1. Preparation: Lightweight plastic for seedlings, 60 cm in length, 25 cm in width and 5 cm in height. Cultivation of substrates with river sand or perlite, slag (maximum particle diameter not exceeding 2 mm). 2. Production: The suitable growth temperature for seed buds is 15-25°C. When the average outdoor temperature is higher than 18°C, it can be cultivated in open field, but it must be shaded and protected from direct sunlight. Select seeds with germination rate of more than 90%, soak in warm water of 55°C for 12 hours, remove and drain water, and germinate at a constant temperature of 22-24°C. After 2-3 days, the seed buds will be 1-2mm long. sowing. Before the seedlings, the seedlings were spread on a piece of paper at the bottom of the seedlings, and a layer of 2.5 mm wet washed sand was spread to evenly spread the seeds of the sprouts on the seedbed. Each plastic tray is sown about 0.32 kg, covered with a layer of 1.5 cm thick sand. 3, the preparation of nutrient solution and dosage: 5 days after sowing the buds grow out of the substrate, 10 days bud embryo axis length 3 - 10 cm, 1 mm thick, root length 5 - 7 cm with 10 kg of water plus 5 grams of urea, 5 grams of potassium dihydrogen phosphate, or compound fertilizer 400 - 500 times liquid with a nutrient solution spray. The relative humidity of the air should be maintained at 80%, 12 - 15 days harvesting, uprooted when harvested, cleaned and listed.
An Ambu bag is a manual resuscitator used in emergency situations to provide breathing support to patients who are not breathing adequately on their own. It consists of a flexible bag connected to a face mask or Endotracheal Tube, which is manually squeezed to deliver oxygen to the patient's lungs. Ambu bags are commonly used by healthcare providers such as in hospitals, ambulances, and emergency rooms.
