The seeds of Taxus chinensis can be directly planted, but in practical operation, it is usually recommended to carry out certain pretreatment to improve the germination rate and growth quality of the seeds. The following is a detailed explanation of direct planting of Taxus chinensis seeds and related precautions: Characteristics of Taxus chinensis seeds
Form and Size: The seeds of Taxus chinensis are egg shaped, with a length of approximately 7cm. The upper part is wider and the lower part is narrower, forming an inverted shape.
Color and wrapping: The seeds are wrapped in a red fleshy cup-shaped false seed coat, which gives the seeds a red color.
Dormancy characteristics: The seeds of Taxus chinensis have a deep dormancy characteristic, which usually requires two winters and one summer to germinate in their natural state. Pre treatment of Taxus chinensis seeds
To improve the germination rate of Taxus chinensis seeds, the following pretreatment measures can be taken:
1. Soaking treatment: Soak the seeds in water for 3-5 days, crush and wash the skin of the false seeds, and then dry them in the shade. This step helps soften the seed coat and improve the water absorption of the seeds.
2. Germination treatment: Bury the seeds every other year. Germination method: Soak the seeds in warm water at 45 ℃ for 3-4 days, disinfect them with copper sulfate solution, mix well with wet sand, and store them in a low-temperature environment such as a basement. Bury the seeds throughout the second year, remove the seeds in the third year, and sow them when 20-30% of the embryonic roots have germinated. Winter burial germination method: In the autumn of that year, fresh seeds are removed from the seed coat, soaked and disinfected, and buried in wet sand. Planting of Taxus seeds
Soil selection: Taxus chinensis prefers a moist environment and has high requirements for soil moisture. At the same time, the soil should have good drainage to avoid root suffocation caused by water accumulation. Taxus chinensis prefers acidic or slightly acidic soil, and the soil pH value should be between 5, 5~7, and 0.
Sowing time: The best sowing time is usually in autumn, which is beneficial for the seeds to enter dormancy and grow in the following months. If germination treatment is used, the sowing time can be adjusted appropriately according to the germination effect.
Sowing method: Choose a suitable nursery ground, level the bed surface, and irrigate the bed thoroughly. Spread the pre treated seeds evenly on the seedbed, press them tightly with a wooden roller to ensure they are in close contact with the soil, and then cover them with an appropriate amount of river sand or fine soil. matters needing attention
Before sowing, ensure that the soil is rich in nutrients and apply fertilizers as needed.
After sowing, keep the soil moist but avoid waterlogging.
During the growth process of Taxus chinensis seedlings, winter protection measures need to be taken to prevent freezing damage.
Although the seeds of Taxus chinensis can be directly planted, it is recommended to carry out necessary pretreatment and select suitable sowing time and soil conditions to improve germination rate and growth quality.
