In the process of planting Dahlia Pinnate CV, the dry seeds should be removed first and then soaked in warm water to accelerate germination. The selected culture soil is mainly a mixture of vegetable garden soil, furnace slag and peat soil. After being planted, the soil should be watered thoroughly, covered with wet grass and sand, and the temperature should be controlled above 15℃.
Dahlias are one of the top 10 most beautiful flowers in the world
When planting dahlia pinnate CV, the selected seeds should be rinsed once in clear water.The sunken seeds should be used as cultivation materials, and then soaked in warm water at 40℃ for 3-5 hours. The seeds should be thoroughly disinfected after water absorption and expansion, and then air-dried in a ventilated environment.
The soil planted is an important condition for planting Dahlia Pinnate CV seeds. The selected soil is mainly a mixture of vegetable garden soil, furnace slag and peat soil. When it is loaded into the soil, a 2cm thick coarse sand matrix can be placed at the bottom of the basin as a water filter layer, and a layer of decayed organic fertilizer particles can be sprinkled on it as a base fertilizer.
Before planting, an appropriate amount of polymycorrine or potassium permanganate solution can be applied to the basin soil to play the role of disinfection and sterilization. After the dried seeds are buried in the soil, they are poured into an appropriate amount of water and mixed evenly, covered with a layer of sand and straw, and the temperature is controlled above 15℃ for germination and rooting in about one month.
When the seed seedling grows to 10 cm, transplanting treatment should be carried out. After transplanting, water should be poured through once, and it should be maintained in a shaded environment for a week. After growth recovery, it should be placed in a sunny environment, and proper loose soil treatment should be carried out each time watering to promote the normal growth of the root system.
