Embodiment 1
[0024] 1. Selection and pretreatment of Eucommia seedlings
[0025] Select the Eucommia ulmoides seedlings that grow vigorously and be about 5cm at 10cm from the ground as the mother plant, set to dry 60cm, and paint at the top of the trunk (cutting the dry mouth and its vicinity) to prevent the trunk from drying up due to water evaporation.
[0026] 2. Eucommia seedlings raised
[0027] Dig a circular tree hole with a diameter of about 40cm around the mother plant, cut off the roots outside the circular tree hole (radius 20cm) and at the bottom (minimize excessive damage to the root bark during the root cutting process), and remove the roots in the circular tree hole. The soil clod is dug out together with the mother plant, and liquid fertilizer is sprayed on the broken root part to promote the root formation of new shoots.
[0028] 3. Bagging of seedlings
[0029] Put the mother plant with soil clods into a cylindrical seedling bag with a diameter of 50cm, a height of 40cm...
Embodiment 2
[0037] 1. Selection and pretreatment of Eucommia seedlings
[0038] Select the Eucommia ulmoides seedlings that grow vigorously and be about 7cm at 12cm from the ground as the mother plant, dry 50cm, paint on the top of the trunk (cut dry mouth and its vicinity) to prevent the trunk from drying up due to moisture evaporation.
[0039] 2. Eucommia seedlings raised
[0040] Dig a circular tree hole with a diameter of 45cm around the mother plant, cut off the roots outside the circular tree hole (radius 22.5cm) and at the bottom (minimize excessive damage to the root bark during the root cutting process), and place the roots in the circular tree hole The soil clod is dug out together with the mother plant, and liquid fertilizer is sprayed on the broken root part to promote the root formation of new shoots.
[0041] 3. Bagging of seedlings
[0042] Put the mother plant with soil clods into a 60cm in diameter, 40cm in height, air-permeable, light-transmitting cylindrical nursery ...
Embodiment 3
[0050] 1. Selection and pretreatment of Eucommia seedlings
[0051] Select the eucommia ulmoides seedlings that grow robustly and grow around 4cm at 10cm from the ground as the mother plant, dry 50cm, and paint at the top of the trunk (cutting dry mouth and its vicinity) to prevent the trunk from drying up due to water evaporation.
[0052] 2. Eucommia seedlings raised
[0053]Dig a circular tree hole with a diameter of 40cm around the mother plant, cut off the roots outside the circular tree hole (radius 20cm) and at the bottom (minimize excessive damage to the root bark during root cutting), and remove the soil in the circular tree hole Dig out the block together with the mother plant, and spray liquid fertilizer on the broken root part to promote the formation of new shoots.
[0054] 3. Bagging of seedlings
[0055] Put the mother plant with soil clods into a cylindrical seedling bag with a diameter of 50cm, a height of 40cm, air permeability and light transmission, place...
