How to reproduce colored calla lilies
Colored calla lilies have become the darling of the horticulture world because of their colorful colors. Mastering the correct reproduction techniques can allow the plants to continue to reproduce and grow. This article systematically explains the operating points of the two mainstream breeding methods, and combines them with real-shot illustrations to allow you to easily master the secret of expanding colorful calla lily. The core technology of colorful calla lily reproduction is the most commonly used method for breeding colorful calla lily. It is recommended to operate in spring and autumn (temperature 20-25℃), when the plant is in an active growth period. When excavating tubers, it is necessary to keep the root system intact. Use a disinfectant knife to divide the cue ball into 2-3 clusters, each cluster with more than 3 bud points. Apply the incision with plant ash immediately after cutting. After the wound is dried, plant it in slightly acidic humus soil respectively. The depth of soil covering should be 2 cm from the bud point to the soil surface. Advanced Skills for Seed Breeding Ball Breeding is suitable for large-scale production. Strong balls with a diameter of>3cm are needed. The best operation time is the autumn dormant period, using high-ridge cultivation method, and keeping the row spacing at 20cm×15cm. When planting, the bud points face upwards, cover with a soil thickness of 2-3cm, and then pour thoroughly with root-fixing water. It should be noted that the bulbs are mainly cultivated in the first two years, and can only bloom normally in the third year. During this period, phosphorus and potassium fertilizer are applied monthly to promote the bulb expansion. Key points of breeding management: Environmental control standards: Maintaining the day temperature of 22-25℃/night temperature of 16-18℃ is most conducive to the growth of new plants, and the air humidity needs to be maintained at 60-70%. The light intensity is controlled at 20,000 - 30,000 lux, and 40% of the sun needs to be shaded during the strong light season. The humidity of the substrate is kept "moist but not wet," and the dipping basin method is used to replenish water to avoid rot of the seed balls. Disease prevention measures After dividing, spray 50% carbendazim 800 times solution every week to prevent soft rot for three consecutive weeks. When the initial symptoms of leaf spot disease are found, the affected leaves are removed in time and sprayed on the whole plant with 600 times solution of mancozeb. Regularly check underground pests such as grub, and bury tea cake powder for biological control.
Through scientific ball cutting and rationing, standardized ball breeding, and meticulous environmental management, the success rate of colorful calla lily breeding can be increased to more than 90%. It is recommended to give priority to the rationing method in home gardening, and professional growers can combine the two methods to achieve efficient expansion. No matter what method is used, remember to do a good job in disinfection and early maintenance to get strong new plants.
