The temperature and temperature control of the greenhouse grape germination directly affects the flowering and fruit setting of the grapes. What measures should be taken to control the temperature and humidity before the germination?

In the shed before the germination of the grape, a 3 to 5 degree stone sulphur mixture should be used to achieve the purpose of killing eggs and germs to prevent future pests and diseases. The temperature in the shed was controlled to about 20 °C one week before the germination period, and then gradually increased to 25-28 °C. During the germination period, the temperature in the shed was kept at 28 °C during the day and the night temperature was maintained at 13-15 °C.

The method of heating up is best to choose a method of heating the air through the pipe in the shed, instead of producing a stove in the shed to avoid excessive carbon dioxide and carbon monoxide, which endangers human safety. Recently, the temperature in the whole province is high. If the temperature in the greenhouse is higher than the standard, the method of covering the straw curtains can be used to cool down, but do not open the shed to prevent the water from escaping and the humidity drop.

In the case of existing irrigated land, the relative humidity in the shed is generally about 80%. This humidity is also the suitable humidity for grape growth before the germination period. After entering the germination period, the humidity will drop to about 70%. During this period, it needs to be done. The guarantee is to keep this humidity constant until the end of the germination period. It should be noted that the wind can not be opened and the humidity is lowered.

In the process of heating up, if the surface temperature can not rise, do not raise the temperature. After the indoor temperature is maintained at 28 °C for a period of time, the surface temperature can gradually rise to the same level, and excessive temperature rise, the temperature will be too high, which will affect the seedling stage. Growing.

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.
