摘要
以N、P、K肥为基肥，采用单因素随机区组设计，对西南桦幼林进行施肥试验。结果表明：在基肥施用量为0-200g／株的范围内，树高和地径的生长量均随着基肥量的增加而增大；不同基肥施用量的处理间树高和胸径均存在极显著差异，树高和地径生长较好的处理均是基肥施用量为200g/株的处理，树高和地径生长较差的处理均是不施肥的处理。
i Using single factor randomized block design to carry out the fertilization experiments on sapling of Betula al- noides with N, P, K fertilizer as basal manures. The results showed that： tree height and diameter growth were with the increase of amount of base fertilizer increased in the range of basal fertilizer was 0 ~ 200 g/plant; different basal fertilizer treatment had significant differences in height and diameter growth, better treatments is the amount of basal fertilizer 200 g/plant, and poor treatments is not fertilization.
