As a representative of traditional garden flowers in China, Dianhua has become a frequent visitor to the north and south gardens due to its elegant flower appearance and super adaptability. This article will comprehensively analyze this herb, which has both ornamental value and ecological functions, from flowering rules to maintenance details. The core analysis of the geographical distribution and sowing time of the Shizhu flowering period is based on Dianthus japonica, which originated in northeastern China, and is now widely distributed in the Yangtze River Basin, North China and Southeast Asia. Its sowing has dual window periods in spring and autumn: spring sowing can allow flower viewing from September to October of that year, and autumn sowing can bloom from May to June of the following year, providing a cross-year landscape configuration plan for the courtyard. Although the flowering characteristics of a single flower are called "Luoyang flower", the life span of a single flower is only 24 - 48 hours. The flowers of this caryophyllaceae plant have the characteristics of opening and dying, and the overall flowering period needs to be extended through scientific maintenance. Three tips to extend the flowering period of Shizhu, light and temperature control plan 1. Cultivate in a full-sunshine environment and ensure 6 hours of direct light every day. Build awnings in summer and control the temperature ≤ 30 ℃ 3. Water and fertilizer management standards for naturally overwintering above-15 ℃ in winter 1. Adopt the principle of "dry through pouring through", and mix sandy soil with 30% perlite 2. Increase application of phosphorus and potassium fertilizer (N-P-K = 5 - 10 - 10) during the bud stage. Apply compound fertilizers in time after flowering to restore plant vitality and environmental purification. As a natural air purifier, Dianthus can absorb 0.3mg/h of SO ˇ per square meter. It is recommended to mix with evergreen shrubs in contaminated areas at a ratio of 1:5 to form an ecological protection net. Guidelines for year-round maintenance of Dianthus japonica Disease prevention measures 1. Spray mancozeb before the rainy season to prevent rust 2. Keep the plant spacing above 20 cm to ensure ventilation 3. Regularly remove the yellow leaves at the base to reduce the breeding of bacteria, prune and promote flowering.
