Scope

Main Technical Content: 4. Production Technical Requirements 4.1 The varieties should be locally improved and cultivated cyclamen varieties. 4.2 Seedling Production 4.2.1 Seed selection: Select flower-shaped seeds according to product requirements, and the seed quality shall comply with GB/T 18247.4. 4.2.2 Sowing time: Determine based on the time of harvesting finished products. 4.2.3 Sowing method: Manual or machine sowing can be used. Seeds are sown into trays with 288 or 200 holes each, one seed per hole, and covered with vermiculite at a thickness of one seed diameter. 4.2.4 Germination promotion 4.2.5 Seedling management 4.2.5.1 Strengthen greenhouse temperature, humidity, and lighting management until the cotyledons unfold and the first true leaf forms. 4.2.5.2 Based on seedling emergence, apply high-potassium fertilizer as the main fertilizer. When the substrate moisture level reaches level 3, water directly. 4.2.6 Transplanted seedling management 4.2.6.1 Maintain appropriate greenhouse temperature and humidity and enhance lighting intensity until the fourth true leaf forms. 4.2.6.2 Based on flower seedling growth, apply high-potassium fertilizer as the main fertilizer and alternately use high-nitrogen fertilizer at a ratio of 3:1. Water directly when the substrate moisture level reaches level 2. 4.2.7 Hardening seedlings 4.2.7.1 Start hardening seedlings when they have four or more true leaves. Reduce greenhouse temperature and humidity and maintain strong lighting. 4.2.7.2 Implement fertilizer and water management in the later stages of transplantation. 4.2.8 Transplantation into pots 4.2.8.1 Transplant flower seedlings into trays with 72 or 50 holes each after hardening. After transplantation, expose 1/2–1/3 of the bulbs above the substrate surface. Transplant into pots after 4 weeks. 4.2.8.2 Based on flower seedling growth, apply high-potassium fertilizer as the main fertilizer and alternately use high-nitrogen fertil
