How many days does the fermentation process of high quality organic fertilizer compost generally tak

The process of stacking high-quality organic fertilizer for fermentation is very complex, and you can choose to look at it from two aspects. The first fermentation must extract the minerals in it and use them as conditions for irrigating the crops. During fermentation, you can smell a foul smell, and at this time, you can see that the color of the organic fertilizer has changed to a certain extent.

Farmers will gradually peel off the organic fertilizer and extract some of the whitish things inside. Second, organic matter is constantly humified, decomposed and then produced as carbon dioxide. With nutrients, organic fertilizer can be fully utilized.

Farmers will make good use of all the conditions, so that the fertilizer can ferment faster. <>

During the fermentation process, it is necessary to ensure the effect of aeration, otherwise it will not be possible to carry out a successful fermentation. If the weather is hot, the decomposition will be faster, and more heat will be generated. In winter, when the weather is cold, it is best to cover it with a film to help it ferment.

When it's cold, there's no way for the matter to clump together, and there's not even steam to regulate it inside. There may be some bad organic acids in the middle, and there is no way to reduce the substance. After using the film, it will maintain a stable temperature just like the germination of a seed.

After a long time, fermented organic fertilizer can be produced, which can be used as fertilizer for crops. <>

If organic fertilizer is not corroded, it is likely to have a certain impact on crops. The first will hinder the germination process of the seed and allow it to continue to grow insects. Not only will it bite off the roots, but it may even cause the crops to die.

Second, if the crop does not achieve the effect of decay, the soil will not be permeable. If you can't absorb some organic matter, you can't get more nutrients in the soil. <>

In general, there is a lot of organic fertilizer and farmhouse fertilizer in the countryside, and the two can be properly combined. After fermentation, it can be put to good use whether it is placed in the field or in the vegetable field. It can provide certain nutrients to crops and rice, and even retain a certain amount of moisture in the soil.

About 60 days, if you want to use it better, you must ferment for two months, so as to achieve the effect of high temperature sterilization.

Under normal circumstances, it may take 45 to 60 days. There will be a definite result, and it is best not to live for more than two months.

Generally, the fermentation process of these organic fertilizers only takes about 40 days.

Most organic fertilizer products are only composted and fermented for 15-20 days, and such products can only meet the harmless standard. The fermentation process of high-quality organic manure compost generally takes 45-60 days. This is because in the heating stage and high temperature stage in the early stage of composting, it will kill harmful microorganisms such as plant pathogenic bacteria, insect eggs, weed seeds, etc., but the main role of microorganisms in this process is metabolism and reproduction, and only a small amount of metabolites are produced, and these metabolites are unstable and not easy to be absorbed by plants.

Generally, it takes about 45-60 days of fermentation before it can be used. Farm manure will kill some harmful microorganisms such as germs, insect eggs, weed seeds and so on in the heating stage and high temperature stage in the early stage of composting, but it will not be humified until the later stage (cooling period) that the microorganisms it contains will carry out humification of organic matter, and a large number of metabolites that are beneficial to plant growth and absorption will be produced in this process, and this process generally takes about 45-60 days.

Fermentation of water and fertilizer is more particular, fermentation is not good, it is easy to burn seedlings, burn heels, you can add some strong compost starter fermentation water fertilizer, fermentation 5-7 days can be out of water fertilizer, the effect is very good, generally need more than a month, piled together, natural fermentation, low temperature in winter, it takes longer, if the film is covered, the time will be shortened accordingly.

Organic fertilizer refers to the process of converting waste organic matter into fertilizer through the fermentation of microorganisms under artificial control and certain moisture, C N and ventilation conditions. Through the composting process, the organic matter is transformed from an unstable state to a stable humus substance, and its compost products do not contain pathogenic bacteria, weed seeds, and are odorless and fly-free, which can be safely handled and preserved, and is a good soil conditioner and organic fertilizer.

There are two main meanings of fermentation:

1. Kill pathogenic bacteria, grass seeds, etc.

2. Through the process of mineralization and humification, the organic matter is converted into substances that are easily absorbed by plants. It also improves the texture of the soil.

Mature organic fertilizer generally requires two stages, namely the first high-temperature compost decomposition fermentation stage and the second aging stage. Unstable organic matter is transformed into stable humus through the process of decomposition and the action of microorganisms. The temperature change can determine whether it is ripe or not.

Let's talk about the first stage first: through the ratio of raw material matrix, the compost compost absorbs high oxygen, produces high temperature, reduces the degradable volatile solids a lot, gradually reduces the odor, and gradually changes the color of the compost pile, so it is necessary to maintain good aeration and moisture control.

Secondary composting: The temperature is initially reduced, the oxygen absorption rate is reduced, and the odor disappears completely.

Compared with the first compost decomposition, the second compost cannot be dispensed without, because the secondary compost can degrade the refractory organic matter, and the mesophilic microbial colony is re-established, which helps the organic fertilizer to decompose, reduce plant toxic substances and inhibit pathogenic bacteria.

Temperature rise stage: the temperature of organic fertilizer decomposition rises to 45, mainly actinomycetes, fungi and bacteria, mainly decomposing sugars and starch. Even active organisms, animals and animals are involved.

High temperature stage: the decomposition temperature reaches more than 45, the mesophilic microorganisms are inhibited, and the thermophil dominates. Soluble organic matter continues to be oxidized and decomposed, and complex organic matter (cellulose, hemicellulose, protein, lignin) also begins to be decomposed.

around 50 (thermophilic fungi and actinomycetes); around 60 (thermophilic bacteria and actinomycetes); 70 or so (most microorganisms are no longer adaptable).

The optimal ripening temperature is 55, because most microorganisms are most active at this temperature and are the most likely to decompose organic matter, and most of the germs, insect eggs, and weed seeds will be killed.

Cooling and reduction stage: Mesophilic microorganisms begin to multiply in large numbers again, occupy a dominant position, and further decompose the residual refractory organic matter. At this time, the microbial activity decreases, the oxygen demand of the compost decreases, the temperature decreases, and the compost gradually stabilizes.

Look at the freshness of the material, the summer is generally about 7 days, the winter will be a few days long, the fresh chicken manure and cow manure are easy to heat up, add some strong compost starter to heat up the next day, 2-3 days of deodorization, generally 7-10 days of fermentation and rot completely. The fertilizer effect is very good, not the faster the better, too fast may ferment and rot incompletely, and there will also be a situation of burning seedlings, so it is necessary to judge whether the fermentation and rot are complete before fertilization.

It generally takes about 50 days; Its main purpose is harmless, humification, and it is capable of producing a large number of microorganisms to metabolize various products.

Generally, it is stacked for about three months, and the purpose of fermentation is to kill the bacteria in the organic fertilizer and maximize the nutrition of the organic fertilizer.

It takes about 1-2 months. This allows microorganisms to decompose the soil and allow the soil to better absorb the nutrients inside.

The changes in the first, second, third, fourth and fifth weeks of making fertilizer are: the change in the first week is not obvious, and there is only a little smell of raw materials; In the second week, the orange peels, fruit peels, and vegetable leaves in the fertilizer bag began to mold; In the third week, the mold is blue-green, and the smell is more unpleasant when the area is enlarged; In the fourth week, all of them were moldy and foul-smelling; In the fifth week, the peel and leaves in the fertilizer bag will be melted into the soil and fermented to become fertilizer in the soil.

At present, the society advocates green environmental protection, and the concept of green agriculture and organic agriculture is deeply rooted in the hearts of the people. Making organic fertilizer can not only turn waste into treasure and reduce environmental problems, but also provide excellent quality fertilizer for agriculture. There are a wide range of raw materials for the manufacture of organic fertilizer, and the basic principle of production is fermentation.

There are many ways to make organic fertilizer according to the raw material** and the use of organic fertilizer, and here is a quick way to make it.

First, the material ratio.

Inoculation 1kg of special powder for fermentation of organic fertilizer such as Protogenus chinensis and 10kg of bran powder (corn flour, mushroom residue, etc.) are fully mixed into 5 tons of livestock manure and part of the straw or humus is added, and stirred evenly.

2. Water regulation.

The moisture content of the fermented material should be controlled at 50-60%. The simple judgment method is: grasp the mixed fermentation materials tightly, see the watermark but not drip on the fingers, and loosen it to the ground to spread it is appropriate.

If the water juice can be squeezed out and does not spread out when it lands, the moisture content is greater than 75%, and too dry and wet is not conducive to fermentation, so it should be adjusted.

3. Material stacking.

When making a pile, it can not be too small and too short, too small will affect the fermentation, the height of the flat-topped trapezoidal pile is in meters (spire conical pile rice), the width is 2 meters, and the length is more than 2 4 meters.

Fourth, the starting temperature.

The starting temperature should be better than 15 (it can be operated in all seasons, not affected by the seasonal climate and temperature in the north and south, and the fermentation should be started indoors or in the greenhouse as far as possible in winter, and the fermentation should be started according to the technician's guidance method in the northeast and other alpine areas).

Fifth, turn over the pile for aeration.

During the fermentation process, pay attention to proper oxygen supply and turning over the pile (when the temperature rises to 60 70 or above, it should be turned over in time, generally need to be turned over 3 times), the temperature is controlled at about 65, and the temperature is too high to have an impact on the nutrients.

Sixth, the fermentation is completed.

Generally after 48 hours of material accumulation, the temperature rises to 50 60, the third day can reach more than 65, at this high temperature to turn over once, under normal circumstances, there will be two high temperatures of more than 65 in the fermentation process, and the fermentation can be completed by turning over 2-3 times, and the fermentation can be completed within 10 normal times. The material is dark brown and the temperature begins to drop to room temperature, indicating that fermentation is complete. Spikes.

7. Organic fertilizer preservation.

1. Store in a cool, dry place.

2. Fermented organic fertilizer is mainly used as base (bottom) fertilizer, and the fertilizer is evenly spread before planting and turned into the soil. If strip application or furrow application is used, attention should be paid to prevent the phenomenon of burning seedlings in the centralized application of fertilizer, and the amount of fermented organic fertilizer per mu should be determined according to the actual situation of the crop field.

3. When fermented organic fertilizer is used as top dressing, it must be replenished in time.

4. When fermented organic fertilizer is used on dryland crops in the high temperature season, attention must be paid to appropriately reducing the amount of application to prevent seedling burning.

Organic fertilizer fermentation is more grinding, and Bipei is long.

Under normal circumstances, it takes one year for organic fertilizer to develop Huizi fermentation.

However, if it is in a place where the weather is particularly hot and the humidity is relatively high, it can also be fermented well in one summer.

Summary. Under normal circumstances, it takes about 30 days to ferment organic fertilizer with starter culture, and about 45-90 days to ferment organic fertilizer under natural conditions.

Under normal circumstances, it takes about 30 days to ferment organic fertilizer with starter culture, and it takes about 45-90 days to ferment organic fertilizer under natural conditions. State bumps.

Of course, in order to greatly shorten the fermentation time, it is possible to carry out (high temperature) fermentation in the heating irrigation, and add the starter culture at the same time, so that the lead bucket will take about 1-3 days, and the organic fertilizer can be fermented with laughter.

<> fertilizer fermentation time needs to be determined according to temperature, fermentation amount, water content, starter culture, generally the higher the temperature, the shorter the fermentation time, when the temperature is below 10, fermentation takes more than 3 months, when the temperature is above 10, it takes 1-3 months; The greater the amount of fermentation, the longer the fermentation time; The water content of 50-60% is more appropriate, too high or high will affect the fermentation time; If the starter culture is added, the fermentation can be completed in 10-20 days.

The time it takes for fermented soybean meal to become organic fertilizer depends on a variety of factors, including temperature, humidity, material ratio, and culture selection. Generally speaking, the time range for naturally fermented soybean meal to become organic fertilizer is between 2 and 4 months, and it takes about 15-20 days to ferment with professional strains (such as high-heat rotten bacteria sold on the market, multi-functional fecal water and fecal rapid deodorant starter and other products).

Temperature is a key factor in the fermentation process. The optimal fermentation temperature range is between 50°C and 70°C, which accelerates the decomposition of organic matter and the activity of microorganisms. Humidity is also important, in general, it should be kept between 50% and 60%, too high or too low will affect the effect of fermentation.

In addition, the proportion of ingredients also affects the fermentation time. In general, soybean meal should be mixed with other organic wastes (e.g. straw, kitchen waste, etc.) in a certain proportion to provide an adequate C/N ratio and nutrients**. The selection of strains is also important, and different strains have different decomposition rates and effects.
