Other claims from this paper (11)
- Observation Sixteen weed families and 31 weed species were identified in the tea plantations.
- Observation In April, dominant weeds grew slowly, had low biomass and were under 30 cm.
- Intervention effect In July, malignant weed abundance was 0.256 with straw mulch versus 0.788 under clean tillage.
- Intervention effect In September, malignant weed abundance was 0.420 with straw mulch versus 0.759 under clean tillage.
- Intervention effect White clover intercropping had lower malignant weed occurrence frequency.
- Intervention effect Straw mulch lowered the weed dominant concentration index relative to clean tillage across seasons.
- Intervention effect White clover intercropping lowered total weed number relative to clean tillage.
- Intervention effect White clover intercropping lowered weed biomass in spring, summer and autumn.
- Intervention effect White clover intercropping lowered mean weed height in summer and autumn.
- Recommendation The authors concluded that white clover intercropping is an effective ecological weed control measure.
- Recommendation The authors concluded that straw mulching is an effective ecological weed control measure.
