Pueraria, a genus of the genus Rhododendron, has a feathery shape and 3 leaves. At present, there are about 14 kinds of puerarin grown in China. Commonly, there are kudzu, edible puerarin, pueraria pueraria, eucalyptus radix radicans, radix radicans, genus Pueraria lobata, and genus Trichosanthes. It is mainly distributed in southern China and southern China. Pueraria's roots are thick, not only edible, but also have good health care benefits. In some ancient Chinese medical books, Kudzu’s is described as follows: “Sexual sweetness, Xin, Ping, clearing heat, rash, thirst, and diarrheaâ€. With the continuous advancement of science and technology, people have realized that Pueraria is rich in starch, isoflavones, and trace elements such as calcium, selenium and iron, which are essential for human body. The value of Pueraria is constantly being exploited and utilized. The Pueraria products are on the market, and the economic benefits of planting Pueraria are increasing.
Biological characteristics
Pueraria's ecological adaptability is very strong. Except for saline-alkali land and low-lying water, it can grow. The rest, such as grass slopes, roadsides and fields, can grow regardless of fertility. Pueraria's growth has no strict requirements on altitude. It usually grows on sunny slopes, flats, hills, low mountains, or high mountains below 1,700 meters above sea level, but prefers deep and loose soil environment. Pueraria is very resistant to cold, heat and drought, but it is not resistant to cockroaches and prefers to grow in warm and humid climates. Pueraria lobata generally undergoes 240 to 300 days from cutting seedlings to roots. It can be divided into two growth stages. The early stage is the stem and leaf growth stage, and the later stage is the simultaneous growth of stem and leaf growth and root formation. The temperature of the stem and leaf growth period is 20~30°C, and below 15°C, the puerarin will grow poorly: the most suitable temperature for the root formation period is 25~30°C; the temperature of starch transformation and accumulation period of the root is 15~ 20 ° C is appropriate.
The growth of Pueraria requires good light, especially when the stems and leaves are growing at the same time. The sufficient light and temperature can make the stems and leaves grow rapidly, the photosynthesis products are more, and the roots are well developed.
