It is also known as the perennial herbaceous plant, bellflower, which is a perennial herb of the family Eustomaceae. It is rooted in human medicine and has the functions of declaring lungs, dispersing cold, expectorant, purulent, wild in the hillsides and grasses. The soil for planting eustoma is mostly loam, sandy loam, clay loam, and humus loam. The soil should not accumulate water, the soil has too much water, and the roots are easy to rot. Bellflowers are afraid of wind damage. Planting in windy areas should pay attention to preventing wind damage and avoid lodging. All provinces in North and South China have production.
Bellflowers are mainly propagated by seeds, seeded for direct seeding and seedling raising. The live broadcast has straight roots, few branch roots, and better quality than seedlings. The live broadcast is divided into winter broadcast and spring broadcast. Take winter sowing as early as possible. 11 月初，在做好的畦上按 20 ～ 25 厘米行距开 1 厘米深浅沟，将种子撒入沟内，覆土盖平，然后镇压一次，上冻前浇一次冻水，第二年春出苗。 Sowing in winter, at the beginning of November, open a 1 cm deep and shallow trench with a row spacing of 20 to 25 cm on the prepared hoe. Spread the seeds into the trench, cover with soil and flatten it, then suppress it once, and pour frozen water once before freezing. . 4 月中旬，浙江于 4 月上旬。 Spring sowing in Beijing in mid-April and Zhejiang in early April . 50 ℃温水中，随即搅动至水凉后，再浸泡 8 小时，用湿布包上，放在 25~30 ℃的地方，上面用湿麻袋片盖好，进行催芽。 In order to make the seedlings tidy, the seeds must be treated. The seeds are placed in warm water at 50 ℃, then stirred to cool in water, and then soaked for 8 hours. Okay, let's germinate. 4 ～ 5 天，待种子萌动时即可播种，方法同冬播。 Rinse with warm water once a day in the morning and at night , about 4 to 5 days. When the seeds sprout, you can sow them in the same way as in winter. 10~15 天出苗，每 666.7 米 2 播种量 4 千克。 Watering after sowing, often keep the soil moist before emergence, emergence about 10-15 days, 4 kg per 666.7 m 2 seeding . 1.3 米宽苗床，长度不限，畦土要松软细碎，按 10 厘米行距开 1 厘米深浅沟条播，将种子均匀播入沟内，覆土 1 ～ 1.5 厘米，播后经常保持土壤湿润。 Choose a sunny and sheltered place for seedling cultivation, apply sufficient base fertilizer, level the rake, and make a 1.3- meter wide seedbed of unlimited length. The soil should be soft and finely divided, and seeded at a depth of 1 cm in shallow trenches at a row spacing of 10 cm. Inside, the soil is covered by 1 to 1.5 cm, and the soil is often kept moist after sowing. 1 5 天出苗，苗高 3 ～ 5 厘米时，间去过密和细弱的苗。 Seedlings emerge in about 15 days. When the height of the seedlings is 3 to 5 cm, excessively dense and weak seedlings are occasionally removed. 5 ～ 7 厘米左右，按 5 厘米株距留苗。 The height of the seedlings is about 5 to 7 cm, and the seedlings are kept at a distance of 5 cm. After that, the grass is plucked, and it will be planted in the field after autumn or before the next spring. 25 ～ 30 厘米、株距 7 ～ 10 厘米栽植，栽时顶芽以上覆土 2 厘米。 Plant in rows of 25 to 30 cm and plant spacing of 7 to 10 cm. Cover the soil with 2 cm above the top buds . When planting in the south, the soil is moist and may not be watered. In the north, especially after spring planting, the soil must be watered with the planting and watering, and the soil should be loosened immediately when the wet and dry conditions are suitable to prevent the ground from cracking and causing wind and dead seedlings. 3 ～ 5 厘米时结合松土除草，把过密的幼苗拔掉，待苗高 7 ～ 10 厘米时，按株距 7 ～ 10 厘米定苗，经常中耕除草，保持地内疏松无杂草。 In the live broadcast site, weeding with loose soil when the seedling height is 3 to 5 cm, and pull out the over-dense seedlings. When the seedling height is 7 to 10 cm, set the seedlings at 7 to 10 cm, and weed and weed frequently to keep the ground loose and free of weeds. . 20 厘米时，每 666.7 米 2 追施过磷酸钙 20 千克，硫酸铵 12.5 千克，在行间开沟施，施后松土，把肥料埋严浇水， 6 ～ 7 月开花时，再追施粪稀一次。 When the height of the seedlings is 20 cm, 20 kg of superphosphate and 12.5 kg of ammonium sulfate are applied every 666.7 m 2. Trench the soil between the rows, loosen the soil after application, bury the fertilizer and water it tightly . Topdressing dung once. Combine soil loosening before the rainy season to prevent lodging. In case of drought after the seedlings are set, you can properly water them. Do not make the ground water in the rainy season and strengthen drainage to prevent rotten roots.
Harvesting and processing
Harvest in the second and third years after sowing. At present, Hebei, Shandong and other provinces can also be harvested for one year. Harvest before spring sprout or late autumn. Remove the stems, leaves, and soil. Use a bowl or a bamboo knife to scrape the outer skin. The skin must be fresh, preferably after planing. , Root bark is not clean and dry quickly. Then wash and dry, remove the head of the reed, moisten the slices and dry for later use. 4 元，主要用于做成菜，用量极大。 At present, Korean merchants purchase fresh eustoma in China at 4 yuan per kilogram , which is mainly used to make vegetables, and the amount is extremely large.
