What are the benefits of spraying plant ash with water on crops? How should it be sprayed?

Plant ash. It is a common item in the countryside, which family does not burn firewood and grass? In some areas, it is forbidden to burn firewood and grass, but I have not heard of it here, and in winter, it is all about burning kang with corn stalks and cutting the branches of fruit trees. The embers left over from the fire are plant ash, also known as small ash.

Most are used as fertilizers.

Wood ash contains potassium, calcium, phosphorus, magnesium, sulfur, sodium and other elements, and the amount of components contained in the embers after ignition is different from different raw materials, which is also related to the level of incineration. But in general, plant ash contains more potassium, mainly ammonium bicarbonate.

This is followed by ammonium sulfate.

Very little chlorine than potassium, all water-soluble.

of potassium; Then there is phosphorus and so on. Grass ash contains a lot of trace elements.

Therefore, it is called high-quality organic fertilizer. Because plant ash contains more potassium, it is also called high-quality potassium fertilizer. Grass ash can be used as base fertilizer, fertilization and leaf fertilizer.

Mix the plant ash with appropriate water, and after depositing it statically, take its solution too carefully, which is a water-soluble fertilizer, which can be sprayed on the leaves. Grass ash liquid plus moderate water spraying, because it contains a variety of potassium, phosphorus, calcium, magnesium and other large, medium and nutrient elements, can be digested and absorbed by crop leaves, stems and fruits, promote the growth and development of crops, make them thick, green, fruit, improve efficiency.

Most bacteria in nature prefer to grow and develop in acidic conditions, but the ash water of plants and trees is alkaline, and when sprayed on the foliage of crops, it changes the natural environment in which pathogenic bacteria survive.

It has been inhibited from growing, so it has the effect of sterilization and disinfection. For example, downy mildew, rust, etc. of crops, spraying grass and wood ash water will obtain certain control. For example, everyone here will soak 3 catties of plant ash in 6 catties of water, soak it overnight and then think about the gray water, and spray shallots with 2 buckets of water.

Small seedlings, sprayed once every 7 days, after spraying 2-3 times, the growth and development of onion seedlings is good, the production of pests and diseases is less, and the ability to resist disease damage and lodging are significantly enhanced.

Grass and tree gray water has a certain destructive effect on leaf pests such as cotton aphids and planthoppers, and the key is also due to alkaline. Like before, we used plant ash to get rid of insects, and when the dew was not dry, we sprinkled grass ash on the bean leaves to destroy the bean insects.

and other insect pests. <>

If you soak 10 catties of plant ash in 50 catties of water, soak it overnight, and spray it on the human body of raw cotton aphid or planthopper after consideration, which has excellent actual effect of insect removal, and also has the effect of applying potassium fertilizer to improve the resistance of plants to lodging.

All in all, plant ash water can supplement vitamins, is a good leaf fertilizer, and can have the effect of insecticide, sterilization and disinfection. But after all, plant ash is a alkaline fertilizer, so it cannot be mixed with acidic chemicals; In addition, the ash water contains calcium, and it is not necessary to mix it with phosphorus and potassium fertilizers containing organic matter, so as to prevent reducing the effectiveness of phosphorus and potassium fertilizers, it is best to spray alone.

It helps to fertilize crops, absorb some nutrients from plant ash, and also help prevent insect infestations; When spraying fertilizer, you must be careful not to apply more fertilizer to avoid overnutrition.

Grass ash is a common thing in the countryside, who doesn't burn firewood and grass? In some places, it is said that it is not allowed to burn firewood and grass, but I have not heard of it here, and in winter it is burned with corn stalks and pruning the branches of fruit trees. The ashes left over from the fire are plant ashes, also called small ashes, and most of them are used as fertilizer.

Grass ash contains potassium, calcium, phosphorus, magnesium, sulfur, sodium and other elements, and the amount of components contained in the ash after burning different raw materials is different, which is also related to the degree of combustion. But all in all, plant ash contains the most potassium, mainly potassium carbonate, followed by potassium sulfate, and very little chlorine than potassium, all of which are water-soluble potassium; Then there is phosphorus, etc.

Grass ash is known as a high-quality organic fertilizer because it contains a lot of nutrients. And because plant ash contains the most potassium, it is also called high-quality potassium fertilizer. Grass ash can be used as base fertilizer, top dressing and foliar fertilizer.

Mix the plant ash with an appropriate amount of water, and after static precipitation, filter its aqueous solution, which is water-soluble fertilizer, which can be sprayed on the foliar surface.

Grass ash liquid is sprayed with an appropriate amount of water, because it is rich in potassium, phosphorus, calcium, magnesium and other large, medium and trace elements, which can be absorbed by crop stems, leaves and fruits, promote the growth of crop stems and leaves, make them thick, green, good fruit quality, and improve yield.

In short, plant ash water can supplement nutrients, is a very good foliar fertilizer, and can play a role in insecticide and sterilization. But after all, plant ash is an alkaline fertilizer, so it cannot be mixed with acidic substances; In addition, the ash water contains calcium, and it should not be mixed with inorganic phosphate fertilizer, so as not to reduce the effectiveness of phosphate fertilizer, and it is best to spray it alone.

Grass ash is a kind of fertilizer, because it contains a certain amount of potassium, calcium and other nutrients and elements, so it can play a role in promoting plant growth. Generally speaking, it is best not to apply plant ash directly with water, but to mix with the soil before application, so as to avoid the loss of nutrients in it with water and give the best fertilizer effect. Specifically, plant ash can be mixed with the soil before being applied to the root system of the plant, or the plant ash can be sprinkled on the surface of the plant and then covered with the soil to slow down the release of nutrients in it so that it can better provide nutrients to the plant.

In addition, plant ash can also be used to treat problems such as soil acidification, which can improve the pH value of the soil and improve the soil texture. However, it should be noted that excessive use of plant ash may be detrimental to plant growth, so it is necessary to pay attention to the appropriate amount when using it to avoid affecting the environment and plant health.

Question: What pesticides can be mixed with plant ash?

Answer: Grass ash is a solid powder, which contains charcoal particles, wood residue, dust and other impurities. Grass ash is a kind of potassium fertilizer with a very high potassium content in farmhouse fertilizer, with a potassium content of 5 8%, of which more than 90% is water-soluble substance, which exists in the form of potassium carbonate in plant ash.

It also contains phosphate fertilizers, which are soluble phosphorus-containing compounds. Grass ash is an alkaline substance and cannot be mixed with acidic substances, such as ammonium nitrogen fertilizer, decomposed human and animal manure, acidic pesticides and other acidic substances.

Pesticides are generally sprayed with aqueous solution as the main method of use, and dust is rarely used. Because the use of dust will pollute the atmospheric environment, it is not environmentally friendly. Acidic pesticides include dimethoate, dimethoate, ethephon, methyl parathion, malathion, carbaryl and other acidic pesticides, which cannot be mixed with plant ash leach.

Otherwise, it will reduce the fertilizer efficiency and pesticide effect.

In short, plant ash is an alkaline substance, whether it is used in dry matter or in the form of leaching solution, it cannot be mixed with acidic pesticides and chemical fertilizers to avoid reducing the efficacy and fertilizer effect, resulting in the waste of plant ash, pesticides and fertilizers. Be careful when using it.

Thank you: Grass ash, high-quality farmhouse potash.

It's a pity that for the sake of environmental protection, no smoke is allowed now. Therefore, the farmer has no plant ash. At all, there is no need to worry about the application problem.

Grass ash, weak alkaline fertilizer.

Do not be associated with acidic and slightly acidic fertilizers.

Boric acid, which is often sprayed, is alkaline and can be sprayed with plant ash leaching solution. Potassium supplementation and boron supplementation, Bordeaux liquid, and stone sulfur mixture are alkaline, but they cannot be applied together.

Commonly used, most of them are acidic or slightly acidic, and they should not be mixed with them. Thank you!
