Hedgehog, also known as artichoke, wild pheasant, false locust, and large leafhopper, is a perennial herb of the genus Eryngium of the Umbelliferae family. With aromatic stomach, qi and pain, driving the wind to relieve the effect of the table. According to analysis, each 100 grams of fresh product contains 1.44 milligrams of carotene, 2.33 milligrams of vitamin B2, and 33 milligrams of vitamin C. The edible parts are mainly stems and leaves with a special fragrance. Mainly for spices, but also for food or soup. Medicinal herbs are available throughout the year, fresh or dried.
First, the morphological characteristics
Hedgehog plant height 10 to 60 cm, with a special aroma. Basal leaves lanceolate or oblanceolate, with margins of hard bone and spinous teeth, and no petiole. Calyx erect, stout, dichotomously branched, with stem leaves. Most flower heads form cymes, white or light green flowers, seeds are very small, brown.
Second, the growth environment and distribution
Hedgehog thermophilic, heat-resistant, fear of frost, hi wet, drought, yin. The optimum temperature for growth is 15 to 35°C, and it can be safely overwintered at 5°C or above, and the short-term 40°C high temperature plants can grow normally. All kinds of soil can adapt, planted in fertile sandy loam more easily obtain high yield. The seedlings that grow in poor soil are thin but have a stronger aroma. Distributed in Guangdong, Guangxi, Hainan, Yunnan and other provinces and regions, growing in the field edge, behind the house, roadside, wilderness. Artificial cultivation or development of potted plants is now in progress.
Third, cultivation points
1. The breeding method. There is seed breeding and ramification breeding. Seedlings can be seeded in batches from March to October, with 50 grams per 667 square meters. Due to the slow growth during seedling stage, it is recommended to use nutrition or pot seedlings until 4 to 5 leaves are planted. The trifoliate propagation is to cut and transplant lateral buds and fibrous roots that occur on the rhizome of the mother plant. The planting spacing is 30 cm x 20 cm, and 10,000 plants are planted per 667 m2. Immediately after planting, root water was poured.
2. Field management and pest control. After maitaining and planting, 667 to 2,000 kg of mature manure water will be applied every 667 square meters. After 20 days, the second fertilizer will be applied for the second time. Each kilogram of potassium sulphate ternary compound fertilizer of 30 kg will be applied to the water, or the cultivating cover will be applied after dry application. Earth watering. If weeds are picked up or removed during growth. Hedgehog rarely causes disease. However, when there is little sunshine, fog shines, and there is a lot of sunshade, powdery mildew can occur, and 15% of triadimefon can be used to spray 1000 times of water. Insect pests are mainly locusts, and they can be treated alternately with dichlorvos, chlorfenapyr, anti-indoles, and quinones. In case of high temperature and dry weather, frequent spraying of water can reduce locust damage.
