Cultivation : It can be cultivated in open field, potted in greenhouse, cultured in box or hydroponics.
Cultivation time: The suitable cultivation time in Shanghai is from May to November. It can be combined with the control of flowering period. It should not be transplanted in winter or early spring after long leaves. Cold areas should be planted in the spring. Most varieties prefer a warm climate, the highest temperature does not exceed 30 ° C, the average temperature of the day is 24 ° C, suitable for growth of Lycoris. The average daily temperature in winter is above 8 °C, and the lowest temperature is 1 °C, which does not affect the growth of Lycoris.
Cultivation environment : The planting depth should not be too deep, just like the top of the bulb is buried in the soil. Appropriately drained acidic sandy soil or loose culture soil is required. When planting, apply proper amount of base fertilizer and pour water after cultivation. The vegetative growth period should always be watered to keep the soil moist, but not to accumulate water to prevent the bulbs from rot. The right amount of water must be supplied from the 20th day before flowering to the flowering stage to achieve uniform flowering and prolong flowering.
Cultivation method: The Shanghai area can be cultivated in the open field. The small bulbs around the main ball are peeled off for breeding. The roots of the main ball are repaired and dried for two days. After the wound is dry, it can be planted. The cultivated land requires high ground and good drainage, otherwise it should be made into a high ditch and deep ditch to prevent damage. When the row spacing is 15cm×20cm, when the soil is covered, the top of the ball should be exposed to the soil surface. Generally, the fertilizer is applied 2 to 4 times a year. The first time after the leaves are deciduous and before flowering, organic fertilizer or compound fertilizer can be used. To cut flowers, the buds are in need of pre-release. The second time before the flowering period in late October and early November. After the flower is collected, continue to supply water for fertilizer, but reduce the application of nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, and make the bulbs strong and full. After the fall, you should stop the fertilizer and stop the water, so that it will gradually sleep. Dig the ball to choose a sunny day, when the soil is dry, dig up, remove the soil, and store it after drying. It can also be cut off the leaves, and the soil is placed in the greenhouse to sleep. The room temperature is kept at 5 °C ~ 10 °C, the indoors are kept dry, and the air is circulated to prevent the bulbs from rot.
The production method can also adopt 40cm×60cm frame cultivation method, generally 16 balls per basket. The advantages of this method are convenient for transplanting and convenient for maintenance and management. Attention should be paid to weeding in production. Generally, herbicides can be sprayed. When the weeds are too long, the spraying time is generally selected after the leaves and after harvesting.
In addition, potted plants can be used. Generally, large balls that can grow in the field for 3 years and have a diameter of 7 cm or more can be planted in one pot or three to four balls in a large pot. To plant shallow, make 1/3 to 1/2 of the ball on the soil. After the upper basin is watered for 1 time, the soil is slightly moistened, and then watered after the new leaves are issued. Apply liquid fertilizer once every half month. Watering can be stopped when the leaves are thickened and ripe in autumn. After germination from February to March, turn over the basin or replace the potting soil.
The culture soil can be prepared by mixing 2 parts of peat, 2 parts of garden soil and 1 part of perlite, and adding a small amount of base fertilizer. In the summer dormancy period, watering should be less, and in spring and autumn, the soil should be kept moist. During the growing season, the pancake water is applied once every half month. Lycoris is half-yin, avoiding direct sunlight in summer, and keeping it in the semi-yin in spring and autumn. Strictly control watering during the winter and stop fertilizing.
