摘要
设圈肥、复合肥和阿维菌素等3因素3种用量水平的肥料组合,对3月龄柚木播种苗生长的影响进行L9(34)正交试验,结果表明:圈肥是促进苗高生长的主要因素,随着圈肥和复合肥施肥量的增加,柚木苗高生长呈递增趋势;阿维菌素是促进柚木苗地径生长的主要因素,随着阿维菌素和圈肥施用量的增加,柚木苗地径生长呈递增趋势;株施圈肥6 g,复合肥1.6 g·L-1,阿维菌素4 g的组合有利于柚木苗高和地径的生长。
L9（34）orthogonal test of fertilizer combinations with manure,compound fertilizer and abamectin on 3-month old Tectona grandis at three dosages was carried out. The results indicated that manure has played dominant role in promoting seedling height. The more the manure and compound fertilizer, the higher the seedling height. While the seedling ground diameter mostly depends on avermectin. The more the avermectin and manure, the larger the ground diameter would be. The optimum condition for seedling height and ground diameter is in combination of 6 g of manure, 1.6 g· L-1compound fertilizer and 4g of avermectin.
