Today's focus is to introduce the best time to sow Bletilla striata seeds and the cultivation and management techniques of Bletilla striata, as well as some knowledge about flowers and plants. Next, the site editor will introduce to netizens.
Bletilla striata is a plant of the Orchidaceae family, also known as Lianji grass, Gan root, Baiji, Zhu lan, Zilan. It is a commonly used traditional Chinese medicine with the functions of replenishing the lungs, stopping bleeding, reducing swelling, and promoting muscle growth. It is mainly used to treat symptoms such as hemoptysis due to pulmonary tuberculosis, hemoptysis due to bronchiectasis, hematemesis due to gastric ulcer, hematuria, and hematochezia; externally used for traumatic bleeding, burns and scalds, and cracked hands and feet.
Morphological characteristics: Bletilla striata is a perennial herb, 30-60 cm tall, with fleshy corms, white, with 2-3 lobes in a rhombic shape, with fibrous roots, often several growing together. The raceme is terminal, usually with 3-8 flowers; the flowers are light purple-red, with irregular petals. The capsule is cylindrical, with 6 longitudinal ridges, slightly pointed at both ends. The seeds are small and numerous. The flowering period is April to May, and the fruiting period is July to August. There are two types of Bletilla striata, one with yellowish white flowers and linear-lanceolate leaves is called narrow-leaf Bletilla. Among the purple-red flowers, there are large and small varieties, with the large variety having higher corm yield.
Growth characteristics: Bletilla striata prefers a warm, cool, and humid environment, is not cold-resistant, and requires fertile, loose, and well-drained sandy loam or humus soil. It is cultivated on shady slopes or relatively humid land.

Cultivation techniques:
1. Land selection and preparation
Select loose and fertile sandy loam and humus soil, warm and slightly humid environment, not cold-resistant. For planting on well-drained mountainous land, choose shady and fallow land. Plow the soil to a depth of over 20 cm, apply barnyard manure and compost, apply 1000 kg of farmyard manure per mu, and if there is no farmyard manure, apply 50 kg of ternary compound fertilizer. Then turn the soil to mix it with the fertilizer evenly. Cultivate shallowly before planting, fine-tune the soil, rake it flat, and make high ridges 130-150 cm wide.
2. Propagation methods
Bletilla striata is difficult to propagate by seed, but it is easier to propagate by dividing corms. From September to early November, dig up Bletilla striata, select medium-sized corms with many buds and no disease, each with 1-2 buds, dip in wood ash, and plant. Make trenches 20-25 cm apart, 5-6 cm deep, place one corm at a time at a distance of 10-12 cm, with the buds facing up, fill in, press down, water, cover with straw, and keep moist. Seedlings emerge in March to April. Use 100 kg of seedlings per mu.
3. Field management
① Weeding: Bletilla striata requires strict weeding in field management. After planting, spray Ethametsulfuron to seal, and after the seedlings emerge. In May and June, Bletilla striata grows vigorously, and weeds also grow quickly, so weeding should be done. Combine weeding with loosening the ridge surface, and shallow hoeing should be done to avoid damaging the roots.
② Timely topdressing: Bletilla striata is a plant that likes fertilizer, and spray monopotassium phosphate or diluted animal waste once a month. From July to August, it stops growing and enters dormancy, but care should be taken to prevent weed overgrowth.
③ Irrigation and drainage: Bletilla striata likes shade and should be kept moist. Water should be provided during dry spells, with two waterings in the morning and evening in July to September. Bletilla striata is afraid of waterlogging, so timely drainage should be performed after heavy rain to avoid root damage.

Disease and pest control:
1. Root rot disease: Common in the southern region during the rainy season from spring to summer. Control methods: Pay attention to drainage and waterproofing, dig deep drainage ditches.
2. Cutworms and wireworms: Can be manually captured and lured or mixed with poisoned soil, and apply Dipterex to the bed. Use a 50% zinc sulfate emulsion 700 times solution to water the bed.
