马尾松不同育苗及处理方式的造林效果试验

试验结果表明：在相同的立地类型及管理条件下，用马尾松营养袋苗造林，可比用１年生大田裸根苗造林成活率提高１０％；幼树当年的地径和树高生长量也大１９％和４４％。马尾松１年生大日裸根苗造林前用钙镁磷处理根部，可促进其当年生长；用３号ＡＢＴ生根粉处理可提高造林成活率。

The Planting Effect Experiment on Different SeedlingRalsing Modes and Treatment Modes of Pinus massoniana

The experimental results show that under the conditions of same site type and management，as compared with adopting 1-year-old field naked-root seedlings of Pinus massoniana the planting survival percent can increase by 10％by adopting the plants of P. massoniana in nutrient bags and the ground diameter and height growth of the saplings also increase by 19％and 44％.respectively in the current year; and the growth of 1-year-old field naked-root seedlings can be promoted in the current year if the calcium magnesium phosphate fertilizer is used to treat the seedling roots before afforestation and their planting survival percent can be raised by using No. 3 ABT rooting powder for treatment.
