Key points of cultivation and management of coriander in autumn

Coriander is also known as coriander, salt coriander, stars and so on. For umbelliferae coriander is an annual herb. Originally called Coriander Herb, Coriander is native to Central Asia and Southern Europe, or the Near East and Mediterranean. Cultivation techniques and pickling methods are recorded in Qi Min Yao Shu. Its tender stems and fresh leaves have a special fragrance, often used as a dish embellishment, taste of goods.

Morphological characteristics of coriander

Annual or biennial, strongly odorous herb, 20-100 cm tall. Roots spindle-shaped, slender, with numerous slender branching roots. Stems terete, erect, much branched, striate, usually smooth. Root leaves stipitate, stalk 2-8 cm long; leaf blade 1-or 2-pinnatisect, pinnae broadly ovate or flabellate, 1-2 cm long, 1-1.5 cm wide, margin obtusely serrate, notched or deeply lobed, upper stem leaves 3-or multipinnatisect, ultimate segments narrowly linear, 5-10 mm long, 0.5-1 mm wide, apex obtuse, entire. Umbels terminal or opposite leaves, peduncle 2-8 cm long; rays 3-7, 1-2.5 cm long; involucrules 2-5, linear, entire; umbellules with pregnant flowers 3-9, white or lilac; calyx teeth usually unequal in size, small ovate-triangular, large long-ovate; Petals obovate, 1-1.2 mm long, ca. 1 mm wide, apex with concave lingula, radiating petals 2-3.5 mm long, 1-2 mm wide, usually entire, 3-5-veined; filaments 1-2 mm long, anthers ovate, ca. 0.7 mm long; styles erect when young, reflexed outward when ripe. Fruit spherical, abaxial main rib and adjacent secondary rib obvious. endosperm ventral concave. The oil pipe is not obvious, or there is one located below the secondary edge. The flowering period is from April to November.

Key points of cultivation and management of coriander in autumn

1. Select land, apply sufficient fertilizer and prepare land carefully

Coriander growth period is short, the main root is stout, the department shallow root vegetable, and the bud soft top strength is poor, the absorption fertilizer ability is strong. Must choose in drainage good, fertile loose, water and fertilizer loam, can use early tomatoes, cucumbers, beans and so on for the previous crop. Before planting, apply 3000 - 5000 kg of decomposed farm manure every 0.1 hectares with ploughing, rake fine and level to make beds, generally 1 meter wide, bed length depends on terrain and water source, which is beneficial to planting management, thus promoting root absorption and robust growth of plant protection. II. Sowing

Coriander varieties have large leaves and small leaves. Leaflet cold resistance strong, strong flavor, raw food, seasoning and pickling can be suitable for autumn planting. The seeds are hemispherical and surrounded by a pericarp. Before sowing, the seeds should be rubbed open to prevent slow germination and double seedlings, affecting the growth of individual plants. Like cold, not hot, early sowing temperature is high, easy to sprout flowering, fiber, reduce yield and quality, lose commodity value. Late sowing, short growing period, low yield. The suitable sowing time is after the middle of August. The row spacing of drilling is 10 - 15 cm, the depth of furrowing is 5 cm, and the depth of sowing is 4 cm. Drill sowing, sowing evenly cover soil 2 - 3 cm, 0.1 hectares with seed quantity 5 - 6 kg. After sowing, step on it once, then water it to keep the soil moist and facilitate seedling emergence. At the same time, attention should also be paid to the phenomenon that the seedlings do not emerge due to the soil hardening before the coriander emerges. Check the seedlings in time after sowing. If the seedlings are found to have soil hardening when they emerge, spray water and loosen the soil to help the sprouts emerge and promote rapid growth. III. Field management

In order to create soft and comfortable growth environment and favorable living conditions for coriander growth and development, and to achieve proper temperature and humidity management, it is the key to cultivate, loosen soil and weed carefully for many times. When the seedlings grow to about 3 cm, thinning and seedling determination are carried out. Generally, the whole growth period of cultivation, loosening, weeding 2 - 3 times. For the first time, when the seedlings are on top of the soil, use a light hoe or a small rake to gently break the soil and loosen the soil to eliminate the hardened layer. At the same time uproot early weeds to facilitate the emergence of seedlings thrive. The second time in the seedling height of 2 - 3 cm, and the drill can be used to hoe the appropriate deep soil, combined with pulling out weeds. The third time is when the seedling height is 5 - 7 cm. This early cultivation, loosening, weeding, can promote vigorous growth of seedlings. After the leaves are sealed off, no matter whether it is drilling or sowing, there is no longer cultivation and loosening, but only a few targeted plowing. Coriander is not drought-tolerant, it must be watered every 5 - 7 days, basically watering 5 - 7 times during the growth period of the whole plant, and often keeping the soil moist. 0.1 hectares in the middle of growth, urea 15 kg to ensure good growth. IV. Harvesting and Storage

Parsley can be harvested 30 days after sowing at high temperatures and 40 - 60 days after sowing at low temperatures. Harvesting can be inter-plucked, but also a harvest. In addition to recent consumption, it can also be stored for winter and spring consumption. The method of burying soil and freezing is adopted for storage. Before eating, take it out and put it in a place of 0 - 10℃, slowly thaw it, and still keep it fresh and fresh, and the color and taste are not reduced.
