Why do farmers burn grass ashes and scatter them on the grass? What is the purpose of this?

If you go to the vegetable fields in the countryside, you will find that many farmers will ash some plants and trees in their homes when they grow vegetables.

Left to stay, and sprinkled on the vegetables, these plant ashes are like a farmer's treasure. Grass ash does have a lot of uses, and these are herbaceous plants.

Ashes left behind after combustion, and insoluble substances. Plant ash is very light and alkaline, so it is easy to be blown away by the wind when it is dry, and it is very easy to flow with water when it is wet. These plant ashes are sprinkled on the grass to allow the seeds to germinate faster, to allow the seeds to take root faster, to increase the yield of plants, and to prevent pests and diseases.

Generally, farmers will put some plant ash on the small leaves when planting vegetables, which can increase the temperature of the soil, and can also keep the vegetables in a ventilated state, so that the seeds can germinate faster, and these seedlings will grow very neatly and strongly. In addition, sprinkling plant ash on the newly planted seeds can also make the seeds take root faster. <>

Many people usually like to plant flowers and plants and some green plants at home, but some newly planted flowers and plants are very easy to lose leaves. At this time, you can find some fresh plant ash, and then put in some water to stir, quietly put it for about 16 hours, and then filter, remove these slag residues and put them in the watering can to spray these plants as nutrients, and you can obviously see that the vitality of these leaves has increased. Strawberry-flavored water prevents plants from losing their leaves and also enhances photosynthesis in plants.

So the quality of the plants will also be greatly improved. <>

When farmers in rural areas grow vegetables, the most common method is to use plant ash to drive away pests and diseases, especially cucumbers, which are very easy to grow insects on the leaves when they are planted at home. At the seedling stage, it is susceptible to fireflies.

At this time, sprinkle some plant ash, which can effectively isolate pests and diseases. Plant ash is an alkaline substance and is not suitable for mixing with acidic fertilizers or pesticides.

In this way, fertilization can be applied and disinfection can be carried out. The purpose is to sterilize and disinfect the grassland in this way, and to prevent some insect pests, bacterial infection and pollution, to prevent disasters, and to prevent soil from being poor.

Grass ash can add rich potassium to the land, which can prevent crops from having diseases and insects, and can play a good role in moisturizing.

In this way, the vegetation can be better incinerated, and it is a high-quality pesticide fertilizer, which can prevent the appearance of underground pests.

1. Grass ash should not be sprinkled directly on the ground, because it will corrode the rotten leaves of plants.

2. Grass ash can be used as base fertilizer, seed fertilizer or top dressing, or used as a mulch for seedlings.

3. The main component of plant ash is potassium, all of which generally will not cause seedling burning, but it is still necessary to layer the soil when using, if the plant ash makes the old leakage properly can promote the germination of plants. Included.

Grass ash cannot be sprinkled directly into the ground.

Grass ash should not be sprinkled directly on the ground, because plant ash is an alkaline substance, and direct sprinkling will corrode the leaf surface of the plant for chain stool collapse. Grass ash can be used as base fertilizer, seed fertilizer or top dressing, can also be used as a mulch for seedlings, in the base fertilizer, seed fertilizer must pay attention to control the amount.

Grass ash introduction

Grass ash refers to the residues of plants (herbaceous and woody) after they have been burned. It is an insoluble substance. 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, which is easy to go away with the wind when dry, easy to go with water when wet, and easy to cause volatilization loss of nitrogen element in contact with nitrogen fertilizer.

The earthen stoves of rural families burn firewood and grass, and the grass and wood ash produced should be collected at any time according to the above methods. Straw that cannot be brought back in the field is mostly burned on the spot. Attention should be paid to concentrated burning, and the ashes of plants and trees should be recovered and returned to the field.

Some power plants use straw and the like as raw materials for power generation. A large amount of plant ash produced after combustion can be returned to the field as a high-quality potassium fertilizer.

Grass ash** is the residue of burning plants. 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.

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.

Grass ash should not be sprinkled directly on the ground, because plant ash is an alkaline substance, and direct sprinkling will have a corrosive effect on the leaf surface of plants.

Grass ash can be used as base fertilizer, seed fertilizer or top dressing, can also be used as a mulch for seedlings, in the base fertilizer, seed fertilizer must pay attention to control the amount. Generally, about 50-100 kg per mu is used, but the specific amount is still determined according to the crop, and the plant ash can be sprayed with 2-3 times the wet soil or a small amount of water before use.

Since the main component of plant ash is potassium, it generally does not cause seedling burning, but it is still necessary to insulate the soil when it is used. Because the plant ash contains potassium oxide, which is a fast-acting fertilizer component that is easily soluble in water, and potassium oxide produces potassium hydroxide when exposed to water, which is strongly alkaline, so do not use it too close to the root.

Grass ash, if used properly, can be a good way to promote germination. For example, after sowing flowers and trees, cover 1-2 cm with plant ash, or sprinkle in the morning and evening when there is no wind, which can effectively increase the soil temperature, keep the soil loose, and make the seeds germinate 7-10 days earlier.

1. When planting flowers, 10%-20% of plant ash and other organic fertilizers can be mixed evenly and filled into the bottom of the pot, which can be used as base fertilizer; Or when sowing and propagating flowers, sprinkle an appropriate amount of plant ash on top of the flower seeds after soaking them, which can improve the germination rate of seeds.

2. When planting potatoes, you can mix potatoes with plant ash, which can prevent water seepage. Because potatoes are cut into several bud points when they are sown, the use of plant ash can prevent flow injuries, and can also achieve disinfection and sterilization to prevent bacterial flow injuries.

3. Since the plant ash cannot be sprinkled directly, it can be mixed with water and soaked for 24 hours before filtering and spraying, but it should be noted that the spraying is the filtered clarifier, so as to ensure that the leaves will not be polluted.

Summary. Hello, plant ash is a natural fertilizer containing potassium and carbonates that can promote plant growth. But plant ash is not a fertilizer that can be sprinkled directly on the ground.

Hello, plant ash is a natural fertilizer containing potassium and carbonate that can promote plant growth. But hail Zheng Bei is plant ash, not fertilizer that can be sprinkled directly on the ground after the clump chain.

To use plant ash, it is necessary to apply reasonable fertilization according to soil conditions and crop requirements. Generally speaking, for crops that are easy to produce branches and change to acidic soils, such as tomatoes and potatoes, plant ash can be used to neutralize soil acidity.

For crops with high demand for potassium yuanfan, such as sugar beets, root vegetables, fruit trees, etc., an appropriate amount of plant ash can be used to provide potassium for them to promote the growth of stool stools. At the same time, it is also necessary to pay attention to the amount of plant ash used, excessive use will lead to alkalinization of the soil, from the chain cavity brigade and affect the growth of plants.

Care should also be taken to avoid sprinkling excessive plant ash directly on the roots or leaves of the plant, as this can cause injury to the plant.

The best way to do this is to mix the plant ash into the soil surface or irrigation water when spreading or watering, and let it slowly balance and release it in the soil to achieve the best fertilization effect.

1. Rental plant ash should not be sprinkled directly on the ground, because it will corrode the leaves of plants.

2. Grass ash can be used as base fertilizer, seed fertilizer or top dressing, or as a mulch for seedlings, and must pay attention to controlling the amount of fertilizer when making base fertilizer and seed fertilizer.

3. The main disadvantage of plant ash is potassium, which generally does not cause seedlings to burn, but it is still necessary to separate soil when using, and if the plant ash is used properly, it can promote plant germination.
