Bletilla striata, its tubers have white flesh. It is a common Chinese herbal medicine with various medicinal effects. Artificial cultivation is practiced in many areas. Let’s learn about the methods and techniques of white and artificial cultivation.

Land preparation and fertilization

According to the growth habits of Bletilla striata, Bletilla striata should be planted in a warm and cool environment, and ensure that the soil has good porosity, high humus content, and good drainage. Before planting Bletilla striata, prepare the land first, add 75 kilograms and 1700 kilograms of compound fertilizer and decomposed agricultural fertilizer respectively, mix them thoroughly with the soil, and smooth the land.

Breeding methods

Bletilla striata should be planted with holes according to the row spacing. The standard row spacing is generally 15cm×20cm, and the hole depth is generally 10cm. Additionally, divisions can be used for propagation. Choose large varieties of purple flowers and saffron white dolphins, cut thick tubers, and have 1 to 2 buds per plant. Dig holes 1.5 inches deep throughout the border, spacing 5 inches between rows and 4 inches between plants. Place seeds in each hole, cut 1 piece off, cover 1 inch, press lightly after planting and water immediately. The seeding rate per acre is 40 to 50kg.

Intercropping weeding

In the first two years of Bletilla striata planting, the annual weeding frequency should be 4-6 times. After the young leaves of Bletilla striata seedlings emerge, observe them at any time and weed them manually in time. The use of chemical herbicides should be prohibited because these herbicides usually contain toxic and harmful substances that are not conducive to the maturation of Bletilla striata tubers and even cause poisoning of Bletilla striata tubers, which will greatly reduce yield and quality.

Water and fertilizer management

Keep the soil moist before emergence. After the seedlings emerge, water them during periods of drought. When the seedlings are 1 inch tall, apply 15kg of ammonium sulfate per acre and water after top dressing. White, not tolerant to high temperatures, intercropped with corn on the ridge for shade. When the weather is hot in summer, well water should be poured to cool down, and attention should be paid to drainage to prevent water accumulation and root rot.

Pest and Disease Control

Before Bletilla striata grows young leaves, it should be made into poison and spread on the Bletilla striata planting ground, so that it can kill the larvae. The proportion of poison should be 0.5kg 50 phoxim emulsifiable concentrate, add appropriate amount of water, spray into 150kg fine soil and mix thoroughly. During the control period, a 1000-fold solution of 90 crystalline trichlorfon can be sprayed on the ground.

The common diseases of Bletilla striata are mainly root rot. In the early stage of the disease, 100-150ml of Bacteria solanacearum can be used, mixed with 30ml of garlic oil, and sprayed regularly, about once every three days, continuously. 2-3 times. Black spots can also appear in Bletilla striata plantings. Use 1000 times of thiophanate 70 methyl wet powder to spray on the leaves of Bletilla striata for control.

The above is an introduction to the artificial cultivation of Bletilla striata. Bletilla striata is usually harvested before and after "frost", the tubers are dug out, large tubers are selected for medicinal purposes, small tubers are planted, stored in a non-freezing room, buried in the basement with sand or placed in a cellar. As a traditional Chinese medicine in high demand, Bletilla striata still has good planting benefits. If conditions permit, planting can be considered.
