Why plant ash can prevent insects such as snakes and crabs?

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. There is a smell of smoke in the plant ash, and the plant ash does not have what the pest needs, so the pest always stays away.

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. Therefore, the following methods should be taken to accumulate plant ash:

Farmers who have the conditions to store the ash should build a permanent ash warehouse for plants and trees, and pour the ash into the warehouse every day for accumulation. The ash silo should have a canopy, the ground should be high (to avoid water accumulation), hardened, and moisture-proof.

If the bag is conditional, the plant ash should be packed in a plastic bag in time and sealed for preservation.

Single storage should be strictly avoided mixed with other farm manure. Some farmers are accustomed to pouring plant ash into puddles and mixing it with organic manure and straw, while others put plant ash in toilets or mixing it with human manure and manure. It is very wrong to do so.

Because the plant ash is alkaline, the result of the above method will cause the volatilization of nitrogen in organic fertilizer and reduce the fertilizer efficiency. Treating plant ash in this way will not only cause waste of fertilizer, but also cause environmental pollution.

The main component of plant ash is potassium carbonate (K2CO3) with a relative molecular weight of 138. 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. Among them, the most abundant is potassium, which generally contains 6 12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate; followed by phosphorus, which generally contains; It also contains calcium, magnesium, silicon, sulfur and micronutrients such as iron, manganese, copper, zinc, boron, molybdenum, etc.

The nutrient content of ash of different plants is different, and the potassium content of sunflower straw is the highest (see table for details). When the same amount of potassium was applied to plant ash, the fertilizer efficiency was better than that of chemical potassium fertilizer. Therefore, it is a kind of inorganic farm fertilizer with wide range, low cost, complete nutrients and obvious fertilizer efficiency.

Its main component is potassium carbonate, which is rich in phosphorus, potassium, calcium, magnesium, iron and other elements, and is a natural fast-acting potassium fertilizer. It can promote the photosynthesis of plants and improve the quality of crops. Because its main ingredient is potassium carbonate, it is an alkaline fertilizer, which can also neutralize acidic soil to a certain extent, and has a fungicidal effect on the root system of plants.

But in some alkaline soils are not suitable for plant ash. Grass ash can also be used as an insecticide after filtering with water, and has a good killing effect on red spiders and aphids.

The above is what you know, I don't know if you have any other understanding of plant ash. I often encountered such a problem in high school chemistry, when I listened to the teacher talk about plant ash, I only knew that it could improve acidic soil, but I didn't know that it was so useful. Seeing this, I believe that you must have a deep understanding of plant ash.

If you live in the countryside, you can try to use plant ash as fertilizer yourself. The vegetables grown in this way are really natural and pollution-free!

Do you know what the ashes do? Let me know what you think!

Grass ash is a kind of farmhouse fertilizer, can control pests and diseases, it contains other components are actually phosphorus, nitrogen, potassium, in fact, it can help the growth of plants play a good role.

The main component of plant ash is potassium carbonate, which is an alkaline farmhouse fertilizer, and should not be mixed with ammonium nitrogen fertilizer when using pest control, because the mixed use of the two will reduce the fertilizer efficiency.

The main ingredient is potassium carbonate, there is also a small amount of nitrate, it is a natural farmhouse potash fertilizer, put the plant ash into the clean water filter, take the filtered liquid, add an appropriate amount of nitric acid, it becomes a potassium nitrate solution.

Point 1 contains a special nutrient that can kill the whole bug, point 2 has nitrogen in it, such an ingredient can kill the bug, and point 3 there is an ingredient like phosphorus that can kill the bug.

I think it's probably because of the plant ash, which has a lot of functions and can be used to do a lot of things.

That's because plant ash can be used to make many things in the countryside, so it is said by farmers.

Because plant ash has many ways to use and function in rural areas, it is called all-purpose ash.

Because the plant ash has a good sterilization and disinfection effect, in the eyes of farmers, this thing is a miracle medicine in the pigsty.

Plant ash is a good potassium fertilizer, the main component is potassium carbonate, and some are potassium sulfate and potassium chloride. Among them, potassium fertilizers are water-soluble, and phosphorus is weakly acid-soluble. Because the aqueous solution of plant ash is alkaline, it is more suitable for application on acidic soils in the south.

It is especially suitable for application on acidic sandy loam or sandy soils in the south.

Prevention and control of rust and fruit disease For the apple trees that have been diseased, dig a ring ditch with a width of 50 cm and a depth of 60 cm at a distance of about 50 cm from the root, and then apply the plant ash as base fertilizer into the ditch, water enough, and press the new soil that has been moved.

Prevention and control of root rot Grass ash has a good effect on the prevention and control of root rot of fruit trees such as pear, peach, hawthorn. The method is to first pick up the soil at the root of the fruit tree, remove the soil around the rotten root, scrape off the bark of the diseased root, dry it for 24 hours, cover each plant with fresh plant ash kilograms, and then cover the soil, the rate can reach 90%.

Prevention and control of powdery mildew For fruit trees with powdery mildew, dig a ring ditch 10 20 cm deep at a distance of 15 cm from the plant, apply 10 20 kg of plant ash in the ditch, and cover it with a layer of thin soil, with a rate of up to 80%.

Control of aphids Use 10 kg of plant ash to 50 kg of water, soak for 48 hours to filter, take filtrate and spray, which can effectively control aphids on fruit trees.

Prevention and control of early defoliation disease with 8 kg of plant ash to 100 kg of water, soaked for 48 hours of filtration, the filtrate and fungicide mixed spray, has a certain prevention and control effect on early apple defoliation, the effect is better than a single spray fungicide.

The prevention and control of blight, anthracnose, and the sprinkling of grass and wood ash along the ridge at the seedling stage of diseased trees, with a dosage of 30 50 kg per mu, can effectively prevent the occurrence of these two diseases.

It should be noted that when applying plant ash on the foliar surface, be sure to use the filtrate after soaking to prevent contamination of the leaves. Grass ash is an alkaline substance and cannot be used in saline-alkali land.

Inhibit pests and diseases.

Sprinkle 30 50 kg of plant ash per mu nursery, which can kill underground insects and bacteria, protect seeds, roots and stems, reduce pests and diseases, and prevent the occurrence of blight and anthracnose. The application of plant ash in the orchard can control the occurrence of powdery mildew and fruit rust, and the application of grass ash kilograms per plant also has the effect of preventing and controlling root rot. Spraying 2 -3 plant ash leaching solution can control aphids, red spiders and other pests on flowers and fruits, and improve the drug control effect of pear psyllid.

My ** store sells water disinfectant, put the water from the field into a container, and then put in a disinfectant tablet, you can drink it after a while, and there are many individual self-heating food, which are essential rations in the field or emergency situations
