Description
Technical field
The invention belongs to technical field of fertilizers more particularly to a kind of leafy vegetable special organic nutrient solution for cultivating fertilizer and its preparation sides
Method.
Background technique
Fertilizer is to provide the necessary nutrient of one or more kinds of plant growths, improves soil property, improves soil
One substance of fertility level, is one of material base of agricultural production.Solid fertilizer and liquid can be divided by fertilizer physical state
Body fertilizer, with the development of green agriculture and the ecological agriculture, conventional solid fertilizer is since its utilization rate is not high, be easy to cause soil
Earth is hardened, is not easy to be absorbed by plants, bring a series of environmental problems etc. gradually to be replaced by liquid fertilizer.
Liquid fertilizer and abbreviation liquid fertilizer are the new-type fertilizers of highly enriched, the high fertilizer efficiency of one kind, multi-functional, full nutrition Synergistic type.
Relative to solid fertilizer, liquid fertilizer has the advantage that and 1) can be absorbed by plants in very short time, avoids being lost, utilization rate
It greatly improves；2) it can be uniformly distributed in soil after applying, not will cause soil hardening or the non-uniform problem of plant absorption；
3) it can be administered by the way of sprinkling irrigation, trickle irrigation or pouring, it is convenient and efficient, it is time saving and energy saving；4) will not exist as solid fertilizer
Isolation is generated in storage and transport process and causes fertilizer quality irregular；5) the problem of moisture absorption and agglomeration is not present in product；It 6) can be with
It is mixed with fungicide, Insecticides (tech) & Herbicides (tech) etc. and can be uniformly mixed；7) in fertilizer process and after administration not
It is also easy to produce environmental pollution.Therefore, liquid fertilizer is more advantageous to the production of crops high quality.
There are many type of vegetables, and wherein leafy vegetable is edible for people with tender blade, petiole or stem.They
Nutrition general character is: nutrient requirement rate is big.Since this kind of vegetables edible portion ratio is big, the nutrient of soil is returned to relatively
Few, annual multiple crop index is high, and growth is rapid, and planting density is very big, therefore the requirement to fertilizer and water condition is very high, especially
Requirement to elements such as N P and K calcium boron molybdenums is very high, for example, when nitrogen (especially nitrate nitrogen) abundance when, the tender succulence of blade and
Few fiber；When nitrogen deficiency, then plant is short and small and fiber is more, and leaf area is small, and color is yellow and coarse, loses edible value, therefore
A kind of special organic nutrient solution for cultivating fertilizer is provided for it in leafy vegetable growth course, to the raising of its yield and quality to Guan Chong
It wants.
Summary of the invention

Preparation method based on the leafy vegetable special organic nutrient solution for cultivating fertilizer that above technical scheme provides, first to by agriculture
The raw material of field waste, rubbish from cooking and Stock raising waste composition carries out anaerobic fermentation processing, in the ferment filtrate of acquisition
Organic battalion such as organic nutrient substance and microelement, such as humic acid, fulvic acid, amino acid, water-solubility protein rich in
Feeding substance can directly be absorbed by the blade face of leafy vegetable, supplemented plant nutrient, improved the yield and quality of vegetables.And it is sending out
The harmful substances such as pathogen present in raw material, pest ovum can be killed during ferment, so that the organic fertilizer peace being prepared
It is complete reliable.In addition, still a large amount of and micro- containing macromolecular organic nutrient substance more abundant, part in the filter residue that fermentation generates
The corpse of secondary element and the multiple-microorganism generated during the fermentation or the multiple-microorganism of kill, after fermentation
Filter residue passes through ozone oxidation, by indissoluble therein or undecomposed macromolecular organic nutrient substance can be degraded into small
Molecular substance, part is a large amount of and microelement further dissolves out, while can also be killed and be filtered by the oxidation of ozone
Microorganism in slag, and make the cell degradation of microorganism, so that existing various nutrients in microbial cell are released,
Such as the various nutrient elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, boron, zinc, molybdenum, copper, manganese, iron.The present inventors have additionally discovered that this stage
More there is (this may be the result that ozone decomposes microbial cell) in the form of organic nitrogen in the nitrogen being present in oxidation slurries,
Rather than by leafy vegetable with greater need for nitrate nitrogen and ammonia nitrogen in the form of exist, therefore the present inventor also continues after oxidation
Raw material is continuously added in slurries, then successively carries out spontaneous fermentation and anaerobic fermentation and the ozone Oxidation Treatment of longer time step
Suddenly, the nitrogen in finally obtained oxidation filtrate exists mostly in the form of nitrate nitrogen and ammonia nitrogen, and at the same time further improving
The content of other nutrients such as phosphorus, potassium, calcium, magnesium, sulphur, boron, zinc, molybdenum, copper, manganese, iron etc., so that the leaf class vegetable being prepared
The dedicated organic fertilizer of dish is full of nutrition, is more conducive to the growth of leafy vegetable.The present invention is also based on the peptizaiton of dispersing agent
With bentonitic suspension effect, the two, which cooperates, enables various nutrients in the liquid fertilizer provided to be stabilized, without
Sedimentation or other side reactions can occur, ensure that the stability of liquid fertilizer provided by the invention.
The dedicated organic fertilizer of leafy vegetable provided by the invention is discarded using farmland waste, rubbish from cooking and aquaculture
Object is raw material, not only at low cost, additionally it is possible to the discharge for reducing waste is conducive to the effective use for protecting environment and resource, and
And the nutritive element contents such as organic in the organic fertilizer being prepared and inorganic nutrients are abundant comprehensively, N P and K are enriched, are not contained
Any biological bacteria, therefore ecological safety is reliable, is easier to be absorbed by plants, it will not when by way of foliage-spray for vegetables
Pest and disease damage, and the growth and quality for having the effect of significantly improving the yield of leafy vegetable, effectively facilitating vegetables occurs, has
Ecology, society and economic triple benefits.
Specific embodiment
