Acer rubrum cuttage and seedling culturing method

Abstract

The invention discloses an acer rubrum cuttage and seedling culturing method. The acer rubrum cuttage and seedling culturing method comprises the following steps: (1) preparing a cuttage medium; (2) selecting cutting slips; (3) treating before cutting; (4) transplanting the cutting slips; (5) managing after cutting. The cuttage medium prepared by the invention has a plurality of good physiochemical properties including better air permeability, porosity, moisture and fertilizer retaining capabilities and the like; a lower-layer medium for growth and an upper-layer medium with heat-insulation, moisture-keeping and antibacterial performances, which are separately arranged, meet a growth principle of cuttage strips, so that the survival rate is improved; before cuttage, the cutting slips are immersed for two times so that the growth speed of roots is greatly improved and the rooting time is shortened; the cutting slips start to take roots 6-9 days after the cuttage and all the cutting slips can take roots after 25 days; the average root quantity is more than 12 and the survival rate of the cutting slips is also up to more than 93%; seedlings have developed root systems, are ordered and strong and have stable properties, so that the economic values are higher.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for raising seedlings of American red maple cuttings.
