Scientific name: Eichhornia crassipes (Mart.) Solms
Family is: Yu Jiuhua, Eichhornia
Alias: water lily, water hyacinth
Perennial perennial herb. Because it floats on the surface of the water, it is also called a water lotus. And because it has a big gourd-like bubble between the root and the leaf, it is also called water hyacinth. Eichhornia crassipes stems and leaves hang on water, and litchi shoots on the water. Flowers are multi-edged trumpet-shaped, bright and beautiful. The leaves are dark green. Leaves whole, smooth and textured. Sorghum is well-developed, fast-growing, and extensive management is a good plant to beautify the environment and purify water quality.
Morphological characteristics: Eichhornia crassipes leaves each leaf with the weight of the leaf flower and is suspended on the surface of the water. The roots must be developed and the roots absorb the nutrients. The main root (flesh root) is the next generation. Leaves solitary, leaves basically lotus leaf-shaped, dimples slightly divaricate, round slightly flat; stem (stem) gray, vesicle slightly red, tender root is white, old root black; flowers are light blue, was more Prismatic horn, yellow spots on the petals, looks like a water hyacinth, and also looks like a flower on the end of the peacock feathers. It is very bright and beautiful.
Ecological habits: Eichhornia crassipes likes to grow on sunny, calm water, or on moist and humid slopes. In the long hours of sunshine, high temperature conditions, rapid growth, by the frozen leaves and stems after the yellow. Every year from the end of April to the beginning of May, germinate on the old roots of the calendar year, and dormant after the frost at the end of the year. The water quality can be as long as 50cm under the condition of suitable water quality, proper temperature, and good ventilation. It can grow to 20cm to 30cm. If floating to the slope of the swamp, the height of the wet shore is only 10cm to 20cm. Eichhornia crassipes sprouts very quickly, and the mother plant grows to 6 to 8 leaves after germinating in mid-spring, and germinate the next generation of new seedlings. First, the young seedling grows two leaves, and then grows the main root (flesh root). As the leaves increase, the main root grows and reaches the water surface that does not affect the mother plant. The stronger growing mother plants can divide 4 to 5 new seedlings at a time, so the breeding is very fast. Eichhornia crassipes blooms in the middle and lower reaches of the Yangtze River from August to October every year, and the flowering period is longer. Each pod spends 4 to 5 days, and the first pod spends 4 to 5 days. After the second pod is opened, two to three pods are opened. A well-grown large stalked flower bud has 15 to 18 flower buds, and at least three or more. When flowering, the average temperature is 25Â°C. It floats on the swamp slopes. It is easy to grow on moist shores and open more than one to two years longer than water. About 5 to 10 flowers per ear.
Cultivation: Bulk cultivation can use wet and scattered or empty swampland behind the houses in front of the house. In June and July, transplant seedlings with strong, low plant height, and reserve 50% of open space. After breeding, they will be born and reared. Appropriate management after transplanting to keep the soil moist, enhance light, and ensure ventilation. If you want to extend the flowering period, you can heat the plastic shed and ventilate it at noon for one or two hours. After the flower buds are formed, they can be transplanted into small pots. Use acidic soil or nutrient solution. The old leaves are removed and leaves 4 to 5 young leaves and flower spikes, which can extend the flowering period and can be moved to the desk and other places for viewing.
Pest control: In conditions with adequate light and ventilation, diseases rarely occur. Low temperatures, poor ventilation, etc., can also occur when pests of the cabbage caterpillars feed on young leaves. A small amount can be caught, and commonly used as a dimethoate emulsion for killing.
