切根育苗对马尾松苗木及幼林生长的效应

Effects on Growth of Nursery Stock and Young Crop of Pinus massoniana by Cutting Roots When Growing Seedlings

    摘要
  • 摘要: 马尾松种子经沙床催芽后育苗,芽苗截根定距移栽,不同切根处理、不同深度切根、切根苗造林等试验表明:马尾松育苗采取芽苗截根定距移栽,9月初苗期切主根和侧根,切根深度8~10cm,苗木质量最优,造林成活率可达96%;幼林生长各项指标最好,并提前郁闭成林,降低成本,经济效益显著.

     

    Abstract: Seeds of Pinus massoniana were germinated in sand bed to grow seedlings and bud seedlings by cutting roots were transplanted in definite distance.Nursery stocks by cutting roots with different measures and to different depth were planted.The results showed that by cutting their roots and side roots to the depth of 8~10 cm early in September, the seedlings could acquire nursery stocks with best quality, the plantation survival rate of 96%, the best growth indexes for young crop, canopy closure ahead of time, lower cost and significant economic benefit.
