The invention belongs to the technical field of
plant cultivation, and particularly relates to a preparation method of a
pachyrhizus erosus
cutting slip for cross-region and / or peak shifting cuttage and a
pachyrhizus erosus cuttage
seedling raising method.The method comprises the following steps that in the growth environment with the average temperature being 20-25 DEG C and the average
humidity being 80%-90%, a
pachyrhizus erosus
branch with two
bud points is selected, the distance between the two
bud points is 12-20 cm, and the pachyrhizus erosus
branch with two
bud points is selected; respectively truncating at positions 4-6cm away from the two bud points to obtain
cutting slips containing the two bud points; the morphological lower ends of the cuttings are placed in a
water retention carrier containing a
bacteriostatic agent, then the cuttings are placed in a
water retention appliance, and the
pinto bean cuttings are obtained. According to the preparation method, the high
vitality of the cuttings after long-distance and long-time transportation can be guaranteed, and the highest cuttage
survival rate of pinto beans can reach 95.10%.
