morphological character

Babao is a perennial herb. The root is carrot shaped. Stem erect, 30-70 cm high, unbranched. Leaves opposite, rarely alternate or 3-impeller-shaped, oblong to ovate oblong, 4.5-7 cm long, 2-3.5 cm wide, apex acute, obtuse, base gradually narrowed, margin sparsely serrate, sessile. Corymbose terminal; flowers dense, ca. 1 cm in diameter, pedicels slightly short or as long; sepals 5, ovate, 1.5 mm long; petals 5, white or pink, broadly lanceolate, 5-6 mm long, acuminate; stamens 10, as long as petals or slightly short, anthers purple; scales 5, oblong cuneate, 1 mm long, apex emarginate; carpels 5, erect, base few separated. The flowering period is from August to October.

Habitat of producing area

It grows on the hillside grassland or ditch side with altitude of 450-1800 M. China's Yunnan, Guizhou, Sichuan, Hubei, Anhui, Zhejiang, Jiangsu, Shaanxi, Henan, Shandong, Shanxi, Hebei, Liaoning, Jilin, Heilongjiang. North Korea, Japan and Russia. Type specimens from Japan.

Growth habit

Babao Sedum likes strong light and dry, well ventilated environment, avoid rain, waterlogging and ponding. In the shade, most of them grow poorly, the plants are not luxuriant, and the branches and leaves are slender and sparse. Strong cold resistance, can withstand - 20 ℃ low temperature. It can grow normally in plain sandy soil, sandy slope soil and light clay, but it grows best in moist, fertile and permeable sandy loam. It can grow normally in the soil with pH value of 8.7 and salt content of 0.2%.

Mode of reproduction

cuttage

Generally, cutting is used. Because the variety is easy to survive, it can be directly cut and watered in the nursery, and the survival rate is higher by spraying new high fat film. Cutting propagation speed, simple operation, so it is more commonly used. Cuttings can be selected from April to August as cuttings. The cuttings are 5-10 cm long, with 2-3 leaves reserved. The incision should be flat and smooth. Cuttings should be collected and placed in the shade. After the incision is dry for one day, cuttings should be placed in the substrate after disinfection treatment. The spacing between plants and rows is 6 × 10 cm. If the substrate is kept moist, cuttings can survive. Transplanting can be carried out in the next year.

Ramet

Before sprouting in early spring, dig out the roots of the plants, divide them into several small plants according to the size of the plants, and plant them into the planting holes prepared in advance and applied with base fertilizer, so as to keep the soil moist and survive.

cultivation techniques

Basin soil

The soil requirements are not strict, but the general basin soil should be mixed with garden soil, coarse sand and humus soil to ensure the soil permeability. Potted plants can be placed in the place with sufficient light to keep the leaf color dark green. We should not water too much in the growing season, and master the principles of "between dry and between wet" and "rather dry than wet". It is better to water after the surface of basin soil is completely dry, avoid mixing water in basin, otherwise it is easy to cause root rot and disease. Potted plants can be changed every 2-3 years.

watering

The first year of planting. Watering should be based on the principle that the soil is moist without ponding. Sufficient water can ensure the survival of seedlings and can be divided into two parts. Generally, it can be watered once a month from April. In rainy days in summer, ponding should be removed in time to prevent root rot due to ponding. In autumn, the water should be controlled to prevent the excessive growth of plants. At the end of autumn, we should pour enough and thoroughly the antifreeze water. In the early spring of the next year, we should pour the thaw water in time. The later management can determine the amount of water according to the soil moisture content, so as to keep the soil in the state of more than half moisture content. Sufficient water should be given during the growing period, especially in summer and autumn. Besides keeping the basin soil moist, water should also be sprayed on the leaves to cool and moisturize.

apply fertilizer

Babao Sedum likes fertilizer, and appropriate amount of farm manure should be applied as base fertilizer when planting. In the late autumn of the planting year, after cutting the aboveground part, apply cow and horse manure once on the planting ground, with a thickness of about 5cm. This fertilizer is not only conducive to the safe overwintering of plants, but also can make the seedlings turn green in advance. From the second year, N, P, K compound fertilizer can be applied once in early summer. It is not suitable to apply a large amount of nitrogen fertilizer to Sedum babaoense, otherwise it is easy to fall down and affect the ornamental. According to the needs of plants, fertilization should be reasonable. Spraying huahuazhuangdiling at the right time can make the buds strong, petals large, flowers colorful, flowers fragrant and flowering period prolonged.

trim

If it grows too fast or too high, it can be pinched properly. If yellow leaves appear, it can be pruned in time to control its growth height and speed. All the above ground parts can be cut off before winter.

Pest control

The common pests are aphid, scale insect and whitefly. If it happens, in addition to strengthening daily maintenance, enhancing ventilation and light transmission, drug auxiliary prevention and control should also be carried out. In case of aphids and scale insects, it can be manually scraped or washed with soapy water when the insect situation is light, and it can be sprayed with 6% imidacloprid EC 3000-4000 times or 1.2% kuyan EC 800-1000 times when the insect situation is serious. In case of whitefly damage, it can be controlled with 3500 times 48% lesben EC.

The common diseases are root rot and coal pollution. Root rot is mainly caused by poor drainage and long-term excessive soil moisture. Therefore, drainage should be timely after heavy rain. If there is any disease, apply the pathogen 1500 times to spray or irrigate the disease. Or 80% 40% EC 1500 times irrigation root, once every 7 days, continuous application of 3-4 times, can effectively control the disease. The pathogen overwinters on the diseased parts and fallen leaves with mycelium, conidia and cotyledons. If high temperature and humidity, poor ventilation and honeydew secreted by aphids and scale insects will aggravate the disease. In case of disease, it is necessary to control aphids and scale insects in time, prune plants, strengthen ventilation and light transmission, or spray 50% carbendazim wettable powder 1000 times solution or 1:1:160 equivalent Bordeaux solution.
