After the Spring Festival, the province's snow-shaking weather has soared. The numerous snowflakes have caused inconvenience to the agricultural production in the greenhouse. How to manage the sheds after the snow and ensure safe production are particularly important. We have compiled this draft for the reference of the farmer's friends who are involved in the production of greenhouses. I hope I can help you. --editor
Reinforce the booth to clear the snow
Winter snowfall, especially snowfall at night, occurs when the snowfall on the grasshopper or shed film exceeds the maximum pressure on the shed's skeleton. Therefore, the snowy area should be cleared of snow in time. For some penthouses with large spans, few columns, and no columns, it is necessary to add temporary columns to support the arches in the snow days.
Protect grasshoppers properly
Once the grasshopper is wet with snow or dew, it becomes a heat absorber, which will greatly reduce its cold insulation. Covering the grasshopper with a layer of film can reduce the heat loss in the shed and prevent the rain and snow from soaking the grass and reduce the heat preservation. In addition, cloudy snow days, due to the thick clouds in the sky, the temperature is generally not very low. In order to protect the grasshoppers, it is not necessary to cover the grass in the snowy days. After the snow stops, the snow on the shed is cleaned and the grass cover is added at night.
Snowy weather
As the saying goes, everything grows on the sun. Some large shed households are not exposed on cloudy snow days, and they are not even exposed for several days. The reason is that they are afraid of freezing seedlings. Although there is no direct light on cloudy days, the scattered light through the clouds can also increase the temperature in the room. It was determined that the temperature in the shed room was increased by 2-3°C after the cloudy snow cover. What's more, if the plants do not see light for a few days, they can easily become infected with "yellowish yellow," which can lead to death.
Strengthen moderate ventilation in cultivator
Due to the low temperature in the winter and less plant growth, the amount of fertilizer needed and the amount of water needed are also less. However, cultivating ridges often requires cultivating soil to increase the soil temperature and discharge carbon dioxide and some harmful gases released from the decomposition of fertilizers in the soil, allowing fresh air to enter the soil layer and promote root growth. The method of covering all fields with plastic film is not desirable, and methods that only cover ridges and often cultivating wide ridges should be promoted. Prompt ventilation and reduction of the humidity in the shed are important means for preventing the occurrence of diseases. However, the focus of the management of winter booths should be on the heat storage and heat storage. If the ventilation time is too long for the purpose of dehumidification and the indoor temperature is low, the plants are more susceptible to disease.
Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
