It is said that plant ash is very good, what is the use of plant ash?

Grass ash is a kind of fertilizer that we farmers are very familiar with, in addition to being used as fertilizer, it also has a certain bactericidal and insecticidal effect, but we should pay attention to the fact that some people deify the plant ash too much, this is not necessary, we must have a correct understanding of plant ash.

First of all, plant ash can be used as fertilizer, plant ash is produced by some plants after burning, many nutrients in these plants are left in the plant ash, which is more potassium element, according to some information, the potassium content in plant ash can reach about 6% 12%.

In addition, there will be some phosphorus and other trace elements in the plant ash, which can be said to contain more comprehensive nutrients.

The potassium element in plant ash is mainly potassium carbonate, which is more soluble in water, including some other nutrients, and is the same. The better the water solubility, the easier it is to be absorbed, so the effect of plant ash is relatively good when used as fertilizer.

We can think of plant ash as a potassium fertilizer containing a certain amount of medium and trace elements, which can be used for potassium-loving crops or when the crop needs more potassium.

Grass ash can also be used as a fungicide, and plant ash has a certain bactericidal effect, which can be used in the prevention and control of diseases of some crops. For example, when controlling fruit tree root rot, you can pick up the soil around the root system of fruit trees, fill it with plant ash and then cover the soil, the effect is very good.

Then we plant leeks in the countryside, after cutting the leeks, sprinkle some plant ash, so that the leeks will grow better, that is, the use of plant ash is both fertilizer and sterilization.

And when we plant potatoes, we will mix potato wedges with plant ash, which is also the effect of using plant ash as fertilizer and sterilization.

Grass ash has a certain insecticidal effect in the control of some pests, we can spray some plant ash leaching solution, there will also be a certain effect, such as some aphids, when the number of occurrences is not very large, we can spray some plant ash leaching solution, there will be a certain effect.

To correctly understand the plant ash, the grass ash is indeed a good fertilizer, which is both fertilizer and can kill bacteria and insects, but it does not mean that it is so magical, we must have a correct understanding of the plant ash.

First of all, there is no organic matter in the plant ash, and the organic matter is burned when it is burned, so the plant ash is just an inorganic fertilizer, we can say that the plant ash is a kind of farm fertilizer, but we cannot say that the plant ash is organic fertilizer, and there is no organic matter in the plant ash, which has no effect on increasing the organic matter content in the soil.

In addition, the plant ash is alkaline, and most of the current pesticides and fertilizers can not be mixed, which should be paid more attention to when using.

Finally, although the plant ash has a certain bactericidal and insecticidal effect, it can not replace pesticides, especially when the pests and diseases are more serious, the plant ash only has a certain bactericidal and insecticidal effect, and the actual effect is much worse than that of pesticides, so it can not rely too much on plant ash in the prevention and control of pests and diseases.

All in all, plant ash is a good thing, but we must correctly understand and apply it reasonably in order to play an effect, and we can't be too superstitious about the role of plant ash.

The use and efficacy of plant ash.

Grass ash refers to the remnants of burning herbs and woody plants.

Grass ash refers to the residue of herbaceous and woody plants after burning, which is an insoluble substance. Grass ash fertilizer Because plant ash is the ash after plant burning, almost all the mineral elements contained in plants are contained in plant ash.

The gray matter of plants and trees is light and alkaline, which is easy to go away with the wind when dry and easy to go with water when wet, and it is easy to cause nitrogen volatilization loss when it comes into contact with nitrogen fertilizer. Try not to use plant ash with organic farm fertilizer, which is easy to reduce the fertilizer efficiency.

Grass ash is widely used in rural areas, and can be used to make disinfectants, and has a strong sterilization effect, which can be used to disinfect livestock houses or utensils. The use of plant ash is mainly as fertilizer, medicine and disinfectant.

How to use plant ash to prevent fruit tree diseases?

Peel off the soil at the root of the fruit tree, expose the root system, scrape off the diseased skin on the root with a knife, dry the roots for 2-3 hours, smear the fresh plant ash around the roots, and then cover the soil and bury the roots. After treatment, the diseased roots can be cured in 1-2 months, which can prevent the roots from rotting.

The residues of herbaceous and woody plants after combustion, called plant ash, are insoluble substances. Grass ash fertilizer is the ash after burning of plants and plants, so it is a mineral element contained in all plants, and almost all plant ash contains it. Therefore, the benefits of plant ash are very many, and it is widely used in agriculture.

Let's take a look at the specific role of plant ash.

The role of plant ash

1. Prevent wound infection. Grass ash has the effect of sterilization, flowers and trees are easy to hurt the root system when transplanting, and a layer of plant ash can be sprinkled at the root wound, which can prevent wound infection, promote the normal growth of the root system, and improve the survival rate of transplanting.

2. Prevention and control of pests and diseases. Grass ash has a control effect on pests and diseases, it can kill insects and bacteria around the root system of plants, so as to protect seeds, roots, stems, reduce the occurrence of insect pests, and can also prevent and control pests and diseases such as blight, anthracnose, powdery mildew, red spiders.

3. Grass ash promotes rooting. The use of plant ash is rich in phosphorus and potassium elements, and the use of organic fertilizer as a base fertilizer when raising flowers can not only increase the nutrients of the soil, but also directly promote the growth of the root system, and at the same time reduce the occurrence of pests and diseases.

4. Grass ash is used as foliar fertilizer. Plant ash not only contains a large number of nutrients such as phosphorus and potassium, but also contains a variety of trace elements such as iron and magnesium, which can be made into foliar fertilizer for use. Before and after the flowering of plants and flowers, spraying 50% 80% plant ash infusion on the foliar surface can promote the vigorous branches and leaves of plants, improve photosynthesis, promote flowering, prolong the ornamental period, and improve the quality of fruits.

Wood ash is the remnants of burning plants (herbaceous and woody) after combustion. Grass ash is generally produced by burning firewood and grass in the earthen stoves of rural households, burning straw that cannot be transported back for use in the field, and burning straw as a raw material for power generation in power plants.

Grass ash is an insoluble substance, the main component is potassium carbonate, and the relative molecular weight is 138

All the mineral elements contained in plants are almost all contained in the plant ash, the plant ash is light and alkaline, and it is easy to go away with the wind when it is dry, and it is easy to go away with the water when it is wet.

The main use of plant ash is as fertilizer, medicine, and disinfectant.

01 Plant ash is the residue of burning plants. Grass ash fertilizer is the ash of plants after burning, so it is the mineral element contained in all plants, and almost all plant ash contains it. The gray matter of plants and trees is light and alkaline, and it is easy to go away with the wind when it is dry and easy to go with the water when it is wet.

02 Some power plants use straw as a raw material for power generation. A large amount of plant ash produced after combustion can be returned to the field as a high-quality potassium fertilizer. It can be made into a bagged commercial plant ash fertilizer. After adding other ingredients, it can also be made into plant ash fertilizer with a variety of uses.

03 Grass ash should not be mixed with organic farm fertilizer (human manure, manure, compost manure, etc.) and ammonium nitrogen fertilizer to avoid nitrogen volatilization loss; It should also not be mixed with phosphate fertilizer, so as not to cause phosphorus fixation and reduce the fertilizer efficiency of phosphate fertilizer.

04 Grass ash is a widely used disinfectant raw material in rural areas, which has a strong effect of killing pathogenic bacteria and viruses, and its effect is similar to that of caustic soda, a commonly used strong disinfectant. The method is: use kilograms of plant ash and 10 kilograms of heated water to be used for disinfection of livestock houses, feeding troughs, utensils, etc.
