Grass ash is a common organic fertilizer used by farmers. It contains many nutrients necessary for crop growth, and it also has the effects of promoting growth, disinfecting and preventing various diseases. It can be said that it is a "magic weapon" for the growth of crops. The following small series will tell you about the use of the fertilizer value of the plant ash.     1. What are the nutritional values ​​of grass ash? The ash is the residue left by burning herbs or woody plants. The plant ash is an alkaline, water-soluble hot quick-acting fertilizer. Potassium carbonate is its main component. The highest content of potassium and phosphorus, the highest potassium can reach 6-12%, the phosphorus content is 1.5-3%, and the boron content. It can also reach 2-3%, in addition to calcium, magnesium, sulfur, zinc, copper, iron, manganese, molybdenum, silicon and many other medium and micronutrients.     2. What are the benefits of using ash for ash in field crops?     1. Supplemental potash As a kind of high-quality ecological potash fertilizer, grass ash can supplement potash fertilizer for soil and crops, promote the synthesis and transport of sugar, carbohydrate and protein in crops, and enhance the drought resistance, cold resistance, lodging resistance and salt and alkali resistance of crops. The physiological resistance can improve the yield and quality of crops.     2, germination promotes long After the crop is planted, a thin layer of ash (0.5-1 cm) is applied to the surface, which not only keeps the soil loose and breathable, but also raises the ground temperature. It can promote the early germination, early emergence, and emergence of seeds. Out of the seedlings. When transplanting flower seedlings, blending grass ash with organic fertilizer and soil can not only increase nutrients, improve fertilizer efficiency, but also accelerate the healing and recovery of injured roots of transplanted seedlings. It can also inhibit rotten roots and promote new roots. The role of improving the survival rate after transplanting.     3. Prevention and control of pests and diseases 1 Prevention and treatment of wounds: Fruit trees and seedlings with wounds can be smeared with fresh ash, which not only can sterilize and disinfect, control the flow of wounds, prevent the infection of diseases, but also accelerate the healing of wounds. 2 Prevention of root rot: For crops or fruit trees that have root rot, first clean the soil around the roots, and then cover the roots with grass ash. In addition, in the rainy season, in order to prevent the roots from appearing on the fruit trees, a layer of 10 cm thick grass ash can be applied to the tree tray, which not only prevents the fruit trees from being smashed, but also supplements the fruit trees with potassium fertilizer and enhances the fruit quality. . 3 Prevention and control of roots: Garlic, leeks and other crops are exposed to root mites. Planting ash is applied to the roots of crops to control root larvae. 4 Prevention and control of various pests: Spraying fruit tree crops with 0.3-0.5% concentration of grass ash filtrate can control pests such as aphids, red spiders, and pear hibiscus. 5 Prevention and control of various vegetable diseases of charcoal: 30-50 kg of grass ash per mu is applied to prevent frequent occurrence of anthracnose, blight, powdery mildew, fruit rust, virus disease and other diseases, and reduce crop seedling period. The phenomenon of dead seedlings can be used to control wheat scab, stripe rust and powdery mildew in wheat fields.     4, enhance the resistance For crops with low precipitation, drought, or low temperature, spray about 0.5% of the plant ash filtrate continuously for 2-3 times, or apply to the field soil, the potassium ions in the plant ash can not only reduce the evaporation of leaf moisture and Evaporation intensity accelerates the formation and operation of carbohydrates in crops, which can improve the resistance to high temperature and drought. Protect crop roots from freezing damage.     5, prevent premature aging, improve yield and quality Spraying the plant ash filtrate on the crop can not only enhance the photosynthesis of the crop leaves, but also supplement the crop with calcium, magnesium, sulfur, zinc, iron and other medium and trace elements, which can reduce the phenomenon of falling flowers and fruit, and promote the fruit. It has a healthy growth and expansion, and it has a very good growth, yield and quality improvement.    6, store seeds and potatoes Because the ash has good heat absorption, moisture absorption, heat preservation and bactericidal effect, potatoes, sweet potatoes, etc. can be buried in the grass ash for half a year; in addition, when storing seeds, the ash can be sprinkled at the bottom with kraft paper. In the container, the seeds are then placed on kraft paper for sealing, and when used for sowing, it is ensured that the seeds are ready to emerge and emerge.     3. What are the precautions when using ash in the field? 1. Grass ash is an alkaline fertilizer. It should not be mixed with or stored with acid fertilizer/pesticide, ammonium nitrogen fertilizer, calcium phosphate, etc., otherwise it will neutralize fertilizer efficiency and reduce fertilizer effect. 2. The plant ash is a fast-fertilizer and should not be used together with the farmer's urine manure that has been poured into the late-effect farm. Otherwise, it will cause the fertilizer to evaporate and reduce the effect of fertilizer. 3, the plant ash is a water-soluble, easy-to-wind fertilizer, should be stored in this shelter from the wind, the wind is easy to be blown away, and the potassium will be lost in the rain. Grass ash is a non-hazardous ecological farmhouse potash fertilizer, which has a good effect on crop growth, but the premise is to understand clearly and use it properly. Otherwise, it will be counterproductive. The above is about the introduction and use of the nutritional value of the plant ash, so you can collect it.
