1. Lightly based, simplified trimming; overall slow release, four seasons adjustment.
2. Due to the tree system, comprehensive regulation. Because winter pruning is a very technical and practical method of operation. However, we must truly grasp and use it freely: First, we must fully understand the pruning physiology of fruit trees, and correctly use the characteristics of apple branching and branch bud heterogeneity; then, combine the site conditions of different orchards, the varieties of gardens, Planting density, growth conditions, and cultivation management levels, etc., can be achieved by adopting flexible pruning methods to achieve correct pruning and reasonable adjustment.
3. Look for flower buds and finely trim. For the big year tree that has entered the early stage of the fruit, it is necessary to pruning the branches for years, which not only can increase the yield and promote the quality, but also can be adapted to the tree potential and the planned yield by controlling the flower bud retention. The effect is more obvious than thinning and thinning. In addition, because the reserve shoots are left behind, sufficient flower buds can be formed at the same time as the results, which plays an extremely important role in preventing and eliminating the "years and years" phenomenon.

Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
