The new energy plant Jerusalem artichoke is full of treasure
The Jerusalem artichoke (Helianthus Tuberosus L.) , also known as Muntjac, is a perennial root herbaceous plant. 1-3 m high, with massive underground stems and fibrous roots. Stems erect, branched, White short-hispid or setose. Leaves usually opposite, petiolate, but upper leaves alternate; lower leaves ovate or ovate-elliptic. Inflorescences large, few or many, solitary on branches, with 1-2 LINEAR-LANCEOLATE BRACTS, erect, ligulate flowers usually 12-20, yellow tongue, spreading, oblong, tubular corolla yellow, 6 mm long. Achenes small, Cuneate, with 2-4 hairy conical flat awns above. Florescence 8-9 months. Native to North America, it was introduced to Europe in the 17th century and later to China. Its underground tubers rich in starch, Inulin and other fructose polymers, can be eaten, cooked or porridge, pickled pickles, drying Jerusalem artichokes, or for making starch and alcohol raw materials. The planting in the vicinity of the dwelling house has both beautifying effect. Jerusalem artichoke has been described by Food and Agriculture Organization of the United Nations officials as a 21st century crop for both humans and animals. Jerusalem artichoke is a perennial plant, 1-3 m high. Tuberous rhizome. Stems erect, branched distally, shortly hispid or setose. Basal leaves opposite, upper leaves alternate; Petiole, Petiole narrowly winged distally; Leaf Blade Ovate * Elliptic, 10-15 cm long, 3-9 cm wide, apex acute or Acuminate, base broadly cuneate, margin serrate, upper rough, lower pilose, with 3 veins. Inflorescences several, arising from shoot tips, 5-9 cm in diameter, with 1-2 linear-lanceolate bracts; involucral bracts Lanceolate or linear-lanceolate, spreading; ligulate flowers neuter, yellowish, especially conspicuous; tubular flowers bisexual, cloudy, Corolla Yellow, Brown or purple, splinter five. Achenes Cuneate; crests often 2-4 flattened awns hairy distally. Flowering Period 8-10 months. According to tuber skin color can be divided into red skin and white skin two varieties. Jerusalem artichoke is cold-resistant and drought-resistant. Tubers Germinate at 6ー7 °C, sprout at 8ー10 °C, seedling can endure 1ー2 °C, Sunshine at 18ー22 °C and 12 H is favorable for tuber formation. Tubers can survive the winter safely in frozen soil layer at 25ー40 °C. RHIZOME tuberous. Stem distally branched, covered with short hispid or SETAE. Basal leaves opposite, upper leaves alternate, long ovate * ovate-elliptic, 10-15cm long, 3-9cm wide, 3-veined, upper surface rough, lower surface pilose, margin serrate, apex acute or Acuminate, base broadly cuneate, petiole narrowly winged. Cold and drought resistance, tubers in-30 °C in the frozen soil layer can be safe over the winter. Early Spring Seedlings Can Bear Light Frost, autumn leaves can bear short-4 ~-5 °C. In temperate zone, 18 ~ 22 °C and 12 hours illumination were favorable for tuber formation. Poor tolerance, the soil requirements are not strict, in addition to acid soil, marshes and saline-alkali areas not suitable for cultivation, some not suitable for cultivation of other crops, such as ruins, curtilage, roadside can grow.
