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1 600多元。
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 respec- tively 12.9%,15.5% compared with the control. The seed quality also increased, including first-rate seedlings in- creased 10.9%, second-rate seedling equivalented to control, and third-rate seedling reduced 10.6%. The cost re- duced 220 Yuan and the income increased 1 600 Yuan per 666.7 mz by the technology.
