Description
Technical field
The present invention relates to technical field of fertilizers, and in particular to a kind of nitrate-based compound fertilizer suitable for planting fruit trees.
Background technology
It is normal raw to maintain it, it is necessary to absorb appropriate various mineral nutrient elements from soil during fruit tree growth
Long development, wherein, including a great number of elements such as nitrogen, phosphorus, potassium, moderate-element such as calcium, magnesium, sulphur, trace element as iron, manganese, copper, zinc,
Boron etc., especially fruit tree are in early spring germination, florescence and the phase of bearing fruit, the hair using the complete quick-acting fertilizer of N P and K to fruit tree
The quality and yield for educating degree and fruit have a significant impact.
Nitrate-based compound fertilizer typically contains more nitrate nitrogen and a certain amount of ammonium nitrogen, and required for plant growth
Other nutrients such as phosphorus potassium, compared with conventional composite fertilizer, there is the characteristics of quick dissolved, quick effect, because conventional fertilizers are in nitrogen
Converting in link, nitrogen can be volatilized and be lost in the form of ammonia, and nitrogen nutrient wastes at least more than 50%, and in nitrate-based compound fertilizer
Nitrate nitrogen can directly be absorbed by crop, thus utilization rate of fertilizer greatly improves, and belongs to high-quality and efficient, green, nuisanceless
New-type fertilizer.
At present, the nitrogenous fertilizer market in China is more based on urea, and the ratio shared by nitrate-based compound fertilizer is extremely low, domestic nitre sulfenyl
Composite heat transfer enterprise is less, and China is every year from external import nitrate-based compound fertilizer to meet domestic market demand, therefore, nitre sulphur
Base composite fertilizer has huge market potential.Although nitrate-based compound fertilizer has the advantages of fertilizer efficiency is fast, nitre sulfenyl is compound simultaneously
Fertilizer easy moisture absorption caking under the conditions of long-term storage, has the following disadvantages after long-term use of：One is generally existing soil is easy to plate
Knot；The second is soil permeability reduces, in the case of defective aeration, nitrate anion can form N through denitrification2O and
N2, so as to cause the loss of nitrogen；The third is nitrate-based compound fertilizer storage for a long time is easily hardened blocking and influences its commodity value, one
As commonly use talcum powder and wrapped up with fertilizer multiple, though alleviating the agglomeration problems of product to a certain extent, add product
In dust content.

The aperture of vibratory sieve is 2.0mm*4.8mm；
Second of cooling refers to that the granulate mixture after second of microwave drying is naturally cooled into temperature is less than
25℃。
The present invention comprises at least following beneficial effect：
(1) anticaking agent effectively prevents caking of the nitrate-based compound fertilizer in storage between fertiliser granulates surface, wherein
Activation tricalcium phosphate replaces conventional talcum powder to invest fertiliser granulates surface, possesses the high wet ability of appearance, weakens caused by humidity
Caking occurs, while cationic surfactant forms uniform hydrophobic membrane in fertiliser granulates surface, is reducing its caking capacity
Meanwhile the sustained release performance of fertiliser granulates has been properly increased, improve the utilization rate of fertilizer；
(2) microwave drying is low compared to conventional heated-air drying temperature, and for granular mixture, heated-air drying is easily made
It is chapped from the cold into particle surface, moisture distribution of the particle from inside to surface is uneven, and the microwave drying time is short, and can evenly drying
Grain, dries thorough, can keep away fertilizer and exempts to stack its internal moisture for a long time and migrates to surface and caking phenomenon occurs；
(3) compound sodium nitrophenolate is broad spectrum type plant growth regulator, and fruit tree vine growth and development can be accelerated by being formulated in fertilizer,
Promoting root growth strong sprout, flower and fruit protecting are played, is beared fruit and is expanded, improves yield and enhancing anti-adversity ability and other effects；
Sodium humate can play the effect of disease resistance increasing both production and income to fruit tree, such as to treatment apple tree, pear tree and peach
The rot of the fruit trees such as tree has the effect of fine, while certain synergism is played in the improvement to soil texture；
Urine base chelating ion calcium can promote the absorption of fruit tree nutrient and the formation of chlorophyll, increase pericarp toughness, promote fruit
Real uniform coloring, extend storage phase and shelf life, improve crop quality, the effect of crop yield is improved, to fruit tree because calcium deficiency is drawn
The early ageing that rises, plant is short and small, the tip of a root is rotten, yellows, malformed fruit, outer skin phenomenon etc. have superpower prophylactic-therapeutic effect；
(4) soil granular structure be electronegative soil clay particle with organic matter by the polyvalent cation of positively charged couple and
Into phosphate fertilizer is excessive, then causes phosphate anion to combine to form insoluble phosphate with the calcium and magnesium cation in soil, destroys soil
Crumb structure causes soil hardening, and when potash fertilizer is excessive in fertilizer, it can will form the polyvalent cation displacement of soil granular structure
Out, the crumb structure of soil is equally destroyed, JT composite bacteria pulvis contains multiple-microorganism flora, and its secretion can dissolve soil
Phosphate in earth is by phosphorus element, potassium and micro- cation release, the recovery crumb structure in the form of key bridge, elimination soil plate
Knot；
(5) temperature after cooling down for the first time is too high, can influence compound sodium nitrophenolate component and adhere to particle surface, cause compound nitrophenol
Sodium scatters and disappears；Temperature is too low, is unfavorable for the follow-up coating for carrying out granulate mixture, meanwhile, because needing to carry out second of microwave, suitably
Cooling can save energy expenditure.
