- (1)
- No-till technology is primarily used for wheat and maize, as it reduces soil disturbance, increases soil organic matter content, and enhances soil carbon sequestration capacity, thereby reducing carbon emissions [55].
- (2)
- Strip tillage technology is more commonly applied in maize production, as it helps retain soil moisture and reduces both wind and water erosion [56].
- (3)
- Minimum tillage technology is suitable for various crops, improving land-use efficiency while minimizing carbon emissions caused by mechanical plowing.
- (1)
- Agricultural control: disease-resistant variety selection and seed treatment for pest prevention.
- (2)
- Physical control: insect-proof net technology, pheromone traps, and insecticidal lamps.
- (3)
- Biological control: conservation and utilization of natural enemies, biological pesticide technology.
- (4)
- Chemical control: deep plowing and water irrigation for pest suppression.
