Rare Dahlia Flower Seeds 100 Seeds Planting Dahlia Seeds 3

Seed reproduction occupies a large proportion in the cultivation process of dahlias and is suitable for varieties that are easy to bear. Generally, the seeds harvested in autumn are sown between February and March of the following year at 15-20°C during the day and no lower than 12°C at night. The seedlings reproduced from the seeds are full of vitality, healthy growth and development, and strong adaptability. A large number of plants can be obtained in a short time, but the flowering and fruiting are slow. The flowering period is late, and the excellent characteristics of the female parent cannot be maintained, and there is degradation. Sowing method (1) Sowing time Wash the sterilized seedling tray with clean water before planting. Seed immediately after the water seeps. Hotbeds are sown in the middle and late March, and flowerbed varieties are sown in the open field in late April, and the seeds are sown on the soil. The large seeds are covered with moist, fine soil after sowing, and the thickness is 3 times the seed diameter. After sowing, use bamboo poles to support the agricultural film, leaving gaps for ventilation, which is beneficial to increase soil temperature, reduce water content, maintain soil moisture, and reduce soil compaction, so as to maintain the temperature and humidity required for seed germination. After sowing, put it at 20~25?. After about 7 days after sowing, the seeds can germinate. Keep the soil moisture frequently. Divide the seedlings when they grow to 4~5 cm, water them thoroughly, and place them in the shade for 3~4 Day, then move to strong light, pay attention to timely watering, to maintain soil moisture. (2) Post-broadcast management Water according to soil moisture. Keep the soil wet between dry and dry. When the surface of the soil is slightly dry, moisturize it by dipping. The suitable temperature for seed germination is 19~21?. Frequent ventilation after sowing is conducive to seed germination. Dahlia se
