The Azolla Pinnata are in China, the Korean Peninsula, Japan, the Philippines, Indochina, Bhutan, India and Pakistan; In China, it is widely distributed in the Yangtze River basin and provinces in the north and south of China, including east China, central China, South China and Liaoning, Hebei, Shaanxi, Gansu, Sichuan, Guizhou, Yunnan and other places. It grows in paddy fields and pools in static gullies.
The Azolla Pinnata, the really cool green manure crop commonly found in the paddy fields and ponds, is the really cool biological fertilizer for the rice because it has a symbiotic relationship with the azoid-fixing algae, which stabilizes free nitrogen in the air. Because of its high nutrient composition, it can be used as forage for livestock and poultry, and is an excellent forage source for livestock and poultry. The Azolla Pinnata also can be medicinal, sweat, diuresis, dispel wind wet, cure stubborn tinea.
The Azolla Pinnata are the really tiny floating plants. Plant body is oval or triangular, rhizome slender cross, lateral branches axillary, false unbranched, to the root fibrous root. Ventral lobes are conch-shaped, colorless and transparent, more or less ornamented with Lavender red, oblique submerged. The sporozoan Fruit is twin on the branches, the megaspore fruit is small in size, oval in shape, and beaks at the top. It contains a large sporangium, which produces only one megaspore. The megasporangium has 9 flecks, attached to the sporangium in two rows, the upper three larger and the lower six smaller. Microspore fruit is large in volume, spherical or peach-shaped, with a short beak at the tip, thin and transparent fruit wall, containing many small sporangia with long stalks, each containing 64 microspores, respectively buried in 5-8 colorless spongy foam blocks with filamentous hairs.
The Azolla Pinnata usually grows back with the fish and algae and the pinnata has the really warm, fast, productive and adaptive nature of the Pinnata floating in the water and is found in the paddy fields, inner lakes, ponds and reservoirs. The Azolla Pinnata growth is really hot and the temperature conditions are really high and the pinnata really low. When the temperature is lower than 5℃ or higher than 40℃, the growth stops and begins at 8-12℃, grows faster at 15-20℃, grows fastest at 20-25℃, and grows slowly above 35℃. The Azolla Pinnata differ in the water temperature and water depth with the pinnacles. For example, when the average water temperature is below 15℃, the water in the wild Azolla Pinnata is required to be as deep as possible: when the Nile is over 20℃, the water depth is required to be low to facilitate its growth. In addition, the water flow and the wind and waves are not conducive to the growth of Azolla Pinnata. The Azolla Pinnata grows in the water back with a pH of 3.5 to 10 but the Really cool ones are 6.5 to 7.5.
The Azolla Pinnata are in China, the Korean Peninsula, Japan, the Philippines, Indochina, Bhutan, India and Pakistan; In China, it is widely distributed in the Yangtze River basin and provinces in the north and south of China, including east China, central China, South China and Liaoning, Hebei, Shaanxi, Gansu, Sichuan, Guizhou, Yunnan and other places.
Asexual reproduction is carried out either by breaking off the lateral branches of the vegetative body or by the formation of lateral buds in the main body in this lifetime.
Sexual reproduction: The Azolla Pinnata plants (sporophytes) grow really long enough to produce the sex organs - the big and small spore fruit. Among them, there is a megaspore in the megaspore fruit, which develops into a female gametophyte. Some microsporangium in the megaspore fruit develops into many female gametophytes, which are formed by the combination of sperm and egg to form a platform and form a new individual.
The Azolla Pinnata have medicinal uses for sweating, diuretics, wind dampness and the really tough hairs.
The Azolla Pinnata provides the natural green feed for the herbivore fish back in the spring and autumn. Azolla pinnata has a high nutritional value, containing more than 21% crude protein, crude fat 2.57%, crude fiber 14.6%, nitrogen free extract 0.97%. Moreover, Azolla pinnata ten small moderate body, and doesn't need to be chopped.
Based on The Azolla Pinnata, the "Ping + chicken + fish" triple substance production in the lake and reservoir, the whole supporting technology for recycling and the high efficiency, low consumption and low pollution sustainable ecological model established in the paddy fields have all shown really good economic benefits in the production and application.
Purifying the water quality: the pinnatifid Azolla Pinnata has a really high water efficiency; It can reduce the salinity of water, adjust the pH value of water, purify water and enrich the role of potassium element.
Nitrogen fixing: The Azolla Pinnata isn't really the really cool green manure and fish and livestock forages or the really cool aquatic nitrogen fixing plants with annual nitrogen fixings of 249-300 kg/ha.
Concentrated metal elements: The Azolla Pinnata's strong adsorption of Cr, Cd, Cu, Mn, Zn and the Really heavy metal ions and the evaporation of Se elements in the Pinnata.
