Litsea cubea [Listeacubeba (Lout.) pers. ] The chicken pepper, mainly distributed in eastern Asia, Oceania and the Pacific islands. It is mainly distributed in Guangxi, Guangdong, Fujian, Zhejiang, Jiangsu, Jiangxi, Hunan, Hubei, Yunnan, Sichuan and other provinces south of the Yangtze River. Most of them are located on the margins of gentle slopes, hilly shrubbery lands and sparsely forested lands. In particular, the firewood of Chinese fir plantation grows most. Hunan Province is one of the main producing areas of Ligonegus sylvestris. Besides the few county seats in the Dongting Lake, the rest of the mountainous areas and hilly areas are distributed, mainly in the wild. At present, some of China's provinces and autonomous regions have been artificially cultivated, with Fujian, Sichuan and other provinces having the largest cultivated area. Litsea cubeba extracts aromatic oils regardless of fruit, leaves, flowers and root bark. After the fruit matures, it can be obtained by steam distillation to obtain a light yellow transparent volatile aromatic oil, commonly known as Litsea cubeba oil. Each 50kg of Lithocarpus fruit can be oiled 2~3.5kg. It is an important raw material for the extraction of citral, and citral is the main raw material for the production of specialty flavors, ionone, methyl ionone and vitamin A for the cosmetic crystal, food and pharmaceutical industries. The fruit of Lithocarpus can also be used as a Chinese medicine, which has the effect of qi dilatation, hernia spasm, and vomiting. Litsea cubeba fruits can be used to make soap and machine lubricants after distilling volatile oil. It can also be used to produce 15% to 25% of fixed oil. The oil residue is rich in organic matter and can be used as fertilizer. There are three main artificial cultivation methods for Litsea cubeba. 1 Live Afforestation The fruits of Litsea cubeba ripen from January to August. The skin of the fruit is reddish-brown and with wrinkles. Seeds are sowed immediately. If 3 to 5 days after sowing can not be sown on time, combined with germination best wet sand storage. The planting holes are 50cm in length and 13cm in depth, 6-8 seeds per hole, 2cm soil cover, and covering. From the third to the fourth April of the second year, the first weeding, ripping, and thinning were carried out after half a month. The height of the seedlings was about 1m, and cultivating and cultivating were continued. 2 Transplanting seedlings generally uses wild seedlings for transplanting, and a small amount of fertile seedlings for transplanting. From March to April, the choice of afforestation of wild seedlings when the soil was wet was cloudy or sunny on a sunny day. The survival rate was 95%. It is required to dig up wild mountain caspang seedlings that are 1 to 2 years old, about thick fingers, and free from pests and diseases. Don't hurt too much when digging, it is better to bring home soil, seedling height 50 ~ 80cm, with the digging with the transport along with planting. When planting, do root extension, soil compaction, and planting. Plants and row spacing of 11m are appropriate. Every 3 to 5 rows can be planted with 1 row of male plants to pollinate trees, and the arrangement method of 1 male plant from a certain number of mother plants can also be adopted to increase the seed setting rate. If mixed in Chinese fir, Camellia oleifera and other forests, it should not affect the growth of Chinese fir and Camellia. 3 It is a simple and easy method to artificially promote the regeneration of natural Litsea cubeba forest. The method is to strengthen the artificial tending management in the more concentrated and well-characterized wild Ligona chinensis or mixed forest, and to eliminate Density, fill in the blanks, and adjust the density of forests to make it a highly productive Litsea cubeba forest. For wild Ligustus sylvestris forest land with poor robustness, senescence, or uneven distribution, the weeds and shrubs in the woodland can be cut off after the maturity of Litsea cubeba from March to April or July to August. The seed of Ligona officinalis is turned into the soil, and after emergence, after 2 to 3 years of tending management, the young Litsea cubeba reaches an average height of 3 to 4 m, making it a highly productive Litsea cubeba forest. Litsea cubeba fruit must be timely harvested. When the skin of the fruit is cyan with white spots, shiny, no wrinkles, a strong ginger odor when the skin is crushed with a finger, the nucleus is hard, the nucleolus is light red and with a slight amount of slurry is the most suitable harvest. Fruit citral content and oil yield at this time are the highest. It is imperative that the fruit should be harvested at the same time. When harvesting, do not injure the tree. The seeds must not be piled or piled after harvesting. They must be processed and processed in time because the yield of fresh fruit is more than twice as high as that of dried fruit.
Seafood is consumed all over the world, it
provides the world's prime source of high-quality protein: 14–16% of the
animal protein consumed worldwide; over one billion people rely on seafood as
their primary source of animal protein. The nutrients and minerals in seafood
can make improvements in brain development and reproduction and has highlighted
the role for seafood in the functions of the human body. Seafood mix has been
shown to help the symptoms of rheumatoid arthritis – a painful
condition that causes joints to swell up, reducing strength and mobility.
