Other claims from this paper (12)
- Intervention effect Straw returning and fertilization significantly increased soil organic matter.
- Intervention effect Straw returning and fertilization increased soil catalase, alkaline phosphorylase and urease activities.
- Intervention effect Straw returning and fertilization increased soil invertase activity.
- Intervention effect Storage root yield, single root fresh weight and commodity potato rate were significantly increased under straw returning and fertilization.
- Intervention effect The storage root yield was the lowest under the 50%S treatment.
- Intervention effect After two years of straw returning, storage root yield and commodity potato rate were highest under 100%S.
- Intervention effect After two years of straw returning and fertilization, sweetpotato starch and protein contents increased.
- Intervention effect Reducing sugar and soluble sugar contents decreased under 100%S and 100%S+N treatments.
- Recommendation The authors suggest that straw returning in full quantity is better than straw returning in half quantity.
- Intervention effect Storage root yield and commodity potato rate were highest under full quantity straw returning combined with conventional fertilization.
- Observation The taste of sweetpotato was changed by the treatment combining full quantity straw returning and conventional fertilization.
- Recommendation The amount of nitrogen fertilizer should be appropriately reduced in actual practice.
