Promote seed germination. After planting the seed of the forest, planting 0.5-1 cm with the plant ash can increase the soil temperature, maintain the loose ventilation state, promote the seed to germinate in advance, and the seedlings are neat and robust, and the seedling rate is high.
Promote rooting. In the transplanting of seedlings, using plant ash with organic fertilizer as base fertilizer, or blending 5%-20% of ash in the preparation of nutrient soil, not only can increase the effective nutrients of the base fertilizer and nutrient soil, promote root growth, and reduce pests and diseases. effect.
Prevent falling leaves. Spray 10% of the ash ash leaching solution (10 kg of fresh grass ash is thoroughly stirred for 100 kg of clear water, filtered after standing for 14-16 hours, and slag can be sprayed after clarification) to supplement the nutrients, improve the vitality of the leaves, prevent early leaves, and enhance Photosynthesis promotes beautiful flowers and fruits.
Improve quality. In addition to a large amount of nutrients such as potassium and calcium, the plant ash also contains various trace elements such as iron and magnesium, and has quick-acting properties, and is a high-quality foliar fertilizer. Spraying 50%-80% of the ash ash in the foliage before and after flowering can promote the greening of the branches, enhance photosynthesis, reduce the loss of flowers and fruits, promote the blooming of flowers and fruits, prolong the viewing period and improve the fruit quality.
Inhibit pests and diseases. 30-50 kg of grass ash per mu of nursery can kill underground pests and germs, protect seeds, roots and stems, reduce pests and diseases, and prevent the occurrence of blight and anthracnose. The application of plant ash in the orchard can control the occurrence of powdery mildew and fruit rust, and the effect of controlling root rot is 2.5-5 kg ​​per plant. Spraying 2%-3% of the ash ash leaching solution can control pests such as aphids and spider mites on flowers and fruits, and improve the drug control effect of hibiscus.
Improve the drought resistance of fruit trees. For dryland fruit trees with poor irrigation conditions, continuous spraying 5%-6% of ash-ash leaching solution can improve the drought resistance of fruit trees. Because the plant ash contains a lot of potassium ions, it can effectively weaken the transpiration water intensity of the fruit trees, enhance the drought resistance and high temperature resistance of the trees, promote the operation of carbohydrates, and improve the disease resistance and insect resistance of the trees.
It should be noted that the grass ash is alkaline, can not be mixed with acidic fertilizers and pesticides, and the foliage is sprayed with ash leaching solution, which is used after filtration and clarification to prevent pollution of leaves, flowers and fruits.
