How to ferment bark to make a high quality soilless culture medium?

1. Material preparation and pretreatment.

1. 500 kg of bark, 25 kg of dry chicken manure or livestock and poultry manure, 5-10 kg of urea or thiamine, 5 -10 kg of lime.

2. Mix dry chicken manure or livestock manure, urea and thiamine into the bark material to reduce the carbon ammonia to below 40.

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

4. Fully watering the buckle film and covering (stuffing) the pile for 2 3 days to make the moisture content reach between (50 5)%. 5. 1kg of Gymboree bark fermentation auxiliary, dilute and mix with bran to form an incremental fungus agent. Evenly carry the mixed calboree increase agent into the mixed bark mixture, and pour it several times to evenly adsorb the fungus to the fermented product.

This process is called "inoculation". After inoculation, the material is piled up into a large pile, covered with mulch, and placed naturally for 6 12 hours of pretreatment. Promote the zoning effect of the fungus agent, so that the Gymboree bark fermentation aid is fully adsorbed into the material to be fermented.

2. Fermentation. 1. After the pretreatment is completed, the fermented products are stacked into a large pile of 1 high, and covered with covering to keep warm and moisturize.

2. The first fermentation. Fermentation is carried out in two stages, the first is from the beginning of fermentation to 25 to 30 days, and the heat preservation and moisturizing measures should be strengthened to promote the saccharification of the fermented product. After 5 7 days of fermentation, the fermentation temperature reaches 45-50 degrees, and when white hyphae appear on the surface of the fermented product (more than 2 days), the first overturning is carried out, and then the fermentation is continued, so that when the cumulative fermentation temperature reaches 80 90 degrees, the second fermentation period (the second inversion) is entered.

3. Second fermentation. Note that the water content of the fermentation product is generally controlled at about 60%, and when the water is insufficient, 5% urea solution can be poured comprehensively. Then the thickness of the accumulation is appropriately increased, re-piled into a large pile, and the fermentation continues, after a temperature of 65 for 2 weeks.

After 3 weeks at a temperature of 60, when the cumulative fermentation temperature reaches 80 100, the fermentation can basically be stopped. The functional microorganisms in the Gymboree bark fermentation auxiliaries fully ferment and decompose the bark, which can remove the components such as carbolic acid and tannic acid that are harmful to plant growth, and greatly enhance the physical properties, commodity properties and economic value of the fermentation products.

Abstract: Soilless culture substrates have been more and more widely used in the vegetable industry. Because resource products such as grass peat substrate are seriously restricted by factors such as environmental protection and transportation costs, the use of some industrial and agricultural wastes and scraps to ferment into vegetable and flower seedling substrate is favored by growers.

There are many raw materials that can be fermented into a substrate, and general materials such as weeds and bark are easier to ferment, but sawdust is the most difficult to ferment with bark, especially sawdust, which can not be dealt with by general starter culture. This article takes Gymboree fermentation auxiliaries as an example to briefly describe its operation process.

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.

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 Answer: After making small pieces, soak in water, soak all of them, seal them in a plastic bag, moisturize and expose them to the sun in the high temperature season, ferment them after a summer, and then dry them for preservation, and soak them in water before use. Follow-up:

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

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

Answer: Absolutely, 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.

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.

Crushing, adding starch and strains mixed fermentation.

Boil it with boiling water for at least 30 minutes, then take it out and spread it out to dry, and put it for 24 hours according to the ratio of 1:300 (if you are willing to use Xishuo 1:1000 times liquid), this is the bark is also half dry, soak the bark in the prepared water, and it is advisable to submerge the bark with water.

Soak for 24 hours and drain and place in non-metallic containers such as plastic buckets and water tanks, the mouth of the cylinder should be wrapped with plastic sheeting, leaving only a few eyes to deflate, put it in the sun, generally 30 days can be used, with the liquid soaked in Xishuo can be used for 20 days, the bark of this is boiled with boiling water, which is conducive to the decomposition and fermentation of fungi.

Fermentation refers to the process of preparing the microbial bacteria themselves, or direct metabolites or secondary metabolites, with the help of the life activities of microorganisms under aerobic or anaerobic conditions. Fermentation is sometimes referred to as fermentation, and its definition varies depending on the occasion in which it is used. Fermentation usually refers to a certain decomposition process of organic matter by living organisms.

Fermentation is a biochemical reaction that humans were exposed to earlier, and is now widely used in the food industry, biology and chemical industries. It is also the basic process of bioengineering, i.e., fermentation engineering. Research into its mechanism and process control continues.

Anaerobic respiration of microorganisms such as yeast and lactic acid bacteria is also called fermentation.

Resources.

Dried pine bark: The fermentation method of pine bark is relatively simple, if it is pine bark that has been dry for a long time, then it can be used directly after crushing, pay attention to the pine bark that must be completely rotted. After crushing, the fertilizer can be mixed into the soil when the family grows flowers.

Introduction:

If it's fresh pine bark, make it into small pieces, soak it in water, wait for the moisture 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. Pine bark is the most suitable for cultivating orchids, and you may wish to try it if you raise orchids at home, and the fertilizer made from willow bark is no less than those organic fertilizers for the growth and development of orchids.

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.

Soilless substrate refers to a certain proportion of peat, perlite (or vermiculite), fermented bark powder, sawdust and an appropriate amount of mineral fertilizer. It is worth noting that the organic matter in the substrate, including bark, sawdust, garbage, organic scraps of animals and plants, etc., must be fermented, otherwise, in addition to nutrient loss, it will be forced to passively ferment in the roots or fields of crops because of organic matter, resulting in root burning, seedling burning and other phenomena, resulting in major economic losses such as dead seedlings. Gymboree substrate fermentation additives are specially developed for the needs of the seedling and flower industry, and have unique functions in fermenting bark sawdust, which can greatly shorten the fermentation time, reduce nutrient loss, eliminate the phenomenon of burning roots and seedlings, balance nutrients, and protect the environment, safety and health.

Traditional natural fermentation, such as sawdust bark generally takes one or two years, livestock and poultry manure is fast for more than half a year, and the rotting is uneven, not thorough, nutrient loss pollutes the environment, and the general materials with Gymboree type 1 fermentation additives can be fermented in about three weeks, resulting in a beautiful appearance (brown or black), pleasant smell (remove chicken manure and pig manure and other fecal odors, or other kinds of garbage scraps of rancid odor), nutrient-rich substrate, is widely used in high-grade orchid pine bark substrate fermentation, roof greening, In addition to good ecological effects, the treatment of residual branches and leaves in golf courses, park property communities, and other general seedling and flower industry substrate fermentation treatment, its economic benefits are very considerable, and the value is several times.
