江苏海岸带造林特困地育林新技术的研究

Study on the new technology of forestation in the poorest land of Jiangsu coastal area

根据江苏海岸带造林特困地盐多肥少、风害潮灾、土旱地瘠的特点 ,以I 6 9杨为造林树种 ,对海岸带造林特困地的造林方法、配套技术、管理措施等方面进行了较为深入的试验和研究 ,形成了海岸带造林特困地高产优质高效简化育林新技术。即在海岸带造林特困地上 ,扦插造林不但可操作性强 ,而且造林成本低 ;扦插造林前对插穗用保水生根杀虫剂处理 ,造林成活率可达 85 %左右 ;扦插时辅施棒肥 ,可长效地促进林木高生长和径生长 ;

In accordance with the situation of being windy and tidal,with more salt,less fertilizers,dry and impoverished soils in the poorest land in the coastal area of Jiangsu,a new simple technology of forestation with high quality,output,efficiency has been worked out.This technology has been used for Populus deltoides March.'Lux'which is planted as the forestation tree,and a further research has been made in the forestation methods,skills and management in the poorest soil in the coastal area.Cuttage planting in the poorest soil not only is practical,but also costs less.The cutting should be treated with pesticide and water conservation for striking root before cuttage,the survival rate of the forestation reaches about 85%.Clavated fertilizer when cuttage can promote the growth of trunk.The measures for tending the young growth can be simplified as covered with plastic film and grass.
