杨树覆膜扦插育苗试验研究

Experimental Study on Film Mulching and Cutting Propagation of Poplar

摘要:

摘要：采用杨树覆膜扦插育苗技术, 能够有效地抑制杂草生长，杨树成活率提高了12.2%；1年生扦插苗的地径生长量和高生长量分别比对照提高了12.9%和15.5%；苗木出圃质量也得到了提高，其中一级苗提高了10.9%，二级苗与对照大体相当，三级苗则降低10.6%；采用该技术育苗每666.7 m2生产成本降低了220元，而收入则提高了1600多元。

Abstract:

Abstracts:Adopting the technology with film mulching and cutting propagation of poplar,which reduced weed growth，the survival rate of poplar increased 12.2%;The basal diameter growth and height growth increased respectively 12.9%,15.5% compared with the control. The seed quality also increased,including first rate seedlings increased 10.9%, second rate seedling equivalented to control,and third rate seedling reduced 10.6%.The cost reduced 220 Yuan and the income increased 1 600 Yuan per 666.7 m2 by the technology.
