How to select Yew seeds? What are the seedling raising methods?

Yew is also known as Chinese yew, and is a first-class protected plant in China, known as the "giant panda of trees". Its main value lies in its strong ornamental appeal and good medicinal properties. Since yew is currently in an endangered state, the cultivation and breeding of yew is very important. Of course, to grow yew well, seed selection and seedling raising are key. Let's learn about them in detail together.

How to select seeds of yew?

Yew is generally cultivated by seed propagation, so the quality of seed selection directly affects its physiological maturity. First, use a fine sieve to select the seeds stored in wet sand. Because yew seeds can only germinate after two winters and one summer, mature seeds that have not been treated can only break dormancy after more than one year of stratification to promote germination. Therefore, after selecting good seeds, soaking treatment is also needed. You can soak the seeds with 60% concentrated sulfuric acid for 3h, which can ensure the vigor of yew seeds.

What are the seedling raising methods?

1. Nursery site selection

During the sowing stage of yew seed seedling raising, the nursery site must be selected scientifically. The nursery site needs to ensure that drainage, nutrients, and soil quality all meet the breeding requirements. After selection, it also needs to be deeply plowed and fertilized.

2. Bed making

When carrying out land preparation, the soil on the soil layer needs to be divided into nursery plots with a width of 1.2m, a height of 20cm, and a width of 0.4m, and the surroundings of the ridges should be reinforced to ensure the normal progress of later operations such as watering.

3. Sowing

Before sowing, the nursery needs to be divided into compartments for bed making. The height of the bed needs to be 15 cm-20 cm, and the width needs to be 1.2 m. On the leveled compartment surface, use a wooden board with a width of 15 cm to press out sowing furrows 2 cm deep, and then sow.

4. Seedling cultivation

After the seeds emerge, because the seedlings are very afraid of direct sunlight, a shade shed needs to be built over the nursery, and the light transmittance of the shade shed should be 15-20 percent. After building the shade shed, weeds must be removed once every 15 days-20 days, and urea must also be applied once at the same time. This can accelerate seedling growth, and after 1 year they can be transplanted.

5. Pest and disease control

In the process of yew seed seedling raising, the control of some common pests and diseases is very important. This is one of the important guarantees for ensuring the survival rate of seed seedling raising. For example, aphid disease is one of the common diseases of yew. If greenhouse seedling raising is chosen during the seed seedling raising process, it must be ensured that the temperature in the greenhouse is controlled above 18 degrees C, and 10% imidacloprid emulsifiable concentrate should be selected and applied to the seedling bed. This method has a very good control effect and can effectively manage aphids.

Overall, as a rare tree species in China, yew must have its seed selection and seedling raising techniques well mastered during cultivation. Only then can it benefit subsequent growth and development, improve the survival rate of yew, and also bring better returns to growers.
