High flow oxygen therapy (HFNC) is a kind of oxygen therapy that directly transports a certain oxygen concentration of air oxygen mixed with high flow gas to patients through a soft nasal cannula. Also known as transnasal high flow oxygen therapy, high flow humidification oxygen therapy. HFNC has unique physiological effects: Constant oxygen concentration, Good effect of temperature and humidity, To flush the dead space of the nasopharynx, Give some positive airway pressure, Good comfort.

First, yellow board production and purchase
1. Hand-made: The board material is generally made of calcium plastic board, plywood, thin metal sheet, etc. of a certain thickness of waste cardboard, pesticides and other packing boxes. The insecticides and accessories used commercially available No. 10 engine oil, petrolatum, butter, honey, etc., No. 10 engine oil, butter, Vaseline, etc. were used as a stickworm alone, but also can be mixed with a certain amount of Vaseline or butter after the No. 10 motor oil. For insecticides.
Homemade method:
(1). On the front and back sides of a certain size of plate material, use a brush to evenly coat the previously prepared yellow paint. After the paint is dried, attach the yellow plate to a wooden stick of 1 to 2 meters or directly fix it in the field shed. On the shelf. After inserting into the field or fixing in the shed or shelf, evenly apply yellow insecticide on the front and back sides of the yellow plate, and then apply a small amount of honey to produce it. Replace it once every 10 to 15 days or remove the insect. Apply the insecticide once.
b. Sticky fly paper can also be used directly on the prepared yellow plate.
(2) Or use two pieces of yellow paper of the same size, with the yellow side facing out, stick the two papers firmly, and then cover it with a transparent film to prevent rain. The film wall is covered with the insecticide and then used.
2. Purchase: In recent years, China's armyworm board production technology has developed rapidly, such as Jiaduo, Jiahe and other new generation of yellow board products, with strong viscosity, good trapping, anti-aging, easy to use and so on.
Second, the application of yellow field technology Place a height of 15-20cm at the top of the crop, the board surface is appropriate to the thing, 20cm30cm specifications about 20 pieces, depending on the situation of the armyworm is regularly replaced.
Yellow trap production and application technology
With the requirements for the improvement of the quality and safety of agricultural products, yellow-board trapping technology is increasingly used in pollution-free and green agricultural production. The production and application technology of trapping yellow plates are now described as follows:
