Urge with cold bed Gen Fa or electric seed bed heater method to carry out urging root cuttage and seedling culture afterwards, cuttings survival rate can be made to 90%；Wei little Li etc.
2007 are reported and are soaked after sturdy narrow hat fast-growing locust tree cutting 30s with 500mg/L IBA, and effect is most in the quartzy casting bed for cuttage
Good, rooting rate reaches 83.2%；Yang Xingfang etc. reports NAA the and IBA mixed processing tetraploid locust with 1000mg/L for 2007
Cutting lower cut, can make survival rate to more than 60%.Autumn husky Tibetan cutting, Second Year spring carry out urging root using hotbed,
Heated by cutting base portion, cutting endogenous growth inhibiting substances content is reduced, insert after urging root in nutritive cube, protected using shed
Wet, allow survival rate to reach 80% or so；Meng Bingnan etc. is hidden through winter sand in report in 2010, in conjunction with when before husky Tibetan with cuttage
2 secondary growth Auto-regulators process, tetraploid locust cuttings cuttage survival rate highest, reach 66.67%；In IBA, NAA and ABT tri-
Plant in the process test of growth regulator, the ABT of 500ppm processes cuttings cuttage survival rate and is up to 71.11%；Wang little Ling etc.
Report within 2012 tetraploid locust cuttage to be advisable with IBA1000mg/L process 6h, highest rooting rate reaches 55.56%.Base
When different locust tree kind cuttage root-takings, the processing mode difference of cuttings is larger, and this may be relevant with locust tree genotype, therefore visits
The condition of rope locust tree cuttage rooting, improves cuttage survival rate, proposes that a whole set of is simple and practical, being suitable for promoting in grass-roots unit should
