An epidemic made us understand: there is no cure for viral infections, prevention first!
The hot search word for the Spring Festival in 2020 is the new coronavirus pneumonia. With boundless unknowns and panic, the Chinese are suffering in a long holiday like never before. The desire for work has never been so warm!
The virus, which is about 1,000 times smaller than bacteria, requires about 50,000 neatly arranged small life to fill a needle tip. It will quietly go up to nine days a week on a weekday, and go down to five oceans to catch it. The Chinese are obediently banned. Where is it sacred?
As this is probably the oldest and smallest living body on earth, the virus has wrapped us rigorously in all directions from sea, land and air. Viruses are non-existent living organisms. They must exist through the continuous self-replication of various animal and plant cells (hosts), including the human body. Fortunately, what is really worrying is only a small part of the virus family. And whether it is the human body or the plant, nature has designed a very sophisticated defense system for us, such as the human skin or the phloem of the plant, which is the first natural barrier that the virus cannot surpass. Therefore, the invasion of ordinary viruses is by no means easy.
Unfortunately, in the face of a handful of small and cunning viruses, people have not been able to find broad-spectrum special effects such as antibiotics. So far, the only virus that humans have eliminated is smallpox! !! !! In response to the flu that has been raging in North America for many years, scientists have spent huge sums of money to develop flu vaccines that are still only 60% effective. From the end of September 2019 to the end of January 2020, 19 million people were infected with the flu in the United States alone, and at least 10,000 people died. The reason is that the mutation of the virus is too random, and the speed at which scientists develop vaccines cannot keep up!
There is no cure for human virus infections, not to mention crop viruses with much less attention and research funding. How to do?
In the face of the fierce attack of new crown pneumonia, the daily homework we learn is to wash hands frequently, wear a face mask, disinfect households regularly, and keep the distance between people. The government has painstakingly taught us repeatedly that there is only one purpose: we cannot afford the virus, we must try to hide! How can crops prevent virus attacks?
Create a large environment of low-density viruses: crops are rooted in the soil and cannot move, so creating healthy water, soil, and atmospheric environments for them is a priority for growers. The atmospheric environment and irrigation water cannot be changed by most ordinary people, just like we cannot escape the torrent of new coronary pneumonia. Therefore, healthy soil is a daily homework that growers can do and must practice. How to simply and effectively create a healthy soil environment, and listen to the decomposition next time.
Reasonable dense planting: Does the endless Spring Festival holiday make you feel intimate and intimate is very pleasant (zhi4) fast (xi1)? Isn't a distance of more than one meter far enough? The same is true for crops. Maintaining a scientific planting density can not only maintain good ventilation and ventilation, but also reduce various mechanical frictions and effectively reduce the risk of infection.
Reduce the infection of foreign viruses: Don't come, Wudi, is our common greeting for the Spring Festival, the purpose is to reduce the risk of infection with foreign viruses. Detoxifying seeds and disinfecting themselves and tools before agricultural operations are also important daily operations for the purpose of reducing virus infection.
The last point is also the most important point. Whether it is humans or crops, iron must be hardened, and improving immunity is the key! From skin to body, including neutrophils, T cells, B cells, macrophages, and many other cells, those with high immunity naturally have an elite army with excellent weapons. The same is true of plants. A robust plant itself has a complete immune system to resist foreign invasion. Therefore, the selection of crops with antiviral varieties, balanced nutrition, and improved crop immunity are also very important in planting.
