Problems solved by technology

However, the distribution of C. Zhongdian is narrow, the population size and population are small, and the seed propagation is difficult, which greatly limits the protection and development of C. Zhongdian.
[0003] At present, the research on the reproduction technology of Zhongdian thorn rose is still in the initial stage of exploration. Although the seed propagation technology has made some breakthroughs, the seed emergence rate is still not high, and there are few scions suitable for grafting in graft propagation. The width of the thorns affects the flattening of the multi-bud scion and the grafting and binding operation, which makes the multi-bud scion prone to "jumping buds" after grafting, and has poor grafting compatibility with various rootstocks, and the grafting joint takes a long time to grow and heal. The low reproductive coefficient, weak growth potential and poor survival of most grafted seedlings seriously restrict the protection and development of Rosa zhongdian

Embodiment 1

[0023] (1) Cultivation and management of rootstock: in mid-October, plant well-grown Seven Sisters roses with a stem thickness of 0.8-1.2 cm and a length of 15-17 cm in the greenhouse. Plant 4 rows in each row, with a row spacing of 15×20 cm. The rows are planted against the edge of the border, and the plants are planted at an angle of 45-50° to the border. Before planting, apply 500-800 kg of organic fertilizer per acre in the soil, water once 15-20 days after planting, keep the soil moist, and use a compound fertilizer with N-P-K of 15-15-15 to dissolve in water every 40 days. The amount of fertilization per mu is 25 kg; after winter, the greenhouse is kept warm during the day and night, and the temperature at night is kept above 2°C, and the temperature during the day is kept above 10°C; every 30 days, use 1.8% arubicin 1500 times solution to prevent and control spider mites and Aphids once.

[0024] (2) Treatment of broken branches of rootstock: In mid-December, when the ...

Embodiment 2

[0037] (1) Rootstock cultivation management: In early July, the rootstocks were planted in the greenhouse, and the rest were the same as in Example 1.

[0038] (2) Scion selection: At the beginning of July, select new shoots of Rosa japonica with good growth and development as scions. Firstly, the new shoots are topped to promote the enrichment of new shoot tissues and the full development of bud eyes, and cultivate excellent scions. In mid-to-late August, the scions are collected 1-2 days before grafting, and after the scions are collected, they are packaged and transported in low temperature and moisture to prevent the scions from mildew and dehydration.

[0039] (3) Grafting: Grafting and operation method are the same as embodiment 1.

[0040] (4) Management after grafting

[0041] 1) Temperature control: The temperature is relatively high from August to September. Through shading and ventilation to cool down, the night temperature is controlled between 12-14°C and the day...

Abstract

The rootstock folding branch single-bud grafting method of Zhongdian thorn rose is a complete set of Zhongdian thorn rose grafting and breeding method. The seven sisters rose with wide adaptability and applicability is selected as the root stock, and the rootstock is cultivated by adopting the method of folding branches and leaving leaves The vegetative branches provide nutrition and power for rootstock growth and grafted bud growth. Compared with conventional rootstocks without branches and leaves and 2-3 bud grafting, the survival rate of grafting is increased by 28.30%-60.25%, and the reproduction coefficient is increased by 1-2 times; The method bred Rosa chrysalis grows vigorously and can maintain the excellent traits of its parents, which is of practical significance for the preservation, development and utilization of Rosa chrysalis in different places.

Description

Technical field: [0001] The invention belongs to the technical field of plant grafting, in particular to the field of grafting methods of woody ornamental plants, and specifically relates to a rootstock-folded-branch single-bud grafting method of Zhongdian thorn rose in practical technology. Background technique: [0002] Zhongdian Thorn Rose ( R. praelucens Byhouwer) is a unique species of Rosa in my country and a "vulnerable" plant. It is an upright tree-like shrub with bright colors and rich variations. It has high ornamental value and is an important alpine ornamental flower. It is deeply loved by the local people and has great exploit potential. However, the distribution of C. chrysalis is narrow, the population size and population are small, and the seed propagation is difficult, which greatly limits the protection and development of C. zhongdian. [0003] At present, the research on the reproduction technology of Zhongdian thorn rose is still in the initial stage of...
