- Intervention effect In 2021, foxtail millet biomass under PFE was 21.9% higher than under NP.
- Intervention effect In 2021, foxtail millet biomass under PFE was 3.2% higher than under MP.
- Intervention effect In 2022, foxtail millet biomass under PFE was 52.5% higher than under NP.
- Intervention effect In 2022, foxtail millet biomass under PFE was 17.7% higher than under MP.
- Intervention effect In 2021, the highest foxtail millet grain yield was under PFE, at 2480 kg/hm2.
- Intervention effect In 2021, foxtail millet grain yield under MP (2470 kg/hm2) was higher than under NP.
- Intervention effect In 2021, foxtail millet grain yield under NP (2343 kg/hm2) was lower than under MP.
- Intervention effect In 2022, foxtail millet grain yield was significantly higher under PFE than under MP and NP.
- Intervention effect Under PFE, soil temperature rose but stayed below that under MP.
- Mechanism The higher soil temperature under PFE increased the root growth process of foxtail millet.
- Mechanism The higher soil temperature under PFE increased soil enzyme (sucrase and urease) activity.
- Mechanism Increases in organic acids and soil enzymes assisted decomposition of soil organic matter.
- Mechanism Increases in organic acids and soil enzymes induced higher levels of available nitrogen and phosphorus.
- Mechanism Higher root reuse rates contributed to higher foxtail millet grain yields.
- Association Fewer holes in the PFE film improved film recovery.
- Intervention effect The film recovery rate under PFE was higher than under MP.
- Recommendation The unperforated film-covered planting pattern is suitable for millet production in sandy soil.
- Observation Foxtail millet biomass ranged from 27.69 g to 33.76 g per plant in 2021.
