The cuttage and seedling culture method of American red-maple

The invention belongs to seedling-wood breeding technical field, relate to the cuttage and seedling culture method of a kind of American red-maple, parent semi-lignified branch then is selected to be cut into the cuttage branch of 8 10cm length, retain 23 buds, 24 blades, the upper end of cuttage branch cuts flat, away from top bud 1 1.5cm, bottom is tiltedly cut, clip smooths, cuttage branch is inserted in the perlite after inserting sterilization treatment after soaking 12 hours in culture fluid and turfy soil mixed-matrix, stay in and can carry out naked transplanting after perlite and turfy soil mixed-matrix are cultivated 40 45 days.The perlite that cutting medium of the present invention uses weight ratio to be 5:1 and turfy soil mixed-matrix, its breathability, good hygroscopicity, low cost, beneficially root growth, rooting rate is high；Using soaking technology, make cutting root have the time of abundance to absorb the nutrient in nutrition, in cuttage to mixed-matrix, within 40 45 days, can carry out naked transplanting, survival rate can reach more than 95%, and the seedling cycle is short.
