Natural water hyacinth

Standard

Floating plant. Root was born in festival, developed root system, by Mao Gen root ( root absorption of nutrients, meat ) tiller next generation. Leaf blade ovate to Dan Sheng, upright, rounded at the top of kidney, slightly concave, smooth; Ye Bing at the vesicle to assume Ye Hua’s weight in water, suspended growth. Straw ( stem ) gray, vesicles with red root roots, tender white, partial black. Spikelike inflorescence, flower is pale blue, a multiple edge horn, at the top of the petals larger; petals center had a clear bright yellow spots, like water, like the peacock Yu Ling tail spots, very bright, beautiful. Capsule ovoid, there are many seeds.

Ecological habits

Water hyacinth loves in Sunningdale, calm water, or moist and fertile slope growth. In the long hours of sunshine, temperature under conditions of high growth is rapidder, the frozen stem yellow. Every year at the end of 4 to early 5 in the calendar year of the roots on the germination, to the end of the year after the frost dormancy. In the water quality compliance, temperature appropriate, better ventilation condition from Gao Kechang to 50cm, the general can grow to 20cm ~ 30cm, such as floating to the swamps of the slopes, moist bank height only 10cm ~ 20cm. Water hyacinth off very quickly, with the plant after germination to a length of 6 to 8 leaves begin the next generation bud germination. The first is the seedlings grow out of two leaves, followed by a long taproot ( meat root ), with the leaves increased, root growth, does not affect the water extends to plant growth. Growth and stronger plant a tiller 4 ~ 5 seedlings, thus reproduce very quickly. Water hyacinth in middle and lower reaches of Yangtze River every year from August to October, blossom, longer florescence. Each flower 4 to 5 days after the first stubble, Xie Hou spent 4 to 5 days, the line also opened second stubble flowers, a total of two to three. Growth of large good stalk spikes of flowers with 15 to 18 flower buds, at least three flower above. Blossom when the average temperature of 25 degrees C, drifting in the marsh shore slope, wet growth is extremely easy to blossom, a more open than the water in one to two years. Each spike is about 5 ~ 10 flowers. Happy high temperature and humid climate. General 25-35 C for the growth and development of most suitable temperature. More than 39 DEG C inhibits growth. 7-10 C in a dormant state; more than 10 DEG C began to sprout, but the deep autumn I arrived after the frost, wither soon. Alkali resistance, pH value of 9 is still the normal growth. Disease resistance is strong. Extremely resistant fertilizer, good group of students. But in many storms on the surface, then the growth of undesirable. Florescence is long, from summer to autumn blossom on.

But in many storms on the surface, then the growth of undesirable. Florescence is long, from summer to autumn blossom on. Contribution to the study of water hyacinth literature shows, in addition to being garbage percolation sewage poisoning death of individual reports, water hyacinth in almost any sewage grow well, fertile. Not only that, it can enrichment of various pollutants: from the life of organic pollutants in wastewater, industrial wastewater, rare earth elements, to the farmland into pesticide contaminants, water hyacinth is almost refuse nobody, one one to absorb. It is almost a perfect water purifier, in addition to a drawback: it will only be responsible for pollutants collected, but not responsible for all pollutants degradation. The toxin remains, merely shift location. Water hyacinth on the life water taken savage blockade strategy, block the sunlight, leading to water plants can not get enough light and death, destruction of water under the animal food chain, leading to the death of aquatic animals. At the same time, any size vessels also don’t want in water hyacinth in the free territory. Not only that, water hyacinth and heavy metals enrichment capacity, water hyacinth dies decay body sinking to the bottom form a heavy metal of high content layer, direct destruction of benthic organisms. It is a three-in-one type extermination tactics!
