The effect of plant ash on crops

Grass ash is the ash that is formed after the burning of firewood and belongs to the loosely available potassium fertilizer. It generally contains 5% to 15% of effective potassium, and also contains calcium, magnesium, sulfur, phosphorus, and iron. Its role is:

1. Promoting Germination: After planting, squash is planted and covered with plant ash to cover 1 cm to 2 cm. It should be applied on windless mornings and evenings. It can effectively increase the soil temperature, keep the soil loose, and promote seeds 7 days in advance. It germinates until 10 days and the seedlings grow neatly and robustly.

2. Accelerating Rooting: In the process of transplanting flowers and trees, the use of grass ash and organic fertilizers are fully mixed as the base fertilizer, or 5% to 20% of the plant ash is added when preparing nutritious soil, which can increase the absorbability of the fertilizer, promote wound healing, and improve The survival rate of transplanting seedlings. In the transplanting process, flowers such as Clivia are cut off from rot, sprayed on the wounds and roots to control rot, promote new roots, and restore their growth. It is more effective when transplanting large seedlings.

3. Preventing defoliation: spraying 8% to 15% of ash leaching liquid during the growth season of flowers and trees, as a top-dressing fertilizer, can increase the photosynthetic efficiency of the leaves, extend the growth period of the leaves, promote the beauty of the leaves, and enhance the ornamental effect.

4. Disease prevention and pest control: spraying 3% to 5% of the ash leaching fluid, as well as the role of control of aphids, red spiders and other pests.

5. Strengthen stress resistance: Planting flowers and trees in arid areas such as hilly hills and continuously spraying 3% to 5% of the leaching liquid of the ash to increase the drought resistance of flowers and trees. Because the plant ash contains a large amount of free potassium ions, it can reduce the transpiration intensity of the leaves and enhance the ability to resist drought and high temperature. Potassium ions can also promote the operation of carbohydrates and improve the resistance of flower trees.

6. Prevent Injury: Flowers and trees that are prone to injury, such as grapes, figs, cycads, etc. The wounds created after trimming or changing basins are freshly treated with ash, which can control the wound flow, prevent the infection from decaying, and promote healing.

During use, it should be noted that the ash in the plant is alkaline and cannot be mixed with acidic fertilizers or pesticides to avoid reducing the effectiveness of pesticides and fertilizers.
