How to raise roots for Clivia seedlings
As a representative of perennial herbs, the root cultivation of Clivia at the seedling stage directly determines the quality of adult plants. Mastering the key points of maintenance during the seedling period can not only avoid the problem of stiff seedlings and yellow leaves, but also allow new leaves to grow quickly at a rate of 1 cm per week. The matrix ratio and disinfection treatment of the five major maintenance systems of Clivia seedlings are based on the ratio of humus soil: garden soil: chaff ash =5:3:2. Add 10g of bone meal per liter of soil to enhance air permeability. Microwave oven killing at high temperature for 3 minutes can kill 98% of the eggs, and it has the best effect after drying for 48 hours. The micro-environment circulation system is constructed to open windows for ventilation from 10:00 to 15:00 every day, and cooperate with a small USB fan to create air circulation. When the hygrometer shows>75%, the dehumidification mode needs to be activated to avoid soft rot caused by accumulated water in the leaf core. The photoperiod control scheme uses a double-layer sunshade net to filter strong light and maintain scattered light of 3000-5000Lux. Turn the flowerpot 15° every 3 days to keep the light evenly received, and adjust the position when the new leaves are obviously bent to the light. Intelligent irrigation mode inserted bamboo stick method to detect humidity, surface layer 2 cm dry when the pot immersion method to supplement water. Addition of 0.02% IBA solution stimulated capillary root proliferation and root volume increased by 40% in two weeks. The temperature control early warning mechanism is equipped with an intelligent temperature controller, which maintains 25±2℃ during the day and no lower than 15℃ at night. The atomization cooling system is turned on during high temperature periods in summer, and a heating pad is used to warm the bottom in winter.
Through the above systematic maintenance, the roots of Clivia seedlings can form a complete absorption network within 60 days. Regularly observe the number of new leaf growth rings. It is a sign of healthy growth that year when the seedlings reach "three leaves and one heart". It is recommended to apply phosphorus and potassium slow-release fertilizers every quarter, and the effect will be better when combined with root activators.
