The function of grass ash

The ash is the ash fertilizer formed after the burning of firewood, and it is a kind of hot and quick-acting fertilizer with loose texture.

The function of grass ash:

1. Promote rooting: In the transplanting of seedlings, use plant ash with organic fertilizer as base fertilizer, or mix 5% to 20% of ash to ash when preparing nutrient soil, not only can increase the effective nutrients of the base fertilizer and nutrient soil, and promote root growth. There is also the role of reducing pests and diseases.

2. Promote seed germination: After planting the seed of the tree, cover the plant with 0.5-1 cm of the ash, which can increase the soil temperature, maintain the loose and ventilated state, promote the seed to germinate in advance, and grow the seedlings neatly and robustly, and the seedling rate is high. .

3. Prevention of defoliation: Spray 10% ash leaching solution of fresh grass ash (10 kg of fresh grass ash and 100 kg of water, stir well, let stand for 14 to 16 hours, filter after slag clarification), supplement the nutrients, and improve the vitality of the leaves. Enhance photosynthesis and promote beautiful flowers and fruits.

4. Improve the drought resistance of fruit trees: For the dryland fruit trees with poor irrigation conditions, spray 2-3~6% of the ash ash leaching solution for 2~3 times to improve the drought resistance of the fruit trees. Because the plant ash contains a large amount of potassium ions, it can effectively weaken the strength of the transpiration water of the fruit trees and enhance the drought resistance and high temperature resistance of the trees.

5. Improve the quality: Spray 50~80% of the ash ash leaching solution on the foliage before and after flowering, which can promote the green leaves and bright flowers and leaves, enhance photosynthesis, reduce flower and fruit detachment, and improve fruit quality.
