ScorzonerasinensisLipsch.etkrasch. Is a perennial herb of Compositae. Plant height 5~10cm, with milk. The root is stout, the root system is dense and thick, fibrous, brown. Stems solitary or 3-or 4-aggregated, glabrous, with powdery. Basal leaves lanceolate or broadly lanceolate, long 5~15cm, glabrous, glaucous, margin deeply wrinkled, apex obtuse or acuminate, base narrowing into winged petiole, base broadly sheathlike clasping; cauline 2-foliolate, scalelike, subsessile, semi-clasping. Capitate inflorescences solitary at stem tip, involucral bracts tubular, long 2~3cm, broadly 8~13mm, outer bracts broadly ovate or triangular, very short, inner bracts lanceolate; ligulate flowers yellow, outer rose, long 20~30mm. Achenes, Terete, long 12~14mm, dark yellow, slightly curved, glabrous, beakless, longitudinally furrowed, crown white, feathery. The flowering and fruiting period is from April to June.

Peach leaves, raven onion tender leaves, young inflorescences edible, delicious; root medicine, with heat-clearing and detoxification, anti-inflammatory, breast-dredging effect.

1 ecological conditions

Peach leaves and scallions have strong adaptability, like temperature and humid environment, and have strong vitality under dry conditions. After rhizome planting, it can sprout when the daily average temperature is 6 ℃. The suitable temperature for growth is 20-30 ℃, and when the temperature drops below 0 ℃, the aboveground part shrinks and dries up, and the growth stops. Peach leaves and scallions are not strict on soil, clay, loam and sandy soil can grow, barren hills, slopes and barren land can also be planted, and the suitable soil pH is 6.5-7.5.

2 methods of reproduction

2.1 the propagation and planting period of rhizome is from late October to the end of April of the following year, and the planting at the end of autumn is the best. Early planting takes root quickly, sprouts more, and the roots and buds are stout. Before planting, turn up the rhizome, and the sturdy 1-year-old rhizome is the best; planting row spacing 15~20cm, the density of the rhizome should be connected from beginning to end, then cover the soil and rake evenly.

2.2 the seeds should be fully watered before reproduction and sowing and germinate 10-15 days after sowing. The seedlings were raised at the beginning of April, the seedling bed was turned deeply before sowing, basic fertilizer was applied at the same time, and after fine raking, the seedling bed was made into a seedling bed with a width of 1m and a length of 10m. Strip sowing or sowing, the amount of seed per mu 8~10kg, after sowing covered with fine soil 2~3cm, covered with a layer of grass curtain, often watered, keep the soil moist, remove the grass curtain after emergence. The seedling period is 1 year.

3 colonization

Peach leaves and scallions can be planted in the first and middle of April, leaving 20,000 to 30,000 seedlings per mu. The planting site was deeply ploughed in the winter of last year, and ploughed once more before planting, removing all weeds and applying sufficient base fertilizer. Generally, it is easy to survive in rainy days or in the afternoon. After planting, the soil is compacted to avoid the loss of water from the root system, and then watered.

4 field management

Always keep the surface moist during the growth of peach leaves and scallions. Water should be watered in time during drought. When the rainfall is heavy, the stagnant water in the field should be eliminated to prevent the rhizome from suffocating to death. After the harvest of the edible part of the aboveground, it is necessary to fertilize, spray and remove weeds in the field in time.

(5) Pest control

Aphids mainly feed on stem and leaf sap, and seriously cause stem and leaf yellowing, which can be sprayed with 40% dimethoate EC 1500-2000 times during the occurrence period; locusts mainly bite leaves, causing lacunae and holes, and can be sprayed with 90% trichlorfon 800 times solution in their infancy.

6 harvest

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