Appearance characteristics and variety introduction of variable leaf wood? In daily life, many people keep some plants at home, but there are many kinds of plants on the market. Someone wants to know the information about alternifolia. Let me share the morphological characteristics and variety introduction of variable leaf wood. Let's have a look.
Appearance characteristics and variety introduction of variable leaf wood 1
Variable leaf wood
Deciduous trees are evergreen shrubs or small trees. Height1-2m. Simple leaves alternate, thick leathery; The shape and color of leaves vary greatly according to different varieties. The shape of leaves is linear, lanceolate to oval, whole or split, wavy or spiral twisted, which is very strange. There are often white, purple, yellow and red patches and lines on the leaves, and the whole plant has milky white liquid. Racemes are born in the axils of upper leaves, and the flowers are white and inconspicuous. Common varieties are: long leaves, lanceolate leaves and yellow stripes on green leaves; Angle blade type, the blade is slender, and the tip of the blade is tilted; Spiral, wavy, irregularly twisted and coiled, copper-green leaves, red midvein and yellow spots; Thin leaf type, strip shape, only110 of leaf length, extremely slender, dark green, with yellow spots on it; Broad-leaved, ovoid or obovate, dark green with bright yellow spots.
Branches are hairless with obvious leaf scars. Leaves are thin and tough, and their shapes and sizes vary greatly. They are linear, linear, lanceolate, rectangular, oval, lanceolate, ovoid, spoon-shaped, violin-shaped to obovate, and sometimes the leaves are divided into upper and lower pieces by a long midvein. 5-30 cm long, 0.5-8 cm wide, short-pointed, tapering to blunt, wedge-shaped at the base, short-pointed to blunt, full-edged, shallow-split to deep-split, with no hair on both sides, green, light green, purplish red, purplish red and yellow, yellow-green or sometimes scattered with yellow or golden spots or stripes on the green leaves; The petiole is 0.2-2.5 cm long. Racemes axillary, monoecious, 8-30 cm long, male flowers: white, 5 sepals; 5 petals, much smaller than sepals; 5 glands; 20-30 stamens; Pedicel slender; Female flower: pale yellow, sepals ovoid triangle; No petals; Disk ring; Ovary 3-loculed, flowers bent outward, undivided; Pedicel slightly thicker. Capsule subglobose, slightly flat, glabrous, about 9 mm in diameter; The seeds are about 6 mm long. Flowering: September -65438+ 10.
Brief introduction of appearance characteristics and varieties of variable leaf wood 2 How to prevent variable leaf wood from falling leaves
First, the temperature is too low. Variable leaf trees shelter from the cold. When the temperature is lower than 18℃, they will shed their leaves. When the temperature is lower than 10℃, the top leaves will wither and droop.
Second, the light is too strong. Strong direct light in summer will not only make the leaves pale, but also lead to falling leaves.
Third, the water supply is insufficient. Changing trees to avoid drought requires a lot of water, so watering should be based on the principle of wet rather than dry. Once the soil in the basin is dry, plants often lose their leaves due to lack of water. In addition, attention should be paid to spraying water on the leaves and the surrounding ground frequently to maintain a humid environment.
Fourth, improper pruning. People often do not pay attention to the pruning and pruning of flowers. In fact, this is very important for most flowers, and the pruned plants will be more lush.
Fifth, fertilization. In the vigorous growth period, more nitrogen-containing substances should be applied, for example, the "foliage plant flower fertilizer" on the market at present can be used.
6. Poor ventilation and drainage. Put deciduous trees in a well-ventilated place indoors, otherwise the harm of scale insects and red spiders may occur. The basin soil is composed of peat soil and coarse sand to ensure good drainage. Variable-leaf tree species have low requirements for soil pH value.
