摘要：

A study was established in the Virginia Piedmont to investigate the effects of site preparation treatments (subsoiling and trenching) and the use of weed mats on royal paulownia survival and growth. Seedlings were monitored in three study blocks for seven years. Following the seventh growing season, survival was low, ranging from 11% in the control plots to 27% in the trenched plots. Plot volume index averaged 28,633 for the subsoil plots, while control plots had an average plot volume index of 12,685. Weed mats significantly increased soil moisture from 18.7 to 20.4%. Likewise, weed mats significantly improved seedling survival after seven years, from 9% to 30%.
