Scope

I. Basic Conditions Facilities: Intelligent greenhouse (with insulation layer) + air conditioning. Environment for newly planted/repotted plants: Temperature 25-30°C, humidity 70%-90%, and light intensity 6000-8000 Lux. Nutrient growth period: Temperature 25-28°C, humidity 60%-80%, and light intensity increasing from 8000 Lux to 25000 Lux with plant age. Flowering induction period: Temperature 16-25°C, light intensity 25000-30000 Lux. Water quality: pH 5.5-7.0, EC value < 0.4. Varieties: Preferentially select multi-stem, short-stem, and branching varieties. II. Cultivation Management 1. Tissue culture seedling transplantation - Bottle removal: Seedlings without diseases, with 3-5 leaves and 3-5 roots, removed from the bottle in September-November the year before the Lantern Festival. - Hardening: Harden seedlings in an environment of 25-28°C and 4000-6000 Lux for 15-20 days. - Planting: Use sphagnum moss as the substrate and plant in 4.8cm-diameter soft pots, arranging them by size. - Fertilization and irrigation: Start fertilizing 20-25 days after planting with a 20-20-20 fertilizer solution (EC 0.6-0.8mS/cm). In winter and spring, water every 7-10 days; in summer and autumn, water every 3-5 days. 2. Repotting and transplantation - Timing: Repot when the seedlings have two leaves 10-15cm apart and the roots have filled the pot. - Substrate: Choose 1-2 types of sphagnum moss, coconut chunks, or peat, and select corresponding-sized pots. - Fertilization and irrigation: Manage normally for 25-30 days after repotting, using a 20-20-20 fertilizer solution (EC 0.8-1.2mS/cm). Apply a 15-20-25 fertilizer solution once a month to prevent excessive growth. 3. Flowering induction and flowering period management - Before flowering induction: Maintain a temperature of 26-28°C and light intensity of 25000-30000 Lux, and irrigate with 9-45-15 and 10-30-20 fertilizer solutions. - During flowering induction: Maintain a temperature of 16-25°C
