Background

With the popularization of the control of the incineration of the crop straws and the protective farming technology in the countries in recent years, more and more crop straws adopt a treatment means of returning the whole amount of the straws to the field, namely, the straws are cut and then accumulated between seedling belts or buried in soil, thereby realizing the purposes of harmless treatment of the straws and soil improvement. However, after a large amount of straws are directly returned to the field, pests, ova and pathogenic bacteria in the straws are also buried in the soil and are propagated in the soil in a large amount, and if manual intervention treatment is not carried out, the growth of crops and the agricultural yield are influenced. For this reason, it is common to spray chemical pesticides into the soil to kill pathogenic bacteria, kill eggs, and repel pests, but long-term application of chemicals causes chemical pollution to the soil and surface water, and volatilization of part of the pesticides into the air further causes pollution to the atmospheric environment.
