A Detailed Guide to the Latest Prices and Planting Methods for Himalayan Teasel Seeds
Himalayan teasel, also known as Chuanduan, Longdou, Shuzhe and so on, is a perennial herbaceous plant of the genus Dipsacus in the family Caprifoliaceae (Dipsacaceae). It is distributed across Hubei, Hunan, Jiangxi, Guangxi, Yunnan, Guizhou, Sichuan and other places, growing by ditches, in grassy areas, at forest edges and beside field paths. Its roots are used as medicine and have the effects of promoting blood circulation and reducing swelling, promoting tissue regeneration and relieving pain, mending tendons and setting bones, and tonifying the kidneys and strengthening the lower back. Now let us take a look at the price of Himalayan teasel seeds and its planting methods!
How much does one jin of Himalayan teasel seeds cost?
The price of Himalayan teasel seeds is about 60 to 70 yuan per jin, but prices vary greatly depending on seed quality, place of origin, market and so on. In production, Himalayan teasel is generally cultivated in two ways: direct seeding and seedling transplanting. Places with irrigation conditions generally use direct seeding, while sloping land is planted by seedling transplanting. Direct seeding has low cost, the main root is not prone to branching, and the product quality is good, but it has higher requirements for the land. The seedling transplanting method results in more branching of the main root, but it can make full use of lower-value sloping land and mountain land.
Sowing methods for Himalayan teasel
1. Land selection and preparation: For planting Himalayan teasel, choose sandy loam with deep soil layers and loose soil texture, and field plots with good drainage and irrigation conditions. Irrigate the plot (soak it through) 2 to 3 days before land preparation to ensure soil moisture and ensure seedling emergence.
2. Fertilizing and making beds: For the Himalayan teasel seedling bed, first evenly spread 2000 kg of farmyard manure and 50 kg of compound fertilizer per mu over the plot, then run lines to make beds, keeping the bed surface level and fine.
3. Sowing time: Himalayan teasel sowing includes drill sowing, hole sowing, direct seeding and seedling transplanting, among other methods. Direct seeding is divided into spring sowing and autumn sowing. Spring sowing is generally from late April to May, autumn sowing is from September to October, and in areas at an altitude of 2000 to 3000 m, sowing is generally done from June to July.
4. Sowing method: For direct seeding of Himalayan teasel, use 4 jin of seed per mu; for seedling transplanting, use 20 jin of seed per mu, which can be transplanted to 5 mu of field. Evenly scatter the seeds on the soaked seedbed surface. After sowing, cover with soil until no seeds are visible on the bed surface, water thoroughly, and seedlings will gradually emerge after 15 to 20 days.
Planting methods for Himalayan teasel
1. Thinning to final stand and transplanting: When Himalayan teasel seedlings are 10 cm tall, thin them to a final stand at a spacing of 15×20 cm between plants and rows. The removed seedlings can be used to fill gaps or for transplanting. For seedling transplanting, transplanting begins after the ground thaws in early spring of the following year, at a spacing of 20×25 cm between plants and rows, about 10000 plants per mu.
2. Cultivation and weeding: Weeding of Himalayan teasel is mainly done during the seedling stage. Generally, weed twice in the year of planting, and once each year afterward. Also, compared with other medicinal plants, there are not many weeds in the field, and after the plants close their rows each year, no weeding is needed.
3. Water and fertilizer management: Topdress Himalayan teasel 2 to 3 times. After thinning to final stand, apply 1000 kg of dilute human and livestock manure water per mu, then water after application. During June to July, apply 10 kg of ammonium sulfate per mu. Each year before green-up, apply 3000 kg of barnyard manure in furrows between the rows.
4. Removing flower buds: Plants of Himalayan teasel grown for more than 1 year bolt and flower in July. In order to concentrate nutrients to make the rhizome thick and strong, plants not kept for seed should have their flower stems cut off in time, and plants with overly vigorous leaves may also have some leaves cut off.
5. Disease and pest control: For powdery mildew, spray with 0.2% triadimefon; for root rot, spray with lichuning; for leaf spot disease, control with prochloraz or dimethomorph; for aphids, spray with 40% dimethoate at 1000 times dilution; for black cutworm, spray with 90% trichlorfon crystal at 1000 times dilution or dilute with water and drench the roots.
