Seedling raising method of rosa rugosa

Abstract

The invention provides a seedling raising method of rosa rugosa, and belongs to the technical field of seedling propagation. The seedling raising method comprises the steps that ridging and bedding are carried out in a ventilating greenhouse near a water source, the bottoms of soil beds are paved with red bricks, and a treating agent of glycerol and L-proline is applied in a nursery substrate, andthen the mixture is laid on the red bricks; the stem bases of cutting slips are scratched, then soaked in a rooting agent solution containing a garlic extract, taken out, then inserted into activatedcarbon and taken out for cuttage, after cuttage is completed, an automatic intermittent fog device is utilized to spray magnetized water to control the humidity, temperature and light transmittance in the greenhouse, and after 50-60 d, seedling hardening and transplanting can be carried out. The seedling raising method of rosa rugosa has the advantages that the process is simple, rapid and efficient, withering and falling of leaves are effectively prevented, browning and rotting of the roots of the cutting slips are prevented, normal rooting of the cutting slips is promoted, the activity of new root systems is enhanced, the roots are thicker and stronger, and the rooting rate and cottage survival rate of the cutting slips are increased.

Description

technical field [0001] The invention belongs to the technical field of nursery stock propagation, and in particular relates to a rose seedling raising method. Background technique [0002] Rose (scientific name: Rosa rugosa Thunb.): Origin China. Rosaceae, Rosaceae deciduous shrubs, with many needles on the branches, odd pinnate compound leaves, 5-9 leaflets, oval, with side thorns. The petals are obovate, double to semi-double, and the flowers are purple-red and white. The fruit period is from August to September, flat spherical. The branches are relatively weak and drooping with dense thorns, and there is only one flowering period per year, so it is rarely used for breeding. Recently, its main characteristics are disease resistance and cold resistance. When roses are used as economic crops, their flowers are mainly used for food and extraction of essential rose oil, which is used in cosmetics, food, fine chemicals and other industries. [0003] Roses have many functions...

Problems solved by technology

In the method of the invention, the seedling tray is placed on the water bed, which is not only expensive, but also has many inconveniences in management. In addition, a small amount of polyphenol oxidase overflows from the cut of the rose cuttings, which may oxidize the phenolic substances in the roots of the cuttings, causing the Roots of cuttings are browned, rotten or even dead, resulting in a decrease in rooting rate and survival rate
