对南酸枣、西南桦、团花、高阿丁枫、红木荷、山桂花和云南拟单性木兰 7个树种进行了苗木施肥试验 ,结果表明 :复合肥能明显提高各树种苗木的苗高、地径和生物量 ,其中以施用 1%复合肥的效果最佳 (但生产中还应因树种而定 ) ,一般以 0 5 %～ 1 0 %为宜 ;尿素对这些树种苗木的生长也有促进作用 ,尤其是对南酸枣、西南桦、红木荷等树种的增长效果更为显著 ,生产中用量以 0 3%～ 0 5 %为宜 ;钙镁磷肥在这些树种的育苗生产中不宜采用。合理施肥能缩短苗木出圃时间 ,一般可提前 1～ 2个月出圃。
The results showed that the compound fertilizers could obviously improve the seedling height of each tree species seedlings, the seedling height, the seedling height, Soil diameter and biomass, of which the best application of 1% compound fertilizer (but the production should also be due to tree species), generally 0 5% ~ 10% is appropriate; urea on the growth of seedlings of these species also contributed to Especially for the growth of southern tree jujube, southwest birch, mahogany and other tree species. The amount of 0 3% ~ 0 5% is suitable for production. Calcium magnesium phosphate should not be used in the seedling production of these species. Rational fertilization can shorten the nursery out of nursery time, usually 1 to 2 months in advance nursery.
