In the case of poor climatic conditions, seeds sown in the natural environment tend to germinate more difficult, and it is more difficult to control the management of seedlings. Therefore, artificial climate chambers can be used at this time to artificially create a good environment to cultivate appropriate age. Strong seedlings, once the climatic conditions are suitable for replanting in Daejeon. Since artificial climate chambers can create ideal seed germination conditions according to artificial needs, artificial climate chamber seedlings have the following advantages: 1. Shorten the time of seed germination Seeds in the natural environment are more or less disturbed by the external environment, so that their germination potential cannot be fully stimulated. Therefore, the germination time is very uncontrollable, and the artificial climate chamber is used to create suitable seeds according to different seeds. The environment, temperature and humidity are uniform, so the seeds germinate quickly, homogeneous, uniform and strong, shortening the time of seed germination. 2. Improve seedling vigor and disease resistance The artificial climate chamber not only provides a comfortable climate for seed germination, but also provides a clean growth environment. Therefore, artificial climate chamber seedlings can improve seedling vigor and disease resistance, and achieve seedlings and seedlings. After the colonization of Daejeon, the seedlings have a higher survival rate and better quality. The artificial climate chamber has beautiful appearance, high temperature control and humidity control, and good stability. The application of the instrument not only provides convenience for seed companies and testing departments to carry out seed germination rate detection, but also provides technical support for planters, seed stores, etc., and is an important instrument for improving the quality of agricultural production. In the agricultural planting activities, this method is used to raise seedlings, solve the seed germination and seedling problems, meet the high quality requirements of modern agricultural production for seeds and seedlings, and lay an important significance for achieving intensive, industrialized and standardized production. An important foundation. At present, many enterprises and units have begun to purchase artificial climate boxes, and enhance their core competitiveness by strengthening seed testing and seedling management. Oxide powder for thermal spray refers to a type of powder material that is used in thermal spray processes. Thermal spray is a coating technique where a material in powder form is heated and propelled onto a substrate, forming a coating.

Oxide powders are commonly used in thermal spray applications due to their high melting points, excellent wear resistance, and thermal insulation properties. They can be used to create protective coatings on various surfaces, such as metals, ceramics, and plastics.
Some common types of oxide powders used in thermal spray include:
1. Aluminum oxide (Al2O3): This oxide powder is widely used for its high hardness, wear resistance, and thermal insulation properties. It is commonly used for coating applications in industries such as aerospace, automotive, and electronics.
2. Zirconium oxide (ZrO2): Zirconium oxide powder is known for its high melting point and excellent thermal barrier properties. It is often used in thermal spray coatings for gas turbine engine components, where thermal insulation is critical.
3. Chromium oxide (Cr2O3): Chromium oxide powder is used for its high hardness, corrosion resistance, and wear resistance. It is commonly used in applications where high temperature and abrasive wear resistance are required.
4. Titanium oxide (TiO2): Titanium oxide powder is known for its high refractive index and excellent UV resistance. It is often used in thermal spray coatings for optical and decorative applications.
These oxide powders can be applied using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel (HVOF) spraying. The choice of oxide powder and thermal spray technique depends on the specific application requirements and desired coating properties.
