Vaccine For Prevention Of Rabies Rabies vaccine is used in two ways. Rabies vaccine is given to persons who have been exposed (eg, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies vaccine may also be given ahead of time to persons who have a high risk of getting infected with rabies virus. These persons include veterinarians, animal handlers, or travelers who will spend more than 1 month in countries having a high rate of rabies infection, and persons who live, work, or take vacations in wild areas of the country where they are likely to come into contact with wild animals Vaccine For Prevention Of Rabies,Human Rabies Vaccine Adjuvant,Human Rabies Shot Procedure,Rabies Immunity After Vaccination Changchun Zhuoyi Biological Co., Ltd , https://www.zyvaccine.com
Garden cherry commonly used pruning method
1, short cut. Cut a part of the one-year-old branch that is a short cut. According to the different degree of short cut, can be divided into light and short cut, short cut, heavy short cut and extremely heavy short cut. (1) Light and short cuts. That is, the cut length is less than 1/3 of the total length of the shoot. In saplings, lighter and shorter cuts are used, which can ease the growth potential and facilitate early results. The initial result tree is light and short, which is conducive to both growth and results. Mature trees, in order to ease the growth potential of strong branches and increase the amount of short branches, light and short cuts can also be used. Strong branching varieties, such as purple, early purple, etc., often use light and short cut, uniaxial extension of the results of training branches. (2) Short cuts. That is, cut 1/3--1/2 of the shoots. When saplings are reshaped, short cuts are made on the extension branches and peripheral branches of the stem branches. Generally, 3 to 5 medium and long branches and 5 to 6 leaf branches can be obtained. In the mid-short section of the internal meandering branch, it is generally possible to draw three to five middle and long branches and five to six leafy branches. The mean tree branches in the pods are short- and medium-cut, and in the strong cultivars (such as the big purple, etc.), only 1–2 medium and long branches and 3–4 leaf twigs are generally smoked. As a result, the short and medium cuts help to increase the growth potential and promote full flower buds and increase yield. (3) Short cuts. That is, cut 1/2--3/4 of the branches. Prosperous stems and extensions for short and heavy cuts can reduce total tree growth. The branches on the back of the backbone are heavy and short. In the second year, the new shoots are treated according to strong and weak, and straight oblique, and the resulting shoots can be cultivated. (4) Extremely short cuts. More than 3/4 of the shoots are cut, leaving only 4 - 5 shoots. In preparation for the removal of dense branches or replanting of multiple branches, extremely heavy and short cuts can be used. For the branches to be removed, the axillary buds at the base should be left short and heavy, and the results should be removed after bare baldness. The output of that year has also played a role in enhancing tree vigor. Extremely short cuts on the overhanging trees can result in a bouquet-like result. 2, throw away. That is, one-year branches do not cut. The growth is strong. After the branches are erected, the branches and branches increase, the photosynthetic area increases, and the amount of growth increases, which is not conducive to the balance of tree vigor and disturbs the tree shape. After the golden branches of the growing trend were dumped, the growth volume was small and the number of short fruit branches increased. The growth slowed down and earlier results were achieved. 3. Thinning. That is cut off branches from the base. It is mainly used to remove excessive auxiliary branches, leggy branches, weak branches, diseased branches and so on. Sparsely reduces the number of branches and causes wounds. It has a certain degree of weakening and alleviating effects on the growth of the whole tree. The larger the number of branches to be removed, the greater the amount, and the more obvious is the weakening and relaxing effect on the tree vigor. From a local point of view, the thinning still has the effect of inhibiting the growth of the upper part of the wound, that is, weakening the growth of the upper branch of the wound and promoting the growth of the lower branch of the wound. 4, shrinking shear. That is, a portion of the perennial branches are cut. Shrinking and shearing can rejuvenate growth, prompting the germination of latent buds and the formation of flower buds. It is mainly applied to the rejuvenation of the resulting branch and the rejuvenation of the backbone. 5, topping. That is, before the lignification of the shoot, a part of the tip was cut off. The purpose of saplings is to expand the crown, increase branching, and cultivate the branches. It can be used when the new shoots grow 30--40cm long. If you want to cultivate the result, you can pick up the heart twice in succession. 6, pull the sticks. It is a method of manually opening the angle of branches. It can weaken the apical dominance, ease the growth potential, increase the germination rate, increase the number of short branches, promote flowering, and improve early results. It can also improve the permeability condition of internal hemorrhoids, prevent the baldness of the internal hemorrhoids and the relocation of the resulting site, and increase the effective result sites. Improve production and quality. 7, carved buds and coated branches treasure. Above the shoots, a knife is cut transversely to the xylem. During the sapling reshaping, budding on the missing branches, or smearing twigs, can trigger new branches and expand the canopy. For the result tree, budding at the base of 1--2 year old shoots, or applying budding shoots on new buds, can sprout different types of fruiting branches and developmental branches and cultivate fruiting branches. 8, twist tip. The semi-woody new twists will sag. Twig shoots, growth tends to ease, accumulated more nutrients, is conducive to flower bud differentiation. The tip of the twister should be carried out from late May to early June, distorting the upright branches, competing branches and temporary branches on the back. The degree of distortion should be in the xylem, phloem and some cracks, but do not break. Pruning should pay attention to the following aspects: 1. The method of pruning should be determined according to the characteristics of the variety, tree age, tree vigor, planting density, cultivation method, and cultivation level. In addition, attention should be paid to the post-trimming reaction and problems should be adjusted in time. 2, when the thinning can not be too much, non-evacuation can not be, but also should be carried out gradually in years, to grasp the right amount of time and prevent oversight. When sparsely branching, the wound should be smooth and leave no branches, and the side of the wound should be inclined or downward, and the wound should be cut off after applying the wound protection agent. 3, the tip of the tip should be in the semi-lignified place of the new shoot. In addition, the twist tip applies hand operation and cannot be replaced with pliers or the like. 4, some varieties such as chicken heart, short purple, etc., picking the heart will reduce the number of development branches and growth, and even the formation of small old trees, should pay special attention.
