1. Promote germination: After planting the flowers and trees, level the noodles, cover 1 cm to 2 cm with the ash, and apply the soil temperature in the morning and evening in the windless season to keep the soil loose and promote the seeds 7 days in advance. Sprouting in 10 days, and the seedlings grow neatly and robustly.
2. Accelerated rooting: During the transplanting process, the planting ash is mixed with the organic fertilizer to make the base fertilizer, or the auxiliaries are mixed with 5% to 20% of the ash, which can increase the absorbability of the fertilizer, promote wound healing, and improve The survival rate of seedling transplanting. In the process of transplanting and changing pots, flowers such as Clivia can be used to cut off rotten roots, spray grass ash on wounds and roots, control rotten roots, promote new roots, and restore their growth. The effect is more significant when transplanting large seedlings.
3. Prevention of defoliation: Spraying 8% to 15% of the ash ash leaching solution during the growing season of flowers and trees, as a top dressing, can improve the photosynthetic efficiency of the leaves, prolong the growth period of the leaves, promote the beauty of the leaves, and enhance the ornamental effect.
4. Prevention and treatment of insects: spraying 3% to 5% of ash and ash leaching solution, as well as controlling pests such as mites and red spiders.
5. Enhance stress resistance: planting flowers and trees in arid areas such as hills and hills, and continuously spraying 3% to 5% of ash ash leaching solution to improve 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 of drought resistance and high temperature. Potassium ions can also promote the operation of carbohydrates and improve the resistance of flowers and trees.
6. Prevention of injury: Flowers such as grapes, figs, sago, etc., which are prone to injury, can be wounded after trimming or changing pots, and fresh grass ash can be applied to control the wound flow, prevent wound infection and decay, and promote healing.
In the course of use, it should be noted that the vegetation ash is alkaline and cannot be mixed with acidic fertilizers and pesticides to avoid reducing the effectiveness of pesticides and fertilizers.
