Tiger mouth

Tiger mouth is located in the haitangyu gorge. The narrow plank road suddenly turns sharply, which is very dangerous. It can be said that this is the most dangerous place in Baili gorge. The temperature in "hukou" is very low and the air is cool. In tiger mouth, there are some special scenic spots, such as yixiantian, jinxianxuanzhen, looking back at Guanyin, Tianqiao and so on. In addition, after crossing Haitang Valley and entering Shixuan gorge through plank road, the scenery is another scene.

Acorzonera sinensis (scientific name: < iscorzonera sinensis < / I lipsch. Et Krasch. Ex lipsch.), also known as Huzui, is a perennial herb of Compositae, with a height of 5-50cm. The roots are straight and strong. Stems erect, clustered or solitary, with dense fibrous lacerated sheath like remains at the base, similar to the outer skin of Allium sativum in the field. Basal leaves lanceolate, variable in size, including petioles up to 33 cm in length, up to 4 cm in length and 0.3-5 cm in width. One of the most striking morphological characteristics of Allium tonkinensis is its wrinkled leaf margin. Cauline leaves few, scalelike, lanceolate, semiamplexicaul or adnexal.

It grows in the area of 280m to 2500m above sea level, and generally grows in sand dune, wasteland, hillside, hilly land or under shrubbery. It is endemic to China. Distributed in Jiangsu, Beijing, Hebei, Inner Mongolia, Shandong, Gansu, Anhui, Henan, Liaoning, Ningxia, Shanxi and other places.

The crown hair is dirty yellow, 2 cm long, most of which are feathery, the feather branches are slender, spider like, and the upper end is fine serrated; there are spider like hair rings at the junction of the crown hair and the achene. The flowering and fruiting period is from April to September.

Growth habit

It grows on hillside, hilly land, sand dune, wasteland or shrub forest, with altitude of 280-2500 M. Peach leaf green onion blooms very early, has strong drought resistance, and likes to live alone. Type specimens from Beijing.

It has strong adaptability, likes mild and humid environment, and has strong vitality under drought conditions. After planting, the rhizome can sprout when the daily average temperature is 6 ℃. The suitable temperature for growth was 20-30 ℃; when the temperature dropped below 0 ℃, the aboveground parts withered and the growth stagnated. The suitable soil pH is 6.5-7.5.

geographical distribution

It is distributed in Beijing, Liaoning (Jianchang), Inner Mongolia (Daqingshan, Wulashan), Hebei (Yuxian, Shexian, Cixian, Yixian, Neiqiu, Changli), Shanxi (Tianzhen, Pinglu, Wutai, Yongji, Yuanqu, Xingxian, Zhongyang, Qinxian, Guandishan), Shaanxi (Suide, Qingjian), Ningxia (Yinchuan), Gansu (Tianshui, Xinglong, Minxian), Shandong (Qingdao) Jiangsu (Nanjing), Anhui (Xiaoxian, Chuxian), Henan (Tangyin).

Methods of reproduction

rhizome

The planting period is from late October to the end of April next year, and the best is late autumn. Early planting has fast rooting, more germination and strong roots and buds. Before planting, turn up the rhizome, and the stout one-year-old rhizome is better; the spacing of planting lines is 15-20 cm, and the density is suitable for the head and tail of the rhizome, then cover the soil, and rake repeatedly.

seed

Sufficient water should be poured before sowing, and germination should be carried out 10-15 days after sowing. At the beginning of April, the seedbed should be turned deeply before sowing, and the base fertilizer should be applied at the same time. After finishing and harrowing, the seedbed with a width of 1m and a length of 10-15m should be made. Drill or broadcast, 8-10kg seed per mu, cover 2-3cm fine soil after sowing, cover with a layer of grass curtain, often water, keep the soil moist, remove the grass curtain after emergence. The breeding period is one year.

cultivation techniques

Colonization

It can be planted in early and middle April with 20000-30000 seedlings per mu. The planting land was deeply ploughed in the winter of last year, and ploughed once more before planting to eliminate all weeds and apply enough base fertilizer. It is easy to survive in rainy day or afternoon. After planting, cover the soil tightly to avoid water loss of the root system, and then water it.

Administration

During the growth period, the surface should be kept moist. Water in time in case of drought. In case of heavy rainfall, the accumulated water in the field should be removed to prevent the rhizome from suffocating. After the above ground edible part is harvested, topdressing, spraying and weed removal should be carried out in time.

Pest control

Aphid mainly sucks stem and Ye Zhiye, serious cause yellow stems and leaves, and can be prevented by spraying 40% times 1500-2000 times liquid of Omethoate in the occurrence period. Locusts eat mainly leaves, resulting in holes and holes, and can be controlled by spraying 90% times of dimethoate 800 times in the juvenile stage.

harvest

The young leaves and inflorescences can be picked in spring, and the quality of rhizomes is better from autumn to spring before the seedlings are unearthed. After the rhizome is dug out, the stems, leaves, soil and fibrous roots are removed and sold after drying.

Species difference

At first glance, the flower shape of the green onion is very similar to that of dandelion. Both of them have very obvious terminal yellow flower heads with similar size. The difference is that the number of florets in the former is small and the volume is large, while the number of florets in the latter is small and the volume is small. Secondly, in the former, the involucre of the head is cylindrical, and the involucre is about 5 layers; in the latter, the involucre is usually only inner and outer layers. Thirdly, the total scape of the former is stout, while that of the latter is short, weak and hollow. In fact, the former has few and slender leaves and the latter has short oval leaves. In addition to the leaf shape, the fruit shape is also different. Although the top of the fruit also has a crown hair, like a parachute, but it is mostly wrapped by bracts, rarely as fully developed as dandelion.
