Absolutely! There is so much use of grass ash!

The ash is a ash fertilizer made from firewood, and it is a kind of loose quick-acting fertilizer. The main ingredient is potassium carbonate. The plant ash fertilizer is the ash of the plant after burning, so the mineral elements contained in the plant are almost all contained in the ash.

The most abundant content is potassium, which generally contains 6-12% of potassium, of which more than 90% is water-soluble and exists in the form of carbonate; secondly, phosphorus, generally containing 1.5-3%; also contains calcium, magnesium, silicon, Sulfur and trace nutrients such as iron, manganese, copper, zinc, boron and molybdenum.

This article gives a detailed introduction to the main uses of grass ash for your reference.

1. Grass ash control of fruit tree diseases

1. Prevention of root rot

Open the soil at the root of the fruit tree, expose the roots, and scrape off the skin on the root with a knife. After 2-3 hours of rooting, apply fresh ash to the roots and then cover the roots. After treatment, the root of the disease can be cured in 1-2 months.

2, prevention and treatment of early leaf disease

The leaching solution was prepared by soaking with 8 kg of grass ash and 100 kg of water for 48 hours, and the liquid was mixed with the sterilizing agent to have a certain prevention and treatment effect on the early defoliation of fruit trees. When spraying the ash fertilizer on the foliage, use the clarified liquid after soaking to prevent the leaves from being contaminated.

3. Prevention and treatment of downy mildew

After the fruit enters the expansion period from July to August, the grass ash is applied on the ground or ditched in the tree tray. It can also be sprayed with 4% of the ash ash leaching solution, that is, 100 kg of water per 3-4 kg of ash and ash, and it is better to filter and spray after 24 hours of immersion.

4, prevention and control of rust

At an angle of 50 cm from the fruit tree, an annular groove with a width of 50 cm and a depth of 60 cm is dug, and the ash is applied into the ditch, the water is poured, and the new soil is pressed to have a certain control effect on the rust fruit disease.

5, prevention and control of blight, anthracnose

Fruit saplings are prone to blight and anthracnose, causing a large number of dead seedlings in severe cases. Use grass ash to spread the ridge, 30-50 kg per acre, can effectively prevent the occurrence of these two diseases.

6, control pear hibiscus

In the peak period of P. sylvestris from June to August, 3% of the ash ash soaking solution is sprayed on the pear tree, and after spraying for 3-4 hours, the insecticide can be effectively prevented.

7, control aphids

Use 10 kg of grass ash and add 50 kg of water, soak for 48 hours, and take the filtrate to spray, which can effectively control the mites on the fruit trees.

Second, the effect of the fertilizer of grass ash

1. Promote seed germination. After sowing the seeds, planting 0.5-1 cm with grass ash can increase the soil temperature, maintain the loose ventilation state, promote the seeds to germinate in advance, and grow the seedlings neatly and robustly, and the seedling rate is high.

2. Promote rooting. In crop transplanting, using plant ash with organic fertilizer as base fertilizer, or blending 5%-20% of plant ash in the preparation of nutrient soil, not only can increase the effective nutrients of the base fertilizer and nutrient soil, promote root growth, and reduce pests and diseases. effect.

3. Expanded fruit improves quality. Spraying 6%-8% of the ash-ash leaching solution on the foliage before and after flowering can promote the greening of the branches and leaves, promote the fruit enlargement, enhance the photosynthesis, reduce the loss of flowers and fruits, and improve the fruit quality.

4. Prevent yellow leaves from falling. Spray 10% of the ash ash leaching solution (10 kg of fresh grass ash is thoroughly stirred with 100 kg of clear water, filtered and clarified after standing for 24 hours) to supplement the nutrients, improve the vitality of the leaves, enhance photosynthesis, and prevent the leaves from yellowing and premature deciduous leaves.

5. Improve the drought resistance, cold resistance and stress resistance of the plants. For dryland crops with poor irrigation conditions, continuous spraying 5%-6% of ash-ash leaching solution can improve their drought resistance. Because the plant ash contains a lot of potassium ions, it can effectively weaken the strength of the transpiration water of the leaves and enhance the ability of the tree to resist drought, cold and stress.

3. There are many new uses for plant ash in agriculture.

1, fresh peppers. Put a layer of ash on the bottom of the bamboo raft or other storage utensils, then put a layer of kraft paper, then a layer of pepper and a layer of ash, and store it in a cool room (note: no water can be immersed in the ash during storage). This method stores peppers for up to four or five months.

2. Store potatoes and sweet potatoes. Potatoes and sweet potatoes without wounds were selected and covered with grass ash. The storage and preservation period can be up to six months. This method mainly uses the function of moisture absorption, heat absorption, heat preservation and inhibition of biological activities.

3. Storage of seeds. Prepare the storage tanks such as earthen jars and tile cylinders, wash and dry them, then use the grass and ash mat on the bottom, put a layer of kraft paper on top, put the seeds on the kraft paper, seal them with plastic film after installation, and the storage effect is good. Qi Miao, all seedlings, strong seedlings.

4, prevention and control of roots. When it is found that amaranth and garlic have root mites, the ash can be sprinkled on the leaves to control the adults, and the roots can control the root larvae.

5. Cover the oyster mushroom medium. Sowing oyster mushrooms in early spring, due to low temperature, hyphae development is slow, easy to be contaminated by bacteria, if a layer of grass ash is sprinkled on the surface, it can strengthen the greenhouse effect of the trampoline and promote the development of hyphae; the ash can also provide some nutrients for the hyphae. And can be a barrier to inhibit the growth of bacteria. Early spring sowing is covered with grass ash, which can make the mushrooming period 10 days earlier and increase production by about 20%.

6. Suppress the occurrence of pests and diseases. The grass ash is alkaline and has very fine particles. For example, it is in contact with the insects of the larvae, wheat mites, wheat spiders, and larvae. It can make the stomata obstruct and physiologically abnormal, and can kill some pests. Spreading grass ash can also inhibit the occurrence of wheat scab, stripe rust and powdery mildew.

7, prevention and control of bacterial blight. Putian used 10 kg of grass ash, 10 kg of tea cake, 1 kg of sulphur powder and 15 kg of lime to spread evenly on Putian (early, medium and late rice), which can effectively prevent the occurrence of bacterial blight in Putian.

8, prevention and control of seedling diseases. Fruit trees and flower nurseries, seedlings of dryland crops and vegetables are prone to blight, anthracnose, etc., causing a large number of dead seedlings in severe cases. It can be applied to the ridges with grass ash, 30-50 kg per acre, which can effectively prevent the virus from happening.

9. Increase the ground temperature. In winter, the base of the pepper tree is covered with a layer of ash, which can increase the ground temperature and prevent the root from being damaged by freezing.

Fourth, the advantages of grass ash in pond culture

1. It has the function of preventing fish disease: it has the function of sterilization and disinfection, and plays an important role in the prevention and treatment of fish diseases. It can effectively kill various pathogens in fish bodies; this can reduce the use of fishery drugs and help to improve The quality of the cultured aquatic products in Ganzhou can guarantee the quality and safety of aquatic products, as well as the role of removing moss.

2, has the effect of increasing fertilizer efficiency, and also used as a water body shade when killing moss, is a good auxiliary item.

3. Diligence has the function of regulating and purifying water quality: 70-120 kg of grass ash per acre of water can raise the pH of ponds with a depth of 1 m to 7.5-8.5, which is beneficial to the reproduction of planktonic plants and animals (improving phosphorus and potassium in water) The content of calcium, magnesium and other elements) provides sufficient high-quality natural bait for fish to improve the transparency of water bodies and is beneficial to the healthy ecological breeding of farmed fish.

Application method and precautions: After taking out the dry ash, put it in a container and soak it in water for 4-6 hours, take the whole leaching solution of the leaching solution, and do not use the ash that has been drenched in the application of the ash, and do not spray it directly with dry ash; In the process of application, it is best to choose a sunny afternoon to splash.

Five, disinfectant

The plant ash is a widely used disinfectant raw material in rural areas, and has a strong effect of killing pathogenic bacteria and viruses, and its effect is similar to that of the commonly used potent disinfectant caustic soda. The method is: using 2.3 kg of grass ash, heating water 10 kg can be used for disinfection of livestock houses, feeding troughs, utensils, and the like. In order to enhance the disinfection effect, 30 kg of grass ash can be used, and 100 kg of water can be added. After boiling for 1 hour in the pot, the slag is filtered and used for disinfection of livestock houses and utensils such as pig plague, foot-and-mouth disease, chicken Newcastle disease and the like. The disinfectant has the characteristics of strong disinfection, no side effects, no irritation and the like.
