Artemisia halodendron three-year broadcasting technology
Artemisia halodendron, commonly known as wormwood or basil. It can be planted for three seasons each year. It can be cultivated in spring and autumn and can be grown in the winter. It can be harvested in three quarters per season and yield about 1,500 kilograms per mu. First, open cultivation techniques 1, sowing date: Artemisia glutinosa hi cold climate, strong adaptability, spring sowing too easy to twitch, exposed the best sowing date to the vernal equinox; autumn sowing in white sowing. 2. Seeding method: Before convulsions or white dew, the land will be well-grounded and the amount of mu will be about 0.85 kg. After pouring water, dry seeds are sown. Autumn sowing can also soak the seeds with water for a day and night, remove them and put them in a ventilated and shady place to dry. Row spacing is 3.5 cm. 3, harvest: spring sowing cabbage, small seedlings before the full height of 20-23 cm, leaving 5 cm after cutting off the tender shoots, harvested once every 15 days, received a total of 3, after the summer heat, stems and leaves can no longer cut, Can not stay seeded. 4, management points: 1 will be when the seedlings, to be a Qiaomiao water; Qimiao, if the seedlings are too dense, can be used ten-toothed fleas lightly again, sparsely a part of the seedlings; seedling height 3.5 cm to 3.5 cm square Dingmiao; 2 seedlings and after each harvest, each forced application of urea 10-15 kg; 3 seedlings should be less watering, soil moisture should be maintained in the late growth; 4 timely weeding. Can use 25% of herbicide ether 0.25-0.5 kilograms, 60 kilograms of water, evenly spray with a sprayer, should often stir the liquid to prevent precipitation, so as not to affect the effect; can also be required dose per mu water 400 kg, with pot Sprinkle; or 0.25-0.5 kg of herbicidal ether and 25 kg of fine soil or fine sand and mix evenly in the field. Generally should be applied after sowing, before budding, two days after the drug can not be watered, 7 days can not escape; 5 do not even make. Second, the protection of cultivation points 1, autumn seedlings, after the winter can be buckle shed, after the shed to be properly controlled water, air cooling, humidity, to prevent rotten leaves. Before and after the Snow Festival, the first crop was harvested, and depending on its growth, the second crop and the third crop were harvested at the end of December and the end of January. 2, winter sowing in mid-November soaked seed germination, in the small snow festival before sowing in the greenhouse. After emergence, we must cultivate, weed, and keep hoe in time. In the early period, we must pay attention to protecting wintering and raising roots and strong seedlings. In the later period, we must strengthen management, accelerate growth, and mention the morning market. We will strive to harvest the first crop in early March and collect the second and third crops in the late March and April 15th. 3, the temperature requirements and adaptability range of garland chrysanthemum in protective cultivation. The optimum temperature for the growth of Artemisia selengensis is 186 °C, the maximum temperature it adapts to is 30 °C, and the minimum temperature is 2 °C. China Agricultural Network Editor
