不同施肥处理对冷杉苗木生长的影响
Effect of Different Fertilization Treatments on Growth of Abies nephrolepis Seedlings
摘要
Abstract
Fertilization is an important cultivation practice in forestry nursery. Rational fertilization could improve seedling growth state, reduce cost and increase survival rate of seedlings on forestation sites. A fertilization experiment with four treatments including control,foliar fertilizer,(NH4)2HPO4,and manure was conducted to assess effect of different fertilization treatments on the growth of Abies nephrolepis seedlings with 2-year-old. After one growing season,the seedling height was increased by 346% ,249% ,210% and 69% under foliar fertilizer, manure,(NH4)2HPO4,and control treatments,respectively,while the basal diameter was increased by 200% , 140%,128%,and 109% under foliar fertilizer,manure,(NH4)2HPO4,and control treatments,respectively. Compared with control,all fertilization treatments significantly increased the seedling height and basal diameter except that ( NH4)2HPO4treatment did not significantly affect the basal diameter. Seedlings growing under control had a weaker correlation between basal diameter and height than those under manure treatment but stronger correlation than those under foliar fertilization and ( NH4)2HPO4treatments. Our study showed that different fertilization treatments had significantly different effects on growth of Abies nephrolepis seedlings, with seedlings receiving foliar fertilizer having the greatest height and diameter. Fertilization treatments also altered the correlation between height and diameter differently,and the height was more responsive to fertilization treatments than the diameter.关键词
