Cultivation method of Diansi
Dianhua is favored by horticulture enthusiasts for its elegant flower appearance and medicinal value. Although this perennial herb has strong adaptability, scientific maintenance methods are still needed to achieve the effect of exploding pots. This paper will systematically analyze the six key elements of Dianthus maintenance, from environmental regulation to disease prevention and control. 1. Management of Dianthus growth environment 1. Precise temperature control The optimal growth temperature for Dianthus is 14-18℃, and the overwintering temperature needs to be above 5℃ in winter. Special attention should be paid to the cold wave in spring, and it is recommended to use double sunshade nets for protection. When the temperature exceeds 30℃ in summer, spray cooling measures should be taken and used with a sunshade net with a 50% shading rate. 2. The smart irrigation system adopts a dual mode of "immersion basin + spray" irrigation. Keep the soil moisture at 40%-60% in spring and autumn. Spray it once in the morning and evening every day in summer, and use warm water (about 20℃) to irrigate it thoroughly every 10 days in winter. Note that there must be a 3cm thick ceramsite drainage layer at the bottom of the flower pot. 2. Detailed explanation of Diansi breeding skills 1. Tips for branch propagation The cultivation method of Dianthus chinensis
The best rationing period is in the early morning of March to April, selecting a three-year-old mother plant and retaining 8-10cm of root system. After dividing, the incision was disinfected with plant ash, placed in a scattered light environment for maintenance for 2 weeks, and then transferred to normal management. 2. Advanced sowing technology Spring sowing (March to April) requires germination treatment: soak in warm water at 40 ° C for 6 hours, and place it in an environment of 5 ° C for 24 hours. Autumn sowing (September to October) adopts the (Z-B) method, the sowing depth is controlled at 0.5cm, and the row spacing is maintained at 20cm. 3. Comprehensive pest and disease prevention 1. The root rot prevention and control system is mainly for prevention: use Bacillus subtilis (1:800) to irrigate roots every month. In the early stage of the disease, a combination of hymoxazole + potassium fulvic acid (1:1500) was used, and the effect was enhanced with water cut for 3 days. 2. Green pest prevention and control
