Abstract

The invention discloses a method for propagating roses, and belongs to the technical field of flower propagation and cultivation. The method for breeding the roses comprises the following steps: step 1: collecting rose branches in the middle of 2 months to 3 months, obliquely cutting the cutting slips, reserving 4-8 buds for each cutting slip, enabling the distance between the uppermost bud and a top cut to be 2.0cm-3.0cm, and enabling the length of each cutting slip to be 15cm-25 cm; step 2: soaking the cut for 5-10min by using a potassium permanganate solution with the mass percentage concentration of 0.2-0.5% to obtain a treated cutting shoot; and step 3: filling the nutrient medium into a cutting container; and 4, step 4: and (3) inserting the treated cutting slips into the nutrient medium of the cutting container, wherein the insertion depth is 5-6cm, thoroughly watering, and placing in a plastic greenhouse. The rose propagation method can form callus in 7-10 days, can root in 8-12 days, and has root length of 1-3cm in 15-20 days and survival rate of over 90%.

Description

Rose propagation method

Technical Field

The invention relates to a method for breeding roses, and belongs to the technical field of flower breeding and cultivation.

Background

Roses (academic name: Rosa rugosa Thunb.), China in origin. Belongs to Rosales, Rosaceae deciduous shrubs, branches and stems with multiple needle pricks, odd feathers and compound leaves, 5-9 lobules with oval shape and edge pricks. The petals are inverted egg-shaped, heavy petals to half heavy petals, the flowers are purple red and white, the fruit period is 8-9 months, and the flowers are oblate.

The rose integrates appreciation, medicinal and edible functions, has the effects of activating the depressed vital energy, relieving the spleen, stimulating the menstrual flow, activating blood circulation, beautifying and beautifying, and has special effect on treating cardiovascular and cerebrovascular diseases. With the improvement of living standard of people, the demand of the market for roses is more and more, and particularly, the situation of short supply and short demand appears in recent years.

The existing rose planting method comprises a seeding method, a cuttage method, a grafting method, a layering method and a plant division method, and mainly comprises the cuttage method. The rose branches with leaves are treated by growth hormone and then are cut in sandy soil, but the existing method has the problems of low survival rate and the like.

In view of the above, there is a need to develop a new method for propagating roses to solve the deficiencies of the prior art.

Disclosure of Invention

The invention aims to solve the defects of the prior art and provides a method for breeding roses. The rose propagation method can form callus in 7-10 days, can root in 8-12 days, and has root length of 1-3cm in 15-20 days and survival rate of over 90%.

The technical scheme for solving the technical problems is as follows: a method for propagating roses comprises the following steps:

step 1: collecting rose branches in the middle of 2 months to 3 months, obliquely cutting the cutting slips, reserving 4-8 buds for each cutting slip, enabling the distance between the uppermost bud and a top cut to be 2.0cm-3.0cm, and enabling the length of each cutting slip to be 15cm-25 cm;

step 2: soaking the cut for 5-10min by using a potassium permanganate solution with the mass percentage concentration of 0.2-0.5% to obtain a treated cutting shoot;

and step 3: putting the nutrient medium into a cutting container, wherein the height of the nutrient medium accounts for 2/3 of the height of the cutting container;

and 4, step 4: and (3) inserting the treated cutting slips into the nutrient medium of the cutting container, wherein the insertion depth is 5-6cm, thoroughly watering, and placing in a plastic greenhouse.

On the basis of the technical scheme, the invention can be further improved as follows.

Further, in step 3, the nutrient medium is prepared from the following raw materials in parts by weight: 10-20 parts of corn straw powder, 12-20 parts of molasses, 10-20 parts of wood chips and 10-20 parts of bone meal.

Further, in step 3, the nutrition isKMnO with the mass percentage concentration of 0.5-0.7% is used for the substrate before being filled into a cuttage container₄The solution is sterilized.

Further, in the step 4, the temperature in the plastic greenhouse is 25-28 ℃, the air humidity is 40-50%, and the pH of the soil is 5.5-7.

The invention has the beneficial effects that:

(1) the rose propagation method can form callus in 7-10 days, can root in 8-12 days, and has root length of 1-3cm in 15-20 days and survival rate of over 90%.

(2) The method is simple, has wide market prospect and is suitable for large-scale popularization and application.
