**Organophosphorus Degradation Technology Plan (Autumn Cabbage, Spinach)**
The test crops selected for this study were autumn cabbage and spinach. Each crop had two experimental groups, with five plots per group. Each plot measured 33 m², resulting in a total of 90 m². The base fertilizer used was farmyard manure.
The experimental design included the following treatment groups:
- **Group 1**: Organic phosphorus
- **Group 2**: Seaweed extract + Atropine
- **Group 3**: Biopterin
- **Group 4**: Seaweed extract + Organic phosphorus
- **Group 5**: Seaweed extract + Biapozyme + Atropine
- **Group 6**: Base fertilizer only (control)
Each plot was covered with plastic sheeting during application to prevent cross-contamination between treatments. All treatments were applied strictly according to the manufacturer's instructions.
For Group 2, BiPAP was applied 2 hours after organic phosphorus application or 2 hours before harvesting. One tablet per area was used, with atropine applied one hour before harvest. The solution was fully dissolved and sprayed once, ensuring it was applied within one hour of preparation.
Organophosphorus residue testing was conducted by a qualified local inspection agency. Observations were recorded throughout the growing season at each key stage.
Seaweed extract was diluted 800–1000 times and sprayed every 7 days. This method helps improve plant disease resistance and promotes healthy growth. During spraying, iodophors are formed, which assist in degrading organophosphorus compounds by interacting with "iodine and phosphorus."
Organophosphate insecticides such as dichlorvos, 1605, 1259, etc., enter plants and bind to the phosphoryl group in cholinesterase, causing acetylcholine to accumulate. However, seaweed extract can help convert these into non-toxic substances. It shows better detoxification effects on 1605, 1059, Tepu, and ethionium, but is less effective or ineffective against dichlorvos, dimethoate, trichlorfon, malathion, diazinon, methamidophos, propylamine fluorophosphate, and octopamine.
Atropine is commonly available in pharmacies. It is used as an organophosphorus antidote, typically at a rate of 2 tablets per square meter (33 m²), crushed and dissolved in water, then mixed with seaweed extract and sprayed.
Biapozyme is used by rotating the bottle in the direction indicated on the packaging until the enzyme powder falls into the diluent. It should be shaken until fully dissolved and used at a ratio of 500 ml per bottle to 160 pounds of water, covering 1 mu of land. It is fully sprayed on leaves and foliage. It directly targets organophosphorus residues, degrades the phosphoenzyme chain, and breaks down toxic components into non-toxic, water-soluble molecules.
**Notes:**
1. Seaweed extract and atropine can be mixed.
2. Biapozyme must be used alone.
3. Multiple pesticide antidotes should be applied 2 hours before sunrise or after sunset for optimal results.
This plan ensures systematic monitoring and efficient degradation of organophosphorus residues while maintaining crop health and safety.
