1、 Cultivation skills

1. Thick soil planting: when planting with down hill piles, it needs to be planted with thick soil because it needs moisture and heat preservation. In order to prevent the water loss of the tree stump, wet sand can be used to cover two-thirds of the tree stump until the plant sprouts new buds. After the plant survives, the cultivation soil can be gradually reduced. In addition, the plant can also be covered with plastic film to reduce water loss. Do not use clay and nutrient soil with too much fertility

2. Spraying water to induce roots: because elms like to dry and fear waterlogging, excessive watering during cultivation will rot the roots, but insufficient watering is difficult to take root. Therefore, sprays are often used to spray water on the stump and spray water into the soil or roots. p>

3. Proper shading: reduce the light during pile raising. When elm trees are planted down the mountain, they need shade all year round. It's best to put them in the shade

4. Application of light fertilizer: excessive fertilizer will cause fertilizer damage to the root. The plant's own reserves and the original fertilizer in the soil are enough to restore its growth. During the pile raising period, topdressing is not required for one to two years

5. Suitable temperature pile: after the plant survives, the cold resistance will be seriously reduced, so thermal insulation measures need to be taken in winter. Thick soil can be used to cover outdoor plants, and potted plants can overwinter indoors, but the room temperature should not be too high

2、 How

First, place the elm stump down the mountain in a cool place to dry the root, and apply medicine such as erythromycin ointment to the stump wound. In addition, you can apply rooting powder to the root of the stump to make it take root quickly. When planting outdoors, you can first plant the stump into the ground and water it after a week or so. If it is an indoor potted plant, it can be planted with wet sandy soil first. After the soil is covered and compacted, do not water it for at least three days, and let it recover its growth
