Spring is the beginning of the new year and at the same time it is a critical moment for the prevention of pests and diseases in apple trees. In order to prevent and treat the infestation of apple trees in the later period, and also to prevent the occurrence of stem diseases such as ringworm disease, dry rot, and rot disease, the primary task at present is to do a good job of "spring spray."
The so-called "spring spray" refers to the spray before germination (dry shoots). Spring is the peak period of rot disease in the whole year, so the medicine for preventing rot disease in the bud must be hit. In addition, there are lurking lines, anthrax, and other pathogens, as well as maggots and scale insects such as red spiders, and their eggs. At this time, we must also use drugs to kill all germs and eggs. Off.
Therefore, dry sticks must not only be beaten, but also must be well hit, must hit the "wet, thorough, flow" standard, an acre of 400 pounds of syrup. This time medicine is being used, it is equivalent to killing pests and diseases in the cradle. At least it can help you to destroy about 70% of your survival. This greatly reduces the pressure of pest control throughout the year. In the prevention and control of pests and diseases, we advocated "treating early, treating less, and treating the disease."
Dry branching period is the season of exchange, it is easy to appear late spring, especially in the cherry during this period is very easy to cause freezing damage, so must be combined with drying branches medicine, which added 500 times "European" +500 times "flower face Kang †Enhance tree immunity and frost resistance. At the same time, 200 times more “oligosaccharide zinc†can be added to solve the lobular disease for the lobular disease.

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.
