Summer temperatures are high, often encounter drought, tea tree roots are limited by water conditions, weak absorption capacity, poor root fertigation effect. If foliar fertilizer is applied during the growth of summer tea, not only the tea yield can be increased, but also the tenderness of new shoots can be enhanced and the quality of summer tea can be improved. Tests have shown that spraying leaves of tea leaves can increase tea production by about 10%. The specific method is:
1, with urea 0.5-1%, ammonium sulfate 1%, superphosphate 1-2%, potassium sulfate 0.5-1%.
2. The application time is prosperous with new shoots. The cloudy days when 1 bud and 1-2 leaves are unfolded are good in the evening or in the morning. Each time, 5-100 kg of fertilizer solution is used per acre, spraying once every 3-6 days. When spraying, both front and back sides must be sprayed at the same time, especially the back of the leaves must be sprayed.
3, spraying process to avoid high-temperature exposure, cause water evaporation and change the concentration of fertilizer, but also to prevent fertilizer from being washed in the rainy days.
4. At the same time when foliar fertilizer is sprayed, it is still necessary to strengthen the top dressing of the tea tree roots in order to achieve mutual promotion.
Influenza Vaccine
Influenza Vaccine, Live, Nasal, Freeze-dried Exclusively authorized by the WHO in China WHO
Influenza Vaccine, Live, Nasal, Freeze-dried is a cooperative project with the WHO, which has been included in Global Action Plan for Influenza Vaccines (GAP)[1]. Hundreds of millions of doses have been used in the world, and Changchun BCHT Biotechnology Co. has the exclusive right of production and
operation in China.
Intranasal spray administration, no injection and no pain
The vaccine is inoculated by nasal spray, equipped with nasal spray device, and only needs to spray once a year in two nostrils to prevent influenza.
Mucosal immunity + Cellular immunity + Humoral immunity
After influenza virus attacks human body, it widely exists in nasal cavity, respiratory tract and other mucosal parts, as well as in body fluids and cells.
Vaccination of Influenza Vaccine, Live, Nasal, Freeze-dried can quickly stimulate the triple immune response of human body, and carry out defense
against viruses in different parts:
·Intranasal administration can produce mucosal immunity (IgA antibody), which forms the first immune defense line in the nasal cavity.
·Produce humoral immunity (IgG antibody) to remove influenza virus from body fluids.
·Produce cellular immunity (T cells) to remove influenza virus from cells
3+N More extensive protection
The production strains are recommended and supplied by the WHO every year.
The vaccine can not only effectively resist the vaccine strain, but also produce cross immunity to other subtypes of influenza virus.
Produced with SPF embryonated eggs
The chick embryos for vaccine production comes from SPF (specific pathogen free) chicken flocks, so the risk of exogenous pathogenic microorganism
pollution is excluded.
Free of inactivator, split agent and preservative
High protection and fast antibody production
This is the first influenza vaccine in China that has been evaluated by the protection effect of etiology in clinical stage. The protective effect of phase III
clinical trial is consistent with the literature[2]
.
First, the immune barrier was formed in the nasal mucosa after LAIV vaccination. It has been reported that the antibody of nasal mucosa can be
produced in 3 days[3], which greatly shortens the time for vaccine to produce
protective effect.
