The weather in spring is fickle, and the management of the shed must also change!

    The sun is getting brighter, the rain is plentiful, and everything moves with the sun and the moon. Greenhouse vegetables have entered a vigorous growth period. It is necessary to be vigilant that although the temperature in most areas has risen, the temperature is unstable, and it is normal to fluctuate high and low. It is necessary to prevent the high temperature at noon on sunny days in the greenhouse, causing the phenomenon of "burning seedlings". Pay attention to the low temperature and cold damage caused by the rainy weather and the "cold spring" weather.

Prevention and Treatment of Cold Spring in Greenhouse

    Strengthen heat preservation, the "cold spring" weather will cause serious harm to the production of vegetables in spring, so it is necessary to do a good job of heat preservation and cold protection. Seal the holes and cracks in the greenhouse film to prevent the cold wind from blowing directly into the room from the vent to damage the plants.

Add thermal insulation

    The first is to erect a wind barrier, which can block the cold air and prevent the surface from further cooling; the second is to cover the multi-layer film, which can be covered with double or multi-layer insulation film; the third is to add a heating furnace or smoke , or set up warming bulbs to increase the temperature in the shed.

    watering method

    When the strong cold air passes, the weather is clear, there is no wind or breeze at night, and the temperature drops rapidly, a large amount of well water can be irrigated on the ground to greatly increase the ground temperature.

    temperature management

    Temperature management The plant's own cold tolerance and temperature-increasing and thermal insulation facilities are used to support the growth of overwintering greenhouse crops. Among the four elements of water, fertilizer, gas and heat, temperature is the most active factor for crop growth. Antifreeze to protect seedlings and heat preservation to promote growth are the top priorities of greenhouse overwintering management. Mainly from the aspects of enhancing the cold tolerance of the plant itself and the matching of warming and thermal insulation facilities.

    In order to do a good job in greenhouse management, many shed friends live and eat in the greenhouse, for fear of some mistakes. The traditional greenhouse management relies on experience and feeling. It is heated when it is cold, watered when it feels dry, and ventilated when it feels stuffy. There is no scientific basis.

    Nowadays, the Internet of Things has introduced the Internet of Things technology into the greenhouse, built an intelligent greenhouse planting system, and realized the efficient and precise management of greenhouse planting.

    System functions

    The intelligent greenhouse planting system can measure the environmental factors closely related to crop growth such as carbon dioxide, atmospheric pressure, soil temperature and humidity, air temperature and humidity, and light in the greenhouse, so that the greenhouse management personnel can find problems in time and take corresponding measures to effectively avoid them. production losses.

The intelligent greenhouse planting system can also properly adjust the environmental factors in the greenhouse according to the needs of crop growth, and can be operated remotely, which not only effectively reduces the labor intensity of personnel, but also reduces labor costs. More importantly, it improves the The yield of crops improves the quality of crops and increases the income level of farmers.

The intelligent greenhouse planting system uses its monitoring and control functions to create the best environment for plant growth, making the environment in the greenhouse close to the ideal value of artificial imagination, meeting the needs of the growth and development of greenhouse crops, and increasing the output value of greenhouse products and improving labor productivity. an important technical measure.
