With the improvement of agricultural production level, the advantages of seed germination technology are increasingly reflected, and the use of artificial climate box seed germination, can make the seedlings germinate timely and neat germination, in the increase seedling seed germination rate can also enhance the resistance of seedlings Sex, such as disease resistance, drought resistance, heat resistance and drought resistance, has increased the yield and quality of seedling production. Therefore, prior to sowing, seed germination using artificial climate boxes has become an important part of modern seedling raising and afforestation.
However, in the process of using artificial climate box seed germination, some places need special attention, the first point is to pay attention to the humidity in the artificial climate box, and secondly, to strive for uniform temperature and moderate light. However, the artificial climate box is a special device capable of computerized control of temperature, humidity, light and other conditions, and has obvious advantages in controlling the environment.
The reason why the humidity of the artificial climate box is strictly required is mainly because the low humidity seed is not easy to germinate and the humidity is high and it is easy to rot. Therefore, in the process of using artificial climate box seeds to germinate, it is necessary to utilize the regulation function of the equipment, The relative humidity in the box is maintained under suitable conditions to meet the germination requirements of the seeds. In addition, temperature and light are necessary conditions for seed germination, and the temperature is uniform, the seed germination will be neat, so the temperature in the artificial climate chamber is generally required to be uniform, and the light should be humidity, for example, the temperature uniformity of the artificial climate chamber is less than 1°C. .
Artificial climate chamber is the ideal equipment for seed germination and determination of seed germination rate. At present, with the development of technology and the further improvement of control technology, artificial climate chambers are highly precise in controlling the environment such as temperature, humidity, and illuminance. As long as they are adjusted and controlled according to the requirements of different seed germination, they can basically meet the requirements.
1.Welding materials
In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.
The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
Welding can be applied in different kinds of industries such as building and construction, oil and gas, marine, power generation, steel, mine tools, automobile, transportation and etc.
