Jatropha curcas propagating cuttage technique

Abstract

The invention belongs to plant breeding field. The Jatropha curcas breeding cutting technique is to employ hard branch for cuttage and keep seed bed to be wet but not dry. The temperature for cuttage is 25-30 Deg. C, the relative humidity is controlled between 80-90%, and the effective water capacity in soil is 5-10%. The invention overcomes the current technique shortcomings and produces mass and high-quality Jatropha curcas seedling, which can meet large-scale production demand and makes it possible for high added value Jatropha curcas industrial development.
