The plant ash contains various potassium salts, of which potassium carbonate is the main component, followed by potassium sulfate and a small amount of potassium chloride, which are physiological alkaline fertilizers. Therefore, the grass ash cannot be mixed with the ammonium nitrogen fertilizer; Mix organic fertilizers such as ring fertilizer. In order to improve the efficiency of ash and ash, it is necessary to carry out single-single sputum and apply alone. The ash is the ash fertilizer formed after the burning of firewood, and it is a kind of hot and quick-acting fertilizer with loose texture.
The function of grass ash:
- 1. Promote rooting: In the transplanting of seedlings, use plant ash with organic fertilizer as base fertilizer, or mix 5% to 20% of ash to ash when preparing nutrient soil, not only can increase the effective nutrients of the base fertilizer and nutrient soil, and promote root growth. There is also the role of reducing pests and diseases.
- 2. Promote seed germination: After planting the seed of the tree, cover the plant with 0.5-1 cm of the ash, which can increase the soil temperature, maintain the loose and ventilated state, promote the seed to germinate in advance, and grow the seedlings neatly and robustly, and the seedling rate is high. .
- 3. Prevention of defoliation: Spray 10% ash leaching solution of fresh grass ash (10 kg of fresh grass ash and 100 kg of water, stir well, let stand for 14 to 16 hours, filter after slag clarification), supplement the nutrients, and improve the vitality of the leaves. Enhance photosynthesis and promote beautiful flowers and fruits.
- 4. Improve the drought resistance of fruit trees: For the dryland fruit trees with poor irrigation conditions, spray 2-3~6% of the ash ash leaching solution for 2~3 times to improve the drought resistance of the fruit trees. Because the plant ash contains a large amount of potassium ions, it can effectively weaken the strength of the transpiration water of the fruit trees and enhance the drought resistance and high temperature resistance of the trees.
- 5. Improve the quality: Spray 50~80% of the ash ash leaching solution on the foliage before and after flowering, which can promote the green leaves and bright flowers and leaves, enhance photosynthesis, reduce flower and fruit detachment, and improve fruit quality.
More than 90% of the potassium salt contained in the plant ash is soluble in water and is a quick-acting potash. Therefore, the plant ash can be used as the base fertilizer, seed fertilizer and top dressing, and its aqueous solution can also be used for top dressing.
It is advisable to use grass ash for concentrated application, and it can be applied by strips and acupoints. The depth is 8-10 cm, and the soil is covered after application. Mix 2 to 3 times of wet soil before application or spray it with a little water to prevent ash from flying.
The amount of grass ash is limited, and it should first be applied to the potassium-deficient soil in order to give full play to the fertilizer effect of the ash. Generally speaking, the sandy soil with coarse soil texture is mostly potassium-deficient soil, and the effect is very obvious after applying the ash. Secondly, it is preferentially applied to crops with potassium, such as potatoes, sweet potatoes, cotton, and legumes. The annual acre is generally 30-50 kg.
The ash remaining after burning crop stalks, firewood, litter, etc. is collectively referred to as ash, which is an important source of fertilizer in farmyard soil. After entering the winter, most of the rural areas in the north rely mainly on burning straw, firewood and so on. Therefore, this is the golden season for accumulating grass and ash.
It has been determined that the nutrients of the plant ash are extremely rich and contain various mineral elements such as potassium, phosphorus, calcium, magnesium, sulfur, boron, silicon, sodium, iron, manganese, copper, zinc, molybdenum, etc. Calcium is the most, followed by phosphorus; the content of other elements is also significantly higher than other farmyard manure. According to the survey, the application of grass ash soil, crops rarely occur mineral element deficiency, so the grass ash was praised by the masses as "complex fertilizer containing more nutrients."
During the process of planting ash and ash, it should be stored separately in a special ash silo or shed to prevent wind and rain to avoid loss of fertilizer; the ash is an alkaline fertilizer and should not be mixed or mixed with ammonium nitrogen fertilizer, nor should it be used. Mixed with human and animal excrement, the plant ash is rich in calcium, and should not be mixed with and mixed with superphosphate to avoid the fixation of phosphorus.
In addition to saline-alkali soil, the plant ash is suitable for all kinds of soils, and can be directly applied to the soil (applied with turbid wet soil after mixing, 50-100 kg of ash per mu), and can also be used with ash (10% concentration) of ash Spray on the surface. Grass ash is suitable for any crop, but due to limited sources, it should be used preferentially for sugar beet, potato, sweet potato, sunflower, tobacco, fruit and vegetable vegetables and berry fruit trees; especially for tobacco, potato and other crops that avoid chlorhexidine, grass ash The fertilizer effect is higher than the chemical potash.
- 1. The plant ash contains various potassium salts, among which potassium carbonate is the main type, which is an alkaline fertilizer. Therefore, the ash can not be mixed with the ammonium nitrogen fertilizer; it can not be mixed with organic manure such as human excrement or manure; Calcium is administered in combination. When the plant ash is mixed with the superphosphate, some of the available phosphorus in the superphosphate will be fixed as the ineffective phosphorus, thereby reducing the fertilizer efficiency of the phosphate fertilizer. In order to improve the efficiency of ash and ash, it is necessary to carry out single-single sputum and apply alone.
- 2. The potassium salt contained in the plant ash is more than 90% soluble in water and is a quick-acting potassium fertilizer. According to this characteristic, grass ash can be used as base fertilizer, seed fertilizer and top dressing, and its aqueous solution can also be used for top dressing. When used as a base fertilizer or a seed fertilizer, the amount of fertilizer should not be too large, and it should be isolated from the seeds to prevent burning. The amount of acre is generally 50 to 100 kg.
- 3. The plant ash is suitable for centralized application, and can be applied by strips and acupoints. The depth is 8~10cm, and the soil is covered after application. Mix 2 to 3 times of wet soil before application or spray it with a little water to prevent ash from flying.
