Feicai is a perennial herbaceous plant belonging to the genus Sedum of the Crassulaceae family. Feicai is also called cabbage, soil notoginseng, sedum notoginseng, and Jinbuhuan. In addition to being edible and ornamental, Feicai can also treat cardiovascular disease. It has the effect of treating diseases, so it is cultivated in all parts of the country. The editor below will introduce the cultivation techniques and propagation methods of Sedum sedum.
Cultivation technology of Sedum sedum sedum
Sedum sedum is also known as sedum notoginseng. It is rich in nutrients. Long-term consumption has good effects on heart disease, high blood pressure and hyperlipidemia. Very therapeutic and effective. And the method of growing sedum is simple, so sedum is a health-care vegetable that many people grow. The editor below will introduce the cultivation technology of sedum. Let’s take a look at what issues should be paid attention to when cultivating sedum?
1. Temperature management
Feicai likes warm climates and is not frost-resistant. Its growth slows down under the scorching sun in hot summer. In early spring, late autumn and winter, solar greenhouses or greenhouses plus small sheds and straw thatch can be used for cultivation. The daytime temperature is kept at 15 to 30°C. If it exceeds 32°C, ventilation and cooling are required. The nighttime temperature is kept above 5°C, and the relative humidity is controlled at 65 %~75%. Generally, the shed film is covered in late October when the temperature drops significantly. At this time, the temperature is not very low. Ventilation can be large during the day and the air vents can be closed at night. After December, cover with thatch to keep warm at night. After the beginning of spring, gradually increase ventilation as the outside temperature rises, and remove thatch in early April. In summer and early autumn, it is mainly covered with sunshade nets to prevent high temperatures and heavy rains, which can increase production and improve quality.
2. Watering and fertilization management
Fertilizer is very drought-tolerant, but sufficient water supply is beneficial to the growth of stems and leaves, increasing yield and Improve quality. Water thoroughly after planting and keep the border moist at all times. Watering should follow the principle of "seeing dryness and seeing wetness". Generally, in early spring and winter low temperature seasons, the principle of "no watering without drought, watering with small amounts of water" should be followed, combined with watering a small amount of quick-acting fertilizer. Watering should be frequent during periods of high temperature and drought, and waterlogging should be drained promptly during flood periods or after heavy rains. Water should not accumulate in ditches to avoid root rot. During the low temperature period of overwintering, just keep the soil moist. Do not make it too wet, let alone accumulate water, otherwise it will easily cause root rot. About 15 days after planting, seedling fertilizer should be applied topically. Generally, 5 to 10 kg of urea is applied to 667 square meters to promote multiple branches. Fertilizer is a vegetable whose stems and leaves are harvested multiple times. It is best to apply fertilizer and water once every time it is harvested. Apply 10 kg of urea or 15 kg of organic compound fertilizer to 667 square meters each time.
3. Cultivating and weeding
In the year of planting, regular cultivating to loosen the soil can promote the early growth of vegetables and increase the yield of the year. After each watering or after heavy rain, cultivating and weeding must be carried out to promote vigorous plant growth.
Commonly used propagation methods of Feicai
The artificial planting and propagation methods of Feicai can be used for seed propagation, division propagation and cutting propagation. However, because the seeds of Feicai are relatively small, the germination rate is also low. If it is used for production, it is generally not recommended to propagate by sowing, and propagation by division is the main method. The editor below will introduce the breeding methods of Feicai.
1. Seed propagation
Feicai is generally sown in greenhouses to raise seedlings in mid-to-late March when the temperature is stable above 10℃. . Before sowing, apply 3,000 kilograms of decomposed organic fertilizer to the seedling border of 667 square meters, and then prepare the seedling border with a width of 1.2 meters. Pour the seedbed thoroughly with water, sow the seeds while they are still wet, and then cover them with 0.2 to 0.5 cm of fine soil. Pay attention to heat preservation and moisture after sowing. Keep the temperature at 25 to 30°C during the day. Ventilate and cool down when it reaches 32°C. 8 to 10 days after sowing. Seedlings are ready to emerge. When the seedlings are 5 centimeters high, combine cultivating and weeding, remove thin seedlings, and keep the spacing between seedlings 2 to 3 centimeters; water appropriately during the seedling stage and keep the border surface moist at all times. When the seedlings are about 100 days old, 10 to 15 centimeters tall, and have 5 to 6 true leaves, they can be planted in the field. The cabbage cultivated in facilities does not bloom because the young stems and leaves are continuously harvested. Seed propagation is generally not used in production.
2. Propagation by divisions
Propagation by divisions is usually carried out in late March. Dig up the roots of the cabbage, select strong plants for division, and cut them into several plants. Each cut root section should have as many root buds as possible to shorten the seedling slowing time, and then plant it in the seedbed or planting hole. Water to keep it moist. The survival rate of ramet propagation is high and the method is simple, but the propagation coefficient is low, so it is suitable for small area production and propagation.
3. Propagation by cuttings
The plant has strong tillering ability, the stems are fleshy and bushy, the fleshy roots are hypertrophic, and the plant height is 25 to 40 cm. The cutting propagation technology of Feicai is easy to operate, not only has a high survival rate, but also the seedlings grow robustly, so this method is often used in production.
1. Cutting propagation time. The temperature in spring and autumn is relatively suitable, and the growth of vegetables is relatively vigorous. Seedlings are usually propagated by cuttings from March to April and August to September. diyju.com
2. Selection of seed strains. When propagating by cuttings, you should choose strong branches that are free from diseases and insect pests and have a certain degree of maturity.Cuttings from branches that are too young or too old.
3. Seedbed preparation. Phyllanthus is generally cut from a seedbed and then transplanted to the field after survival. This not only facilitates seedling management, but also greatly improves the survival rate of the cuttings. The seedbed must be prepared before cutting, and a sandy soil plot with high dry terrain, good drainage, deep soil, fertile and loose soil should be selected as the seedling seedbed. Before the seedlings are raised, 2,000 to 3,000 kilograms of decomposed high-quality organic fertilizer is spread on the 667-square-meter seedbed. The land is plowed deeply and finely, and then a seedling border is made with a furrow width of 25 cm, a border height of 20 cm, and a border surface of 100 cm.
4. Seed plant treatment. Select the full segments in the middle and upper parts as cuttings. Leave 2 to 4 nodes on each cutting, about 10 cm long. Leave 2 to 3 leaves on the upper end of the cutting. Cut off the lower leaves and put the cuttings on the prepared seedbed. In order to improve the survival rate of cuttings, tie 50 selected branches into a handful before cutting, and then soak the base in a rooting powder solution with a concentration of 50 mg/kg for 12 hours, or in a naphthaleneacetic acid solution with a concentration of 20 mg/kg. Soak for 15 to 20 minutes, or soak in an indolebutyric acid solution with a concentration of 15 to 30 mg/kg for 15 to 20 minutes.
5. Cuttings. Open cutting trenches on the seedling bed with row spacing of 10 cm. The trench depth is 4 to 5 cm. Cuttings should be made in 10 rows per row. Insert the cutting seedlings into the cutting trench of the seedbed with a spacing of 5 cm between plants. The appropriate depth of penetration into the soil is 3 to 5 cm.
6. Cutting seedbed management. After cuttings are taken, the cuttings should be watered immediately and attention should be paid to heat preservation and moisturizing; for spring cutting propagation, a small shed should be covered for heat preservation and moisturizing, and the daytime temperature should be kept at 20 to 30°C; for propagation in summer and autumn, due to high temperatures, heavy rain, and humidity If it is large, it should be covered with a sunshade net to protect it from rain and sun.
