The application of soilless culture techniques for Dendrobium candidum has become more and more widely used by users in dozens of provinces and cities in Beijing, Shanghai, Jilin, Zhejiang, Jiangxi, Hebei, Shanxi, and Shandong, etc. Fermenting all kinds of bark, straw and leaves is the most convenient, economical and effective method. The nutritious soil produced is a very ideal material for the cultivation of Dendrobium candidum. It has very good economic and ecological benefits and is well received by users. welcome. Then, what are the conditions for the application of fermentation substrate nutrition soil in Dendrobium candidum?
1, the matrix ecological environment. Soilless cultivation requires that the seedling substrate is essentially free of live pathogens, eggs, and contains no or minimal amounts of harmful substances to prevent it from contaminating the environment and the food chain as the Dendrobium candidum enters the growth phase. The nursery substrate should be fermented by the golden treasure fermentation agent under the conditions of rapid high-temperature fermentation, to achieve the purpose of anti-virus disinfection, removal of eggs, can guarantee the ecological conditions of Dendrobium candidum, to provide a more valuable ecological precious herbs.
2, the physical and chemical characteristics of the substrate. The matrix is ​​more conducive to plant growth than the soil in terms of nutritional conditions and growth environment. However, it still needs to have other functions of the soil, such as facilitating the winding of the root (in order to facilitate) and better water retention. The substrate fermented by the goldfish starter can be freely formulated according to the nutritional requirements of Dendrobium candidum.
3, the matrix deployment is reasonable. When formulating the nursery substrate, care should be taken to scientifically and logically combine the organic matrix and the inorganic matrix to better regulate the aeration, moisture, and nutritional status of the nursery substrate. The matrix is ​​required to have a strong chemical stability, the matrix does not contain toxic substances, the chemical balance of the matrix is ​​maintained, and it is easy to manage and ensure the normal growth of the crop.
4, stable matrix performance. The matrix composed of plant residues, such as peat, sawdust, rice hulls, bagasse, etc., has a relatively complex chemical composition and has a great influence on the matrix. Fresh straw, peat, and incompletely bark, bagasse, etc., contain substances and toxic substances that are easily decomposed by microorganisms. They may cause strong biochemical changes due to microbial activity at the initial stage of use, seriously affecting the balance of the matrix and poisoning. Root system. These organic materials need to be fermented with the groovy matrix starter, and the organic components are decomposed into stable substances such as lignin and humus so that the stability of the soilless culture substrate can be maintained.

COVID-19 Non-contact Thermometer
The Thermometer that Sanan Technology mainly runs is the Infared Thermometer for Humans/ COVID-19 Non-contact Thermometer.
The classifications of the Infared Thermometer
The Infrared Thermometer are mainly divided into the Contact Infrared Thermometer and the Non-contact Infrared Thermometer(Thermometer Non Contact).
As for the Contact Infrared Thermometer, the Ear Thermometer is commonly used.
The using way of the Ear Thermometer:
1. Gently straighten the ear canal;
2. Insert the temperature measuring head into the ear canal;
3. Press the upper end of the temperature measurement for one second;
4. The Accurate body temperature can be read from the LCD screen;
Safe and secure. And it is safe even if the whole family shares if only we replace the protective rubber cover when using it(to avoid bacterial infection).
While, as for the Non-contact Infrared Thermometer(Thermometer for Fever), the most common type is the Forehead Thermometer.
The using way of the Forehead Thermometer:
1. Point the probe at the forehead;
2. Press the measuring button
3. The measurement data can be obtained in just a few seconds
Very suitable for the patients with acute and serious illness, the elderly, infants and children. However, in the early stage of use, users may get several different measurement data because they are not familiar with this operation method. Generally speaking, the measured maximum value is the desired data. And the users will be more satisfied with this kind of thermometer as they get familiar with it.
All in all, the advantages of infrared thermometers(Thermometer Body Temperature) are convenient, simple, fast, and quite accurate to collect body temperature, and its disadvantage is that it can be easily affected by the the ambient temperature, and in this case the error will be large. Here are some tips about the thermometers as follows, hope it helps when you choose and use a thermometer.
Tips:
1. People with ear diseases such as the external otitis and otitis media should not use the ear thermometer.
2. Do not use the ear thermometer when the ear holes are wet after swimming or bathing.
3. When the person under test comes from a place where the temperature is very different from the temperature of the environment, he/she should stay in the measurement environment for at least 5 minutes to make the 2 temperature data becomes similar and then measure the body temperature.
5. Using the cold compresses and other cooling measures on a fever patient will make the measurement result lower. Please avoid the temperature measurement in this case.
6. Please don't measure the body temperature in the places with large air currents such as the fans and air conditioners.
7. Please don't measure the body temperature in direct sunlight.
8. We advice to measure about 3 times during the measurement with the interval between each measurement 3-5 seconds, and select the most displayed set of data.
