The main purpose of pruning grapes in winter is to ensure a certain amount of buds, regulate growth and results, so as to ensure that good fresh buds are issued every year, in order to achieve the goal of increasing yield and yield in successive years. First, early pruning of grape leaves should be trimmed as soon as possible in order to facilitate soil buried in cold, must not wait until the spring pruning before sprouting, to prevent the outflow of nutrient solution, resulting in debilitating tree vigor. Second, the pruning method 1. Sparse cut: In order to ensure that each main vine can be equipped with a result of a certain distance of the mother branch group, to be unnecessary or can not use the branches completely cut off from the base. 2. Short cuts: When pruning in winter, it is customary to cut the mature one-year branches to the required length. General short shoots stay 1 to 2 knots; tips stay 5 to 7 knots; long tips stay 8 to 12 knots. Mature, strong growth of the new shoots can be properly long cut; growth is weak, poor maturity, fine can be short to stay; branches of vines with low strength of the species, should adopt the middle, long tip pruning; vines sparse place for full The use of space can stay for a long time; for summer trimming can be shorter and shorter, and the new shoot for growth should stay for a long time. 3. Update Pruning: The dendrites that move up or forward too quickly in the result area are cut and replaced with mature shoots that occur at or near their base. Here is a brief introduction of the two-branch renewal method: a result branch usually consists of one mother and one parent, resulting in long mother leaves, long and medium tip pruning, and two or three buds from the following preparatory branches. Alternate. Using this method to cultivate new shoots is more reliable, and it is suitable for varieties with weak branching ability. Third, pay attention to grape vines loose tissue, pith large, moisture, nutrients is easy to lose, shoots should be trimmed on the shear buds 3 to 5 cm at the cut section or cut the upper end of the bud section cut. When pruning, cut dead branches, branches and branches, useless secondary branches and leggy branches. Long leg buds with small buds and eyelids tend to cause serious blinding. They should be removed or shortened, and new shoots that are fully mature and full of hypertrophy should be retained. When the branches are cut, the cuts should be controlled about 1 cm from the base. Do not cut them close to the base. After the stumps have dried up, cut them off from the base. For summer shoots or winter shoots with a thickness of 0.8 cm or more, mature shoots can be left in 2 to 3 knots, and weak growth should be cut off.
A mixture of Cosmetic Raw Materials, which is made up of various raw materials after reasonable dispensing. Cosmetics have various kinds of raw materials and different properties. According to the properties and uses of cosmetics, they can be broadly divided into two categories: matrix materials and auxiliary materials. The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetics formula and plays a major role in cosmetics. The latter plays a role in shaping, stabilizing or giving color, fragrance and other characteristics of cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are made from natural, synthetic or extracted substances with different functions as raw materials by heating, stirring and emulsifying processes.
The main raw materials of cosmetics are commonly used as matrix materials and natural Additives. The general base materials for cosmetics include: oily raw materials, which are the most widely used raw materials for cosmetics, play a protective, moisturizing and softening role in skin care products, play a stereotyping and aesthetic role in the use of products; surfactants, which can reduce the surface tension of water, with decontamination, wetting, dispersion, foaming, emulsification, thickening. Other functions, known as industrial monosodium glutamate, moisturizing agents and essential ingredients for cream cosmetics, are used to prevent dry and cracked paste and keep skin moisture. Adhesives are mainly used for hair gel, mousse and gelatin mask. Powder is mainly used for making powder products, and pigments and dyestuffs are mainly used for cosmetic modification. Products; preservatives, antioxidants, in the cosmetics shelf-life and consumer use in the process of inhibiting microbial growth; perfumes, increase cosmetic fragrance, improve product value; other raw materials, including UV absorbers, dye intermediates used for dyeing black hair, perm raw materials, antiperspirant, deodorant, anti-dry skin crack Raw materials, anti acne raw materials, etc. Common natural additives are hydrolyzed gelatin, hyaluronic acid, superoxide dismutase (SOD), Royal jelly, silk fibroin, mink oil, pearls, aloe vera, malt meal stone, organic germanium, pollen, alginic acid, seabuckthorn, Chinese herbal medicine and so on.
