Pasture varieties - Puna chicory

I. Botanical characteristics: Puna chicory is a perennial herb of the Asteraceae family. Its main root is thick and thick, with roots of 20-30 centimeters, leaf length 20-40 centimeters, width 4-7 centimeters, dark green leaves, and tender texture. In the first year of growth, the stems can be stemmed and flowered, and the flowering height can reach 1.6 to 2.0 meters. The flowers are blue heads.

Biological characteristics: Puna chicory is a perennial forage, with long growth life. Under good field management, the amount of grass production is high. Fresh grass is produced from 4,000 to 7,000 kilograms per 667 square meters for a period of up to 8 months (4 ~ November); adaptability, strict requirements for the soil, dry land, wasteland can be planted, hi warm and humid climate. Drought-resistant, cold-resistant, salt-tolerant; soft stems and leaves, white milk after breaking off, good palatability, cattle, sheep, pigs, fish, rabbits prefer food; resistance to pests and diseases; , after the death of easy rotten root.

Third, cultivation techniques: Pina chicory seed is small, should pay special attention to the cultivation of seedlings, so before sowing requires a fine site preparation, per 667 square meters of fermented organic manure applied 2500 to 3000 kilograms as a base fertilizer; sowing is best to use fine sand and The seeds are mixed so as to spread evenly; the sowing time can be sowed in spring and autumn, and if it is mainly castrated green forage, it can be sown in March to April or July to October. If the harvested root is dominant, it should be in July. Sowing in the middle and late is appropriate.

Fourth, field management: Generally 5 days after sowing can be Qimiao, this time to pay special attention to the timely application of quick-acting nitrogen fertilizer, spraying urea 13 kg per 667 square meters, in order to promote the rapid growth of seedlings. In addition, the chicory is afraid of earthworms. The water in the ground must be drained in time. Watering, fertilizing, and controlling grasses and early pests and diseases in time can generally cause normal growth. However, watering and topdressing should be timely after each castration in order to promote regeneration of stems and leaves.

Fifth, forage use: Pueraria chicory is soft, good palatability, nutrient-rich, cattle, sheep, pigs, fish, rabbits like to eat, protein content between 16.44% ~ 27.35%. Suitable for use when drawing stems 40 to 80 cm, because the stems and leaves are fresh and the protein content is high. When the castration is used, the height of the earthworm is 4-6 cm, and it can be cut once in about 30 days. Puna chicory can be freshly fed, green-fed and made into dry powder, and it can also be mixed with alfalfa to prepare for winter and spring use.
