Problems solved by technology

However, in the cold northeastern region, due to the extremely low temperature, roses are vulnerable to freezing damage, making the survival rate of rose garden cultivation extremely low
[0003] At present, the main factor restricting the introduction of roses to the north is the occurrence of freezing damage. To prevent garden roses from being damaged by freezing, it is time-consuming, laborious and costly; the covering protection method is cumbersome and costly, and the cold resistance effect is poor; poor effect

Abstract

The invention discloses a cultivation method for improving cold resistance of roses, and belongs to the technical field of plant cultivation. The cultivation method is characterized by comprising thefollowing steps of selecting cultivation lands; preparing cuttage substrates; pretreating cutting shoots; performing seedling raising by cuttage; managing cuttage seedlings; performing transplanting;and performing management before winter. Compared with the prior art, the cultivation method disclosed by the invention has the beneficial effects the cutting shoots are pretreated, so that low-temperature stress training can be effectively performed at the stage when rooting of cutting shoots is the most active, gene expression relevant to cold resistant capacity of the cutting shoots is stimulated, and the cold resistant capacity of the roses can be effectively improved; a cold resistant agent is applied, so that transplanted roses can withstand outdoor cold, and the cold injury rate duringpark cultivation can be reduced; and excessive consumption of nutrients can be reduced through pruning branches, useful branches and leaves of rose flowers can be helped to absorb ample nutrients, andthe rose flowers can pass the winter safely.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation method for improving the cold resistance of roses. Background technique [0002] Rose is an upright clumping deciduous shrub in the family Rosaceae. It has various varieties, rich colors and strong aroma. It is not only a good ornamental flower and garden greening plant, but also a precious Chinese medicinal material and an important raw material for the spice industry and food industry. Rose has strong resistance to retrograde, drought and barrenness, saline-alkali, and is an important resource for the breeding of Rosa ornamental plants. However, in the cold northeastern region, due to the extremely low temperature, roses are vulnerable to freezing damage, which makes the survival rate of rose garden cultivation extremely low. [0003] At present, the main factor restricting the introduction of roses to the north is the occurrence of freezing damage. To ...
