The survival rate of tea seedlings plays a crucial role in determining the yield for the following year. To maximize income from early production, it is essential to implement effective measures across several key areas:
1. **Choosing the Right Planting Time**: The best time to transplant tea seedlings is when root growth has slowed down but the plant is still actively growing. This usually occurs during late autumn (mid-October to November) or early spring (late February to March), with autumn being the most favorable season for planting.
2. **Controlling Seedling Quality**: Before transplanting, ensure that the roots are wrapped in moist soil to minimize root damage. The size of each bundle should be moderate, ideally containing 50 to 100 plants. After bundling, it's recommended to coat the roots with yellow mud and wrap the base with straw or similar materials. For long-distance transport, protect the seedlings from direct sunlight and wind, and stack them tightly to maintain freshness. If planting cannot be done immediately, store the seedlings in a cool, shaded area and mist them regularly or temporarily plant them in a suitable location.
3. **Careful Planting Procedures**: When transplanting, dig a planting trench that is about 20–25 cm deep and fill it gradually with soil. Ensure the ground is level and water the roots thoroughly. It's also important to prune the leaves and branches above 15–20 cm from the ground to reduce water loss through transpiration.
4. **Drought Resistance Measures**: The second year, especially during hot and dry periods, is critical for the survival of tea seedlings. Before the onset of high temperatures, perform weeding and apply fertilizer to improve soil conditions. Watering should be done if possible, and shade can be provided using fresh pine branches or other suitable materials.
5. **Timely Pest Control**: Due to the open spaces between tea plants, weeds grow quickly and compete for nutrients and water, which can lead to pest and disease problems. Regular weeding is necessary, and special attention should be given to underground pests such as root borers and leafhoppers that can damage buds and young leaves.
By following these practices, you can significantly improve the survival rate of your tea seedlings and set the stage for a successful harvest in the coming seasons.
