摘要
Experiments on spaying Penzhangjing on seedlings ofLarix leptolepis was conducted for a year. The height growth and diameter at foot of experimental seedlings increased by 34.3% and 35.5%, respectively, compared with control seedlings. Variance analysis concludes that Penzhangjing have obvious effect on growth of height and diameter at foot of seedlings.
