Embodiment 1

[0019] A method for hybrid cultivation of Chinese roses with large flowers, comprising the following steps:

[0020] (1) Preservation of pollen: Select bright-colored and large-bodied flowers in the Chinese rose, which have high pollen content and activity. Use sterile conical flasks to collect the pollen of the Chinese rose, and store it after baking to obtain preserved pollen. ;Periodic cooling can avoid damage to pollen activity caused by excessive temperature difference. Low temperature method can effectively prolong pollen storage time and activity, have more selection opportunities for pollination time and conditions, and improve pollination success rate;

[0021] (2) Activation: Store the preserved pollen at 9°C for 1.5 hours, then store it at 19°C for 2.5 hours to restore the activity of the preserved pollen, and use the activation solution to atomize it for 22 minutes to increase the moisture content in the pollen. The amino acids, vitamins and other ingredients conta...

Embodiment 2

[0032] The present embodiment 2 is compared with embodiment 1, and the step change is mainly in the following aspects:

[0033] For the baking described in step (1), the temperature is 41° C. and the time is 37 minutes.

[0034] The storage method described in step (1) is as follows: first lower the temperature to -4.5°C for 3 hours, and then lower the temperature to -14°C for long-term storage.

[0035] The activation solution described in step (2), wherein the mass parts of each prepared component are:

[0036] 75 parts of water, 17 parts of corn juice, 8 parts of yeast extract, 4.7 parts of vitamin C, 4 parts of folic acid, 0.38 parts of sodium selenate, and 0.19 parts of gibberellin.

[0037] Step (2) activation, the method is:

[0038]The preserved pollen was placed at 11°C for 2 hours, then stored at 20°C for 3 hours, and sprayed with an activation solution for 24 minutes.

[0039] The transparent plastic bag described in step (3) has two vent holes at the bottom, and...

Abstract

The invention discloses a method for hybridized cultivation of big floral Chinese roses. The method is characterized by comprising the following steps: (1) pollen preservation: selecting bright-colored, and big Chinese roses, collecting the pollen of the luxuriant Chinese roses by using a sterile conical flask, baking the pollen, and then preserving the baked pollen; (2) activation: performing preservation in the environment with a temperature of 18-20 DEG C, and performing atomization treatment by using activation liquid; (3) pollination treatment: spraying 75% ethanol to the big floral Chinese roses so as to be sterilized, performing pollination, parcelling the pollinated Chinese roses with a transparent plastic bag, then spraying the activation liquid, and performing bagging for culturing; (4) hybridization: performing pollination hybridization respectively on the pollen of the luxuriant Chinese roses and the pollen of the big floral Chinese roses with hybridized big floral Chineseroses; and (5) intraspecific breeding: putting the fourth generation of seeds in a greenhouse so as to be planted at a constant temperature, and performing intraspecific pollination after blooming.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese roses with large flowers, and in particular relates to a method for hybrid cultivation of Chinese roses with large flowers. Background technique [0002] The big flower fragrance rose, also known as the giant flower rose, is a seasonal flowering variety. It has a variety of flower colors, strong plants, elegant and beautiful flower shapes, many bright and lively colors, strong aroma and ornamental value, and its flowers can also be used It is used as raw material for perfume extraction and has high economic value. However, the flowering period of the large-flowered rose only blooms once a year in spring and summer. Compared with other rose varieties that bloom every season, the number of flowering times is small, and the flower yield is low. The high-altitude environment of 1400-1700m is not suitable for planting in plain areas, and its planting area is limited, and large-scale planting ...
