First, the late management of seedlings mainly focuses on the three links of humidity, disease prevention and temperature control. According to the situation of most of the township seedlings, the general humidity in the greenhouse is too high, and the method of dehumidification is as follows: First, sprinkle some pre-prepared fine mud; second, the small sunny ring film is opened. Disease prevention and control: The focus is on cross-spraying of bacillus-like medicine, prevention of damping-off, and reference to the technical requirements for the total 107th period for the prevention and control of other diseases. Temperature control, in the late should pay attention to control at about 20 °C as well. Second, Daejeon's preparation before transplanting 1. Plow up the land, apply enough basal fertilizer and make a good head. In general, each plot applies 20-30 watts of organic fertilizer, 50 kg of compound organic fertilizer, 50 kg of phosphate fertilizer, and 3 kg of biological pliers. 2.è¶ There is no wind or small windy weather, cover a large film of greenhouses, and prepare a small ring of rings and covered nylon, covered with plastic film (preferably black plastic film). Under normal circumstances, the door to the north of the greenhouse should be sealed off to ensure the temperature. 3. Three ditch around the greenhouse. Third, seedlings planting seedlings in the 2-3 leaves 1 heart, can be planted (usually control the age of 30-40 days). On the taro, the plants were broken and planted with 30-35 cm of plant spacing, and two plants were planted in the greenhouse. After planting, fill the roots with 3% urea solution and seal the planting mouth. In the colonization ridge on the 30-40 cm high, 50-120 cm two-story small arch insulation, conducive to live trees. Fourth, management requirements 1. Make sure the temperature. The temperature after transplanting should be around 30-35°C. In the method, the temperature is maintained by a greenhouse film, a small ring cover film, and a plastic film. When the temperature is particularly low, a straw curtain or a non-woven cloth can be used to increase the temperature of the frost. 2. Ensure normal temperature. After the live tree, it is necessary to pay attention to the temperature at noon from the noon, and the temperature should not exceed 35°C. If the temperature does not drop, consider re-opening the south gate of the greenhouse. 3. Timely top dressing. When the melon vine grows to 50 cm (usually after the end of March) in 50 cm from the root of the melon (see self-root) on both sides of the ditch, the application of compound fertilizer or cake fat, the best use of special fertilizer such as glutinous rice, etc., and cover soil Leveling. 4. Grasp pruning. Prevents growers from going crazy. Generally, each plant stays 2-3 vines (depending on the transplanting density), which is the key to the success of the cultivation of the spring melon in the spring, and the other side branches must be determined to cut off all. Before and after the beginning of summer, a small shed was spread (the vine had been to the side). 5. Artificial pollination. At 6-10 o'clock in the sunny morning, pick the male flowers that are well developed and pollen-free, remove the petals, and gently apply evenly on the female flower heads and mark them. 6. Select guagua melon. Choose to leave about 14 leaves melon, only one melon per plant, in order to facilitate premature and strong. 7. Swelling fruit fertilizer. One week after the first batch of melon fruit, apply the swelling fruit fertilizer, which can be urea, and the best watermelon special fertilizer. After that, 0.5% dihydrogen phosphate solution was sprayed every 7 days, and the soil was kept moist. The moisture was controlled one week before harvest to improve quality. 8. Pest control. It is necessary to constantly control sperm and virus diseases caused by it.

The status of management of nosocomial infections in gastroscopes:At present,the gastroscope,biopsy forceps cleaning,disinfection,and sterilization have not received enough attention.China is a high-risk area of viral hepatitis.Among all the country,the infection rate of hepatitis B virus is 42.4 % to 80.7 %;the detection rate of human HBsAg is 10 %,and the annual incidence rate is 230/100,000.At the same time,the number of HIV infections is rapidly increasing. Some hospital patients have not detected any infectious diseases before gastroscopy.AIDS patients often conceal their medical history when they visit the clinic.During the process of gastroscopy,they can easily cause nasal mucosa and upper digestive diseases.Oral mucosal bleeding,or because of poor blood coagulation mechanisms in patients with liver disease, leading to gastric mucosal bleeding,blood containing hepatitis B and other viruses will pollute the pipeline, such as gastroscopy,biopsy forceps sterilization is not complete,will cause pathogenic microorganisms The survival and reproduction of other patients,the pathogenic microorganisms can invade the human body through the damaged mucosa,causing iatrogenic infection,especially hepatitis B virus and HIV.
