The growth process of Clivia
Do you often encounter clivia only long leaves do not bloom the situation? This ornamental plant, known as the "rich flower," contains a unique life code during its growth process. From seed germination to bloom, each stage requires a corresponding conservation strategy, and we will reveal the secrets of its growth through four key growth stages. Seed treatment and sowing techniques during sowing and germination stage Mature seeds need to be soaked in warm water at 40 ° C for 24 hours to activate vitality. The sowing depth should be 0.5 cm. It is recommended to use peat soil mixed with perlite (3:1) as the substrate to maintain a constant temperature environment of 22-25℃. During the seedling period, the environmental control humidity needs to be stabilized at 70%-80%, and atomizing spraying methods should be used to replenish water. The light intensity should be controlled at 3,000 - 5,000 lux, and the scattered light exposure should not exceed 3 hours per day. Characteristics of leaf bank formation during the critical period of leaf development The bowl-like leaf bank structure appears around the 45th day. At this time, special attention should be paid to avoid water accumulation. It is recommended to place absorbent cotton sheets in leaf axils and replace them regularly to prevent mildew. Real leaf growth regularity The first real leaf is oval leathery, and subsequent leaves grow in a spiral arrangement. Add decomposed soybean cake water once a month, and maintain the ratio of nitrogen, phosphorus and potassium at 3:1:2. Flowering regulation and management Conditions for flower bud differentiation When 12 functional leaves are fully unfolded, the reproductive growth period enters. The temperature difference between day and night needs to be ≥8℃, and controlling the night temperature at 15-18℃ for 30 days can effectively promote flowering. Flower maintenance technology at full flowering stage ensures uniform light reception at 45 degrees per pot. Application of potassium dihydrogen phosphate (concentration 0.2%) can extend the flowering stage by 5-8 days. The air circulation volume needs to be maintained at 0.3-0.5m/s to avoid buds falling. The physiological characteristics of dormancy maintenance change in summer. When the temperature exceeds 30℃, it enters a semi-dormant state, and the metabolic rate decreases by 60%. The waxy layer of leaves thickens and the stomatal opening decreases to 1/3 of that during the active period. Special management measures use the potted pot method for thermal insulation, and the gap between the outer pottery pot and the planting pot is filled with vermiculite. Pour 200ml of cold white boiled water along the wall of the basin every 15 days, and use spray on the back of the leaves to cool down.
By observing four typical stages of the growth cycle of Clivia, we found that temperature gradient and light management are key factors affecting flowering. By regularly recording the leaf growth rate (ideal monthly growth of 2- 3 cm), adjusting the fertilizer ratio, and adopting differentiated management based on seasonal changes, this "gentleman in flowers" can bloom year after year.
