| 中文摘要: |
| 为探索新型液态肥与常规颗粒肥对尾巨桉林分生长的影响,在同等经营管护条件下,分别设
置施用常规颗粒肥与新型液态肥两种施肥处理,通过对施肥后尾巨桉林木进行生长量调查及施肥
效益分析。结果表明,在等养分施肥条件下,施用颗粒肥的成本低于施用液态肥,且尾巨桉平均树
高生长量、平均胸径生长量分别较施用液态肥林木约提高4%~14.9%、6.6%~10.8%。但液态肥
施肥方便快捷,其施肥速度是常规颗粒肥的4~6倍,在任务量大、人工短缺及亟需施肥的前提下,
施用液态肥具有较大的优势。 |
| 英文摘要: |
| The two fertilization treatments, conventional granular fertilizers and new liquid fertilizers,
were applied to the young E. urophylla×
E. grandis, and the growth of trees and the benefits of fertilization
were investigated and analyzed, in order to explore the effect of the two fertilization treatments on the
growth of young E. urophylla×
E. grandis forest. The results showed that under the condition of equal amount
of nutrient fertilization, the cost of applying granular fertilizer was lower than that of applying liquid
fertilizer, and the average tree height growth and average breast height diameter growth amount increase
by 4%-14.9% and 6.6%-10.8% respectively. However, the application of liquid fertilizer was convenien
and fast, with a fertilization rate that was 4-6 times that of conventional granular fertilizer. Under the premise of large workload, labor shortage and urgent need for fertilization, the application of liquid fertilizer
had unparalleled advantages. |
