- Intervention effect T2 increased available soil moisture by 19.3% versus CK.
- Intervention effect T3 increased available soil moisture by 28.4% versus CK.

- Observation Yield difference became significant across the stated drought range.
- Observation T1 gave maximum yield at drought occurrence of 18.2% to 36.4% per ten days.
- Observation T3 gave maximum yield at 54.5% drought occurrence per ten days.
- Recommendation Mulching was unsuitable for drought resistance above 63.6% drought occurrence per ten days.
- Recommendation The authors recommended 5 000 kg·hm-2 straw mulch in southern hilly red soils.
