1, morphological characteristics: erect stems, dark green leaves, symmetrical plant shape, long linear leaves, 30-40 cm long and 5- 10 cm wide. Umbellies are arranged in general, with small flowers, yellow-green, fragrant, flowering from June to August, and berries are spherical. Old leaves are naturally strong and have strong adaptability to light and red. They will be darker and greener in weak light, and can be placed in indoor light for 6 months to 2 years. It is the most shade-tolerant ornamental plant among indoor green plants.
2. Cultivation points The cultivation medium should be fertile loam or humus with good drainage. 50-60% shading is the best illumination, and direct glare is not allowed. Indoor cultivation should be placed in a well-lit place. Insufficient light will make the leaves fade, and the leaves are slender and wavy. Fertilization can use organic fertilizer, such as rotten peanut bran or human feces as fertilizer, and can be combined with ternary foliar fertilizer, 3-4 times a month. Sex likes high temperature and high humidity, and the suitable growth temperature is 20-35℃. Winter in 10℃ should pay attention to cold protection measures, to prevent freezing damage to dry up the leaves. Pay attention to ventilation and keep the relative humidity of air above 80%.
3. Changing pots and plastic pipes Every spring is the best time to change pots. When the plant shape is large enough, it is advisable to change the big pot to make the roots have more room for growth. Dracaena plants are resistant to pruning. As long as the top or upper branches are cut off, the buds below the incision will germinate and grow into new branches, which can grow 1-5 buds at the same time, enriching the crown width, making the plant shape more symmetrical and increasing the beauty of the plant shape. Many growers often cut off the tops when the plants grow to 1 m high. After half a year to a year, the price of plants can be increased by 3-4 times, which is a typical flower deep processing process.
4. The propagation method is mainly tissue culture, and cutting propagation can also be used. The seedlings cultivated by tissue culture and propagation are neat and stable.
5. The common phenomena in pest control are scorched leaves and scorched edges. This is a physiological disease caused by dry air or irregular watering and fertilization after drought or low temperature, which can only be overcome by strengthening daily management.
