In recent years, Japanese researchers have developed a simple soil disinfection method that has a good disinfection effect and does not harm the environment. The majority of vegetable farmers may wish to try.

The specific operation procedure of this soil disinfection method is: spraying the soil with water with a concentration of about 2% of alcohol, and then covering it with a plastic film for 1 to 2 weeks. Researchers said that alcohol can reduce the amount of oxygen in the soil and thus have the effect of disinfestation.

According to reports, this new method can easily kill pests and pathogens in the soil. The disinfection effect is almost equivalent to methyl bromide, and the latter is gradually banned because it will destroy the ozone layer (China's total disablement period is 2015, Shandong Province is 2014, Hainan Province. The province has been banned since November 2010). After a few days, alcohol will decompose in the soil and will not affect the environment.

The researchers conducted experiments for about one week in the cucumber field. The experimental results showed that the roots of the cucumbers cultivated in the soil that had not been sprinkled with alcohol solution had parasites, while the cucumbers in the alcohol-treated soil grew normally and no parasites were found in the roots.
