Description
Technical field
The present invention relates to a kind of is the preparation method of the fertilizer of characteristic with the composting step, specifically, is a kind of working method of vegetable fertilizer.
Background technology
Along with the develop rapidly of modern agriculture science and technology, the usage quantity of chemical fertilizer is also increasing.Result according to relevant department's RR shows; After through the concentrated use chemical fertilizer in three to five years; The natural fertility of soil significantly descends along with annual continuous administration chemical substance, and the result of this decline causes annual for keeping high yield must strengthen the amount of application of chemical fertilizer gradually.Use chemical fertilizer for a long time in a large number and caused the expense increase on the one hand; Cause on the other hand that soil compaction, soil aggregate destroy, the preserve moisture and fertility permeability is poor, soil nutrient, pH value, mikrobe is seriously unbalance.The reason that causes this result is many-sided, but major cause is to lack to use the fertilizer that increases the natural soil fertility.Because contain each section that plant is easy to absorb in the fertilizer, element, mineral substance, organic matter and nutrition.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of working method of vegetable fertilizer, through the vegetable fertilizer of this working method preparation structure of improving the soil, strengthens soil fertility, improves the biological activity of soil organisms, the stimulating plant growth.
In order to address the above problem, the working method of vegetable fertilizer of the present invention, carry out as follows:
(1) by ratio of weight and the number of copies, get following raw materials for production ready: produce 15~25 parts of depleted bacterium bags behind the edible mushrooms, 15~25 parts of vegetable mould, 15~25 parts of cotton seeds, 8~12 parts of bancoul nuts, 8~12 parts of bone meal, cow dung just or 15~25 parts in sheep ight soil, 8~12 parts of plant ash;
(2) each raw material is once pulverized in kibbler respectively, made the raw material after the pulverizing can pass through 60~100 purpose screen clothes;
(3) by said ratio raw material stirring is mixed, put into the fermentation vat pile-fermentation, under 50~70 ℃ of conditions, nature 20~30 days;
(4) product behind the fermentation maturity is taken out oven dry, making the free water content of the finished product is 15~20%, carries out secondary after the oven dry and pulverizes, and makes the raw material after the pulverizing can pass through 80~150 purpose screen clothes, makes product.
Vegetable mould in the raw materials for production of the present invention is claimed leaf-humidified soil again, is the nutrition soil that plant leaf forms through microbiological degradation fermentation back in soil.Make in the process of plant leaf decomposition by multiple mikrobe alternating activity at this, formed the advantage that much is different from natural soils.The one, light weight is loose, and permeable venting capability is good, and the preserve moisture and fertility ability is strong; The 2nd, the porous crack, long-term application does not harden, and is prone to by plant absorbing.Use with other soil, can improve the soil, increase soil fertility; The 3rd, be rich in organic matter, humic acid and a small amount of VITAMINs, growth hormone, trace element etc., can promote growth and development of plant; The 4th, the high temperature in the decomposing and fermenting can kill germ, worm's ovum and weed seed etc. wherein, reduces disease worm, weeds harm.
Depleted bacterium bag also has a large amount of active bacterium behind the edible mushrooms in the raw materials for production of the present invention, but also contains humic class raw material such as cotton seed hull, and nutrition can be provided, and has reached the purpose of utilization of waste material again.
As the preferred embodiment of technique scheme, also comprise the oil cake of 8~12 weight parts in the said raw materials for production, with the fertility of further increase fertilizer.
As another preferred embodiment of technique scheme, also comprise the pine tag of 8~12 weight parts in the said raw materials for production, so that soil is more loose.
As another preferred embodiment of technique scheme, also comprise the charcoal of 8~12 weight parts and the peat of 8~12 weight parts in the said raw materials for production, to keep the fertility of soil.
Another preferred embodiment as technique scheme; In step (4); Also be provided with subsequent processing steps: add tobacco leaf water in the material after pulverizing, the free water content that makes the finished product is less than 20%, and the preparation method of tobacco leaf water is: tobacco leaf is added in the entry; At 90~100 ℃ of following lixiviate 10~20min, make after the filtration; The ratio of weight and number of tobacco leaf and water is 1: 1~2.Tobacco leaf water is in order to carrying out desinsection to soil, good disinsection effect, and the time length is of a specified duration.
As another preferred embodiment of technique scheme, tobacco leaf water also contains the plant disinfectant of 1~2% massfraction, the sterilant of 1~2% massfraction and the root-growing agent of 1~2% massfraction.With to disinfecting soil and biological proofing, and promote plant root growth.
The invention has the beneficial effects as follows:
(1) depleted bacterium bag contained a large amount of viable bacteria bodies as one of raw material in the fertilizer that after fermentation, makes after the present invention selected edible mushrooms for use, and these thalline can promote the conversion of nutrient in the soil, improve the validity of soil nutrient, improve the crop alimentary condition.
(2) increase soil fertility.Organic content height of the present invention and kind are abundant; These organic matters not only can produce inorganic nutrients such as a large amount of N, P, K in decay process; Can also produce multiple amino acids and multivitamin, these nutritive substances promote plant root growth, bring huge effect to growth and development of plant.
(3) improve soil.Organic matter forms coacervate in decay process, the density of fertilizer is littler than soil in addition, and the fertilizer that is manured into soil can reduce the unit weight of soil, improves the soil aeration situation, and soil property is improved.
(4) contain tobacco leaf water, sterilizing agent and sterilant in the fertilizer of the present invention, can improve detoxifying effect, purify edatope.
