Plant ashes:
Plant ashes are weakly alkaline, so it is best to use them sparingly. If you really need to, you can use water soaked in plant ashes.
First use the rice water and plant ashes to ferment and then water the flowers.
Coal:
1. Increase the soil temperature
After applying charcoal powder to the soil, the black charcoal particles absorb heat energy from the sun, which can increase the soil temperature by several degrees Celsius, promotes seed germination. In particular, it can promote the germination of seeds that are difficult to germinate and increase the germination rate.
2. Improve the soil
After applying charcoal powder to the soil, rhizobacteria can be generated on the surface of the charcoal, thus forming agricultural soil suitable for growing plants and avoiding hasinsi -called “continuous tillage” “Hinder” and charcoal can improve the growth, color and taste of grains, beans and vegetables.
3. Maintain soil moisture
When the relative humidity is above 50%, charcoal can quickly absorb about 20% of the water and can be used to maintain soil moisture. At the same time, it can also improve the air permeability and drainage of the soil, providing a good living space for microorganisms beneficial to plants.
4. Slow release agents for pesticides or fertilizers
Use the adsorption capacity of charcoal to maintain a balanced state of pesticides and organic fertilizers. With this balance, pesticides or fertilizers can be released slowly over a considerable period of time. and are not easily evacuated by rainwater runoff.
In addition, charcoal can equalement modify the pH of the soil, increase the C02 content of the soil, absorb harmful metals present in the soil and increase the activity of soil microorganisms.
There are countless holes in the charcoal. These holes have the function of adsorbing various substances and emitting the adsorbed substances. Because of this feature, people have cleverly given it a variety of functions, let's talk about it. some of its main functions in conjunction with orchid cultivation:
1. The function of regulating dryness and humidity of small-scale gases. When wet, charcoal absorbs moisture and when dry, it releases the absorbed moisture, doing an excellent job of regulating humidity.
2. Adjust the dryness and humidity of the pot soil. The porosity of charcoal can retain water needed by plant roots, allowing the soil to hold more water. He canbsorb part of the water from the soil when the soil moisture is high and can release the water when the soil water is high. too small.
3. Improve the air permeability and drainage of potted soil. Mixing 5-10% pea-sized charcoal into flower and tree potting soil can improve the permeability and drainage function of the soil, providing a good living space for beneficial microorganisms for plants and strengthening a healthy growing environment for plants.
4. The effect of increasing the temperature of the pot soil. After applying carbon powder to the soil, the black carbon particles absorb solar thermal energy, which can increase the temperature of the soil and promote early germination of seeds
5, a to improve the soil. After applying carbon powder to the soil, rhizobia can be generated on the surface of the carbon due toof carbon adsorption capacity, thus forming a suitable substrate.Soil for growing plants.
6. There is a public opinion that charcoal powder can improve the growth, color and taste of grains, beans and vegetables. If this function is true, can it improve the growth and color of Clivia? This remains to be scientifically demonstrated.
7. Carbon powder can also be used as a slow release agent for pesticides and fertilizers to maintain a balanced state of pesticides and organic fertilizers. This balance can be used to slowly release pesticides or fertilizers over a long period of time. time and not easily lost with rainwater.
8. Carbon powder can also change soil pH, increase soil carbon dioxide content, absorb harmful soil toxins, and increase the activity of soil microorganisms.
9. It can improve the plant's strong ability to resist pests and diseases.
Activated carbon is mainly used to absorb harmful gases and substances in our lives, especially in home decoration. Zhang Gong, senior engineer of Shijiazhuang Better Environmental Protection Engineering Co., Ltd., a designated formaldehyde removal enterprise in Shijiazhuang, said: There are many brands of activated carbon on the market, but the quality is uneven, and many of them are ordinary carbon masquerading as activated carbon. So, how to identify and select activated carbon? Let's look together.
1. Look at the density. The more pores the activated carbon has, the higher the adsorption performance, the looser the activated carbon, the lower the relative density, the lighter the feeling and the smaller the volume. in large equal weight packaging. It is recommendedto buy activated carbon products of low density, light to the touch and large volume of equal weight.
2. Look at the size. The smaller the activated carbon particles, the larger the contact area with air, the larger the specific surface area, and the better the adsorption performance. the greater the losses and dust during the crushing and production process. Therefore, in order to reduce costs, many manufacturers use large particle activated carbon. with a particle size of about 0.5mm, it not only achieves the best performance, but also ensures that it is not powder and there is no pollution. It is recommended to choose activated carbon products with particle diameters between 0.42 and 0.85 mm.
3. Look at the components. Activated carbon absorbs harmful gases depending on pore size. Different harmful gaseshave different molecular weights and different particle sizes. Activated carbon gaps should be between 0.45 and 2 nanometers. formaldehyde and other toxic gases. Gas, internationally, coconut shell carbon is the first choice activated carbon for absorbing odor, benzene and other pollution, and gas-phase spherical microporous activated carbon is the adsorption carbon of formaldehyde the most ideal. It is recommended to purchase a complete adsorption product mixed with coconut shell activated carbon and gas-phase spherical microporous activated carbon. Coconut shell is not necessarily the best, it must match the pore size of the harmful gas molecules.
4. Look at the dust. In the process of producing activated carbon, the crushed raw materials must be processed to remove dust, otherwise there will be too much dust andpoor cleanliness, which will lead to pollution. the human body and objects. The inferior activated carbon on the market is To reduce costs, there is no post-treatment and the dust is very large. Dark colored packaging bags are often used. and they will stain items and cause secondary pollution when used. suggestionChoose a small charcoal bag, which is a breathable white non-woven bag, dust-free and dirty to the touch.
5. Look at the bubbles. Put a small handful of activated charcoal in the water. Since water molecules are small, water will gradually immerse into the pore structure of the activated carbon, forcing air in. The pores will be evacuated, producing a series of extremely fine bubbles. A small line of bubbles will be drawn from the water, and at the same time it will make a slight bubble sound. The better the performance of activated carbon. ,pThis phenomenon will be serious. The longer it lasts.
6. Look at the charred material. Carbonized material is carbon that has only undergone the carbonization process without the activation process. It is not true activated carbon. The activation process is the most important creation process. a porous structure in the process of manufacturing activated carbon. The material carbonized in the process has almost no adsorption properties. Since the carbonized material does not undergo the process of activation and creation of pores, the surface is smoother than activated carbon and the color is whitish with a slight metallic sheen. It is harder than activated carbon and is much heavier.
7. Look at the brand. There are many brands of activated charcoal on the general market, many of which are low quality and of varying quality. When purchasing, we must choose activated carbon produced by manufacturerss certified by the state, endowed with a certain strength and brand awareness. For example, check whether there are any honorary qualifications issued by authoritative national organizations. Of course, many other so-called honorary certificates can be purchased for tens of thousands of yuan, but generally speaking, provincial or national famous brands must have strong enough overall strength to win. them. . Second, the brand must be a registered trademark for more than 3 years. As for choosing the brand of activated carbon, it is recommended to choose products manufactured by professional activated carbon manufacturers. Warm reminder: Activated carbon should be dried outdoors after being used for a period of time. The purpose of drying is to release the internal space occupied by moisture through exposure to sunlight in order to better absorb harmful gases. It is recommended to expose it to the sun fort 3 to 5 hours approximately every 15 days.
