Other claims from this paper (12)
- Intervention effect Mixed-species planting significantly increased the tree growth index of Alnus formosana.
- Observation In mixed forests A. formosana had higher diameter at breast height, tree height and crown width than P. massoniana.
- Observation In mixed forests A. formosana had higher clear bole height and tree volume than P. massoniana.
- Observation A. formosana exerted stronger competitive effects on DBH and CW (slope 1.12 to 1.27) than P. massoniana (slope 0.65 to 0.96).
- Intervention effect Soil quality index and ecosystem multifunctionality were significantly higher in mixed forests than in monocultures.
- Observation Mixed forests had higher soil C- and N-acquisition enzyme activities and related nutrients.
- Association In mixed forests, the tree growth index was positively correlated with the soil quality index of A. formosana.
- Association In mixed forests, the tree growth index was negatively correlated with the soil quality index of P. massoniana.
- Observation The growth of A. formosana was more sensitive to available nutrients (nitrate nitrogen, available phosphorus, ammonium nitrogen).
- Observation The growth of P. massoniana relied more on soil total nutrients (total nitrogen and total phosphorus).
- Observation A. formosana had the highest tree growth index, soil quality index and ecosystem multifunctionality in the AAP (2:1) treatment.
- Recommendation A 2:1 (AAP) mixing ratio is recommended for managing P. massoniana and A. formosana mixed forests.
