Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to an intelligent controlled flame field management machine. Background Art

[0002] Soil-borne diseases are a type of extremely harmful plant disease that often causes large-scale plant death. There are many types of pathogens that cause soil-borne diseases, including fungi, bacteria, nematodes, viruses, etc., among which fungi are the main ones. How to disinfect the soil and overcome the obstacles of continuous cropping is a global problem that needs to be solved urgently. At present, the main preventive measures include agronomic measures, chemical methods, physical methods, biotechnology and integrated prevention and control. Physical methods usually use medium and high temperatures to kill pathogens, mainly steam disinfection, flame disinfection, electric disinfection, microwave disinfection and other methods. Flame disinfection uses the high temperature of flame to cause irreversible denaturation of proteins in organisms, thereby achieving the purpose of killing cells and organisms. Killing grass seeds can fundamentally reduce weed damage, killing insect eggs and pathogens can reduce pests and diseases, thereby reducing the use of pesticides and avoiding pesticide residues on crops. Killing grass can increase soil fertility to reduce the use of chemical fertilizers, which is suitable for application in ecological organic agriculture.
