Ten methods for cold-proof vegetables

1, nitrogen control method: appropriate reduction in the amount of nitrogen fertilizer at the seedling stage, must not be partial nitrogen fertilizer, so as to avoid the cold resistance of plants. Top dressing is early, in order to promote vegetable seedlings. Before the low temperature, you can't apply the available nitrogen fertilizer, and you should top-up a phosphorus and potassium fertilizer to enhance the cold resistance. 2, the application of organic fertilizer method: the use of pig cattle manure or soil fertilizer and other warm farm fertilizer, circle cultivation at the root of the root of the vegetable tree, can increase the root soil temperature 2-3 °C. Fertilization should be carried out on sunny days, 1,000-1500 kilograms per mu. 3. Casting manure: 400-500 kg of thin manure poured per acre before frost, so that the soil is not easy to freeze. 4, soil method: the combination of cultivators before freezing, with crushed soil to cultivate the roots of soil, can make the soil loose, increase soil temperature, but also directly protect the roots. However, the cultivating soil must be carried out before the soil is frozen. The depth should be 7-10 cm. 5. Coverage method: In the afternoon before the onset of frost, straw, rice straw, etc. are used to cover vegetables and vegetables, which can reduce wind and cold mechanical damage. Use 100 kg of straw per acre. Disperse it sparsely and cover all vegetables to prevent affecting photosynthesis. 6, ash method: First, in the cold before the onset of cryogenic damage on vegetables in a thin layer of husk ash or plant ash; the second is to spread grass ash between the rows. 7. Smoke-curing method: stacking piles with weeds, straw, litter, etc., or making frost-proof bullets with asphalt, ammonium nitrate, coal powder, sawdust, etc., and ignite and smoke at the corners of the top of the wind before the frost arrives. Smoke can dispel cold currents. 8, Wind Barrier Law: In the north side of the vegetable pot used as straw and other 1-1.5 meters high wind barriers, every 3-4 sets a wind barrier. 9. Winter irrigation method: The irrigation time before freezing should be reduced to the daily average temperature of 2-5°C. After freezing, the maximum temperature rises to 2-3°C after the cold water is poured, and the soil and vegetable trees are thawed. The winter irrigation should be poured with enough water to make it full of water. 10. Drainage method: Open "Three Ditches" to ensure the smoothness of the ditch so that the frozen water can be eliminated in time.

Air Purifier

Dynamic disinfection is a process of disinfection and cleaning of air and surfaces in indoor Spaces. A
new method of safe disinfection that does not cause harm or interference to people and the environment on
site.The charged particles and active oxygen components produced by the low-temperature plasma in the
equipment play a major role in the process of killing bacteria and viruses, and have the effect of
broad-spectrum sterilization. It can not only inactivate aerosol plankton in the air and bacteria
and viruses on the surface of object but also effectively decompose formaldehyde and volatile organic
compounds, degrade all kinds of bad smell and purify it Air environment.A small amount of high purity

zone.

Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to decoration pollution that can absorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc. , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.

There are many different technologies and media in air purifiers that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Carbon core filter technology, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time.
