When the snow storm hits, the outside temperature is lowered, and under the premise of ensuring the safe and firm shed, the greenhouse insulation work must be highly valued. The shed did not collapse, but the temperature of the shed was not guaranteed. The vegetables were frozen and could not be recovered for a long time. Insulation measures could be taken in advance, such as covering two layers of grass worms and adding a layer of film, ridging the film to cover the shed, shed. For the first time, farmers can use their own skills to learn from the past, such as covering the grass, burning the corn cob, or using electric wires. In addition, under cloudy snow weather, the greenhouse insulation can start from other measures. Cleverly Membrane Reinforced Thermal Insulation One night before the blizzard weather arrives, the vegetable peasants will be able to cover the sheds early. How to save time and effort to cover the film, there are many doors. Usually, the vegetable farmers pull down a whole piece of plastic film from the east-west wall of the greenhouse to the front face of the greenhouse, or pull it up from the front face of the greenhouse to the wall of the greenhouse. The weather is often before the arrival of heavy snowfall. Large, it is very difficult to pull the film. The method is to divide a whole piece of film into two pieces. A nylon rope is pressed into the film along the mucous membrane. When the film is covered with a film, the film is pulled directly from both sides of the gable to the middle of the greenhouse. Lay the pressure, and then press the film on the front face and the back wall of the greenhouse with a half-full sandbag. Press the bag every 5 meters to ensure that the wind will not be poured into the film. When selecting the film, it is better to choose black and absorb heat. According to past years of experience, after the snow, the frozen water on the film is not easy to melt, it is difficult to peel off the film, and it is easy to cause film damage. It is better to choose a black film. After the sun comes out, it shines on the film. The black film Warming faster than white film, so snow melts faster. Adding straw reactor to increase ground temperature The corn stalks are piled in rows between the cucumbers, and the root bait and high-fertility microbial agents are sprayed at the same time. The ground temperature is increased by the heat released by the microbial fermentation activity. This technology is called a straw reactor. At present, the technology is widely used and has a significant effect on raising the ground temperature in the deep winter. A vegetable farmer had done experiments, and after setting up a straw reactor, the ground temperature was 2 to 3°C higher than that set. For the thermophilic vegetables such as cucumbers and peppers, it is of utmost importance to increase the ground temperature in the winter to 2~3°C, which can promote the growth of the root system and increase the overall yield. Improve the cold resistance of vegetables To improve the cold resistance of crops and avoid the occurrence of chilling and freezing injury, we can start from two aspects: Conservation of the root system: the plant roots are like the heart of a person. If the heart function is weak, the body is poor. If the roots of the plants are weak, the supply of water and nutrients is limited, and the plants are hungry all day long. How can there be strength to protect the disease? ? Therefore, the cultivation of vegetables in winter greenhouses is a core issue in management. Conservation of the root system does not happen overnight, but runs through the entire growing season of the plant. It is necessary to regulate and control the suitable greenhouse temperature and humidity environment, water and fertilizer supply, and plant adjustments. Conservation of leaves: low temperature in cloudy snow weather, affecting the absorption of mineral nutrients by roots, leading to the lack of inorganic nutrients, weak photosynthetic enzyme activity; weak light in the shed, lack of energy, limited photosynthesis of plants, insufficient organic nutrition, In the absence of both inorganic and organic nutrients, the disease resistance of the plant itself can be imagined. Before the arrival of heavy snowfall, spray full of chitin, alginic acid, photosynthetic power, and multi-nutrition foliar fertilizers to supplement leaf and much-needed trace elements and organic nutrients to alleviate the shortage of nutrients and improve the resistance of the leaves.
