1. Choose fresh and full Emilia sonchifolia seeds for sowing and seedling raising. Before sowing, make the ground thin, firm and flat, water it, and sow after the soil is slightly dry. Use 500g seeds every 667m2, and cover with a thin layer of fine sand after sowing. Be careful not to cover it too thick, otherwise it will affect the emergence rate. Always keep the seedbed moist in the future. If conditions permit, it is best to raise seedlings in greenhouse.
2. Plant in sandy loam with good drainage, 3-6 days before planting, apply 2500kg of decomposed manure every 667m2, and apply urea and ternary compound fertilizer *** 10kg as base fertilizer, so that the border is 20cm high, 90cm wide and 30cm wide. Water the seedlings 2 hours before transplanting, bring as much soil as possible when transplanting, and then plant according to the row spacing of 20cm ×20cm. Immediately after planting, water the roots.
3. Field management It takes 20 to 30 days to pick Emilia sonchifolia after planting, and attention should be paid to prevent grass shortage and soil hardening during this period. In the process of growth, the soil should be dry and wet alternately, and the soil moisture content should not exceed 60% when wet. After picking, apply urea and ternary compound fertilizer at the ratio of 3: 1, with the concentration of 0.5%, and loosen the soil frequently. When I found bloom, I was about to pick it. There are fewer pests and diseases of Emilia sonchifolia, and only aphids are harmful. Once found, 40g pesticide (imidacloprid content is 10%) or pesticide spray can be used per 667m2. Rust is the most harmful, and it can be controlled with 1500 times triadimefon EC after it is found. A little red, afraid of water accumulation. When it rains, it must be drained in time, otherwise it will greatly affect the output.
4. Generally, the tender stems and leaves of Emilia sonchifolia can be harvested and marketed after the plant width reaches 15cm. If the environment is suitable, it can be harvested 1 time in 4 days, with a yield of 1500kg per 667m2, and the harvesting period is as long as 4 months.
(British) Emilia Herb is also known as Hongyexia, Leymus chinensis and Hongyebei. The source is the whole grass of DC little red.

Born in Shan Ye, roadside and village. Location: Guangdong, Guangxi, Fujian, Guizhou and Jiangxi. Harvest in summer and autumn, wash and dry, or cut into sections when fresh and dry. Chemical components contain trace amounts of hydrocyanic acid, alkaloids and phenols. It tastes cold and slightly bitter. Function: clearing away heat and toxic materials, diminishing inflammation and promoting diuresis. Can be used for treating enteritis, dysentery, urinary tract infection, upper respiratory tract infection, conjunctivitis, oral ulcer and carbuncle.
