High yield, high quality and high efficiency technology of tea

The technology is suitable for a modest scale. The tea farmers generally operate 30 mu, adopting clones and improved varieties, put into production in 3 years, and earn 4 to 7 years of high yield in 7-8 years. Integrated production and management, to achieve a production value of 2000 to 8,000 yuan per mu. The main technical points are as follows: (1) The conditions for the selection of sites are 1200 meters below sea level, 25 degrees below the slope, 1,500 mm of annual rainfall, acidic soil (pH 4.0 to 6.5), and deep soil (live soil layer is not lower than 50 cm) Loose, sandy loam suitable. (2) Select 2 to 3 seedlings of good seedlings, good quality, suitable cultivar of elite tea, and large-scale expansion (reconstruction) to plant fine seeds. Also, early, middle and late seedlings and reds should be reasonably allocated. , Green varieties, main cultivars: Fuding Dabai Tea, Fuyun No. 6, Fuxuan No. 9, Mingshan No. 131, Mengshan No. 11, No. 23, Miaoke No. 11 and Early Baijian No. 5. With varieties: Yong Yong Department, Emei Department, Mei Zhan, Qi Ye Qi and so on. Seed height above 25 cm, stem diameter 0.3 cm above, robust and disease-free. (3) Deeply dig planting trenches and apply full-grown planting trenches with a depth of 50 cm or more. Layered fertilization: 5,000 kg/mu of cattle, pig manure and earth miscellaneous fertilizer, 150 kg/mu of vegetable cake fertilizer, and 75–100 kg of phosphate fertilizer / Mu, compound fertilizer 100 kg / mu. (4) The density of plants with reasonable density is 5000-8000 plants/mu; the planting methods are: 2 to 3 plants, with a large row spacing of 120-150 cm and a hole distance of 20-30 cm. (five) post-plant management due to the conditions of the tree, reasonable shape pruning and raising Peng, in order to shape efficient crown. Strengthen soil fertility management, adopt new technologies such as formula fertilization and cover cultivation. In the second three years after planting, famous teas and cuttings can be harvested and put into production in the fourth year and reach high yield in 7-8 years. China Agricultural Network Editor

Hepatitis Virus Tests

Hepatitis is a general term that describes inflammation of the liver. Hepatitis can damage the liver, affect liver function, and over time lead to complications such as cirrhosis, which is severe scarring of the liver, and liver cancer.
There are many types of hepatitis, with both infectious and noninfectious causes. Infectious hepatitis is caused by an infection with a virus, bacteria, fungus, or parasites. The most common type of infectious hepatitis is viral hepatitis, which describes hepatitis caused by an infection with one of several hepatitis viruses. Viral hepatitis includes five main types:
Hepatitis A: Hepatitis A is caused by the hepatitis A virus (HAV). This type of hepatitis is spread easily through contact with stool or blood of an infected person. This can occur through contaminated water and food, sexual contact, or shared intravenous needles. The hepatitis A virus causes acute infections that are often mild, typically resolving without treatment within several weeks. Highly effective vaccines are available to prevent hepatitis A.
Hepatitis B: Hepatitis B is caused by the hepatitis B virus (HBV). Hepatitis B can be spread through contact with an infected person`s blood or certain other body fluids, including transmission from a mother to her baby. This virus can cause either acute or chronic infections. Highly effective hepatitis B vaccination is available to prevent infection.
Hepatitis C: Hepatitis C is caused by the hepatitis C virus (HCV). The hepatitis C virus is spread through exposure to the blood of a person with this infection, often through the use of injectable drugs and during birth to a mother with an HCV infection. This virus can cause both acute and chronic infections. Currently, there is no vaccine to prevent hepatitis C; however, it is treatable.
Hepatitis D: Also known as delta hepatitis, hepatitis D is caused by the hepatitis D virus (HDV). This virus is unique in that it only infects people who already have the hepatitis B virus. HDV is spread through the blood or other body fluid of an infected person, most often from sharing needles and unprotected sex with a person who has this infection. Hepatitis D can be either acute or chronic. The vaccine for hepatitis B can prevent hepatitis D because only those infected with hepatitis B can contract HDV.

Hepatitis E: Hepatitis E is caused by the hepatitis E virus (HEV). Hepatitis E is spread through ingesting small amounts of the virus, often through drinking contaminated water and from animals to people when consuming undercooked foods like pork or wild game. HEV causes an acute infection that doesn`t require treatment.
