In the first year, after the new planting of fruit trees, they should be dried and dried at a height of about 0.8 meters. When the new shoots grow to about 20 centimeters, the sprouts grown on the main trunk are cut off. When cutting, the cutting level should be emphasized. Every three buds are carved. The buds promoted sprouting and the main branch was pulled into an 80-degree angle in the autumn.
In the second year, the middle stem and the main branch were cut short and middling, and their buds were engraved. The branches on the head were cut short and heavy, the tree was controlled to prosper, and the branches were pulled in the fall.
In the third year, referring to the above-mentioned practices, except that the new ones with long branches and long growth are sparsely removed from the base, the remaining branches are all thrown away. The ring engraving is carried out in mid-June and the branches are also pulled in autumn. Afterwards, the annual practice is roughly the same as the third year. After several years of continuous pruning, the spindle-shaped structure can be achieved.
There are several outstanding problems in the trimming of apple saplings: 1. Do not pay attention to plastic surgery, using extensive trimming and extreme light shearing can easily cause the main, lateral branches and rearing branches to be separated. 2. Strengthen the tree shape, change the big tree. 3. Short cuts are excessively heavy, and the stocking and handling of the sticks are too quick. When the cutting of the stem branches is performed, the extension of the main lateral branch is too short, resulting in a small angle of the branches and a vigorous growth. 4. The strength of the tree is uneven, some of the main branches of the base are too strong, resulting in weaker and weaker; or the upper branches are excessively prosperous, and the upper and lower branches are weak and the trees are not balanced.
In short, the pruning of apple trees is not immutable. Different effective pruning methods should be adopted because of the different growth and density of the trees, ultimately allowing the orchard to be airy and transparent, cultivating high light efficiency trees, and planting high-quality apples.
Cosmetic ingredients are too broad a range. Our industry is usually divided into: 1. Basic ingredients, water or oil The main basic ingredients of general skin care products are distilled water or purified water, oil is vegetable oil or animal oil or mineral oil, according to the form of oil: liquid oil, semi-solid fat, solid wax. 2. Added ingredients, functional ingredients or control and adjustment ingredients Functional ingredients are mainly moisturizing, whitening, anti-aging, acne and other effective ingredients, according to different processes, plants as extracts, other organisms as extracts. Control components are preservatives, antibacterial agents, thickeners, emulsifiers, flavors, pigments and so on. Preservatives ensure that the product will not rot and deteriorate, antibacterial agents ensure that the product will not be infected by fungi, thickener to adjust the viscosity and flow variation, emulsifier to determine the product evenly dispersed into another substance, essence and pigment to ensure the stability of product smell and color. So, I don't know if that's what you want to know? Or do you want to know the names, the structures, the properties of the various monomer components, and if you want to know about that you can go to the INCI directory and Cos Dna for details
