2. Shoe type: The domestic version of the shoe is wide, and the foreign version will be much narrower;

3. Appearance: Due to the wide and narrow reasons, the ingredients of the foreign version are prone to form a trapezoidal structure of the upper narrow and width, and the domestic version may become a state where the upper and lower end tends to be flat.

4, sole material: For example, the outsole of most Vito 1 uses XDR's wear -resistant rubber outsole.The foreign version is a clear crystal transparent outsole.

In general, the core difference between the domestic and foreign version of the shoes is that the shoe is shoe, and the wide tadpole is indeed more in line with the design of Asian feet.However, Kuan Kuan brings a certain risk of rollover to some sneakers, which is indeed a little advantage in foreign version.Most domestic versions are trying to take care of the actual combat of the field.If your feet are narrow and feel that most of the front palms of the sneakers bought in the counter are empty, you can consider buying the same foreign version of the same sneakers.If you want to get the better performance of the same sneakers and put aside the sneakers with obvious design defects, the foreign version may not necessarily have a higher performance advantage than the domestic version.If you pay attention to durability, the domestic version of the shoe outsole is relatively durable.

1. Which of the Shading effect of aluminum foil Shading net and black net is better

1. Material comparison

Aluminum foil Shading net is a Shading material composed of multi -layer fiber mesh, aluminum foil, and PE anti -ultraviolet material. It has excellent ultraviolet -resistant, shielding, heat insulation and other properties, and has strong durability and compressive resistance.The black net is a Shading material made of HDPE material, which has the advantages of sunscreen, shielding, breathable, etc. Its advantage is that the price is cheaper and has good light transmission performance.

2. Comparison of Shading effect

The aluminum foil Shading net has a good Shading effect. Its special structure allows it to reflect the sunlight of the sun, reduce the direct radiation of the Solar, maintain temperature and increase water evaporation, thereby improving plant yield and growth quality.The anti -ultraviolet effect of this material is also excellent, which can effectively avoid the damage caused by ultraviolet rays to plants.The black net's Shading effect is slightly inferior to the aluminum foil Shading net, but for some occasions that need light transmission, the black net is a more suitable choice than the aluminum foil Shading net.

3. Select suggestions

When choosing a Shading material, we must first consider the application scenario. If the material is required to have anti -ultraviolet rays and Shading effects, it is recommended to choose an aluminum foil Shading net; if the material is better, you can choose the black net.In addition, the price of aluminum foil Shading net is relatively high. If the requirements are not high and the price is low, you can choose the black net, but you should pay attention to the quality of the material to avoid waste from buying inferior materials.

In summary, the aluminum foil Shading nets and black nets have their own advantages and disadvantages, and appropriate materials need to be selected according to actual needs.When purchasing, you should try to choose materials with quality and guarantee. Do not choose inferior products for cheap or other reasons, causing unnecessary economic losses.

2. How to distinguish the quality of the shade net

1. Material

The high -quality Shading net uses new polyethylene as the raw material, adding imported ultraviolet absorbers, antioxidants and good female mother production.

The inferior Shading net is made of recycling materials (old materials, flower materials) and inferior colors, and the ultraviolet absorbers and antioxidants are not added.

2. Appearance

The high -quality Shading mesh surface is flat, Smooth, shiny, uniform and clear with latitude and weft. In the sun, the color is black and black, the color is small, and the silk has no overlap.

The inferior Shading mesh surface is uneven, no gloss, no light, uneven latitude and weft, with gray black in the sun, large color difference, the silk mesh contains impurities, and the silk mesh overlap.

3, feel

High -quality Shading net feels soft, not rough, not stiff, and elastic.

The inferior Shading net has a rough feel, a bit stabbing, feels thick, and non -elastic.

4. Smell

The high -quality Shading net has no odor, and some are just a faint plastic scorching flavor.

The inferior Shading net is unpleasant, pungent, and plastic scorched flavor.

5. Quality

High -quality Shading nets have a Square gram of heavy gram, and the width and length are accurate. There are no holes in the mesh surface, no filament, strong single silk elasticity, and strong tensile ability.

The Square gram of the inferior Shading net is not standard, the width length is inaccurate, the mesh is hole, the silk is severe, and the single silk has no elasticity and no tensile force.

6. Life life

High -quality Shading nets have been used for more than 3 years under natural climatic conditions (excluding membrane, sulfur corrosion and polymeter areas).

The inferior Shading net is less than 1 year under natural climate conditions.

7. Economy

The high -quality Shading net is generally calculated according to the Square number, and the surface price is high.However, due to the light weight of the mesh, the actual length is accurate, the area is large, and the service life is long. It is much more affordable to calculate according to the service life of peace.

The inferior Shading net is generally calculated according to weight, and the surface price is low.However, due to the weight of the webbage, the actual length is insufficient, the use area is small, the service life is short, the labor cost is high, the cost of the shed is high, and it is not affordable.

There are three main types of plastic lenses, namely resin lenses, PC lenses, and acrylic lenses.

5. Resin material Sunglasses lens

Friends who often wear glasses must have heard of resin lenses, but what are the resin lenses?Resin (CR-39) is actually a chemical substance of the phenolic structure.

At this time, it was necessary to fertilize it at this time, and the frequency was about twice a month. nitrogen fertilizer and phosphorus and Potassium fertilizer could be used.At the end of June, alum Fertilizer can be poured once a week to reduce the pH value of the soil.

4, temperature

Huang Yilan is not resistant to cold. In winter, keep warm for the plant and keep the ambient temperature above 5 degrees. Otherwise, the plants will cause frost damage, causing plant death.

5. Watering

The principle of seeing dry and wetness should be followed during watering, and water does not need to be watered when the soil is not dry.Watering twice a day in summer, watering and watering every two days in spring and autumn, and watering once a month in winter.When the air humidity is too low, spray water for the leaves.

Third, how to trim Huang Yilan

1. Sparse branches

Sometimes the president of Huang Yanlan we breeding is particularly dense and intricate, so at this time we must cut off its too dense and overlapping branches. This can not only make the buds distributed balancedLight is conducive to growth.And you can find out the disease branch to avoid infection in time.2. Short interceptionGenerally speaking, as a bonsai plant in our family, the crown is more beautiful than the larger.So we trim in a short way to increase its crown.The short -cutting is generally cut off the newly grown branches buds 20 %, which can effectively suppress its growth, and at the same time stimulate the growth of the new branch buds, so that each part of the Huangyanlan grows evenly.
