Abstract
The invention provides an amino-acid water-soluble fertilizer special for cotton and a preparation method thereof.The amino-acid water-soluble fertilizer is dark brown liquid and can be applied in a sprayed or flushed mode and has the advantages that an amino acid and trace elements can perform adequate chelating reaction through a chelating agent, the waste caused by the fact that the trace elements are in a free state and are easily subjected to leaching loss of a traditional compounding method is overcome, and the utilization rate of the trace elements in the fertilizer is improved; a 'three-step heating + standing reaction method' is adopted in the production process of the fertilizer, energy consumption is reduced, and the production cost is greatly reduced; precipitates produced in the production process of the fertilizer are filtered out by adopting a centrifugal filtration method, and the laying and precipitation phenomena produced due to too long storage time of the product are avoided; an experimental verification shows that the amino-acid water-soluble fertilizer can make cotton leaves dark green, large and thick and make plants healthy and strong, the cotton boll numbers of a single plant and the weight of a single boll are increased, the resistance during a whole growth period is enhanced, the average increase rate is 12% or above, and planting benefits are considerable.
Description
Technical field
The present invention relates to seed amino acid water-soluble fertilizer and preparation method thereof, especially one grow cotton special ammonia base acid water-soluble fertilizer and preparation method thereof, belong to technical field of fertilizer production.
Background technology
Cotton Gossypii, is the kind seed hair fiber of Malvaceae (Malvaceae) Gossypium (Gossypium) plant, originates in subtropical zone, is one of topmost crops in the world.The major-minor product of Cotton Gossypii has higher value, as " Cotton Gossypii whole body is all precious " described in forefathers, it is most important fibre crops, is again important oil crop, also it is the cereal crops containing high protein, or weaving, fine chemical material and important strategic materials.The growth promoter of Cotton Gossypii, it is necessary to a certain amount of N P and K and other nutrient.Quantity and the ratio of the different nutrient elements needed for yield level are different.To a certain extent, along with the increase of fertilizers input amount, the yield of Cotton Gossypii also improves accordingly, but the increase of yield is not in direct ratio with fertilizer requirement increase.Cotton Gossypii need nutrient a lot, it is known that just have kind more than ten, mainly have nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, ferrum, zinc, manganese, copper, molybdenum, boron, chlorine.
Plant growing particularly photosynthesis is had the facilitation of uniqueness by aminoacid, and it can increase chlorophyll content of plant, improves the activity of enzyme, promotes the infiltration of carbon dioxide, makes photosynthesis more vigorous, and to improving, crop quality is significant.Amino acid fertilizer is executed in plant-spraying or punching can increase various nutrients required in plant, aggravate the accumulation of dry and from plant root or leaf portion to the running speed at other positions and quantity, regulate ratio and the poised state of a great number of elements, trace element and various nutrition, thus playing the effect regulating plant normal growth.Aminoacid may also operate as the effect of chelating agent.N, P, the a great number of elements such as K, Zn, Fe, Cu, Mn, B, the trace element such as Mo are necessary materials in crop body, can often there is lacking the symptom of some element in crop, its reason be can be absorbed by crops live part content very little, and aminoacid can with slightly solubility element generation chelatropic reaction, element needed for crop is produced protective effect, and it is good to generate dissolubility, chelate easily absorbed by crops, thus being conducive to plant absorption, each amino acid water-soluble fertilizer is of a great variety on the market at present, but the dedicated fertilizer for Cotton Gossypii is less, the present invention is just specific to the one special amino molten fertilizer of sour water of Cotton Gossypii uptake characters exploitation.

6, test method
The method of contrast is taked in this demonstration test, if two process, does not set repetition, wherein demonstration area 5 mu, compares area 5 mu；
Process 1: conventional fertilizer application+spray the Cotton Gossypii special amino molten fertilizer of sour water
Process 2(CK): conventional fertilizer application+spray clear water
When conventional fertilizer application is whole ground, high-quality well-rotted farmyard manure 1000 kilograms executed by base, adds 40 kilograms and 20 kilograms carbon ammoniums of calcium superphosphate and 50 kilograms of phosphate fertilizer.Cotton Gossypii was in nursery on April 18 in 2012, and May 12 transplanted.Processing 1 on the basis of conventional fertilizer application, respectively at seedling stage, squaring period, initial bloom stage and the foliage-spray Cotton Gossypii special amino molten fertilizer of sour water after pinching, seedling stage is with 2000 times of liquid foliage-sprays；Squaring period is with 1500 times of liquid foliage-sprays；Initial bloom stage is with 1000 times of liquid foliage-sprays；Bind with 500 times of liquid foliar sprays after pinching.
7, interpretation of result
7.1, the impact on biology and economic characters
After spraying aminoacid water-soluble fertilizer, Cotton Gossypii single-strain bell-forming number, Single boll weight being added up, statistical result is in Table 2.
Table 2 Cotton Gossypii biological character statistical table
| Process | Density (plant/acre) | Single-strain bell-forming number (individual/strain) | Single boll weight (g) |
| Process 1 | 1200 | 15.8 | 5.3 |
| Process 2(CK) | 1200 | 13.9 | 4.8 |
(note: data above is 3 40m of two process2Average)
Field observation is analyzed, spray the dark green plumpness of demonstration area blade of this fertilizer, robust plant, single-strain bell-forming number and Single boll weight increase, whole period of duration resistance strengthens, diseases and insect pests resistance is strong, and along with the increase effect spraying number of times becomes clear day by day, thus may infer that this fertilizer is to promoting that Developmental of Cotton has positive effect.
7.2 yield and performance analysis
Produced by actual meter, spray the demonstration area yield of this fertilizer apparently higher than matched group (CK).
Table 3 output of cotton and input-output ratio synopsis
(calculating by local unginned cotton market price 8 yuan/kilogram).
8, interpretation of result
Aminoacid water-soluble fertilizer of the present invention, dosage form (water preparation), technical specification (aminoacid >=100g/L；Cu+Fe+Mn+Zn+B+Mo >=20g/L) obvious effect of increasing production on Cotton Gossypii, spray the plot of aminoacid water-soluble fertilizer than comparison (CK) plot volume increase 9.3kg/ mu, rate of growth is 12.0%, and input-output ratio is 1:13.9, obvious effect of increasing production.
Above example is merely to illustrate technical scheme, but not is limited；Although being described in detail by invention with reference to previous embodiment, but for the person of ordinary skill of the art, still the technical scheme described in previous embodiment can be modified, or wherein portion of techniques feature is carried out equivalent replacement；And to these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of present invention technical scheme required for protection.
