The plant ash is the ash fertilizer formed after the firewood is burned, and it is a hot, quick-effect fertilizer with loose texture. The main component of plant ash is potassium, which also contains phosphorus, calcium, iron, magnesium, sulfur and other effective nutrients and a small amount of trace elements such as boron, aluminum, and manganese. Potassium promotes nitrogen metabolism and carbohydrate synthesis and transportation in plants, which can promote robust plant growth and enhance its ability to resist pests and natural disasters. The plant ash is suitable for acidic soils or cohesive soils. It is particularly suitable for use in crops such as sweet potatoes and potatoes, as well as in the cultivation of nursery and nursery crops. It has a wide range of uses in fruit and tree production.
The function of plant ash
1. To promote seed germination: After planting the forest seed, cover it with plant and wood ash 0.5-1 cm, which can increase the soil temperature, maintain loose ventilation state, promote the seeds to germinate in advance, and the grown seedlings are neat and robust, with high seedling rate. .
2. Promote rooting: In the transplanting of seedlings, the use of plant ash with organic fertilizer as base fertilizer, or in the preparation of nutrient soil when mixed with 5% to 20% of the plant ash, not only can increase the effective nutrients of base fertilizer and nutrient soil, promote root growth, There is also the role of reducing pests and diseases.
3 to prevent defoliation: spray 10% of ash leaching liquid (100 kg of fresh grass ash mixed with 100 kg of water, stir well, after standing for 14 to 16 hours after filtration, slag can be sprayed after clarification) for additional nutrients, can increase leaf vitality, Enhance photosynthesis and promote beautiful flowers and berries.
4. To improve the quality: Spraying 50 to 80% of the ash leaching solution on the leaves before and after flowering can promote green foliage and bright flowers, enhance photosynthesis, reduce flower and fruit loss, and improve fruit quality.
5. To improve the drought resistance of fruit trees: For dryland fruit trees with poor irrigation conditions, spray 2 to 3 times of 5% to 6% of the ash leaching liquid, which can improve the drought resistance of fruit trees. Because the plant ash contains a large amount of potassium ions, it can effectively reduce the intensity of transpiration water in the leaves of fruit trees and enhance the ability of the tree to resist drought and heat.
