摘要
1999年昆明地区开始批量引种和开发元宝枫,据对引种情况调查:4～5年生大树裸根造林保存率为96.4%,苗木生长良好,无明显的病虫害;昆明地区的最佳播种时间为2月底,播种苗生长量差异显著,通过平茬可以培育干形通直的苗木;叶用林的栽培宜采用1.5 m×2.0 m株行距,该模式叶产量高而投资较少.
Acer truncatum trees have been broadly introduced and cultivated in Kunming area since experiments that the best sowing time for Acer truncatum in Kunming area was by the end of February. The growth difference among seedlings from sowing was remarkable. Saplings with straight trunk and ideal shape might be cultivated by cutting the stems back to stubbles and training the sprouts from scratch. The spacing for leaf- producing cultivation of Acer truncatum in Kunming area was suggested as 1.5 m × 2.0 m, which would yield higher leaf production with less investments.
