First, winter turn fertilizer
1, winter turn. Through the winter turning can loosen the soil, enhance the permeability of the soil, improve the physical and chemical properties of the soil, create good environmental conditions for the growth of peach; and can effectively control the base number of diseases and insect pests, the young tree can be outside the crown and the vertical position of the crown 1 meter Turn left and right to deepen, expand year by year, to meet. The depth of deep plowing is appropriate to 20-30 cm. The big tree can be combined with basal fertilization to carry out deep plowing in the whole garden. It should be noted that it should be shallow near the trunk and deeper away from the trunk.
2, fertilization. The types of fertilizers are mainly decomposing organic fertilizers with a long-lasting effect, including organic organic fertilizers and self-refining livestock and livestock manure. The amount of fertilization varies depending on the age, growth, and growing conditions, but the amount of basal fertilization should account for more than 60% of the total fertilization for the whole year. The fertilization method is mainly gully application. The depth of the outer surface of the peach tree canopy is 40cm deep and 30cm wide on both sides, and the ditch is formed around the circumference of the crown.
Second, winter pruning
1. Pruning of young trees. The pruning of the juvenile tree is mainly to enlarge the crown, laying a good tree-like foundation for the subsequent high yield. When pruning, according to the requirements of the tree, look at the pruning of the tree, choose, equip and cultivate the main branches and side branches according to local conditions, and properly maintain the auxiliary branches and the resulting branches. At the same time, the angles and growth trends between the main and lateral branches are adjusted in a timely manner so that they can be clearly distinguished and occupied, and each has its own space.
2, fruit tree pruning. After 5-6 years of colonization, peach trees begin to enter fruitful stage. The main tasks of pruning are to maintain the balance of the tree vigor in all parts, adjust the balance of the growth potential of the main and lateral branches, and cultivate and update the branches and branches to prevent premature aging and emptiness in the internal organs.
Third, pest and disease control.
1. Clear Garden. The peach tree branches, peach bags, and scraped old skin that are cut and cut in winter must all be cleared out of Taoyuan and be treated in a centralized manner so as to effectively control the number of pests and diseases.
2, medication. After winter pruning, Baume 5 degrees lime sulfur and 0.3% sodium pentachlorophenol were sprayed to prevent overwintering diseases and insect pests.
3, brush white. Whitening agent with 1 kg of quicklime, water 3-5 kg, 2 tsp of salt dubbed. The preparation method is as follows: first, the quicklime is transferred into a paste, and then a small amount of hot water is used to dissolve the salt and then poured into the water. Then, the water is adjusted to a degree of stickiness that is not a mass and can be easily painted.
Influenza Vaccine, Live, Nasal, Freeze-dried Exclusively authorized by the WHO in China
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
SPF
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
