摘要
河北杨扦插采用窑藏催芽与土埋催芽处理对比,地膜覆盖和大田不覆盖对比,结果表明:窑内沙藏催根处理插穗和地膜覆盖,可提高扦插苗的高、地径生长量和扦插成活率,缩短育苗周期,提高产量。
HeBei poplar cutting contrast test by sand storage in the tunnel of the kiln and soil burial,plastic film mulching and not covered in field were conducted,the results showed sand storage and plastic film mulching could increase growth and survival rate,shorten the raise seedling period.
