No-pollution gas used as field pesticide and sterilizer and using method

Abstract

The present invention provides a new use of no-pollution gas, CO2, N2 and other no-pollution gases are used as field pesticide and sterilizer. After some area is sealed, the no-pollution gas is filled in to make no-oxygen environment killing pest, pathogenic bacteria, etc. After that, air is made to enter to restore the soil environment for plant to grow. The present invention makes it possible to produce green product, lower plant cost and increase plantation utility.
