In winter, the production of colored peppers is less due to the emphasis on heat preservation, and the greenhouse is closed. The indoor and outdoor air cannot be convected. Because of the photosynthesis of the colored peppers, the concentration of carbon dioxide in the greenhouse is significantly reduced, so that the photosynthesis is also reduced. Therefore, it is necessary to supplement the shortage of carbon dioxide in the greenhouse by carbon dioxide fertilization, and enhance the efficiency of photosynthesis.
The carbon dioxide concentration is generally increased by using ammonium hydrogencarbonate plus dilute sulfuric acid to produce carbon dioxide. Put a plastic bucket in every 40 to 50 square meters in the shed, add 2 kilograms of industrial sulfuric acid to each barrel of 6 kilograms of water, and add about 250 to 400 grams of ammonium bicarbonate to the barrel every day at about 9 am. Ammonium bicarbonate was wrapped in a film, and then 3 holes were placed on the film with a 12 gauge wire to control the reaction speed of ammonium hydrogencarbonate with sulfuric acid. After more than 2 hours, the reaction of sulfuric acid and ammonium bicarbonate in the barrel can be completed. During this period, the air is not ventilated, and the tuyere is opened at about 12 noon for ventilation. It should be noted that the application of the room temperature above 18 ° C on sunny days is not applied on cloudy, rainy days and room temperature below 15 ° C. Generally, each barrel of dilute sulfuric acid can be used for 10 to 15 days.

Soy lecithin powder is a substance derived from soybeans that is commonly used as an emulsifier, stabilizer, and thickener in food products. It is a natural source of phospholipids, which are essential components of cell membranes. Soy lecithin powder is often added to chocolate, baked goods, and other processed foods to improve texture and prevent separation of ingredients. It is also used in the production of dietary supplements and pharmaceuticals. Soy lecithin powder is generally considered safe for consumption, although some people with soy allergies may need to avoid it.
