Bletilla striata is a kind of Chinese medicinal material. It can also be used to make facial masks and has beauty effects. Nowadays, the demand for Bletilla striata is increasing, and the current Bletilla striata mainly depends on wild species, causing the market to be in short supply. How can this phenomenon be improved? At this time, Bletilla striata can be artificially planted. Do you know how to plant Bletilla striata? Next, let us learn about the Bletilla striata planting technology.
1. Basic information of Bletilla striata
Bletilla striata is the dried rhizome of Bletilla striata, a plant belonging to the genus Bletilla of the orchid family. Also known as white root, ground screw, white chicken baby, sheep's horn, splendens splendens, purple orchid, etc. It is a commonly used traditional Chinese medicine that has the functions of nourishing the lungs, stopping bleeding, reducing swelling and promoting muscle growth. It is mainly used to treat hemoptysis due to tuberculosis, hemoptysis due to bronchiectasis, hemoptysis due to gastric ulcer, hematuria, blood in the stool, etc. It can be used externally to treat traumatic bleeding, burns, and chapped hands and feet. Nowadays, the adhesive film block made of Bletilla striata is used to stick to the incision of liver and spleen surgery to replace blood forceps. It has very good effect and has rapid coagulation effect. It can be used in surgical operations instead of plasma. Mainly produced in Sichuan, Yunnan, Shaanxi, Anhui and Hubei. It is also cultivated in Guizhou.

1. Land selection and preparation
Choose loose and fertile sandy loam and humus loam, a warm, slightly humid environment, and do not Hardy to cold. When planting in well-drained mountainous areas, it is advisable to choose shady slopes for planting in wasteland. Plow the soil over 20 centimeters, apply manure and compost, and apply 1,000 kilograms of farmyard manure per acre. If there is no farmyard manure, you can spread 50 kilograms of ternary compound fertilizer, or 100 kilograms of organic fertilizer. Plow the ground again to mix the soil and fertilizer evenly. Before planting, do a shallow plowing, finely trim the soil, rake it flat, and make a sorghum border 130--150 cm wide.
2. Propagation method
It is difficult to sow Bletilla striata with seeds, but it is easier to propagate it by tubers. When developing in a large area, tissue culture seedlings can be used for propagation. For tuber propagation, Bletilla striata is usually dug out from September to early November, and medium-sized, disease-free tubers with many buds and eyes are selected. Each piece has 1-2 buds, and then planted with plant ash. Dig the trench at a distance of 20-25 cm and a depth of 5-6 cm. Place a tuber at a spacing of 10-12 cm between plants with the buds facing upward. Fill in, compact, water, cover with grass, and keep moist at all times. 3 --Seedlings emerge in April. 100 kg of seedlings per mu.
3. Field management
(1) Cultivating and weeding. Bletilla striata requires strict management and weeding in the field. After planting, spray acetochlor to seal the field, and then the bletilla striata seedlings will emerge. Bletilla striata grows vigorously from May to June, and weeds also grow quickly, so weeding is required. Weeding should be combined with loosening the border surface, and shallow hoeing should be done during weeding to avoid damaging the roots.
(2) Top dressing Bletilla striata is a plant that likes fertilizer. Spray potassium dihydrogen phosphate or thin human and animal excrement once a month. It will stop growing and enter dormancy in July-August, but it is necessary to prevent weeds. Overgrown grass.
(3) Irrigation and drainage. Bletilla striata prefers shade and should always be kept moist. It needs to be watered during drought. Water it once in the morning and evening from July to September. Bletilla striata is also afraid of waterlogging, so heavy rains should be drained promptly to avoid root damage.
4. Prevention and control of diseases and insect pests
(1) Root rot disease mostly occurs in the rainy seasons of spring and summer in the south. Prevention and control methods: Pay attention to drainage and waterproofing, and dig deep drainage ditches.
(2) Cutworms and wireworms can be hunted and killed manually, or mixed with poisonous soil, and the groundworms can be applied to the bed. Pour the bed with 700 times of 50% zinc, sulfur and phosphorus emulsifiable concentrate.
5. Harvesting and processing
After Bletilla striata is planted for 2-3 years, when the above-ground stems wither in September-October, dig out the tubers and remove the soil for processing. Pick off the tubers individually, select the tubers with new stems for seeding, cut off the stems, soak them in clean water for 1 hour, wash the soil, boil them in boiling water for 5 to 10 minutes, and take them out of the kang until they are completely dry. Remove the coarse bark and fibrous roots, and sift out impurities. Generally, 800-1000 kilograms of fresh products are harvested per mu, and 200-300 kilograms can be processed.
Bletilla striata planting technology
Bletilla striata prefers a warm, shady and relatively humid environment and is not cold-tolerant. It often grows wild on the banks of streams and rivers in hilly and low-mountain areas, on hillside grasses and under sparse forests. Therefore, fertile, loose and well-drained sandy loam or humus loam should be selected for cultivation. It is required to be cultivated on shady slopes or relatively humid plots.
