Other claims from this paper (9)
- Intervention effect Soybean net photosynthetic rate, transpiration rate and yield increased at first and then decreased as irrigation and fertilizer levels rose.
- Intervention effect Partial factor productivity decreased as fertilization increased.
- Intervention effect Soil available nitrogen content showed the opposite trend to partial factor productivity as fertilization increased, that is it increased.
- Observation Interspecific competition intensity for light and soil water decreased from 2018 to 2019.
- Observation Root and soil nitrate nitrogen increased while interspecific competition intensity decreased from 2018 to 2019.
- Association The correlation of interspecific competition between aboveground and belowground parts was weak and varied between the two intercropping years.
- Intervention effect Treatment W3F2 had the highest comprehensive score in the principal component analysis.
- Recommendation Irrigation at 80% Fc combined with 92 kg ha-1 nitrogen fertilizer is the optimal combination for the apple–soybean system.
- Recommendation A water input of 4624.49–4795.75 m3 ha-1 a-1 combined with 84.10–107.27 kg ha-1 a-1 fertilizer is suitable for optimal irrigation and fertilization management of the intercropping system.
