Embodiment 1

[0060] 1. Seedbed preparation: Choose a gentle slope with a leeward slope of about 5° for seedling cultivation, and use loose, fertile, well-drained sandy loam as the seedbed. Clean up shrubs and weeds before freezing in the previous year, and plow the soil deeply (about 40cm) but do not cultivate carefully to let the soil weather and freeze the eggs to death. In mid-January of the next year, first apply base fertilizer and disinfection (farm organic fertilizer 2000kg / mu; Mianlong 6kg / mu), and then crush the soil to make a furrow (1.2m wide, 30cm high, with drainage ditches around, 40cm wide). After watering thoroughly, cover the furrow surface with plastic film, fumigate for 30 days, then remove the film and harrow the ground, and let it breathe for 2 to 3 weeks.

[0061] 2. Selection of cuttings: In early March, select annual branches with vigorous growth, no disease, and axillary buds. Cut off the leaves and cut them into 20cm strips. Make sure that each branch has 2 to 3 ...

Embodiment 2

[0069] Embodiment 2 is basically the same as Embodiment 1, the difference lies in the treatment of the cuttings, specifically: the upper end of the cuttings is dipped in melted wax and capped. Take the fresh fruit and young leaves of Boluo, decoct them with water for 2 times, combine the extracts, filter out the residue after the extracts are cool, add rooting powder ABT to the filtrate to fully dissolve, and make a mixture containing 160mg / L ABT Solution, fine humus and plant ash are mixed in a ratio of 0.8:1 (v / v), poured into the solution, and stirred to form a slurry. The lower end of the cuttings is dipped in the mud to prepare the cuttings.

Embodiment 3

[0071] Embodiment 3 is basically the same as Embodiment 1, the difference lies in the treatment of the cuttings, specifically: the upper end of the cuttings is dipped in melted wax and capped. Take the fruit and young leaves of Boluo, decoct them with water for 3 times, combine the extracts, filter out the residue after the extracts cool down, add rooting powder ABT to the filtrate to fully dissolve, and make a mixed solution containing 250mg / L ABT , Mix fine humus and plant ash at a ratio of 1.5:1 (v / v), pour it into the solution, and stir it into a slurry. The lower end of the cuttings is dipped in the mud to prepare the cuttings.

Abstract

The invention relates to a cutting breeding method for rosa laevigata. The method comprises the following steps that lignified branches of the rosa laevigata are taken and cut into cutting slips withthe length of 15-25 centimeters; the lower ends of the cutting slips are wrapped with mud, wherein the mud adopted for wrapping comprises a macleaya cordata extraction solution, a rooting agent, humusand plant ash, and the volume ratio of the humus to the plant ash is (0.8-1.5):1; the cutting slips wrapped with the mud are inserted into a seedbed; cutting management treatment is performed on thecutting slips inserted in the seedbed, wherein the cutting management treatment involves root watering treatment performed on the cutting slips by using a sterilizing agent, and the sterilizing agentalso contains a macleaya cordata extraction solution. The cutting breeding method for the rosa laevigata has the advantages that rooting is fast, the root system is developed, the occurrence of root rot can be significantly reduced, the survival rate of cutting seedlings is high, and the survival rate of transplanting can be increased.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a method for cutting and breeding of Rosa japonica. Background technique [0002] Rosa laevigata (Rosa laevigata) is a perennial evergreen climbing shrub of Rosaceae (Rosaceae). The leaves are odd pinnate compound leaves alternate, and the leaflets are generally 3 pieces; the flowers are solitary in the leaf axils at the top of the side branches, the petals are white, and the flowering period is 4-4. June; fruit pear-shaped, purple-brown, densely covered with bristles, persistent sepals long at the top and reversed outwards, with many achenes inside. The fruiting period is July-November. Fructus Rosa Rosa is a pioneer plant for rocky desertification control. It is widely distributed in the southern provinces of my country. It grows on sunny hillsides, beside fields and in shrubs by streams. It has no strict requirements on soil and is resistant to cold and drought. Rosa ...
