How to fertilize plant ash Is it good to fertilize orchids with plant ash?

1) Pads. The bottom of the pot is covered with a piece of tile to cover the drainage hole, and then gradually filled with bricks, tiles or shells, in which the large gap is filled with mud particles or bean stones, generally about 1 2-1 3 of the height of the pot. The net height of the upper remainder is about 10-15 cm, which is reserved for the cultivation soil.

The specific height should be determined according to the species of orchid, the length of the orchid root and the height of the pot.

2) Planting. On the bedding layer, first fill in 2-3 cm of culture soil, slightly compacted by hand, you can put the orchid upright on it, according to the size of the plant and the pot, you can plant several single plants, 2 clusters, 3 clusters or more clusters in a pot. 3. The bush should be planted into a full momentum.

4 bushes can be planted into a square, and 5 bushes should be arranged into a plum blossom shape.

3) Fill the soil. When planting, hold the leaves with one hand, add nutrient soil with the other, and hold the base of the orchid plant slightly upwards to stretch the root system and shake the orchid pot at the same time. Let the cultivated soil penetrate deep into the rhizosphere; Continue to add soil and shake the pot to adjust the position and height of the plant.

Press along the edge of the pot with your hands, but do not hurt the roots too much, continue to add soil and squeeze until the soil on the surface of the pot is 2-3 cm higher than the mouth of the pot, slightly steamed bread shaped.

4) Paving. After planting, you can spread a layer of small stones or moss on the surface of the potting soil, preferably high-quality moss under the forest, which is not only beautiful, but also can regulate the water, and can also protect the leaf surface from being polluted by muddy water, and the new shoots will not be infected with the germs in the soil and rot their hearts; In addition, it can also slow down the erosion of the potting soil by rainwater and keep the potting soil loose.

5) Watering. After the planting is completed, the first water must be watered, the potting soil must be soaked, the water droplets should be small, and the impulse should not be large. If it is placed in a basin of water, do not soak it for too long. Once the potting soil is soaked, the pots are immediately removed and then placed in a shaded place for maintenance.

6) Fertilization. You can use "Yanwo microbial agent" + "root rooting agent" in the early stage, and the effect will be better when combined with Yanwo water-soluble fertilizer.

Grass ash is alkaline and belongs to the fast-acting potassium fertilizer. Orchids, prefer slightly acidic soils, are not tolerant to fertilizers; It is best not to apply it alone, or in small amounts with other fertilizers.

General plant ash, mainly used as base fertilizer, seed fertilizer and top dressing; Its aqueous solution can also be used for extra-root top dressing. When applied, strip application and acupoint application can be used. depth 8 10 cm, after applying the soil.

Mix 2 3 times the wet soil before application, or spray it with a little water before using it to prevent ash from flying. Grass ash is mainly suitable for potassium-deficient soil, which can give full play to the fertilizer effect of plant ash; or on potassium-loving crops such as potatoes, sweet potatoes, cotton and leguminous crops.

1. Every winter and the spring of the following year, go to the mountains to cut some grass, small leaves and miscellaneous trees, mango poles, reed poles, etc., dry and burn them into ashes. After cooling, it is directly put on the surface of the orchid pot, with a thickness of about two to three centimeters, and the management is the same as normal, without putting other fertilizers.

2. In the second year, remove the ashes from the grass and trees on the pot surface of the first year and put new ones on them, every year. After several years of practice comparison, it is found that the orchids with grass and wood ash have green leaves, thick seedlings, thick and hard leaves, and 1-2 arrows more flowers than normal, especially orchids with less anthracnose. The orchid uses plant ash, and the effect is obvious.

3. The main element in plant ash is potassium, which is one of the three major elements required for plant growth. Many experienced flower friends have used plant ash to cultivate orchids, and they have received good results.

1. Vegetation ash accumulation method: grass and wood ash matter is light and alkaline, easy to go with the wind when dry, easy to go with water when wet, and easy to cause nitrogen volatilization loss in 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 possible, the plant ash should be packed in a plastic bag in a timely manner and sealed for preservation.

2. Separate storage should be strictly avoided mixed with other farm fertilizers. 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 not cause fertilizer waste, but also reduce environmental pollution.

3. Application: Grass ash cannot be mixed with organic farm fertilizer (human manure, manure, compost fertilizer, etc.) and ammonium nitrogen fertilizer, so as not to cause 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. Because the grass ash is alkaline, it is advisable to apply cohesive soil, acidic or neutral soil.

Soil application can be used as basal fertilizer, seed fertilizer and top dressing, and can also be used as a mulch for seedlings and seedlings (cover seed fertilizer).

4. When making base fertilizer and seed fertilizer, the amount of fertilizer should not be too large and should be isolated from the seeds to prevent seed burning. The dosage per mu is generally 50-100 kg. Soil application should be concentrated application, using strip application and hole application, depth of 8-10 cm, covering soil after application.

Mix 2-3 times of wet soil or spray wet with a little water before application.

5. Top dressing outside the roots; The potassium contained in plant ash is more than 90% soluble in water, which is a fast-acting potassium fertilizer. According to this characteristic, plant ash can be used as extra-root top dressing, that is, foliar spraying with a concentration of 1% plant ash leachate.

6. Priority crops. Grass ash is suitable for all kinds of crops, especially for potassium-loving or potassium-loving chlorine crops, such as potatoes, sweet potatoes, tobacco, grapes, sunflowers, sugar beets, etc. Grass ash is used in potatoes, not only for soil application, but also for coating potato tuber wounds, which can be used as seed fertilizer and prevent wound infection and rot.

7. Fertilizer effect of plant ash: potassium can promote nitrogen metabolism and the synthesis and transportation of sugars in plants, which can promote the growth of plants, enhance their ability to resist diseases, insects and natural disasters, and also have the effect of improving plant drought resistance. Guarantee the smooth progress of various metabolic processes.

When lacking, the stalks are weak and prone to lodging.

1. Grass ash cannot be directly fertilized, and must be fully decomposed before it can be used as fertilizer, otherwise it will burn roots and seedlings and affect crop growth. Funny.

2. Grass ash can be used as fertilizer, because plant ash is the ash after plant burning, so almost all the mineral elements contained in plants are contained in plant ash. Among them, the most abundant is potassium, the main component of plant ash is potassium carbonate (KCO), generally containing 6 12% potassium, of which more than 90% is water-soluble, 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.

1. What kind of fertilizer is plant ash: plant ash can be used as fertilizer, and it is also a relatively common farm fertilizer, which can play a role in sterilization and prevention of pests and diseases after use. It is also an organic fertilizer, which is suitable for acidic soils or clay soils, and can be used as a mulch for seedlings.

Because it contains more potassium, it is also a potash fertilizer. It is an alkaline fertilizer and should not be used with acidic fertilizers and farmyard fertilizers. If you want to spray the leaves, you need to filter them before you can use them, so that they do not pollute the leaves and flowers of the plants.

2. How to use plant ash: It can be used as topdressing outside the roots, or it can be sprayed with a liquid with a lower concentration. It is great for use in potassium-loving plants, such as:

Sunflowers, potatoes, grapes, etc. Do not mix it with phosphate fertilizer when using, it is easy to have low fertilizer efficiency.

1. Cooperate with other organic fertilizers as base fertilizer for flower raising: When planting flowers, 10% 20% plant ash can be mixed with other organic fertilizers and filled into the bottom of the pot for flower base fertilizer. It can loosen the soil, increase the nutrients of organic fertilizer, and can have the effect of sterilization and insect control, and can also promote root growth and reduce the probability of pests and diseases.

2. Grass and wood ash mixed with flower seeds: when sowing and propagating flowers, sprinkle an appropriate amount of plant ash on them after soaking the flower seeds and mix them evenly before sowing, which can play a role in protecting the root system of seed buds and flower seedlings, prevent pests in the soil from eating flower seeds, and at the same time prevent various diseases of flower seedlings and effectively guarantee the emergence rate of flowers.

3. Flower root transplanting and disinfection treatment: when transplanting flowers, it is inevitable to dig up the root system of flowers, if there is no sterilization and disinfection treatment for the injured roots when transplanting, it is easy to infect bacteria from the injured parts of the root system, resulting in flower diseases. In order to improve the survival rate of flower transplanting, a layer of plant ash can be sprinkled on the roots of flowers during transplanting, which can have the effect of sterilization and disinfection on the root system, and can also promote the growth of the root system and reduce the occurrence of pests and diseases.

In addition, you can also use 20% 30% plant ash solution to soak the roots of flowers for 2 to 3 hours, and then plant them in pots, which will also have a good effect.

4. Foliar fertilization of flowers: It is directly used as foliar fertilizer for flowers. Before and after the flowering of flowers, 50% 60% concentration of leaching solution can be made with plant ash, and the clear water liquid can be filtered out after precipitation, and the leaf surface of flowers can be sprayed with the precipitated plant ash immersion, which can make the flowers absorb the nutrients in the plant ash faster and be utilized, which can make the flowers grow lush and more vigorous.
