The ash remaining after the burning of crop stalks, firewood, litter, etc. is collectively referred to as ash. The plant ash is rich in nutrients and contains various mineral elements required by plants, of which potassium and calcium are the most, phosphorus is the second, and other elements are also significantly higher than other farmyard fertilizers. Practice has proved that the use of plant ash soil, the crop rarely occurs mineral element deficiency. Promoting seed germination Covering 0.5 to 1 cm with plant ash can increase soil temperature, maintain loose ventilation, encourage seeds to germinate in advance, and grow seedlings that are neat, robust, and have a high percentage of seedlings. Promote rooting In the transplanting of seedlings, the preparation of nutrient soil when mixed with 5% to 20% of the plant ash, not only can increase the effective nutrients of base fertilizer and nutrient soil, promote root growth, but also reduce the role of pests and diseases. Improve the quality Before and after flowering, spraying 50% to 80% of the ash on the leaves can promote green foliage and bright flowers, enhance photosynthesis, reduce flower and fruit loss, and improve fruit quality. Preventing deciduous spraying of 10% ash leaching liquid as a supplementary nutrient can increase the vitality of leaves, enhance photosynthesis, and promote beautiful appearance of flowers and fruits. Improve Drought Resistance For dry land crops with poor irrigation conditions, spray 2-3 times of 5%-6% ash leaching fluid continuously to improve its drought resistance. Because the plant ash contains a large amount of potassium ions, it can effectively reduce the intensity of transpiration water in the crop leaves and enhance the ability of the tree to resist drought and high temperature. Grass ash application The plant ash can not be mixed with ammonium nitrogen fertilizer, nor can it be mixed with organic fertilizers such as human waste and circulatory fertilizers, and it cannot be mixed with superphosphate. In order to increase the efficiency of plant ash, it should be applied separately. At the same time, as more than 90% of its own potash is soluble in water, it is a quick-acting potash fertilizer. According to this characteristic, ash can be used as basal fertilizer, seed fertilizer and topdressing fertilizer, and its aqueous solution can also be used for top dressing. For basal fertilizer and seed fertilizer, the amount of fertilizer should not be too large. The amount of mu is generally 50 to 100 kg. Plant ash is suitable for any crop, but due to limited sources, it should be given priority to be applied to potassium-depleted soil in order to give full play to the fertilizer efficiency of ash. Followed by the preferential application of hi potassium crops, such as potatoes, sweet potatoes, cotton and legumes, etc., the average annual dose of 30 ~ 50 kg is appropriate. In particular, crops such as tobacco and potato that are resistant to chlorine and potassium are more efficient than chemical potash fertilizer.
