Impact of herbaceous competition and drainage conditions on the early productivity of willows under short-rotation intensive culture

摘要: The productivity of trees under short-rotation intensive culture is influenced by herbaceous competition and drainage conditions. During the first year establishment Salixdiscolor Muhl. Salixviminalis L., four weed-suppression treatments were applied to two sites showing different conditions, one well drained other poorly drained. On well-drained site, increased in all plots treatment, whereas on only use a plastic mulch biomass production. mean site was always superior measured except when vegetation controlled mulch. analyses related nutrition revealed that absorbed more nutrients than those site. showed higher uptake potassium S. viminalis, concentration calcium. Our result...
