摘要
采用L1(645)正交试验设计进行有机肥和复合肥2因素各含4个水平的试验,了解其对西南桦苗木生长的影响。结果表明:(1)苗龄150d和210d时,有机肥、复合肥和二者的交互作用均极显著地影响西南桦苗木地径和苗高的生长。有机肥和二者的交互作用对苗木生长呈现极显著的负效应,单施复合肥即可达到促进西南桦苗木生长的目的;(2)有机肥和复合肥的16种配施中,单施复合肥50g/m2的平均地径和苗高在2个苗龄时均极显著地较其他配施的大,分别为0.96mm(210d)和6.7、9.8cm;(3)影响苗木生长的最佳配施为A1B(2有机肥0kg/m2、复合肥50g/m2),即单施50g/m2的复合肥是促进西南桦生长的最优配施,最优的理论配施和实际试验结果相一致。
The L16（4^5）orthogonal design was applied to implement 2 factors with each including 4 levels of organ- ic fertilizer and compound fertilizer. The purpose was to understand the influences of fertilizations on seedling growth of Betula alnoides. The results showed that： （1）There were significantly different effects of organic fertilizer, compound fertilizer and their interaction on seedling growth of basal diameter and heights for 150 and 210 days＇ old seedlings, the base diameter （BD）and heights of seedlings had a active response to. Organic fertilizer and their interaction were significantly presented a negative effects on the seedling growth, which indicated that Only compound fertilizer could promoted the seedling growth; （2）Among 16 treated combination, the sole fertilization of 50g/m^2 compound fertilizer had basal diameter of 0.96mm （210d）and the heights of 6.7 and 9.8cm for 150 and 210 days＇ old seedlings,which were extremely larger than other treated combinations;（3）The optimal fertilizer combination was AIB2 （organic fertilizer： 0kg/m^2 with compound fertilizer 50g/m^2）, in terms of only compound fertilizer of 50g/m： could promote seedling growth of B. alnoides. The optimal treated combination in theory and practice was the consistent in the experiment.
