The main points of propagation of the flower of Potentilla frutescens

Ditang flowers are native to North and South China. They like warm, semi-shady places and are not strict with the soil. It can be propagated by dividing plant, cutting and sowing, and it is suitable for double-petal varieties. The editor would like to introduce to you the common breeding methods of Ditang flowers.

Ditang flower

First, the key points of rapid propagation

In spring, one-year-old branches are used as in vitro materials for rapid propagation, which can be propagated directly in the intelligent nursery bed. In the growing season, semi-lignified shoots of the same year are used as in vitro materials to retain the upper 1 / 2 leaves, or one leaf and one bud. It is propagated in the nursery bed based on river sand or perlite, and the rapid propagation intelligent system is opened, and the survival rate is up to 100%.

2. Ramets

It is often used in double-petal varieties after defoliation in autumn and before sprouting in spring. The main method of propagation is ramet propagation, and the mother plant does not need to be dug out. In early spring and late autumn, a knife or shovel was used to split the new plant with 1 Mur2 branches from the mother plant directly in the soil and take out and transplant the mother plant left in the soil, and then split again in the second year. Double-petal Tripterygium is suitable for ramet breeding.

Third, cuttage

Cut softwood cuttings in the rainy season, cut them in early spring, and use hardwood cuttings (March) with unsprouted annual branches. In the rainy season, use softwood cuttings around June, use sturdy branches of the same year, leave half of the leaf cuttings long 12-450px, cut in brown soil, ripe soil or sandy soil, if inserted in the open field to shade, to prevent drying.

Fourth, sowing seeds

It is suitable for single-petal varieties and germinates about 20 days after sowing. The method of sowing and propagation is only used in the mass propagation of single-petal original seeds. After harvesting, the seeds should be stored in 5 ℃ low temperature sand for 2 months, and then sown in the next spring. After sowing, cover fine soil, cover grass, and set up a shed for shade after emergence.

The introduction of the flower, the culture method of the flower and the conservation knowledge of the flower.

Ditang flower, alias bee tang flower. The flowers of Diantang can be planted in the ground or potted. There are two varieties of Diantang flower, one is double Diitang flower, the other is Bai Ditang flower. The petals of the former are heavily shaped like a small ball and have ornamental value. Bai Ditang flowers are relatively rare and are highly respected by the Japanese. Now let's learn how to grow Diantang flowers.

Morphological characteristics of the flower of Tripterygium

Tripterygium is a deciduous shrub, 1-2 m high, sparse up to 3 m; branchlets green, cylindrical, glabrous, often arched, twigs angled. Leaves alternate, triangular-ovate or ovoid, apex long acuminate, base rounded, truncate or puberulent, margin acutely doubly serrate, both surfaces green, upper glabrous or sparsely pilose, lower pilose along veins or vein axils; petiole 5-10 mm long, glabrous; stipules membranous, banded-lanceolate, ciliate, caducous. Single flower, inserted at the top of current year's lateral branches, pedicel glabrous; flower 2.5-6 cm in diam.; sepals ovate-elliptic, apex acute, apiculate, entire, glabrous, persistent when fruiting; petals yellow, broadly elliptic, apical depressed, 1-4 times longer than sepals. Achenes Obovate to hemispherical, brown or dark brown, surface glabrous, wrinkled. The flowering period is from April to June and the fruiting period is from June to August. Leaf blade ovate to ovate-lanceolate, 2 mi 10 cm long and 1.5 mi 4 cm wide, apex acuminate, base rounded or puberulent, margin sharply doubly serrate, surface glabrous or sparsely pubescent, abaxially or along leaf veins, pubescent between veins.

The Ecological habits of the Flower of Potentilla frutescens

Ditang flower prefers warm, humid and semi-shady environment, has poor cold tolerance and lax requirements on soil, and grows best in fertile and loose sandy loam soil, which is born in hillside shrubs at an altitude of 200-3000m. Ditang flower originates from North China to South China, likes warm, humid and semi-shady environment, has poor cold resistance and lax requirements on soil, and the fertile and loose sandy loam soil grows best. The propagation methods of ramet, cutting and sowing are commonly used. Ramet is suitable for double varieties. The cuttings are divided into hardwood cuttings in spring and tender wood cuttings in plum rainy season. The flowers of Diantang can be planted in the ground or potted. Transplanting or changing pots should be carried out before spring germination (February to March) or October, with lodging soil. When transplanting, base fertilizer should be applied to promote more new branches and more flower buds.

The Propagation Mode of the Flower of Potentilla paniculata

Potentilla frutescens flowers are propagated by ramet, cutting and sowing.

Key points of rapid propagation

In spring, one-year-old branches are used as in vitro materials for rapid propagation, which can be propagated directly in the intelligent nursery bed. In the growing season, the semi-lignified shoots of the same year are used as in vitro materials to retain the upper 1-2 leaves, or one leaf and one bud. Multiply in the nursery bed based on river sand or perlite, open the rapid propagation intelligent system, and the survival rate is up to 100%.

Ramet

It is often used in double-petal varieties after defoliation in autumn and before sprouting in spring. The main method of propagation is ramet propagation, and the mother plant does not need to be dug out. In early spring and late autumn, the new plants with 1-2 branches were separated from the mother plant directly in the soil by knife or shovel, and the mother plant left in the soil was taken out and transplanted, and then split again in the second year. Double-petal Tripterygium is suitable for ramet breeding.

Cuttage

Cut softwood cuttings in the rainy season, cut them in early spring, and use hardwood cuttings (March) with unsprouted annual branches. In the rainy season, use softwood cuttings around June, use sturdy branches of the year, leave half of the leaf cuttings 12-450px long, cut in brown soil, ripe soil or sandy soil, and shade in the open field to prevent dryness.

Sowing seeds

It is suitable for single-petal varieties and germinates about 20 days after sowing. The method of sowing and propagation is only used in the mass propagation of single-petal original seeds. After harvesting, the seeds should be stored in low temperature sand for 1-2 months at 5 ℃ before sowing in the next spring. After sowing, cover fine soil, cover grass, and set up a shed for shade after emergence.

That's all I know about Ditang today. I hope it will be helpful for flower friends to read this article. If you want to know more about Ditang, please continue to follow the succulent flower bed, we will provide you with more related knowledge!

The Culture method of Diantang Flower Disease Control of Diitang Flower

Ditang golden flowers full of trees, unique grace, in addition to ornamental, but also can be used as medicine to reduce swelling, relieve pain, relieve cough, aid digestion and other functions. Then how to raise the flowers of Ditang? Let's take a look at the culture methods of Ditang flowers.

First, the culture method of the flower of Diitang.

The flower of Diitang sprouts in the middle of March, and it is generally appropriate to transplant before budding. After planting, attention should be paid to pruning dead branches and old branches. During the growing period, fertilization was applied once every 2 months and renewed every 2-3 years to cut off the aboveground parts and promote more new branches. When cultivated in the north, the soil needs to be cultivated in winter to prevent the shoot from withering.

The method of propagation of Diantang flower is propagated by means of ramet, cutting and sowing.

1. Key points of rapid propagation: one-year-old branches are used as in vitro materials for rapid propagation in spring, which can be propagated directly in the intelligent nursery bed. In the growing season, the semi-lignified shoots of the same year are used as in vitro materials to retain the upper 1-2 leaves, or one leaf and one bud. Multiply in the nursery bed with river sand or perlite as the substrate, open the rapid propagation intelligent system, and the survival rate is up to 100%.

2. Ramet: often used in double-petal varieties, after falling leaves in autumn to before sprouting in spring. The main method of propagation is ramet propagation, and the mother plant does not need to be dug out. In early spring and late autumn, the new plants with 1-2 branches were separated from the mother plant directly in the soil by knife or shovel, and the mother plant left in the soil was taken out and transplanted, and then split again in the second year. Double-petal Tripterygium is suitable for ramet breeding.

3. Cutting: cutting softwood cuttings in Meiyu season, cutting in early spring, cutting with hardwood (March) with unsprouted annual branches. In the rainy season, use softwood cuttings around June, use sturdy branches of the year, leave half of the leaf cuttings 12-450px long, cut in brown soil, ripe soil or sandy soil, and shade in the open field to prevent dryness.

4. Sowing: suitable for single-petal varieties, sprouting about 20 days after sowing. The method of sowing and propagation is only used in the mass propagation of single-petal original seeds. After harvesting, the seeds should be stored in low temperature sand for 1-2 months at 5 ℃ before sowing in the next spring. After sowing, cover fine soil, cover grass, and set up a shed for shade after emergence.

II. Prevention and control of flower diseases of Tangeria chinensis

1. Yellow leaf disease: the first symptom is that the top of the plant is slightly tender and the leaf tissue turns yellow or light yellow, but the leaf vein is still green. with the aggravation of the disease, the whole leaf turns yellow or yellow-white, and the leaf margin becomes grayish brown and dies.

Prevention and treatment: at the initial stage of the disease, the root can be irrigated with 200 times of ferrous sulfate solution, and sprayed with 0.5% ferrous sulfate solution, once every 10 days, continuously irrigated and sprayed 3 times for 4 times, which can significantly change the symptoms.

2. Symptoms of brown spot disease: in the early stage of the disease, there were grayish brown disease spots on the edge of the leaves, irregular expansion of the disease spots, grayish brown inside, reddish brown edges, and dry, brown, black granules in the later stage of the disease.

Prevention and treatment methods: spray 75% chlorothalonil wettable granules 800 times or 70% mancozeb wettable particles 400 times or 50% carbendazim wettable particles 500 times, once every 11 days, for 3 times continuously for 4 times to effectively control the disease.

The above is the culture method of Diitang flower. I hope it will be helpful to everyone. Friends who like it can try to plant some.
