivation experiments are carried out, experimental result is as shown in table 1：
The drip irrigation fertilizer field demonstration test of table 1
| Project | Theoretical per mu yield (kilogram) | Actual per mu yield (kilogram) |
| Conventional fertilizer application | 14000-15000 | 14756 |
| Conventional fertilizer application+embodiment one | 14600-15500 | 15801 |
| Conventional fertilizer application+embodiment two | 14600-15500 | 15763 |
| Conventional fertilizer application+embodiment three | 14600-15500 | 15689 |
| Conventional fertilizer application+example IV | 14600-15500 | 15899 |
| Conventional fertilizer application+embodiment five | 14600-15500 | 15879 |
| Conventional fertilizer application+embodiment six | 14600-15500 | 15903 |
| Conventional fertilizer application+embodiment seven | 14600-15500 | 15931 |
| Conventional fertilizer application+embodiment eight | 14600-15500 | 15921 |
| Conventional fertilizer application+embodiment nine | 14600-15500 | 15898 |
The plantation of eggplant its yield is carried out by the way of conventional fertilizer application as seen from the above in theoretical value, and adopts normal
The rule drip irrigation fertilizers prepared of fertilising+the present embodiment 1-9 carry out the plantation of eggplant its yield and are not only above theoretical value but also much
It is using conventional fertilizer application higher than independent, therefore the plantation for carrying out eggplant using the present invention is that have higher effect of increasing production.
Experimental example 2
Heavy metal-polluted soil process experiment：
Surveyed as carrier addition exogenous heavy metal pollutant with the free of contamination cinnamon soil in Guizhou Province and contained at its soil depth 5-20cm
Pb100mg/kg, Cd6mg/kg, Cr900mg/kg, Cu980mg/kg, using the soil as experiment soil, by the embodiment of the present invention
In the drip irrigation fertilizer prepared throw in experiment soil, heavy metal concentration inspection at soil soil depth 5-20cm is carried out after 15 days
Survey, its testing result is as shown in table 2：
The heavy metal-polluted soil of table 2 processes experimental result
From the foregoing, it will be observed that being thrown in experiment soil after 15 days using the drip irrigation fertilizer prepared in the embodiment of the present invention, soil
Content of beary metal at 5-15cm is significantly reduced, and illustrates that the thio sulfide contained in this drip irrigation fertilizer occurs with heavy metal ion
Reaction production precipitation, so as to heavy metal ion be fixed, prevents it from passing through leaching and footpath stream migration, in addition in this drip irrigation fertilizer
Thio sulfide valence heavy metal ions can also be reduced into lower valency, effectively reduce its toxicity and dissolubility.
