Preventive fumigation with fumigator can last for 5 days? Fumigating once every 7 days, and each fumigation (referring to the working time of the fumigator, the same below) is 1~ 1.5 hours. As a therapeutic fumigation, it can be fumigated twice every 3-5 days, each time for 2-3 hours; When the condition is serious, fumigate for 2~3 hours every day; When the condition is serious, the fumigation time can be extended to 8 hours a day, and the continuous fumigation can not exceed 3 days, and then it can be restored to 2-3 hours. At the same time, according to the different conditions of plant growth, disease-prone state, temperature and humidity, natural conditions and so on. Management should be strengthened, fumigation time should be controlled reasonably, and fungicides should be used together to achieve ideal control effect. Fumigation usually starts at night 18:00~20:00. After fumigation, keep the greenhouse sealed for more than 5 hours, and then ventilate to maintain the effectiveness of sterilization.
Installation: according to the effective radius of the fumigator, hang the fumigator evenly on the greenhouse or above the crops in the greenhouse with hanging wires or iron wires. For plastic film greenhouses and greenhouses, the distance between the fumigator and the plastic film at the top of the greenhouse should not be less than 1 ~ 1.5m to avoid damaging the plastic film. If the installation space is limited, in order to prevent the damage of sulfur gas to the greenhouse film, an umbrella-shaped waste film can be set above the fume extractor 1m to protect the greenhouse film (as shown in Figure 2), or the sulfur fume extractor and the protective cover can be directly integrated (as shown in Figure 3). For solar greenhouses, the fume extractor should be hung in the center of the greenhouse span direction or at the position of the back wall. The effective area of each fumigator should be controlled at 60~ 100 square meter. The wires and control switches shall be installed at a place 1.8m above the ground to avoid touching the operators. Wires should be routed along the greenhouse skeleton or column as far as possible, and switches should be installed on the column or back wall of the greenhouse operation corridor. The switch should be waterproof, moisture-proof, leak-proof and overload-proof; Steel wire should avoid foreskin shedding and steel wire exposure. Once the circuit and equipment are installed, they shall not be disassembled and moved at will.
Loading: take the medicine bowl out of the sulfur fumigator, remove the residue in the bowl and wipe the inner and outer surfaces of the dishes. Then, put the sulfur powder (or cake) into the bowl, and be careful not to fill it too full (not more than 2/3 of the bowl) to avoid boiling and overflowing. Generally speaking, the amount of sulfur powder added with fumigant is 30~40 grams each time.
Bowling: After cleaning the surface of the fumigator heater and the bottom of the medicine bowl, put the medicine bowl on the surface of the fumigator heater to ensure that they are in close contact and conduct heat.
Power on: Turn on the power supply, the fumigator will start to work, and cut off the power supply after the work is finished.
Function of fumigator 1 Improve human microcirculation;
During fumigation, due to the increase of external temperature, human capillaries expand and blood circulation accelerates, which can better promote the metabolism of newborn dust and the regeneration ability of tissues. Heat can dredge microcirculation, dredge meridians, let drugs directly reach the focus, regulate the intracellular environment, reconcile qi and blood, improve body function and enhance immunity.
Second, drug penetration:
When using the sitting fumigator, if it is combined with traditional Chinese medicine, it can penetrate into the skin in the form of ions after high temperature fumigation, which can achieve the purpose of eliminating toxins in the body and treating diseases. Especially for puerperal and postpartum patients, it is better to use traditional Chinese medicine fumigation physiotherapy to regulate maternal microcirculation and eliminate dampness and toxins in the body.
Third, the prevention and control function:
