First, the application of active fertilizers Fertilizers can activate the soil, improve the ability of fertilizer, and at the same time can coordinate the distribution of nutrients in the vegetable body, you can enhance the cold resistance of vegetable seedlings.
Second, sorghum cultivation, covering the film for the winter transplanted tomatoes, peppers, eggplant and other young bacteria, the soil before planting sheds should be raised into sorghum, and then cover the mulch, which can reduce the groundwater level, slow down the loss of heat at night, Insulation protection. The surrounding film must be covered tightly to prevent cold air intrusion.
Third, in the shed, a multi-layer covering sheds the vegetable seedlings to survive, but also puts a middle shed or a shed in the shed to effectively increase the temperature inside the shed.
Fourth, add additional curtains, cover grasshoppers and use curtains or old plastic films to make curtains outside the gates to prevent cold air from entering. In addition, grasses, etc. are formed on the four sides of the greenhouse to form an apron, which reduces the amount of heat in the shed.
Fifth, master ventilation time Multi-layered greenhouses warm up quickly in the sunny, in order to prevent the greenhouse high temperature, high humidity affect seedling growth, need to open the door to adjust the temperature and air, but due to the lower temperature in the early morning, generally have to wait until the temperature rise Ventilate the door again at 15°C, otherwise, premature ventilation will also produce frost damage.
