What are the hazards of uncooked farmyard manure? How to ferment farmyard manure?

Because organic fertilizer is mostly composed of livestock manure, most of the animal manure has Schizocephalus, ciliates and their pathogenic bacteria. After penetrating the soil layer, the pathogen does not die, but lives again. This pathogen can cause further damage to food crops.

For example, in the roots of fruit trees in plantations, growth and development of nodulous material will be seen, which is the conclusion of ciliate injury. If this kind of ciliate outbreak occurs, it will not only consume the nutrients of the fruit tree, but also cause the death of the fruit tree. The results are also quite obvious.

The way of making alcohol organic fertilizers.

If human and animal manure is independently alcoholized, although alcohol is generated, many nutrients will be outflowed because of the high calorie, especially the evaporation of nitrogen; However, the stems and weeds are independently alcoholized, the fermentation time is long, and the nutrients are low after alcohol. Therefore, it is necessary to mix human and animal manure with stems and weeds, and use phosphorus fertilizer to produce alcohol to achieve the ideal practical effect. Bring pathogenic bacteria and parasites.

In addition to the grass ash, organic fertilizer is ignited by high heat, and other such as pig manure, chicken manure, sheep and cow manure, are discharged from the animal body. All contain bacteria and parasites in the animal's body, if it does not rot for a certain period of time.

Killing this pathogen and parasite and immediately applying it to the destination can lead to increased disease in crops. It cannot be digested and absorbed by crops at the same time. After getting out of bed immediately, it still needs to rot again in the field, which cannot be digested, absorbed and used by crops at the same time, which delays the necessity of crops.

Organic fertilizer is a very important chemical fertilizer for farmers, and it has a particularly good practical effect on the components that improve soil and improve soil fertility. In rural Yunnan, basically every household has an area with organic fertilizer, and all the organic fertilizer is piled up in one place, and it is used as base fertilizer when planting corn, wheat and other food crops.

Our family raises pigs every year, and the purpose of organic fertilizer is to make the manure that the pigs step on. The use of organic fertilizer can usually give abundant and sustainable nutrients to food crops, humic acid contains microbial flora, and the existence of dimensional element fertilizer can not only improve the loose air permeability of the soil, promote the development of rhizomes and robust food crops, produce organic chemical green and healthy agricultural products, and finally make farmers rich. If the use of organic fertilizer for food crops that has not been mellow, not only can not receive the above practical effects, but also may cause root burning, seedling fall, disease corrosion, etc., resulting in yield limiting damage.

It may cause seedling burning to crops, may make crops nutriently deficient and dwarf, and may cause pests and diseases to overflow; After the farmyard manure is made, it is placed on a flat ground and it is tampled and fermented.

Unfermented organic fertilizer may contain harmful substances such as germs and insect eggs, and unfermented organic fertilizer burns seedlings. One of the fermentation of farmhouse fertilizer is to apply biological strains to manure in the fermentation pit, and maintain a suitable temperature and humidity during the fermentation process, and add good bacterial fertilizer or fungi.

It may cause plant decay, seriously affect the normal growth of plants, must be exposed to the sun, and the fermentation time must be long enough.

The application of farm fertilizer in rural crops is very cost-effective, and it is also very rich in nutrients, so how long should the fermentation time of farm fertilizer be? What are the precautions for fermentation? Let's talk about it for you.

Generally speaking, the fertilizer water can be produced after 5-7 days of farmhouse fertilizer fermentation, but during this period, a reasonable fermentation process and precautions should be mastered.

Precautions for farmhouse fertilizer fermentation: 1. Temperature.

The temperature of the inner layer of farmhouse fertilizer can reach more than 80 degrees, but if the temperature is too high, it is not good for the theme activities of microorganisms, and if the temperature is about 70 degrees, it will lose its charm if it is too hot. Therefore, the temperature of the high temperature link should be adjusted at 50-60 degrees, and the temperature of the thermal insulation link should be adjusted at around 30 degrees.

2. Moisture. In order to better improve the quality of humus, the moisture content of raw materials should be controlled below 70% before fermentation. When the moisture content is too low, the microorganisms lose their vitality, and when the moisture content is less than 30%, the microbial chemical reaction rate is significantly reduced. Therefore, it is more suitable for fermentation of raw materials with a moisture content of 65-70%, and it should be adjusted when the moisture content does not have this category.

3. The farm fertilizer applied by many farmers is mostly dominated by farm fertilizer, and the content of crop straw (corn straw, corn straw) is large, and other mixed substances are not suitable for higher than 10%.

4. In the case of fermentation, it is necessary to ensure sufficient fermentation time, and it can not be applied before manure, and it takes 50 to 60 days to carry out fermentation.

Can farmyard manure be used without manure? Unseasoned farmyard manure cannot be used, otherwise there will be many problems:

1. Unprepared farm manure usually carries a large number of bacterial larvae, which is very easy to cause peach tree rhizome diseases, and will continue to pollute the environment.

2. The nutrients of farmhouse fertilizer that have not been brewed are mostly in an organic chemical state, which is not easy to digest and absorb by peach trees, which will lead to damage to chemical fertilizers.

3. When farmhouse fertilizer undergoes microbial dissolution and fermentation in the soil environment, it will form a lot of calorific value, which is very easy to burn the porous roots of peach trees.

4. Farm fertilizer will absorb a lot of nutrients when it undergoes microbial dissolution and fermentation in the soil environment, resulting in a short-term nitrogen deficiency in peach trees.

5. Farmhouse fertilizer must go through a whole process of microbial dissolution and fermentation in the soil environment, resulting in backward fertility, which cannot be consistent with the rhythm of peach tree growth and development and the stage of fertilizer demand, and cannot play the purpose of fertilizer, and even leads to adverse harm. Therefore, farmyard manure must be used only after manure.

The temperature of the high temperature stage should be controlled in the range of 50-60 degrees, the temperature of the post-ripening insulation stage should be controlled at about 30 degrees, the moisture content of the raw materials before fermentation should be controlled below 70%, and sufficient fermentation time must be ensured during fermentation, and the agglomerate structure in the fully decomposed farmhouse fertilizer should be loosely dispersed.

Try not to mix with soil, but also pay attention to the fermentation process, pay attention to the temperature, but also pay attention to the activities of various microorganisms, pay attention to the duration of fermentation, and so on.

Pay attention to the time of fermentation, pay attention to the temperature of fermentation, pay attention to the surrounding environment, it is best to put it in a safe place, away from water sources, and away from crowds.

Method of fermenting farmhouse fertilizer: Ferment human and animal manure separately, although the temperature of the fermentation block is high, it will lose a lot of nutrients, especially the nitrogen volatilization is more, and the stalks and weeds are fermented separately, the fermentation time is long, and the nutrient content after fermentation is low. Therefore, human and animal manure should be mixed with stems and weeds, and superphosphate fermentation can achieve the desired effect.

Carries bacteria and eggs. In addition to plant ashes, farm manure can also be burned at high temperatures, and other excrements such as pig manure, chicken manure, cow and sheep manure, etc., can also be excreted from the animal's body.

Both of them carry bacteria and eggs from the animal's body. If these bacteria and eggs are killed, they are applied directly to the ground without a certain period of decomposition and fermentation, which will aggravate crop diseases and pests. It cannot be directly absorbed and utilized by crops.

Falling directly to the ground, it can also rot in the field, and cannot be directly absorbed by crops, delaying the growth needs of crops. Produce underground parts that are not conducive to the growth of crops. Immature organic matter ferments and heats up after entering the soil.

During the continuous fermentation process, a large amount of organic acids, heat and locally high concentrations of ammonia salts are decomposed, causing damage to the root system of crops. Crop roots cannot withstand the damage of high temperature, high salt and high acid, and will burn the root system, causing crops to wilt after losing water.

Competition for crops, water, and fertilizers. During the fermentation and decomposition of undecomposed organic matter, the multiplication of microorganisms will compete with crops for water and fertilizer, making it difficult for crops to absorb water and nutrients, but affecting the growth of cropsToxic gases are released and harmful to crops.

During the fermentation of organic fertilizer, toxic gases are released, which can harm crop roots and seedlings and breed underground overwintering pests.

Raw organic fertilizer contains a large amount of animal organic matter, which has become a wintering place for a variety of pests, which is not conducive to the control of pests and diseases. In the past, the fermentation of poultry manure was to use a large cement pool (cement brick) with bricks, to dry the poultry manure to reach semi-dry, the son entered the septic tank, compacted, covered with plastic sheeting, sealed with mud, do not let the air leak, fermentation preparation for ten days or so in hot weather, if the weather is cold, it takes 20 to 30 days. Fermented organic fertilizer, growing fruits, very sweet and delicious!

Unrotted farm manure has pests and eggs. It can be covered with plastic sheeting, fermented and rotted at high temperature. It is easy to cause the burning of roots and seedlings of crops, and the unrotted farm manure contains various pests and diseases, and the nutrients in the unrotten farm manure cannot be completely absorbed and utilized by plants

To pile up the fertilizer layer by layer, add appropriate water to keep it moist, and then let the outside temperature stay at about 20 degrees, and it will be ready to rot after 6 months. Eventually, it will lead to the burning of seedlings, which will cause nutrient loss from the land and pollute crops.

Fertilizer can be mixed with soil, and then exposed to the sun for fermentation, and if the fertilizer is not done, it is easy to cause damage to the roots of plants, so some plants will lodging.

Methods of pests and diseases: In human and animal excreta, there are many kinds of germs and parasite eggs. What we can see with our eyes is that when digging up animal manure, it is common to dig up grubs.

Naturally, there are more pests and diseases; When the stable is wet and cold, sprinkle some sandy soil on it. In this kind of soil, some germs will be brought: such as brown spot pathogens, root nematode pathogens, etc.; In the stems, it will contain some germ larvae; Wild grasses not only contain pests and diseases, but also have a large number of grass species.

Therefore, the use of farmhouse fertilizer must be reused after manure, so as to be beneficial to the digestion, absorption and full use of crops, and will not get twice the result with half the effort.

Fresh animal manure is slowly fermented in the soil at first. In the case of fermentation, a lot of calorific value and a part of nitrogen dioxide will be emitted, and it is also necessary to clean up the nutrients in the soil. It will cause damage to the plant flowers and burn the seedlings.

Because farm manure is mostly composed of livestock and poultry manure, most of the animal manure has Schizocephalus, ciliates and their pathogens remaining. After being introduced into the soil, the pathogenic bacteria do not die, but live again.

Compete for crop fertilizer and water. In the case of unfermented organic matter being fermented and rotten, considering the breeding of microbial strains, this microbial strain will compete with crops for water and organic fertilizer, resulting in difficulties for crops to digest and absorb water and nutrients, which will harm the growth and development of crops. Toxic gases are released and damage crops.

In the case of fermentation of organic fertilizer, some harmful gases will be released, and the roots and young seedlings of crops will be harmed by this toxic gas. Breeding for underground overwintering insect infestations. Unfermented organic fertilizer is rich in a lot of animal organic matter, which becomes a winter site for many insect pests, which is not good for preventing pests and diseases.

The use of manure fermentation is a little better farmhouse fertilizer can usually give crops abundant and sustainable nutrients, humic acid contains microbial flora, the existence of size element fertilizer effect can not only improve the loose air permeability of the soil, promote the development of rhizomes and robust crops, produce organic chemistry green and healthy agricultural products, and finally make farmers rich. If you use farmhouse fertilizer that has not been fermented for crops, not only can you not receive the above practical effects, but also may cause root burning, seedling inversion, corrosion of pests and diseases, etc., resulting in yield restriction damage.

Farm fertilizer can accumulate some leftovers or manure in life, and can be used as fertilizer after fermentation.

It is necessary to pay attention to the light, so that the fermentation can be carried out better, and the non-fermented farm manure may cause the plant to rot.

Natural accumulation and fermentation When the farmhouse manure is fermented and rotted, you can choose the method of natural accumulation and fermentation, regularly clean the poultry enclosure, and concentrate the manure on the farmland or open land where the cultivation is suspended, and receive sunlight. Unrotted farm manure often contains a large number of germs, insect eggs and grass seeds, which can easily cause crop diseases, insects and weeds, and also pollute the environment.

<>1. Select the site: choose a plot with flat terrain, convenient transportation, and sufficient water sources around it as the fermentation site, and the fermentation raw materials are leaves, dead grass, human and animal manure, crop straw, etc. 2. Mixed raw materials:

The raw materials are mixed and stacked in one place, with a width of 2 meters and a height of meters, and then covered with plastic film. 3. Turning the pile regularly: turning the pile once in a while, and when the surface of the compost appears fungus white hair, it will be compacted and sealed.

1. How to ferment and rot farmhouse fertilizer

1. Choose a venue.

Choose a plot or roadside with flat terrain, dry terrain, convenient transportation, and sufficient water sources around as the fermentation site, and the fermentation raw materials can use human and animal manure, leaves, dead grass, crop straw, domestic garbage, etc.

2. Mixed raw materials:

After preparing the raw materials, mix them and pile them together, the height of the compost should be in meters, the width of the bottom should be 2 meters, the length is not limited, and the degree of fullness is appropriate to the actual degree of natural accumulation. After the raw materials are stacked, they are covered with plastic film to achieve the effect of heat preservation and moisturizing.

3. Turn over the pile regularly.

1) After 20 days of composting, the first turn is carried out, and the second turn is made after an interval of 20 days.

2) When fungal white hairs appear on the surface of the compost, it means that the compost has begun to ferment, and the compost should be compacted and sealed with plastic film.

4. Precautions.

1) In the process of composting, do not mix the soil to avoid slowing down the fermentation rate of fertilizer, which will affect the compost heating and prolong the time of decomposition and fermentation.

2) During the compost decay period, the temperature of the compost pile should be controlled at 70-80.

2. Is farmhouse fertilizer an organic fertilizer?

1. Farmhouse fertilizer belongs to organic fertilizer, which refers to a variety of organic fertilizers collected, made and planted in rural areas, which can provide a variety of nutrients for plants and crops after use, and can also improve soil structure and adjust the pH of the soil, which is very beneficial to the growth of crops.

2. Common farm fertilizers in life include manure, livestock manure, green manure, compost, mud manure, manure, grass ash, etc., most of these fertilizers can only be used after decomposing treatment, otherwise they will cause fertilizer damage and are not conducive to the growth of crops.

3. Unrotted farmhouse fertilizer generally contains a large number of germs and insect eggs, which is easy to cause diseases and pests of fruit tree roots after use, and will cause environmental pollution.
