How is the bark fermented? How the bark can be fermented

Satisfactory answer: 17 levels2012-01-10 Not all pine bark can be nutritious substrates, I divide pine bark into three categories: one is basically undegreased or slightly degreased and degraded pine bark; the second is moderately degreased and degraded pine bark, which we often think of as "rotten"; The third is the deep degreasing and degraded pine bark, that is, after more than 3 years of sedimentation or natural state in the trunk wood has been decayed, the pine bark has begun to ash from the surface and the inside at this time, and the pine bark at this time is the best.

The pine bark I use is basically the third type, and it is also soaked for a period of time, chopped and then boiled with additives. Don't underestimate the boiling process, not only to ensure the cleanliness of the planting material, but also because under the action of high temperatures, some components in the bark can be broken down into nutrients that are conducive to the absorption of orchids. The treated pine bark is best used to grow orchids.

Here's what it looks like after it's done:

Follow-up question: I know your Lan friend from CCCC. Follow-up:

What I asked was how to ferment the bark OK: After making it into small pieces, soak it in water, soak it all through, seal it with a plastic bag, moisturize and expose it to the sun in the high temperature season, ferment it after a summer, and then dry it for preservation, and soak it in water before use. Follow-up:

Doesn't fermentation require the decomposition of microorganisms to kill microorganisms when exposed to the sun? : At the same time of sealing and moisturizing and exposing to the sun, high temperature and humidity, microorganisms are very active, and the fermentation and decay speed is fast.

How can there be no microorganisms to participate in decomposition? Follow-up: Can you reach the third type you said?

Surely, my own pine bark is made like this, and the degree of fermentation is of course related to the temperature at which you ferment. Observe it, the color turns black, it's almost the same.

Pine bark fermentation in this way is the easiest, fastest, and best for orchids!

Bark fermentation cultivation medium technology:

The bark is characterized by its light weight, high water retention capacity, high organic matter content, high carbon-nitrogen ratio, and generally a pH value in between. In general, the C/N ratio of pine bark is generally 135:1, and the Cn of conifer bark is between 150 and 300.

Among them, the C n of larch bark is as high as 494. All carbon, all nitrogen. In addition to the cellulose, hemicellulose, lignin and other trace elements of wood, the bark is also relatively rich in carbonic acid, tannic anhydride and other substances harmful to plant growth, as well as polymer lignoic acid.

At the same time, because the bark has strong antibacterial and ant resistance, and is not easy to be soaked in water and decay, it is one of the organic materials that are difficult to ferment, and it is difficult to deal with general fermentation aids. However, the use of bark fermentation auxiliaries can achieve more desirable results.

1. Dried pine bark: If it is pine bark that has been dried for a long time, it can be used directly after crushing, and it must be completely rotted pine bark. After crushing, the fertilizer can be mixed into the soil when raising flowers at home, and then add some coarse sand and other substances to make a base fertilizer for plant growth, which can promote the growth of plants.

2. Fresh pine bark: If it is fresh pine bark, then make it into small pieces, then soak it in water, wait for the water to completely penetrate the pine bark, and then find a thick plastic bag and seal it. Maintain the humidity of pine bark, see the sun every day, sprinkle some rice water, let it ferment, the shortest time is more than half a year, if the fermentation is not sufficient, the impact on the plant is fatal, so we must pay attention to the complete fermentation.

1. Rapid fermentation method of pine bark1. Put the pine bark into a clean plastic bag, add some fertilizer and water to it, use a tool to tie the mouth of the bag tightly, do not let it contact the air, place it in a place with sufficient light, and wait for about a month to use.

2. The second fermentation method needs to crush the pine bark, add some chicken manure, urea and lime, and add an appropriate amount of fermentation aids after it is wet, stir it evenly with a tool, and cover it with a cover.

Wait for about 12 hours and stir again, during which time you should pay attention to moisturizing and heat preservation, the temperature during fermentation should be controlled at 40 45, turn it every half a month or so, and wait for about 2 or 3 months to ferment.

No matter how the ratio is possible, as long as you have local resources, you can get the fermentation formula is OK, Kangyuan Oasis such as Golden Fungus Feed Fermented Chicken can almost ferment distiller's grains, soybean meal, sugar residue and other kinds of organic matter that can be fed, the fermentation power is strong, the key is not what kind of formula is used for fermentation, users can design their own fermentation material formula according to their own local resources, only need to master two points:

1.There needs to be a little energy feed in the fermented material to provide the power for microbial growth and reproduction (mainly corn flour, potato flour, wheat flour, and bran bran about 1 10%)

2.For example, after you have designed your own fermentation formula, you need to simply calculate the nutritional value of the fermentation formula you designed, such as how much simple protein is and how much energy is approximately, and then match it with other feed ingredients to feed the pigs. For more details, you can search for a technician for consultation.

Kangyuan Oasis.

1. How to prepare materials and pre-treatment:

1. Prepare 1 cubic meter of bark, 25 kg of dry chicken manure or livestock and poultry manure, 5 to 10 kg of urea or thiamine, and an appropriate amount of lime.

2. Pour dry chicken manure or livestock manure, urea and thiamine into the bark material and stir until the carbon and nitrogen ratio drops below 40.

3 Because the bark of conifers contains high acidity, it is necessary to add an appropriate amount of lime and adjust the pH to 5.

4. Fully water, buckle the film, and cover the pile for 2 to 3 days to make the moisture content reach between 45% and 55%.

5. 1 kg of bark fermentation auxiliary, kg of rice bran are diluted together and mixed well, and prepared into an incremental bacterial agent. The mixture is evenly sprinkled in the bark mixture and stirred several times to evenly adsorb the fermented product, a process called "inoculation".

After the inoculation is completed, the material is piled up into a large pile, covered with mulch, and placed naturally for 6 to 12 hours for pretreatment to promote the octosibly effect of the fungus, so that the bark fermentation aid can be fully adsorbed into the material to be fermented.

2. How to ferment:

6. After the pretreatment is completed, the fermented products are stacked into a large pile of 1 to a height, and covered with mulch to keep warm and moisturize.

7. The first fermentation. Fermentation takes place in two stages. The first time is the beginning of fermentation to 25 to 30 days, should strengthen heat preservation, moisturizing measures, promote the saccharification of the fermented product, after 5 to 7 days of fermentation, so that the fermentation temperature reaches 45 to 50, when the surface of the fermentation appears white mycelium, begin to pour, pour.

Fermentation is then continued until the cumulative fermentation temperature reaches 800 to 900 °C, and the second fermentation period begins.

8. Second fermentation. Pay attention to make the fermentation water content generally controlled at about 60, when the water is insufficient, you can fully water 5% urea solution, and then increase the thickness of the accumulation appropriately, re-pile into a large pile, continue to ferment, after two weeks at a temperature of 65, three weeks at a temperature of 60, when the fermentation temperature reaches 800 to 1000, you can stop fermentation.

Natural fermentation. The method is very simple, pile it outside, water it thoroughly (it is best to pour some human urine), cover it with plastic film for a year, and the fermentation is completed. If you want to speed up fermentation, add a starter culture.
