What does the leaves of the other shore flower look like?
As a perennial herb of the Amaryllidae family, the lily has attracted much attention for its unique growth habits and gorgeous flowers. This article will analyze the leaf characteristics from the perspective of professional gardening and provide systematic solutions to the yellow leaf problem to help growers fully grasp the key points of maintenance. Leaf morphological characteristics Seasonal growth regularity The leaves of the other shore flowers follow the special growth cycle of "flowers and leaves never meet each other." The leaves germinate in late autumn from September to November and continue to grow until the end of spring of the following year. This staggered characteristic with the flowering period gave it the nickname "Manjusahua." Anatomical characteristics The leaves are in the shape of a long and narrow band, with a length-to-width ratio of 30:1 (average length of 15cm× 0.5 cm), and the fleshy structure is obvious. The leaf surface is covered with waxy white powder, the cross section is shallow V-shaped, the veins are distributed in parallel, and the entire leaf margin is not serrated. The dark green primary color runs through the pink-green middle rib band, forming a unique two-color texture. Pathological analysis of yellow leaves of Higan Flower is burned by excessive light. When the light intensity is>30000lux and the duration is>4 hours/day, chlorotic patches will appear on the leaves. It is recommended to use 75% sunshade net for regulation, or transplant it to a semi-shaded environment at the forest edge. Imbalanced water management The water-storing properties of the corm make the lily drought-resistant and waterlogging. The soil moisture should be maintained at 40-60%, which can be detected by inserting a bamboo stick method: no soil adhesion is extracted, and the basin bottom needs to be raised immediately if water seeps out. It is recommended to use the ratio of nitrogen, phosphorus and potassium for inappropriate fertilizer application to 1:2:1, and apply organic liquid fertilizer diluted 1000 times every 15 days during the growth period. If fertilizer damage occurs, clean water should be used to continuously leach it three times, and 5cm of surface soil should be replaced. The critical temperature point for overwintering stress due to sudden changes in temperature is 5℃. Below this value, a double-layered plastic shed needs to be built. Sudden temperature differences>10 ° C/24 hours can cause protective yellow leaves, which can be avoided through a gradual environmental transition. For systematic maintenance, it is recommended to choose slightly acidic sandy loam (pH 5.5 -6.5), and the substrate ratio is humus soil: river sand: perlite =5:3:2. Inspect the bulbs every spring when turning the pots, leaving a 3-4cm spacing. Combine biological control (release of predatory mites) to prevent red spiders and ensure healthy leaf growth.
