Solar greenhouses and greenhouses, such as protected vegetables, often encounter adverse weather conditions such as cooling, continuous yin, fog, and snow in winter production, and poor management often results in huge economic losses. How to deal with these challenges, in addition to the winter before the reinforcement of greenhouses, greenhouses, repair and replacement of worn out waste equipment, should always listen to the weather forecast of the local meteorological observatory, know as early as possible, take active and scientific management measures to deal with the occurrence of natural disasters To minimize losses. The technical measures for protecting vegetables against various weather in winter are summarized below for reference. One, sunny management 1. Timely exposing late cover grass to extend the lighting time. After the sunrise, if the temperature of the shed is not lowered after it is uncovered, it is an appropriate time to dismantle it. In the morning, when the temperature in the shed rises to 30°C, open the shed film, ventilate, change the air, remove the temperature, and reduce the temperature. When the temperature drops to 26°C, close the vent immediately. The temperature in the greenhouse is generally 20°C to 21°C in the evening, the temperature in the greenhouse is reduced from 20°C to 16°C in the middle of the night, and is reduced from 16°C to 12°C in the middle of the night. The minimum temperature in the morning is not lower than 10°C, and the temperature in the greenhouse It is 3°C to 4°C warmer than the air temperature. 2. Dirty dust cleaning film to maintain the film's good light transmission performance. Hang lead-plated reflectors on the back wall to increase the light intensity on the north side of the booth and the lower layers of the plants. After watering, pay attention to ventilation and humidity, to reduce the fog and water droplets on the film to facilitate the transparency of the film. 3. Strictly plug gaps in greenhouses and reduce heat loss in sheds. Second, cloudy snow cold days management Pay attention to listening to the weather forecast and strengthen cold insulation measures in time before the cold snow and snow weather arrives. The grasshoppers should be covered in advance, and then a layer of film should be placed on the grasshoppers to prevent rain and snow from weeding and strengthen insulation. Closely ventilate the door and doorway to close the gap in the wall and stop watering. When the snowfall ceases, cover the snow on the awning, remove the outer floating membrane, and uncover the grasshoppers to scatter light. On cloudy days, we must also see the light and ventilate the ventilation openings and ventilate the ventilation openings around noon. However, the time for exposing the grass on cloudy days cannot begin too early and end too late. Generally, it takes 4 to 5 hours a day for daylight. Practice has proved that: Cloudy sheds in search of scattered light at the appropriate time on a cloudy day are 2°C warmer than those in non-disclosure sheds. Third, Lianyungengqing management After the continuous cloudy and rainy days have suddenly cleared up, we must not uncover the grass weeds. We must take measures to “disclose the flowers and spray warm water†to prevent flashing dead trees. The grasshoppers will be opened one at a time, so that there will be areas under direct sunlight and strong light, as well as scattered light areas. When wilting phenomenon occurs in the rapeseed field under direct sunlight, sprinkle warm water of about 20°C immediately, cover with grasshopper, and then uncover the previously covered grasshopper, so that the original area where the light is scattered is transferred. In order to receive strong direct sunlight, when the wilting of the vigorously shed pods occurs, it is immediately sprayed with warm water at 20°C and then covered with haystacks. If so, when the temperature in the shed rises to about 20°C, and the vegetable vines are no longer wilting, they can stop "exposing flowers and spraying warm water," and uncover all the grasshoppers and turn them into normal weather management. Pork is a very common meat in life, especially in China. Pork consumption is much higher than other meats and is the main source of meat. Pork tastes and tastes very good, it doesn't get tired when you eat it regularly, and it has a variety of practices. It can be delicious with a variety of ingredients.

Although the pork chop is made of pork, it has no fatty feeling at all, and it is particularly chewy. It is processed through many processes, not to fry or cook pork. The pork that is made out has a lot less oil, and the feeling of eating meat is particularly cool. The authentic pork chop uses the pig's hind leg meat. This part of the meat is mainly lean meat, and the fat is rare. It is more suitable for pork. breast
