The breeding method of large flower geranium and the breeding method of geranium burst pot, geranium cutting method and time

The main results are as follows: (1) sowing and reproduction can be sowed in spring and autumn, and indoor pot sowing in spring is better. The optimum temperature for germination is 20-25 ℃. The geranium seed is not large, the soil cover should not be deep after sowing, and it will germinate after about 14-21 days. It will sow in autumn and blossom in the summer of the following year. After sowing and propagation, excellent intermediate varieties can be selected and bred.

(2) Cuttage propagation can be carried out except that the plant is in a semi-dormant state from June to July. It is better to use spring and autumn. High temperature in summer, cuttings are easy to blacken and rot. Cuttings long 10cm, the top part is the best, vigorous growth, fast rooting. After cutting the cuttings, let the cut dry for several days, form a thin film, and then insert it into the sand bed or the mixed matrix of expanded perlite and peat, be careful not to hurt the bark of the cuttings, otherwise the wound will rot easily. After cutting, the cuttings were placed in semi-shade, kept at 13: 18 ℃ at room temperature, and rooting at 14: 21 days after cutting. when the roots were 3~4cm long, they could be potted. Soaking the base of cuttings with 0.01% indolebutyric acid for 2s can improve the survival rate and rooting rate of cuttings. Generally, the cuttings blossom after 6 months of cultivation, that is, cutting in January, flowering in June, cutting in October and flowering in February to March of the following year.

(3) tissue culture of geranium can also be propagated by tissue culture. Using MS medium as the basic medium, 0.001% indole acetic acid and kinetin were added to promote callus and adventitious buds, and 0.01% indole acetic acid was used to promote rooting.

Culture methods of geraniums Propagation methods of geraniums

Geraniums, an herbaceous flower, are densely planted in groups of flowers. The colors of geraniums are very bright and they are suitable for potted plant decoration. Geraniums bloom for a long time, so people who like to grow flowers can plant geraniums and have enough time to enjoy them. Now I would like to share with you some methods of breeding geraniums.

Propagation methods of geraniums

I. Propagation of geraniums

The reproduction of geraniums needs to be planted by sowing and cutting. what geraniums need is a reasonable greenhouse environment, and tissue culture can be carried out in spring or autumn. In spring, seeds can be planted at a temperature of about 20 degrees, while geranium seeds may go into semi-dormancy in June and July in autumn, when shrimp seeds are treated before planting.

Second, the watering method of geranium

Geraniums like wet environment very much, so do not have stagnant water, otherwise it will lead to problems such as excessive growth and yellowing of geranium leaves. Geraniums should be watered frequently in summer, and the amount of watering is mainly watered thoroughly each time. Don't water too much in winter. it's best to water it when it's dry.

III. Fertilization methods of geranium

It is best to apply thin fertilizer in the process of growth of geraniums, which can promote the growth of flower buds and add fertilizers such as phosphorus and potassium to help the growth of geraniums. Geraniums begin to dormant in the summer, so stop fertilizing.

Culture method of domestic geranium how to reproduce domestic geranium

Domestic geranium, also known as large flower geranium, foreign butterfly, etc., is a perennial herb of the family Pelargoniaceae, distributed in Africa and Hubei of the Chinese mainland. It has been artificially introduced and cultivated, with a florescence usually from July to August. Let's take a look at the breeding methods of geraniums.

Sowing and propagation of domestic geranium

The sowing and propagation of domestic geranium can be carried out in spring and autumn, and indoor pot sowing in spring is better. The optimum temperature for germination is 20-25 ℃. The geranium seed is not large, and the soil cover should not be deep after sowing, and it will germinate in about 2-5 days. It will sow in autumn and blossom in the summer of the following year. After sowing and propagation, excellent intermediate varieties can be selected and bred.

Cutting propagation of domestic geranium

The cutting propagation of domestic geranium can be cut except that the plant is semi-dormant from June to July, and it is better in spring and autumn. High temperature in summer, cuttings are easy to blacken and rot. The cuttings are 10 cm long, and the top part is the best, with vigorous growth and fast rooting. After cutting the cuttings, let the cut dry for several days, form a thin film, and then insert it into the sand bed or the mixed matrix of expanded perlite and peat, be careful not to hurt the bark of the cuttings, otherwise the wound will rot easily. After insertion, put it in a semi-shaded place and keep it at room temperature for 13-18 ℃. It will take root after 14-21 days. When the root length is 3-4 cm, it can be potted. Soaking the base of cuttings with 0.01% indole acetic acid for 2 seconds can improve the survival rate and rooting rate of cuttings. Generally, cuttings blossom in 6 months, that is, cuttage in January and flowering in June. It was cut in October and flowered from February to March the following year.

Tissue culture of domestic geranium

Domestic geranium can also be propagated by tissue culture, using MS medium as basic medium, adding 0.001% indole acetic acid and kinetin to promote callus and adventitious buds, and 0.01% indole acetic acid to promote rooting. Tissue culture provides a new way for improved variety breeding and repetition of new varieties of domestic geranium.
