How to artificially domesticate sand scallions? Artificial domestication and cultivation management technology of scallions
Shallot can also be called Mongolian oak, a perennial herb that grows in the desert. Leaves and flowers can be used. The aerial part can be used medicinally. It has appetizing, digestion, insecticide, treatment of indigestion, no diet, baldness. Sore, green leg disease and other effects can also be used as livestock feed, followed by Xiaobian to talk about the artificial domestication of planting management techniques. 1 life habits Suitable temperature for growth of scallions: 12-26 degrees; When the summer drought occurs, growth will stop, and the precipitation will grow rapidly; When exposed to strong light, the tip of the blade will appear dry and reduce the applicability. The scallions have strong drought and cold resistance. 2 Shallot cultivation technology 2.1 Land leveling Before planting, the whole land is deeply cultivated, using farmyard manure and compound fertilizer. Each shed is applied with 1200-1500kg of sheep manure + a small amount of compound fertilizer, and then 20cm of fine sand is applied to the water. 2.2 Planting time Generally choose April or September, the best seeding after the film is released in September; The temperature is high in July and August, and it is not allowed to sow after the film is released from the greenhouse. It is easy to cause the sun to die after sowing. 2.3 Planting methods Planting method: using ditch seeding or hole seeding; Before sowing: water should be poured before planting, and the soil can be sown by hand with the soil. When sowing: the sowing depth is 2-3cm, the distance between crops is 15-20cm, and the seeding amount per hole is 20; After sowing: the ditch is leveled with a wooden handle, slightly pressed and watered, and the beta-cypermethrin emulsifiable concentrate is applied to kill the underground pests. 2.4 Field Management Management of scallions in the field includes watering, weeding, temperature and humidity control, as follows: a. The amount of water needed in the vigorous period of the onion is large, and it is necessary to provide sufficient water source and apply a certain amount of organic fertilizer and decomposed sheep manure. b. Water is poured every 10-15 days in the season of the greenhouse; in winter, water is poured every 20 days; on average, two water is poured every time. c. Precautions for watering: When watering in winter, it is necessary to control the amount of watering. Too much watering will cause water in the roots of the sand onions and poor permeability of the soil, causing the scallions to die. d. At present, no disease has been found in scallions. If disease is found, mild phoxim can be used for prevention and treatment. e. When harvesting scallions, it is strictly forbidden to trample the plants. 2.5 Shallot harvesting time When the onion grows to 20cm, it can be harvested; Harvesting with a sharp knife or scissors from the ground 1cm; Packed immediately after harvesting and sold on the same day. 3 Economic Benefit Analysis The scallions are calculated according to 6-8 yuan/kg per shed, 250 harvests per raft, 1,500 yuan in summer harvest (April-September), and 7 500 yuan in Wuyi; 11-The second year of March is the winter harvest, the market is 30 yuan, the income per unit is 7,500 yuan, and the total income of the four units is 30,000 yuan; A greenhouse has a annual income of 37,500 yuan, minus the cost, and the net income is more than 30,000 yuan. 4 Management after harvesting The scallions need to be dehydrated for 2-3 days after harvesting; After harvesting, do a good job of watering, fertilizing and ventilation.
