Take the back branch, the fruit farmers in many places like to leave a short pile when they are stripping their backs. As a result, in the coming year, not many dry piles are formed, or a pile of slivers emerges. When the back side and the back branch are removed, the cuts are kept very close, causing a lot of prosperous branches on the back side of the cuts in the coming year, but they are unable to make branches under the back, which makes the back more prosperous and the strips keep moving. How to keep the cut? To achieve "sparse on the back, back side of the horse, back to stay buds." This means that when the branches are removed, the cuts should be flat and the piles should not be left; when the back branches are removed, the cuts should be downwards and outwards, as if they were horse ears. The advantage of this is that in the coming year, the branches will not be tied, and the branches under the cuts will not grow because they are close to the back. When you want to get rid of the lower branches, you need to leave a bud to encourage it to make new branches in the coming year. It is also to "promote and suppress" and prevent the back from being stripped (because there is an advantage on the back). In this way, the back, back and back are mutually restrained, and the growth of the whole branch will be in a state of balance and stability, which is beneficial to the good flowering and good fruit. Similarly, when you go to the big branch, you can also pay attention to it. You have to "saw the back of the tree, leave a centimeter, the slash should be flat, and the wound protection is good." When the saw is used, it should be sawed from top to bottom. The saw back should cover the tree body. The saw blade is slightly inclined outwards. The kerf is left in the shape of a horseshoe. The lower part of the slash is only 1 cm long from the trunk (so-called oblique sawing pile), saw The mouth must be flat. If it is very rough, use a knife to cut the side and finally apply a healing agent to protect the wound. This will not weaken the growth of the middle and the wounds, and the slash will not send too many branches in the coming year. This is because the scalloped flat oblique wound heals faster. If the kerf is attached to the tree body up and down, it will weaken the growth of the middle and is not conducive to the healing of the wound. If the shovel stays too long, it will be beneficial to the healing of the wound. However, in the coming year, many branches will be emitted from the upper and lower sides of the slash, which will waste nutrients. Food additives refer to chemical synthetic or natural substances added to food for the purpose of improving food quality, color, aroma and taste, as well as for the needs of anti-corrosion and processing technology. Generally, food additives may not be food and may not have nutritional value, but they must conform to the concept of the above definition, that is, do not affect the nutritional value of food, and have the function of preventing food spoilage, enhancing food sensory properties or improving food quality. buy food Additive ,wholesale food Additive,food Additive for sale,food additive benefits Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptide-nootropics.com
Generally speaking, food additives can be divided into natural and synthetic categories according to their source. Natural food additives refer to natural substances extracted from the metabolites of animals, plants or microorganisms as raw materials. Chemically synthesized food additives refer to substances obtained by chemical means through oxidation, reduction, condensation, polymerization, salt formation and other synthetic reactions of elements or compounds. Most of the chemicals used today are synthetic food additives.
According to the use, the classification of food additives in various countries is almost the same, the difference is mainly the difference in the classification of how much. The United States divides food additives into 16 categories, Japan into 30 categories, China's "Health Standards for the Use of Food Additives" divides them into 22 categories: Antioxidant preservatives (1) (2) (3) (4) bleach hair color agent (5) concreting citric acid (6) (7) loose agent (8) thickening agent defoaming agent (9) (10) sweetener (11) colorants emulsifier (12) (13) improver (14) anticaking agent (15) flavor enhancer (16) (17) of enzyme preparation was preparing foaming agent (18) (19) preservatives (20) spices (21) nutritional fortifier (22) other additives.
Fruit tree winter shears, how to leave the kerf?
The fruit tree is trimmed with a saw, the technique is really simple, the branchlets are made of scissors, and the thick branches are sawed. However, the same branch, let different people do it, but it will have a completely different effect, the problem lies in the difference between the cut and the saw.
