Artemisia halodendron is a perennial herb of the Asteraceae family and has extremely strong vitality. The main use of fresh stems for vegetables is because it is delicious, crisp, delicious, nutritious, and also has medicinal functions such as detoxification, prevention of toothache, and sore throat. It is popular among consumers and is a promising development. Seasonal vegetables. In Kunming, the main planting is mainly greenhouses, and the main planting species is Kunming dahurica. Because of the drought-fighting and heat-fighting, the optimum temperature is 20 to 25°C. When the temperature is higher than 25°C, the tender stems are likely to be lignified and affect the edible quality and yield of the commodity. Therefore, in Kunming, the cultivation pattern of the three-matured artemisia two-leaf vegetables is mainly adopted. Namely: a kind of wormwood, two wolfberry leafy vegetables such as cabbage, small green vegetables, spinach and so on. The main technical points for planting are as follows:
First, the preparation of fertilization: before planting tilling soil, deep plowing, smoothing, hoeing width 1.5 to 2 meters, 0.3 meters high. Due to the growth period and harvesting period of Artemisia selengensis, it requires long-lasting fertilizer, so it is required to redistribute the base fertilizer layer by layer: Generally, 667? Application decomposed organic fertilizer 3000-4000 kg or high-quality biological organic fertilizer 300-500 kg + ammonium bicarbonate 100kg + Superphosphate 50kg + compound fertilizer 50kg.
Second, cutting and planting: Choose the middle or late August or early September can be cuttings, cuttings to select stout thick, disease-free pest-free strains, remove both ends of the lignified and young parts, cut into 10cm long cuttings , leave 2 full shoots at the top of each segment. The lower end of the cutting is cut into bevels to prepare cuttings. The amount per mu is about 250-300kg. Fill the water 3 days before cutting. After the cuttings are selected, the ABT rooting powder 100-150ppm solution can be used to promote the rooting and improve the survival rate. Then insert 10 to 15 centimeters, 7 to 10 centimeters into the soil, and leave about 3 centimeters on the ground. Press the soil tightly after plugging in. Immediately irrigate the water, and then re-irrigate the water on the 3rd. The total cutting and planting requirements are as follows: the plug is not inserted, the plug is not plugged in, and the plug is not plugged.
Third, field management: when the seedling length is 3-5 cm, the mu application of urea is 10 kg, and the input compound fertilizer is 10 kg. The tender stems can be harvested when they reach a height of 30-40 cm, and then harvested once every 40-45 days. 3 times, the general harvest before the Spring Festival twice, harvested once in March, acres can be harvested about 2500 kilograms of clean vegetables, the average unit price of 10/kg, harvested with a knife to cut. For each harvest, use only 0.5 kg of potassium dihydrogen phosphate or 0.5 kg of urea for spraying. Pay attention to keep the soil moist for a long time and remove the weeds in time.
Fourth, a reasonable stay in the species: After the last harvest in March, choose to reserve seedlings field, generally leave 1: 5 area. The management methods of the remaining farms are the same as above.
5. Rational rotation: In addition to leaving the fields, we must promptly turn over the fields to expend field crops, and after removing the debris, we must sow small vegetables such as bok choy or spinach and other fast-growing vegetables. The management method is the same as conventional planting. Generally, two plantings can be planted before the next season. Seasonal lettuce. An average of 1200 kilograms of vegetables can be produced per season, which can also produce considerable economic benefits.
