Artemisia halodendron, spring green soybeans, and green vegetables planted in a greenhouse
I have been exploring the greenhouses of Artemisia selengensis, spring soybeans, green vegetables three crops a year high yield and efficient cultivation mode, has been promoted nearly 2,000 acres. Generally can produce 1000 kg of Artemisia per ha, 500 kg of green soybeans, 600 kg of green vegetables, with good economic benefits. 1. Variety selection Artemisia selengensis uses early-maturing, high-yield, cold-tolerant and strong-vegetative species of green leafy stems. Soybeans use precocious, large-grained, high-protein high-quality varieties such as Ningshu 60, Taiwan 292, which are selected for heat resistance and strong resistance. Dwarf No. 1, heat resistance and other varieties. Second, the width of the greenhouse is 6 meters. Artemisia halodendron is planted in the middle and late July, and will be placed in the shed in early December. It will be listed from January to early March. The early soybeans will be planted in the greenhouse in early March and harvested from the end of May to the beginning of June. Small vegetables will be sown in mid-June. The harvest ended in mid-July. Third, the main cultivation techniques 1. The ratio of Artemisia ordosica seedlings to Daejeon is 1:10. Loose, fertile and well-maintained sandy loam soil plots are planted. Avoid continuous cropping. Before planting, apply 3000-4000 kg of organic fertilizer per acre, 75-100 kg of cooked cake fertilizer, and 30% of urea as base fertilizer. The Artemisia oryzae harvested or harvested only once last year was used as seedlings. When planting, cut the top of the young shoots of Artemisia, leaving 15-20 centimeters for each branch. According to the spacing of 40 cm, planting spacing of 25-3O cm, planting 1-2 sticks per hole, pressing the soil after planting, irrigating the water. Before sowing, use trifluralin for soil treatment, or use GaiSuoGeng and JingLouKe to control weeds. Insect pests can be controlled by insecticide-resistant, all-spirited and other agents, and timely replenishment in high temperature and dry weather to keep the field moist. In mid-August and mid-September, the plant vigor can be visualized, and the fertilizer can be applied twice in combination with watering. Generally, 10 kg of urea is applied per mu. At the beginning of December, when the temperature dropped below 15°C, the above-ground part of Artemisia halodendron was cut off, and 3000-400 kg of manure fertilizer or 50 kg of organic compound fertilizer was applied per acre. The membrane was delaminated every 5-7 days. Greenhouses, compacted around the greenhouse. Shed temperature is controlled at 20-25°C during the day, 12-15°C at night, and humidity is controlled at 80%-90%. When the above-ground stem of Artemisia halodendron grows to a height of 10-15 cm, spray 30 ml of brightener and 2.5% thickening agent in a gibberellic acid solution with a concentration of 80x10-6-l00x10-6. When stems grow to 25-35 centimeters in height, they are cut off and marketed. Generally, they can be cut 2-3 times. 2. Before the early soybeans were sowed, 2000 kg of organic fertilizer and 50-75 kg of vegetable-specific fertilizer were applied per acre. According to the line spacing 30 cm x 30 cm or 40 cm x 25 cm sowing, sowing seeds 2-3 per hole, sowing rate of 6-7 kg per acre, after sowing permeable water and film, film around the mud compaction. Immediately after emergence, the seedlings were broken and the seedlings were planted in a timely manner, leaving 13,000 to 16,000 plants per mu. Soybean mid-growth to promote flower fertility, sorghum drum grain fertilizer, combined with water per acre 10 kg of urea. 15 days before the harvest, the concentration of 0.3% -0.5% potassium dihydrogen phosphate solution, the concentration of 1% -2% of the urea solution or Huimanfeng 300-400 times solution for extra-root fertilizer. Pay attention to pest control. 3. After vetching the green soybeans, the soybeans are used to make soil. 1 day before sowing, watering, per acre sowing amount of 1-1.5 kg, after sowing light cover seed manure water, take a 40-50 cm high in the surface of the frame, covering the shade net high temperature. During the growing season of vegetables, it is necessary to chase diluted manure water several times. Timely control of cabbage caterpillars, diamondback moth and other pests.
