Generally, it is better to dig elm trees in the field in winter and spring, that is, in March and April.At this time, the elm tree enters the dormant period, and the survival rate of digging stump planting will be improved.In addition, it is better to dig the stump in cloudy days or light rain, which can avoid excessive water consumption and is conducive to the survival of the stump.If it is excavated in sunny weather, it is necessary to do a good job of shading and moisturizing measures in advance, so as to avoid evaporation of a large amount of water from branches and leaves, which makes it difficult for stumps to survive.
1. Pruning: Before planting, the roots and branches should be pruned, and the dead roots, diseased roots and too messy roots should be cut off.When pruning the roots, there may be sticky sap coming out.If the sap oozes out too much, you can use wax to seal the incision, or apply a layer of erythromycin ointment, and then sprinkle fine sand to allow it to heal.
2. Pile: Elm tree stump dug in the field should be planted in river sand land or planted in pots for pile raising to improve its survival rate.Do not spray or soak it immediately, otherwise it will lead to excessive humidity of roots or trunks, wound healing is difficult, seriously affecting the survival rate of elm.
3. Soil: You can choose sand or sandy soil as a culture substrate, but also for the substrate to do a good job of moisturizing.
4. Illumination: shading measures should be taken in the first year of planting.Especially in summer, avoid direct light and exposure, and cool the temperature in autumn, so that plants can receive appropriate light.
5. Watering: Do not water the plant after planting, and do a good job of moisturizing and heat preservation measures.After about 3-5 days, it can be watered with root fixing water.
