1. What are the differences between mechanism charcoal and charcoal

Two types of charcoal are divided into two types, one is the rustic charcoal, that is, the traditional charcoal, which is obtained by the burning of wood; the other is mechanical charcoal, which is squeezed and processed by wood fragmentation. So what is the difference between them?

1. What is charcoal

charcoal is not completely burned by wood or wooden raw materials, or heat solutions under the condition of isolation of air. The remaining dark brown or black porous solid fuels are the immeasurable non -pure carbon that keeps the original structure of the wood and the impure carbon in the hole.

2. What is mechanism charcoal

Mechanical carbon is a charcoal rod -shaped material made of wood fragmentation and squeezed processing. It is a charcoal made of machine.

3. The difference between mechanical charcoal and charcoal

(1) Different sources of raw materials: Mechanisms are mainly one or more or more by the mechanism of charcoal, carbon, Peanut shell, cotton shell, corn stalks, sorghum stalks, Beans stalks, sawdust, wood chips, granular shells, coconut shells, etc.Materials.Traditional charcoal is fired from wood, and it is commonly used.

(2) Different production principles: Mechanical charcoal is a carbon rod that contains wood containing wood, placed in the machine, which is an artificially synthetic fuel stick.charcoal is made of wood directly after carbonizing wood.

(3) Different combustion process: The mechanism charcoal is compressed by a variety of materials, so it is slow to burn, which means that its combustion time is long, but its burning value is low, and the heat generated is not very large.The charcoal composition is relatively single, the burning value is very large, and the heat generates a lot, but its burning speed is fast, and the continuous combustion time is not as long as the mechanism is charcoal.

2. Which of the mechanical charcoal and charcoal is better

Traditional charcoal is gradually banned because the traditional charcoal needs to cut off the high temperature of trees and pollutes. Most of the charcoal on the market is now the mechanism charcoal. Compared with the mechanism of charcoal and charcoal, the advantages are mainly:

1. More environmentally friendly

Do not cut down trees, use wood products waste to produce, become waste into treasure, and do not destroy the ecological environment.

2. High energy

Mechanical charcoal fixed charcoal content is about 80%, the heat value is 7500-8000kcal/kg, while the fixed carbon content of charcoal is low, and the thermal value is about 6500kcal/kg.

3. clean and hygienic

Mechanism charcoal -free and charcoal -free head, burning without sparks, during the burning period, the ash naturally falls without floating, 3%or 6%of the gray portion or 6%is less ash and flammable.

4. It is more convenient to use

Mechanism has a unified length and size, and the hollow or solid structure is more reasonable, which is conducive to burning and use.

5. The water content is lower

The moisture content of mechanism charcoal is about 5 %, which is lower than ordinary charcoal, and the combustion performance is better.

In summary, mechanism charcoal is better than ordinary charcoal in terms of performance and environmental protection.

How to make Fertilizers for expired Milk powder

Expired Milk powder has the following steps: fermentation process, fermentation complete, and dilution of water.

1. Select fermentation container:

The fermentation container can choose a clean plastic container. It is not recommended to use a glass bottle. This is because the Milk powder will generate gas during the fermentation process. If the exhaust is not Smooth, the glass bottle will burst.When fermenting with plastic containers, the bottle cap should not be twisted too tightly, leaving a gap, which is convenient for the gas generated by the fermentation.You can put some orange peels in the bottle to eliminate some odors.

2. Fermentation process:

Pour the expired Milk powder in the plastic container and determine the amount of Milk powder according to the size of the container.Add some rice water to the container to ferment Milk powder faster.Then use chopsticks to stir Milk powder and rice water well, and seal it and ferment under the sun.summer is usually fermented outdoors and the temperature is low in winter, and it should be fermented in a warm place indoors, but the time will be slightly slower.

3. Fermentation:

By observing the changes in the liquid, it is determined whether the fermentation is successful. When there is a significant layered in the plastic bottle, the color of the liquid is bright in color, and the lower layer has white solids like tofu, indicating that the fermentation may be successful.At this time, open the bottle cap. If you smell a sour smell, it proves that the fermentation is basically completed and can be used.

4. Dilute water with water:

The fermented solution is full, with high concentration, and it is easy to burn the root system directly. Therefore, it can be mixed according to the ratio of 1:20 before use, and it can be sprayed directly on the surface of the leaves to ensure that the branches and leaves have a stronger growth.

Can I make Fertilizers in the expiration Milk powder?

Can.

1. Expired Milk powder can be used as Fertilizer, but dairy flower Fertilizer is only suitable for Fertilizer plant, such as Milan, jasmine, rose such as rose.Orchids need to be used with caution. A large amount of protein contained in Milk powder can synthesize "nitrogen" with organic ingredients such as chlorophyll, so it can be used as flower Fertilizer.

2. If the expired milk already has a clear acid rot, you can use it to pour the flowers at this time, dig out a shallow gap on the edge of the flower soil, pour into the diluted milk and then cover it with soil.The fermented milk has a certain nutritional value to plant growth, which can supplement the nutrition required by plants.The protein in the expired milk after fermentation is decomposed into inorganic salts by bacteria for plant absorption.

What are the nutrients for expired Milk powder to do Fertilizers?

1. The main component of Milk powder:

The main component of Milk powder is protein. In the past, the content of nitrogen element in Milk powder was calculated, so as to estimate whether the protein content in the Milk powder meets the standard.The average mass score of nitrogen in protein is about 16%.It can be seen that the amount of nitrogen -containing elements in Milk powder is still very high, and crops and vegetables need a certain amount of nitrogen fertilizer during growth. Therefore, Milk powder can be used as Fertilizer for vegetable fields.However, it should be noted that Milk powder must be fermented for Fertilizer.

2. The role of nitrogen fertilizer in vegetables:

When spring farming is spring farming, whether it is Wheat, rice, apple trees, pear trees and various vegetables, they need to fertilize, including nitrogen fertilizer.The effect of nitrogen fertilizer on plants has the following two points:

Nitrogen is the main component of protein in crops. nitrogen fertilizer can improve the nutritional value of crops and increase the protein content in fruits and seeds. It can be said that without nitrogen elements, proteins cannot be formed in plants.Do not open the participation of protein.

The use of nitrogen fertilizer for vegetables can make the plant grow strongly, prevent yellowing and dryness of the leaves, and nitrogen fertilizer can promote the growth of the plant root system and increase branches.

Note: If the use of nitrogen Fertilizers is severe, it can lead to precocious precocious crops and vegetables and decrease in yield.If the nitrogen fertilizer is used too much, the plant growth can be too strong, the leaves are thick green, it is easy to fall, and the crop yield will be reduced.Therefore, the use of nitrogen fertilizer requires strict control.

[seed preservation temperature] How long can the seed cold storage storage be reached?

Validity of vegetable seed preservation

Vegetable seed germination rate is very related to the preservation period, different vegetable species, and their preservation years are different.

tomato:Generally, it can be stored for 3-4 years, and the longest does not exceed 4 years. Otherwise, the method of reducing the bud rate will be reduced. The method of identifying the old and new seeds is that there are furry on the new seeds and tomato flavors.

Cucumber:At most 2-3 years, which exceeds this period, the period of the deadline is generally reduced by 20-30%. Even if it can emerge, some often have no true leaves after seedlings, and it is not easy to survive.

eggplant:seeds that are generally within 6 years can be used. The new seeds are shiny, and the old seeds reduce the luster according to the storage period.

chili:It must not exceed 3 years, otherwise the bud rate will be reduced, the bud rate of 2 years will be reduced by about 10%, and the storage of three years will be reduced by about 30%. The new seeds are golden yellow, and the Chen seeds are apricot yellow.

Scallion seed:In the summer, the green onions must be used to use the new seeds of the year. If the seeds of the aged, the green onions will smoke moss.The spring onion can be produced in the first year.

coriander:It must be stored for one year, but the storage time should not exceed 3 years.Otherwise, the fragrance will become smaller.

celery:It can be stored for 3 years. The seeds that year cannot be used in that year, and it must be used for one year.

Chinese chives:The new seeds were good at that time, and the germination rate of two years was greatly reduced.

Chinese cabbage:It can be stored for two years. The seeds harvested in that year can be sowed in that year, but if more than two years, the seedling rate is reduced by 20-30%, and the disease resistance is low.

seed preservation temperature

During the storage period, the percentage of the relative humidity of the air in the storage room plus the temperature((Hua'sCureThe number should not be greater than100Otherwise, it will affect the storage effect.Onions, broccoli, carrots, lettuce, tomato, eggplant and other vegetables are stored in20Percent(66T)The temperature and air relative humidity of the air is50Under the conditions, it can be stored safely.The seeds of cauliflower are stored in17(62..6F)Relative humidity with air is35Under the condition,4During the year, the seeds of seeds remain unchanged.When the temperature is5, the relative humidity of the air is45%one50At %, many seeds can be stored10Year or more time.If the temperature and the relative humidity of the air can be reduced, the effect of seed preservation can be improved.

The maintenance of the seeds of seeds is also closely related to the content of the seeds itself, and reducing the moisture content can extend the seed life.According to research, the moisture content of the seeds decreasesL%, Temperature decrease5..6C can double the life of the seeds.

Of course, the seeds of different varieties of the same vegetable have different reactions of storage conditions.

According to the above principles, the seeds of vegetables are effectively stored effectively((Or other crop seedsCureThere are also many methods. At present, the low -temperature drying storage method or sealing low -temperature storage method is used internationally internationally. The former is mainly to build a low -temperature drying seed library to store seeds.storage at low temperature.According to the test, the seeds of vegetables with low water content are-4storage at low temperature at low temperature20In the year, he still had a high life.Moso seeds with low water content are in a closed container and stored in2Under , pass through10After the year, there is almost no reduction of its living power.

In addition, Chinese cabbage and cabbage are not affordable"Original species" seeds, stored with silicone dryer, put in4-5storage can be stored under the condition ofLOOver the year.
