Description

A kind of low-cost high-efficiency fertilizer and preparation method thereof

Technical field

The present invention relates to bio-feritlizer technical field, be specifically related to a kind of low-cost high-efficiency fertilizer and preparation method thereof.

Background technology

In agricultural, utilize organic fertilizer, there are the various advantages such as the territory of saving from damage, protection of the environment, solution food problem.But it is not all right merely utilizing the production such as fecaluria, plant residue.Because the animal fecaluria, the plant residue etc. that do not become thoroughly decomposed have a large amount of unwanted bacterias, and fertilizer efficiency is very low, and growing way is slow, yield poorly, can cause disease and pest many, hinder plant-growth, make the harm such as soil deterioration.It is below some significant problems that use the product that do not become thoroughly decomposed to exist: 1) nitrogen hunger; Nitrogen hunger is to define by the ratio of carbon and nitrogen in compost composition (C/N ratio); Underdone compost is because the decomposition of nitrogen component is incomplete, likely causes occurring in soil nitrogen hunger.2) oxygen obstacle; If use the not complete compost becoming thoroughly decomposed, organism will ferment for the first time in soil, and fermenting process need to consume oxygen and the heating in soil, as the oxygen consuming is too much called the oxygen obstacle of soil; Oxygen obstacle and heating meeting bring very large strike to root and the soil ecosystem of crop.3) when nitric nitrogen uses non-decomposed compost, except retardation of growth, the content of nitric nitrogen also can be more than chemical fertilizer, and this point is also very clear and definite.Ropy organic fertilizer is harmful to.

At present, use the complete ripeness organic fertilizer of high-quality to overcome the above problems.But organic matter at least will could become thoroughly decomposed completely through the fermentation of two to three months in the situation that adding Fermentation Function microbial bacteria, want turning once and can produce stink at fermenting process per week, the heat that fermenting process produces can play the effect of killing bacterium and grass-seed, but the whole production process time is long, cost is high, affects organic grow cost.

Summary of the invention

For overcoming the defect of prior art, be of the present inventionly to provide the one can direct returning to farmland, shorten the low-cost high-efficiency fertilizer of compost Production Time.

Another object of the present invention is to provide a kind of preparation method of low-cost high-efficiency fertilizer, solve the problem that organic compost Production Time is long, cost is high, method is simple to operation.

The technical solution adopted in the present invention is as follows for achieving the above object:

A kind of low-cost high-efficiency fertilizer, it is to be that raw material is prepared from by fertilizer and bio-fermented liquid, wherein said fertilizer forms by be respectively animal excrement 50-80 part, organic 10-30 part, humic acid 5-15 part in weight part; The amount of wherein adding bio-fermented liquid in fertilizer per ton is 1-5 part.

In such scheme, described bio-fermented liquid be its be with cow dung and water be raw material, form at the effect bottom fermentation of bacterial classification stoste, wherein the consumption of cow dung is 1-5kg/1000L water, bacterial classification stoste addition is 1-2L/1000L water.Concrete preparation method is as follows for described bio-fermented liquid:

1) once stir: according to the above ratio cow dung is added in agitated pool, add water and stir after 6-8 minute, leave standstill 1-2 hour, filter;

2) secondary stirring: step 1) is filtered and taken out precipitation, stirs 6-8 again toward adding water in agitated pool, and standing 1-2 as a child, takes out precipitation;

3) fermentation: step 2) the liquid pump taken out after precipitation pumps in culture tank, adds water and bacterial classification stoste, cultivates 3-5 days.

In such scheme, described animal excrement are one or more mixing in chicken manure, cow dung, sheep excrement, pig manure.

In such scheme, described organic matter is one or more mixing in mushroom slag, the dregs of fat, lucky bar, plant ash.It is mainly the carbon-nitrogen ratio for adjusting fertilizer.

In such scheme, described humic acid is the former powder of humic acid.

A preparation method for low-cost high-efficiency fertilizer, it comprises the following steps:

1) be stacked to the fertilizer heap that is highly no more than 35cm after in proportion animal excrement, organic matter, humic acid being mixed;

2) biological decomposition liquid dilution 80-120 is evenly sprayed to Fei Duishang after doubly, makes the humidity of fertile heap remain on 50-70%.

A preparation method for low-cost high-efficiency fertilizer, it comprises the following steps:

1) Tumble Dry after in proportion animal excrement, organic matter and humic acid being mixed, obtain fertilizer;

2) fertilizer after oven dry is crossed 20 mesh sieves after pulverizing with pulverizer;

3) will after the dilution of biological decomposition liquid, be sprayed in the fertilizer after pulverizing and mix, the humidity of controlling fertilizer remains on 30-50%.

Compared to existing technology, beneficial effect of the present invention is:

1. the biological decomposition liquid adding in low-cost high-efficiency fertilizer of the present invention has digestion sterilizing function, can make the rapid deodorization and sterilization of compost;

2. the biological decomposition liquid adding in low-cost high-efficiency fertilizer of the present invention is that direct decomposition can not be generated heat in fertilizer, solving fertilizer can direct returning to farmland problem without compost maturity, be different from the fermentation of other products microorganism, the function of becoming thoroughly decomposed, greatly reduce fertilizer use cost and planting cost;

3. fertilizer provides nutrition to be divided into three phases to crop, in first stage fertilizer, containing having an appointment 30% labile protobitumen, can be decomposed nutrition to crop is provided by the original microbial activities of soil; Solid in soil containing the 60% difficult organic matter decomposing of having an appointment in subordinate phase fertilizer, in for a long time, slowly provide nutrition to crop by microbial activities; Phase III is the corrupt process of decomposing of the fiber of more difficult decomposition; Low-cost high-efficiency fertilizer of the present invention can be strengthened plant root growth, and can decompose rapidly the organic matter in soil completely, generates the nutrition of plant necessity, and the fertilizer efficiency that improves fertilizer makes it reach chemical fertilizer quick-acting, improves crop yield;

4. low-cost high-efficiency fertilizer of the present invention environmental protection, can will move ight soil and industrial waste changes into organic fertilizer, and play the effect that alleviates environmental pressure.

Below in conjunction with concrete embodiment, the present invention is described in further detail.
