Greenhouses are strictly sterilized before sowing, which can effectively reduce the occurrence of pests and diseases. There are three ways to disinfect:
High-temperature disinfection: During the high temperature period, the shed film is affixed, and the shed is sealed in all places, so that the temperature in the shed is raised to 40-50° C. or even higher. The pathogenic bacteria are killed by high temperature and the virus is inactivated. If you miss the high temperature period, you can also use the stove heating for high temperature disinfection.
Sprinkle pesticide: Normally 400 square meters of greenhouses are spread on the ground with 70% dikeson and 65% zeaxen, 1.2 kg each, and 40 kg of wet soil. Or combine the two pesticides into a 300 times liquid to sprinkle the soil surface. After deep-turning, there are sheds and floor tigers harm the shed room, can be used 90% trichlorfon 0.3 kg mixed bran 1 kg of wheat bran bait, sprinkled on the ground to seduce.
Lime milk brush white: made of high-quality quicklime made of milk, brushing the gables in the interior walls and back walls, can effectively kill the bacteria hidden in the wall.
Most products of Fluorine-Containing Benzaldehyde are a pale yellow liquid. They are playing an important role in fine chemical intermediates, is used as the main raw material for the synthesis of a variety of pesticides, pharmaceuticals, surfactants, polymer monomer mildew. As used in medicine synthesis antihypertensive drugs, antipyretic analgesic anti-inflammatory drugs, anti-cancer drugs, muscle relaxation drugs for synthesizing fluorine cypermethrin, fluorine chlorobenzene daisy cool in pesticides, fluoride and styrene, wherein the polymer of styrene monomer to fluorine can be widely used in the manufacture of the recording material, a thermoplastic resin coating, liquid crystal materials. Currently new miticide is effective pesticide products which is the main raw material of Fluorine-Containing Benzaldehyde.
