Core tips: The role of plant ash - plant ash is the ash formed after the burning of firewood, which belongs to the fast-acting potassium fertilizer with a loose texture, generally contains 5% to 15% available potassium, and also contains calcium, magnesium, sulfur, phosphorus, and iron. Experts from Dongfang Forest Mao Yu Forest introduce the role of plant ash. 1. Promote germination: After the flowers and trees are sown, level the bed surface and use grass

The role of plant ash - plant ash is the ash formed after the burning of firewood, which is a fast-acting potassium fertilizer with a loose texture, generally containing 5% to 15% available potassium, and also contains calcium, magnesium, sulfur, phosphorus, and iron.

1. Promote germination:Flowers and treesAfter sowing, level the bed surface, cover it with plant ash by 1 cm to 2 cm, and spray it in the windless morning and evening, which can effectively raise the soil temperature, keep the soil loose, and promote the germination of seeds 7 to 10 days in advanceSeedlingsGrow neatly and robustly.

2. Accelerate rooting: In the process of transplanting, use plant ash and organic fertilizer to fully mix as a base fertilizer, or mix 5% to 20% plant ash when preparing nutrient soil, which can increase the absorption of fertilizer, promote wound healing, and improve the survival rate of seedling transplanting. Clivia et alFlowersIn the process of transplanting and repotting, cut off the rotten roots and spray plant ash on the wound and root system, which can control the rotten roots, promote the development of new roots, and restore their growth. The effect is more significant when transplanting large seedlings.

3. Prevent leaf fall: Spraying 8% to 15% plant ash extract during the growing season of flowers and trees as an extra-root top dressing can improve the photosynthetic efficiency of leaves, prolong the growth period of leaves, promote the beauty of flowers and leaves, and improve the ornamental effect.

4. Disease prevention and control: spraying 3% to 5% plant ash extract, as well as controlling aphids, spider mites and other pests.

5. Enhance stress resistance: Planting flowers and trees in arid places such as mountains and hills, and continuously spraying 3% to 5% plant ash leachate can improve the drought resistance of flowers and trees. Because plant ash contains a large amount of free potassium ions, it can reduce the transpiration strength of leaves, enhance the ability to resist drought and high temperature, and potassium ions can also promote the operation of carbohydrates. Improve the resistance of flowers and trees.

6. Prevent wound flow: Flowers and trees that are prone to wounds such as grapes, figs, cycads, etc., applied fresh plant ash to wounds caused after pruning or repotting, can control wound flow, prevent wound infection and rot, and promote healing.

In the process of using plant ash, it should be noted that plant ash is alkaline and cannot be mixed with acidic fertilizers and pesticides, so as not to reduce the effectiveness of pesticides and fertilizers.
