Description
Technical field
The present invention relates to a kind of composition, in particular to a kind of long-acting water-soluble fertilizer and preparation method thereof.
Background technology
Water-soluble fertilizer is due to saving the advantages that artificial, quick, and recent years is developed rapidly in China, Ye Shiwo
Development trend in state's modern agriculture chemical fertilizer.Fertilizer is used together by water-soluble fertilizer with water, solves the difficulty that fertilising must go to the field
Topic, greatly improves efficiency.It is short yet with water-soluble fertilizer fertilizer efficiency period, cause using frequent, common water-soluble fertilizer 7~10
It is applied once, every time about 3~7kg/ mus, and in the so short time, crop uptake is limited, but makes nitrogen, phosphorus, potassium nutrition big
Amount accumulation in soil, the problems such as causing secondary salinization, soil hardening, soil acidification getting worse, or even some places go out
Existing small Lao Miao, malformed fruit, dead canopy, phenomena such as disease is more, the nitrate largely accumulated in soil cause the quality of veterinary antibiotics
Decline, and carried out risk for human body health care belt.Water-soluble fertilizer utilization rate is improved, extends the term of validity of nutrient, improves the same of yield
When ensure food security be the task of top priority.
The content of the invention
It is an object of the invention to provide a kind of long-acting water-soluble fertilizer, the long-acting water-soluble fertilizer can improve water-soluble fertilizer nitrogen phosphorus
The utilization rate of potassium nutrition, extend nutrient in effective RT of soil, be made for thing and absorb；Accumulation in activating soil
Phosphorus, potassium nutrition, nitrate content is reduced, reduce disease incidence, using simple, beneficial to popularization.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of long-acting water-soluble fertilizer, it is made up by weight ratio of the following raw material：Water-soluble 100 ~ 800 parts of nitrogenous fertilizer, water solubility
100~1000 parts of phosphate fertilizer, 100~800 parts of water soluble potassic fertilizer, 20~100 parts of biochemical fulvic acid potassium, 3,4 dimethyl pyrazole phosphoric acid
0.1~3 part of salt, 0.1~5 part of chitosan oligosaccharide, 4- amino -0.1~3 part of 1,2,4-triazoles, the water-soluble nitrogenous fertilizer are urea, nitric acid
One kind or any several combinations in ammonium, ammonium sulfate, MAP, Diammonium phosphate (DAP), APP, the water soluble phosphorous fertilizer is phosphorus
A sour ammonium, Diammonium phosphate (DAP), APP, potassium dihydrogen phosphate, one kind in dipotassium hydrogen phosphate or any several combinations, it is described water-soluble
Property potash fertilizer be potassium dihydrogen phosphate, dipotassium hydrogen phosphate, potassium nitrate, one kind in potassium sulfate or any several combinations.
Such scheme can do following optimization, 306 parts of potassium nitrate, 175 parts of potassium dihydrogen phosphate, 182 parts of MAP, urine
300 parts of element, 35 parts of biochemical fulvic acid potassium, 1 part of 3,4 dimethyl pyrazole phosphate, 0.5 part of chitosan oligosaccharide, 4- amino -1,2,4-triazoles
0.5 part.
When prepared by above-mentioned long-acting water-soluble fertilizer, the biochemical fulvic acid potassium of the weight is heated to 50 DEG C first；Then will
The 3 of the weight, 4 dimethyl pyrazole phosphate, chitosan oligosaccharide and 4- amino -1,2,4-triazoles are well mixed, and are added to biochemical Huang
In rotten sour potassium, stir and be incubated 30 minutes at 50 DEG C, be then down to room temperature and be transferred in stirred tank；Most backward stirred tank
Interior water-soluble nitrogenous fertilizer, water soluble phosphorous fertilizer and the water soluble potassic fertilizer for adding the weight, stirs and obtains long-acting water-soluble fertilizer.
, it is necessary to be carried out under the conditions of dehumidifying in above-mentioned preparation process.
The fertilizer efficiency phase of the present invention is obviously prolonged, and meets crop growth needs very well, is advantageous to activating soil and presses down
The generation of harmful fungoid, bacterium in soil processed, promote plant strain growth, improve resistance, so as to reach long fertilizer efficiency, high usage,
Reduce the purpose of soil nitrate level.In preparation process, by 3,4 dimethyl pyrazole phosphate, chitosan oligosaccharide and 4- amino -1,
It is added to after the mixing of 2,4 triazoles in the biochemical fulvic acid potassium for being heated to 50 DEG C, constant temperature stirring a period of time contributes to biochemical yellow rotten
Sour potassium fully adsorbs 3,4 dimethyl pyrazole phosphate, chitosan oligosaccharide and 4- amino -1,2,4-triazoles, reduces three in process of production
Loss and moisture absorption, improve composition entirety using effect.
