One is to fill light.

At present, the use of reflective film is advocated in production. This is a kind of polyester aluminized film. When it is used, it cuts the corresponding length of the reflective screen in accordance with the length of the greenhouse, and uses a transparent tape to bond and fix the two single-beam reflective screens. Then hang a No. 6 wire in the direction of east-west direction on the middle column or north wall of the greenhouse, turn the upper end of the reflective screen back to wrap the wire, and fix it with a pin or a bright tape so that the light curtain will naturally hang down and make the aluminum-plated light shining. On the one hand, face the south, fold back 3 to 5 centimeters below the reflective screen, use a hemp rope as a backing rope, and tie a bamboo stick on both ends of the rope so that the reflective screen can maintain an angle of 75 to 85 degrees with the ground.

The second is supplementary coverage.

For the thermophilic crops such as peppers, eggplants, tomatoes, melons, etc., pay attention to supplementary coverings from December to mid-February. The more common method is to use a small shed cover in the greenhouse. If the weather is very cold, black mulch can be covered at night, or straw drapes can be used. The warm-weather vegetables sown on the lunar month can be covered with double membranes. When the weather turns fine, pay attention to ventilation to cool down or reduce the membrane after the temperature rises.

The third is supplement gas fertilizer.

In winter, the temperature is low, organic matter in the soil is decomposed to release less carbon dioxide, and greenhouse vegetables often lack carbon dioxide in the middle and later stages. Therefore, the following methods can be used to supplement nitrogen fertilizer according to the situation: First, deep application of ammonium bicarbonate can release carbon dioxide. Generally, 10 g of ammonium per square meter is applied, and the depth of fertilization is 5 to 8 cm; the second is the burning of biogas. The use of biogas lamps or biogas furnaces that are fully-combusted as discharge appliances can be used to release carbon dioxide concentrations in the shed to 1‰ to 1.2‰ after the daily sunrise. The greenhouses are also closed for one and a half or two hours until the shed is reached. The temperature is raised to 30c and then the greenhouse is cooled; the third is the chemical generation method. Forty ceramic containers were placed uniformly in every 667 square meters of shed. First, a 98% concentration of industrial sulfuric acid and water was diluted 1:3 and then distributed into each container. Each device contained 0.5 kg of solution. 30 grams of ammonium bicarbonate was added 30 minutes after sunrise each day, and a dilute sulfuric acid solution was added for 3 days to add ammonium bicarbonate.
